What is Colloidal Silver?

Woman holding her arms out asking the question "What is Colloidal Silver?"

What is Colloidal Silver?

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.

Colloidal Silver is suitable for the entire family. A must-have in your bathroom cabinet.

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.

“This is my go-to product for use with the whole family including the animals. I’m certain it has saved us a number of trips to the doctor with early application. Great to have around the house, in the first aid kit and in your handbag.”

Colloidal Silver FAQ’s

Have a question for us?

We’d be happy to answer any questions you have regarding Colloidal Silver.

Send us an email, phone us on 0800 200 707 or message us on Instagram, Facebook or Twitter.

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 10 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.

Colloidal Silver can be used in conjunction with other medications and supplements. It is extremely safe when used as directed, and suitable for all the family, including pets.

When feeling unwell, take 5ml of Colloidal Silver liquid three times a day for five days.

Applying Colloidal Silver to your skin

Colloidal Silver can be applied topically to help prevent infection or to fight an existing condition. It is suitable for use on broken skin and can be used as an antibacterial or antifungal application for wounds, cuts, grazes, insect bites, minor burns and fungal infections. As it’s non-stinging, it’s great for use on kids to prevent infection on any cuts or wounds and aids fast healing.

Spray onto the affected area, allow to dry, then apply Skybright Colloidal Silver Cream, with the the additional antimicrobial benefits of mānuka oil and mānuka honey. Or apply Skybright Colloidal Silver Aloe Vera Gel, which is regenerative, soothing, cooling and calming for the skin and particularly effective on minor burns and sunburn. 

Spray Colloidal Silver into the mouth to soothe a sore throat.

Colloidal Silver Spray for sore throats

Spray Colloidal Silver into the mouth several times a day for sore throats, laryngitis, dry coughs, mouth ulcers, gum infections or after dental work. Alternatively, use the liquid like a mouthwash and gargle – it can be safely swallowed afterwards.

Swedish Bitters: A herbal tonic

Young woman stretching outdoors. Better digestive health with Swedish Bitters.

Swedish Bitters for digestive health

Swedish Bitters is a 400 year-old European herbal formula made popular through the well-known Austrian herbalist Maria Treben in her book “Health through God’s Pharmacy”. It is well proven over the years to be an outstanding digestive, liver and gallbladder tonic and is capable of supporting a huge range of body systems.

The bitter taste has a very important part to play in the effectiveness of the formulation. The liver, the keeper of balance in the body, is stimulated by the bitters in Swedish Bitters and will then produce fluids required for proper and complete digestion and drive toxins out of your system. 

It is very important to cleanse your body of toxins and unwanted substances. This helps to revitalise the entire circulatory system, which may help to regulate blood sugar levels, improve blood pressure and strengthen the immune system.

Why the bitter taste?

Bitters are an important class of botanicals that help support efficient digestive, assimilative, and eliminative functions. The primary function of Swedish Bitters is to help with digestive complaints like bloating, flatulence, sluggish digestion and constipation. Bitters stimulate the flow of bile from the liver, which in turn stimulates intestinal peristalsis and promotes nutrient absorption. By enhancing digestion, Swedish Bitters are a great help in cases of bloating, flatulence and gas.

“These bitter substances have almost been completely eliminated from the modern diet. This has caused some disturbance with our digestive system.”

Austrian herbalist Maria Treben in her book “Health Through God’s Pharmacy

Bitters have the ability to improve kidney and liver function, reduce bloating and improve metabolism. They can encourage toxin elimination, restore natural acid balance in the stomach, stimulate circulation and act as a gentle laxative.

Deer Antler Velvet

Skybright Deer Antler Velvet to strengthen, protect and restore

Deer Antler Velvet to strengthen, protect and restore 

Deer Antler Velvet comes from the antