Colloidal Silver is a powerful, natural antibiotic and can be used to prevent and treat common infections. It can be ingested internally, used topically for skin conditions, and commonly used as an active ingredient in creams, gels, shampoos and conditioners.
It can also be used on pets and even plants, is non-toxic, and contains no heavy metals or interact with any medications.
How Silver works
Silver interrupts the bacteria cell’s ability to form the chemical bonds essential to its survival. These bonds form the cell’s structure, so when the bacteria encounter silver nanoparticles it literally falls apart.
It has antimicrobial properties, meaning it is antibacterial, antifungal, and antiviral. Many strains of pathogenic microbes, viruses, fungi, bacteria or any other single-celled pathogens that are resistant to other antibiotics are killed on contact by Colloidal Silver, and are unable to mutate. They are then cleared out of the body naturally by the immune system.
Acting as a catalyst, it disables the enzyme that one-celled bacteria, viruses and fungi need for their oxygen metabolism. They suffocate without corresponding harm occurring to human enzymes or parts of the human body chemistry. The result is the destruction of disease-causing organisms in the body and in the food.
The presence of Colloidal Silver near a virus, fungus, bacterium or any other single celled pathogen disables its oxygen metabolism enzyme, and within a few minutes, the pathogen suffocates and dies.
Unlike pharmaceutical antibiotics, which destroy beneficial enzymes, Colloidal Silver leaves these tissue-cell enzymes intact, as they are radically different from the enzymes of primitive single-celled life.
Colloidal Silver does not weaken the body’s immune system. In fact, it is said to give the body a second immune system, creating a shield against disease of all kinds with its antimicrobial properties.
A short history of using silver
The antibacterial properties of silver have been known for thousands of years. The ancient Phoenician, Greeks and Romans cooked from silver pots and kept wine, water, and vinegar in silver containers to keep liquids fresh. Ayurvedic, Chinese and homeopathic practitioners use silver regularly. Throughout history, aristocratic families have eaten with silver utensils, plates and cups, as it was proven to be more hygienic. This gave rise to the term ‘born with a silver spoon in your mouth’.
Silver has been used to heal wounds for more than a century. It was used in the First World War for dressings, as silver promotes the growth of new cells, it can to speed the healing process.
Many companies today use silver as an active ingredient in the manufacture of commercial dressings, bandages and creams, and hospitals embed silver into surgical tools, catheters, needles, stethoscopes to help eliminate infection.
Up until the 1930’s medical doctors used Colloidal Silver extensively as an antibiotic. However, during this time the cost of producing highly effective Colloidal Silver was high, and the pharmaceutical industry was looking to more affordable and more importantly, patentable options for an expanding population.
Colloidal Silver subsequently fell out of use for a number of decades until the 1970’s when doctors rediscovered the wound healing capabilities after trying many other medicines. In the 1980’s, researchers found that bacteria, virus and fungus organisms died within minutes of contact with silver. NASA used a silver water purification system for their space shuttle.
As Colloidal Silver doesn’t sting the eyes, it often replaces chlorine in swimming pools and spa pools. Many modern airlines use silver water filters to stop the spread of waterborne diseases on aircraft.
It can be taken on its own, either internally or topically or it can be added to other natural ingredients such as aloe vera, or New Zealand mānuka honey or kawakawa to further enhance their own antibacterial properties.
How Colloidal Silver is made
As silver is prohibitively expensive to apply to consumer products, research found that using nanoparticles of silver was a practical way of using the antimicrobial properties of silver to use across a range of applications.
The smaller the size of the nanoparticles the more effective it can be, as they have a larger surface area relative to their volume. They can therefore interact with more particles and increase their antibacterial activity.
Colloidal Silver is made by an electromagnetic process that extract nanoparticles of silver from a larger piece of silver into a liquid, such as water. The particles are then suspended and evenly dispersed in the water, giving it the name ‘colloidal’ silver.
These microscopic particles can then more easily penetrate and travel throughout the body, killing all types of fungal infections, bacteria and viruses, including strains that are resistant to antibiotic drugs.
How do I take it?
Colloidal Silver can be either taken internally or applied topically to the skin. When feeling unwell or in need of an immune system boost, take 5ml of liquid three times a day for five days, then 5ml per day thereafter. Children under 8 years of age take half adult dose. This will assist your body’s natural defences against bacterial or viral infections such as colds or flu.
Always use a plastic spoon as metal affects the positive charge of the silver ions. Do not store in a refrigerator, near a magnetic field or an electronic device.

Skybright Colloidal Silver Cream has the additional antibacterial, antifungal and antiviral benefits of New Zealand mānuka honey and mānuka oil to support the body’s natural response. The blend of emollients and nourishing, vitamin-rich avocado and jojoba oils are absorbed quickly, leaving skin feeling hydrated and revitalised.
Our newly reformulated and upgraded Cream uses only the best organic ingredients and are now silicone-free.
Although ideal for healing damaged skin and managing many common skin conditions, it is often used as a daily moisturiser or night cream, helping to heal spots and blemishes while hydrating the skin.
Use it topically for skin related issues such as mild dermatitis, eczema, heat rash, topical yeast, itchy skin, athlete’s foot, ringworm, dry/chafed skin, cuts, bites and minor burns. Suitable for all skin types and all the family, including children and pets.
The active ingredients:
Mānuka Honey & MānukaOil Our Colloidal Silver Cream contains high-grade New Zealand Mānuka Honey, which is an antioxidant, as well as antibacterial, anti-inflammatory and antifungal. Mānuka is a native plant of New Zealand, and is well-known for its healing properties and benefits to the body as a whole. Mānuka Oil has higher antibacterial and antifungal activity than tea tree oil.
Avocado Oil As well as being a rich source of beta carotene, vitamin A, D & E, avocado oil has fatty acids, so the top layer of skin is bound together by fat molecules, which help it retain moisture, stimulate cell turnover and protect against sun damage. Fatty acids can also mitigate the appearance of fine lines and improve skin tone.
Avocado Oil has antioxidants and anti-inflammatory agents that help your skin stay smooth and strong while providing elasticity. It also penetrates the skin more deeply than other oils and stimulates collagen metabolism which helps reduce signs of ageing and accelerates the healing process.
Jojoba Oil Also rich in essential fatty acids, vitamin E and antioxidants, jojoba oil can penetrate deeply into the skin, to deliver moisture and tackle underlying issues of dehydration as well as surface dryness. The anti-inflammatory properties can help soothe the skin post-sun exposure, while natural antibacterial properties help clear existing blemishes.
Citrus Fruit Extract A potent and effective broad spectrum bactericide, fungicide, antiviral and antiparasitic compound. It’s useful in the treatment of skin infections, including acne and dermatitis. Great for itchy skin, athlete’s foot, ringworm, dry/chafed skin, cuts, bites and minor burns.
Colloidal Silver Colloidal Silver is very fine particles of 99.9% pure ionic silver suspended in purified water. It supports the immune system when the body is under attack and micro organisms cannot build up resistance. Apply it topically to take advantage of its antibacterial, antifungal and antiviral properties. It’s great for kids and pets and there are no known interactions or side effects if taken as directed.
Skybright independently tests every batch to ensure our Colloidal Silver meets our strict quality standards and comply with Medsafe requirements.
A new, all-natural, silicone-free formulation
As our new, upgraded formulation uses even more organic ingredients, it has a slightly more natural colour than the previous Cream. It uses the same powerful but gentle active ingredients, but no longer uses silicones as a preservative.
We now use Dehydroacetic Acid and Benzyl Alcohol, an organic preservative compound used in natural cosmetics to ensure they stay free of any microbes.
Dehydroacetic acid is an organic acid found in nature in the flowers of the solandra species. Benzyl alcohol is a constituent found in many pure essential oils, and also in fruits and teas. Together they form an effective preservative that is ECOCERT approved and is recognised as a safe preservation method.
Why silicone-free?
Silicones are bioaccumulative. Once you rinse your skin and it goes down the drain, it can contribute to the buildup of pollution in oceans and waterways and may not break down for hundreds of years.
✔️ Organic ingredients
✔️ Free from silicones
✔️ Free from synthetic fragrances
✔️ Free from artificial colours
✔️ Free from phthalates and parabens
✔️ GMP manufactured
✔️ New Zealand made
✔️ Recyclable packaging
✔️ Not tested on animals
Directions: Apply to affected area as required. Use it to moisturise and condition dry, chafed skin. Apply to minor cuts, grazes, burns and insect bites to aid natural healing. No known side effects when used as directed. If symptoms persist, consult a healthcare professional.

Colloidal Silver is well-known to support the immune system and to help fight infections with its antimicrobial properties.
But it may also be the best all-natural, environmentally-friendly household disinfectant you can use for the safety, health and wellbeing of your entire family.
With its antibacterial, anti-fungal and antiviral properties, there are plenty of ways Colloidal Silver can be used to keep your home infection-free.
When Colloidal Silver encounters a virus, fungus, bacterium or any other single celled pathogen, it disables its oxygen metabolism enzyme. This effectively suffocates any bacteria, virus or fungus-producing cell, and they are unable to replicate.
A quick spray or wipe with Colloidal Silver is all you need to keep germs at bay. As it’s 100% natural, it doesn’t contain alcohol or any other chemicals, so it won’t dry out your skin, or leave any unwanted residue behind.
See below for ideas on how to use it around the home:
In the kitchen
Kitchen cloths and sponges can harbour all sorts of bacteria. Sanitise them regularly by lightly spraying with Colloidal Silver and then allow to dry.
Lightly spray chopping boards after washing and allow them to air dry to help prevent bacterial contamination.
Using a clean cloth and Colloidal Silver liquid, wipe out kitchen bins to prevent mould, decay and odours.
Surfaces around the home
Wipe down or spray all daily contact points in your home like door knobs and handles, cupboards and drawers.
Use it on car interiors; the steering wheel, gear stick and dashboard.
Colloidal Silver for pets
Mix a little Colloidal Silver in your pet’s drinking water to help protect against infections. Colloidal Silver can also eliminate most pet odours from your soft furnishings without damaging or staining them. Some furnishings, especially deep carpets, may need repeated applications.
In the bathroom
Spray it on toothbrushes, hairbrushes and combs to safely sterilise them. Using a clean cloth and Colloidal Silver liquid, wipe down the toilet seat. Don’t forget the handle or flushing mechanism as well as the door knob. Spray the toilet brush and plunger and allow it to air dry.
Mould on walls and ceilings
Mould can be a common and potentially dangerous problem in New Zealand homes. Lightly spray Colloidal Silver on to the walls and ceilings in your bathroom and other affected rooms to dramatically reduce the growth of mould and mildew.
Get right into the corners and seams where the walls and ceiling meet. Make sure you ventilate these areas to allow the Colloidal Silver to dry. Repeat weekly where necessary.
Children’s toys
Stuffed toys can be difficult to wash. Spraying children’s toys daily will help decrease the spread of germs. Simply spray the item, then allow to air dry.
Fruits, veggies and plants
Spraying Colloidal Silver on fruits and vegetables can delay mould growth and keep them fresher for longer.
Spray indoor plants to help prevent the growth of parasites, fungi, and to help stop most plant diseases.
Try spraying it on cut flowers to help them last longer.
Out shopping or when travelling
When shopping or travelling, take a spray bottle to quickly and easily disinfect things like shopping trolleys, surfaces in hotel rooms, and on planes.
Face masks
‘Maskne’ is a term for the acne flare-ups and skin irritation you can get from wearing a mask constantly. Bacteria can build up under a mask, which can lead to clogged pores, redness, and other skin conditions. You can alleviate this by staying hydrated, wearing a little less makeup, and washing your face regularly using a gentle cleanser.
If you wear a fabric mask, avoid synthetic fabrics, such as nylon or rayon, and wash it every day in hot soapy water. Allow to dry and then spray it with Colloidal Silver, as well as spraying a little on your face to avoid bacterial build-up. You can also spray it inside disposable masks for an extra layer of antibacterial protection.
Personal items
Spray it on watch bands to kill bacteria and avoid unpleasant odours. Try it on toothbrushes, hairbrushes and combs to safely sterilise. Spray Colloidal Silver in your shoes and between toes to help prevent skin itch, athlete’s foot and fungi.
Using a clean cloth and Colloidal Silver liquid, wipe down your mobile phone, headphones, reading glasses and remotes, that often harbour plenty of bacteria.

Ionic Colloidal Silver is very fine particles of 99.9% pure ionic silver suspended in purified water. It supports the immune system when the body is under attack and micro organisms cannot build up resistance to it.
Quite simply, silver interrupts the bacteria cell’s ability to form the chemical bonds essential to its survival.
It is often used as a natural alternative to antibiotics, as it has antimicrobial properties, which means it’s antibacterial, antifungal and antiviral. Colloidal silver has proven effective in killing many stubborn bacterial infections (including cold viruses) without the side effects of a pharmaceutical antibiotic.
Your immune system’s best friend
Colloidal Silver is suitable for the entire family, including pets, and there are no known interactions or side effects if taken as directed. Silver is a naturally occurring trace mineral found in our bodies and does not interact with any medication. It has been proven to promote the growth of new cells, enabling wounds to heal faster. Unlike other metals with antimicrobial properties, it is non-toxic.
Batch verified
Manufactured to less than or equal to 10ppm (parts per million). Medsafe New Zealand requirements stipulate that Colloidal Silver liquid products contain a silver concentration of 10ppm or below. Skybright independently tests every batch to ensure our Ionic Colloidal Silver meets this requirement.
Antimicrobial properties
Ionic Colloidal Silver supports the immune system when the body is under attack. Silver has antimicrobial properties that work by disabling the specific enzyme that many forms of bacteria, viruses and fungi use for their own oxygen metabolism.
Colloidal Silver FAQ’s
If you Google Colloidal Silver you’ll eventually come across references to Argyria – or ‘turning blue’. There are still concerns out there that taking Colloidal Silver will turn your skin blue or even grey. However, there hasn’t been a single report of Argyria from the use of 10ppm Colloidal Silver. Ever.
This discolouration of the skin can be caused by ingesting silver nitrates – not from properly prepared Colloidal Silver. Our Colloidal Silver is manufactured in a GMP facility here in Hawke’s Bay to ≤10ppm. We then test every batch with an independent laboratory to make sure it meets our strict quality standards, and adheres to Medsafe guidelines.
‘Ionic’ means the silver is in the form of single silver ions (ie: very tiny, positively charged particles). Ionic Colloidal Silver is most effective because it’s positively charged.
When body cells are infected they become negatively charged – positive Colloidal Silver is attracted to these negative cells, allowing the silver ions to go straight to the source of infection.
This does two things: Because the ionic particles are positively charged they repel each other and stay in suspension in the solution (like a magnet where like poles repel and opposite poles attract).
When body cells are infected they become negatively charged – positive colloidal silver is attracted to these negative cells, allowing the silver ions to go straight to the source of infection.
Some manufacturers make silver without the positive charge i.e. non ionic metallic silver and this is about 1000 times less effective than Skybright’s positively charged Ionic Colloidal Silver.
‘Colloidal’ means these particles are suspended in a liquid.
‘Parts Per Million’ (PPM) is a measure of the total amount, or weight, of silver – it is not a measure of its strength or effectiveness. This can be a confusing term as it has nothing to do with the number or size of silver particles or ions.
By passing electrical current across silver electrodes in pharmaceutical grade water to create microscopic silver ions.
Our silver particles are measured in ‘nanometres’ (nm), more specifically they are in the range of 1-5nm. The particle size is very important – the smaller the particles, the higher quality Ionic Colloidal Silver.
Skybright Ionic Colloidal Silver is manufactured with a small particle size, is positively charged and will be within the maximum efficacy range of ≤10 ppm. Colloidal Silver is very effective at this strength in providing support for the body’s immune system.

People take Apple Cider Vinegar for many reasons. These can include general wellbeing, immune support, type 2 diabetes, digestive complaints, or for joint health and mobility. It’s a good source of minerals, and can even help with minor burns and wounds (when applied topically) and maintain a healthy hair and scalp.
Apple Cider Vinegar contains acetic acid, which promotes digestive health with gut-friendly bacteria and pectin. Pectin has been shown to help maintain healthy cholesterol levels.
It also has cleansing properties that can help maintain healthy blood sugar levels and balance your body’s pH, resulting in increased energy.
Studies have shown it can help improve insulin sensitivity during a high-carb meal and lowers blood glucose and insulin responses.
High blood sugar levels are thought to be a major cause of ageing and various chronic diseases. The best way to regulate blood sugar levels is to avoid refined carbs and sugar, but Organic Apple Cider Vinegar may have a beneficial effect. It may contribute to weight loss by lowering blood sugar and reducing insulin levels.
Organic Apple Cider Vinegar can help keep the skin clear and the system toned and regular. It can also assist with the body’s acid/alkaline balance to relieve conditions such as gout, rheumatism, arthritis and other joint discomfort.
It contains enzymes and proteins and is a good source of many minerals including: potassium, sodium, magnesium, calcium, sulphur, iron and silicon.
Athletes often drink diluted Organic Apple Cider Vinegar before they carb-load the night prior to competition, as the acetic acid can help your muscles turn carbs into energy to fuel intense exercise. ACV provides the gut with a healthy mix of electrolytes that can help in preventing muscle and gastrointestinal cramping.
Itʻs totally up to you. We recommend you start with a teaspoon (5ml) and over the course of a few days build your way up to a tablespoon (15ml), mixed into a glass of water.
Fill a large glass of water and add a tablespoon (15ml) of ACV first thing in the morning, before meals, or in the evening.
The time-honoured recipe for general wellbeing is a daily tonic of 15-20ml of Organic Apple Cider Vinegar in a large glass of water, and take first thing in the morning. Others believe that two teaspoons of vinegar in a glass of water should be taken before each meal (up to three times a day) to promote digestive function.
We don’t recommend you take it straight – as Apple Cider Vinegar is very acidic, it can be harsh on your oesophagus if you take it as a shot. You get all the same benefits when diluting it in a glass of water, and it is just as effective.
The difference with Skybright Organic Apple Cider Vinegar is that it is aged for 12 months. This ageing process gives it a distinctly smoother taste. The smooth taste certainly helps when taking it first thing in the morning! If you’ve ever sampled Apple Cider Vinegar before that isn’t aged you’ll certainly notice the difference.
If you’re struggling with the taste, try adding a squeeze of lemon juice or a teaspoon of (mānuka) honey with it. The lemon is a good source of vitamin C and the acid can help speed up digestion and reduce inflammation. Mānuka honey has additional antibacterial properties too, for an even bigger immune boost.
Try adding a tablespoon of Organic Apple Cider Vinegar to a cup of green tea for added antioxidants, and add sliced lemon and fresh ginger. Delicious and nutritious.
‘The mother’ is the cloudy sediment within the bottle that contains all the naturally occurring proteins, amino acids, antioxidants, enzymes and healthy bacteria that helps your body break down food and fully utilise the nutrients. Studies have shown that good gut bacteria can positively impact one’s metabolism, mood, and brain function.
The mother is the most beneficial component of the vinegar, and contains all the goodness for your gut. It is similar to a scoby that you would find in kombucha.
There are many options these days to get your daily dose of Organic Apple Cider Vinegar. These include gummies, capsules and tablets. While they can be convenient, and easy to take, they often contain sugars and other fillers that aren’t great for your digestive system. With tablets and capsules, your body might not be able to break them down efficiently.
As our Organic Apple Cider Vinegar is in liquid form, it is 100% bioavailable, meaning it is quickly absorbed and your body can digest and utilise the many nutrients, enzymes, good bacteria and proteins that it contains.
You could store it in the refrigerator but this is not necessary, as it’s fermented it will essentially last for years.
It’s best to keep it in the cupboard, away from direct sunlight. Give it a good shake before using each day to disperse the mother.
While Organic Apple Cider Vinegar is safe when used as directed, it’s always best to check with a health professional before taking a supplement, especially when on medication.
Organic Apple Cider Vinegar is essentially a fermented food, made from purified water and New Zealand organic apples. However, if you’re currently taking blood-sugar-lowering medications, talk with your doctor before taking ACV.
Vinegar is of course highly acidic, and taking straight could weaken the enamel on your teeth. That’s why it’s best to dilute the Organic Apple Cider Vinegar into plenty of water, drink it through a reusable straw and rinse your mouth with water afterwards. Many dentists agree it is perfectly fine to drink, and won’t damage your teeth, especially when compared to the myriad of sugary drinks available.
Yes. Once you’re finished, it can be repurposed as a water bottle or recycled.
If you take a tablespoon (15ml) in a glass of water each day, a 750ml bottle will last you approximately 50 days. That works out to be just 25 cents a day to help improve your health and wellbeing.
You should notice the difference in as little as a few days. Once you get into a good routine after a number of weeks you might start to notice all sorts of health benefits.
The product has a shelf life of two years stamped onto the bottle, but as it is fermented it will last for many years.
Our Organic Apple Cider Vinegar is made from sun-ripened New Zealand apples. They are BioGro Certified organic, and often a mix of different organic varieties, depending on seasons and growing conditions.
The colour of the vinegar often varies from batch to batch, as it is a natural product. This variation can depend on the mix of apples used and the length of the ageing process.
Prebiotics are indigestible carbohydrates that nourish good gut bacteria, helping support the health of your digestive system by boosting growth of good bacterial colonies.
Both prebiotics and probiotics help support the good bacteria in your gut that are associated with improved health and well being. Raw, Organic Apple Cider Vinegar is a prebiotic. Prebiotics are a special form of dietary fibre that acts as a fertiliser, or food for probiotics, the good bacteria in your gut. A garden can be a helpful metaphor when understanding the difference between a prebiotic and a probiotic. You can add seeds—the probiotic bacteria—while the prebiotic fibre is the water and fertiliser that helps the seeds to grow and flourish.
There are no known side effects when using as directed. Itʻs also safe to take during pregnancy & breastfeeding. It’s all-natural, vegan-friendly, keto-friendly and gluten-free.
“Eat fermented foods, sleep a lot, fill up on fibre, and maintain a healthy weight. Your belly and your brain will thank you.”

When you hear the word iodine, you may think of the tablets used to disinfect water on camping trips or the yellow liquid used for disinfecting cuts and grazes when we were younger. Or you may just remember it from the periodic table in chemistry class.
Iodine is one of the most important life-sustaining elements. For more than 100 years, it has been known as the element that is necessary for thyroid hormone production. However, it is so much more than that.
Iodine is found in each and every one of the trillions of cells in the body, and responsible for the production of all the other hormones in the body.
It has strong anti-inflammatory effects by neutralising free radicals and is necessary for proper immune system function. Working together with other minerals like Selenium, it has many therapeutic benefits for a range of modern illnesses and diseases.
It is estimated by the World Health Organisation (WHO) that more than half of the world’s population live in an area of iodine deficiency, and that this has risen 400% in the last few decades due to soil depletion and an increase in environmental contaminants that have replaced it.
Our body does not make iodine, so we need to access it from the foods we eat. But if the nutrients are not in the soil to begin with, it cannot be in the food we eat, and this can lead to common deficiencies.
Iodine deficiency in New Zealand
Soil in coastal areas are naturally iodine-rich, as are the dairy products produced by the cows that graze there. Fresh produce such as fruits and vegetables that are grown in coastal areas are also rich in iodine.
This can be due to intensive farming, lack of crop rotation and the use of fertilisers. Coupled with changes to our diet, the reduced use of iodised salt in the household, the prevalence of processed foods, many New Zealanders are now lacking important nutrients such as iodine that are key to good health.
The WHO’s research has suggested deficiencies in both Australia and New Zealand are re-emerging, when they were previously thought to be iodine sufficient.
This research suggests that we may be consuming less than 60% of what is recommended. While we all need iodine, it is especially important for women who are trying to fall pregnant, are currently pregnant or who are breastfeeding, as the body demands more during this time due to increased thyroid hormone production, and the requirements of the developing baby.
Properly evaluating and treating iodine deficiency will help people support thyroid health and immune system function, increase their energy levels, and help improve general health and wellbeing. This can be achieved by some simple changes to their diet or daily supplementation in consultation with their health practitioner. It can be as little as a couple of drops of potassium iodide in a glass of water each day to get you feeling better, and help you avoid some of the common but serious health problems we are seeing today in New Zealand and around the world.
The best results are seen with a holistic approach, and increasing the intake of important vitamins, minerals and electrolytes through a wholefood diet.
The hungry thyroid
The thyroid is often referred to as a ‘hungry’ part of the body, in reference to its high nutritional demands.
This butterfly-shaped endocrine gland surrounds the windpipe and is important for metabolism, regulating digestion and your heart rate. It facilitates energy production and mental agility. The thyroid also helps with fat burning too, by determining how quickly and efficiently kilojoules are burned up, and it assists in the breakdown of proteins. Thyroid function also assists the suppleness and strength of our hair, skin and nails.
Iodine is an essential ingredient in all thyroid hormones, including T4 (thyroxine) and T3 (triiodothyronine). It is important to maintain sufficient amounts of iodine, and they are required to be synthesised in adequate amounts. In a low thyroid state, known as hypothyroidism, the thyroid gland can’t make enough thyroid hormone to keep the body running normally. The metabolic state is therefore reduced which can lead to weight gain.
When the thyroid gland is releasing excess amounts of thyroid hormone, it is known as hyperthyroidism, which is an overactive or elevated metabolic state which can result in fatigue, irregular heartbeat, unexplained weight loss and brain fog.
When you have an adequate intake of iodine, your body contains 20-50g, and 75% of that amount is stored in the thyroid. However large amounts are also stored in other parts of the body, including the salivary glands, the breasts, ovaries, and the brain. In the brain it concentrates in the substantia nigra, the part of the brain that is associated with Parkinson’s disease.
The lack of iodine causes the gland to expand in an attempt to extract as much iodine in the bloodstream as possible. If your iodine intake is low, this will be reflected in low levels of thyroid hormone. You may then experience fatigue, dry skin, constipation, systemic inflammation, a hoarse voice, delayed reflexes and some cognitive impairment.
It is best to consult your doctor or health professional should you identify any of these symptoms. Anybody taking thyroid medication should always discuss their condition with a health professional before taking supplementary iodine.
The role of selenium
Selenium, another important mineral and antioxidant, plays a significant role in regulating thyroid function and iodine metabolism. The thyroid contains more selenium by weight than any other organ in the body.
Selenium is a required component for the production of the enzyme glutathione peroxidase, which protects the body from damage with antioxidant capabilities.
Without this enzyme, the thyroid gland is susceptible to damage from oxidants, there would be no activation of thyroid hormone without selenium.
The need for iodine before pregnancy
The consequences of iodine deficiency are most serious for women who are trying to fall pregnant, who are currently pregnant or are breastfeeding.
Thyroid hormones balance the function and development of the body’s major organs and influence the progress of the developing baby.
Research has shown that a lack of iodine can cause fetal and neonatal mental disabilities and growth problems, along with speech and hearing issues. Cognitive function and neurological development can be impaired when iodine levels are low.
It is recommended that women take iodine supplements from the point of planned pregnancy and through the full duration of pregnancy as well as breastfeeding. Avoid kelp or seaweed supplements as they may be contaminated with heavy metals such as mercury. Multi-vitamin, multi-mineral and pre-natal supplements may or may not contain enough iodine, so it’s best to check.
Women with pre-existing thyroid conditions should always check with their health professional before taking a supplement.
How do I know if I’m deficient?
Under most states of iodine sufficiency, approximately 90% of dietary iodine eventually is excreted in the urine, with exception being the lactating female due to iodine excretion in the breast milk. Because of this, urine is the best biological fluid to use for assessment of deficiency.
If you are concerned there may be deficiency, you could undertake an iodine-loading test, otherwise known as a urinary iodine concentration (UIC) where you take a prescribed dose of iodine, then collect 24 hours of urine to undergo analysis with a health professional.
The principle of this test is that if you’re iodine sufficient, most of the dose will be excreted, and if there is a deficiency present, it will be instead be absorbed by the body.
Can I get enough iodine from salt?
Iodised table salt was implemented in many regions and countries around the world when iodine deficiency was recognised. In New Zealand in the 1920’s, the government allowed manufacturers to voluntarily add iodine to table salt. This was mainly to safeguard against thyroid enlargement (goitre) and the severe mental retardation of cretinism, although the incidence of these conditions was very rare in New Zealand.
In recent decades we have seen people consume less salt due to health concerns, while some avoid salt entirely. Salt used in processed foods is often non-iodised to save on costs, so is not a source of iodine despite the sodium content.
In recent times we are seeing a prevalence of sea salt, or kosher salt, promoted as a healthier alternative. However, sea salt is a poor source of iodine, and we should look for unrefined, unprocessed sea salt, with some products now enriched with New Zealand sea kelp. The iodine in salt is not very bioavailable in our bodies, it is better absorbed through liquid and food sources.
Other sources of dietary iodine
It can be difficult to identify sources and the quantity of iodine in most foods. However, it is naturally present in seawater, so therefore seafood is a good source, especially seaweed, shellfish and saltwater fish. It’s also naturally present in soil, and found in eggs and dairy, including yoghurt, cow’s milk, ice cream and cheese.
If you don’t have access to shellfish or other seafood, or if the soil is deficient due to intensive farming, you’ll need to access it from other sources.
Iodine levels in milk can vary according to the soils in which the animals have grazed and factors such as the groundwater used in irrigation, fertilisers used and the feed for the livestock. Interestingly, organic milk is estimated to contain roughly 30-40% less iodine than conventional milk, owing to alternative processing methods.
That said, in 2009, Iodine fortification of bread became mandatory with the exception of organic bread, non-yeast-leavened bread and bread mixes. When salt was iodised in the 20th century, this significantly improved the iodine levels within the New Zealand population, but recently deficiencies have again become apparent, hence the need for the fortification of foods.
Iodine dosage guidelines
There is no single dose of iodine that is effective for everyone. The best approach is working with a health professional that is knowledgeable about iodine.
If you eat seafood and other iodine-rich foods, use iodised salt, take a multi-vitamin or mineral supplement, you may be able to obtain adequate levels.
Recommended daily allowances range from 100-250mcg a day, with the exception of pregnant or breastfeeding women, who may require more than 300mcg per day due to increased hormone production in early pregnancy, increased urinary iodine excretion, and the transfer of iodine to the fetus or the nursing infant when feeding.
Some leading iodine experts suggest significantly larger daily doses, even up to 12mg. In Japan, the average daily intake is 12-13 milligrams due to increased consumption of seaweed and other seafood.
Summary
Iodine is one the most basic elements of all life on earth, it is present in the ocean, marine life and in every one of the trillions of cells in our body. The role it plays in our everyday wellbeing cannot be overstated. As our bodies can’t produce iodine, there are simple steps we can take to make sure we can rebalance and replenish our mineral levels, and avoid deficiencies.
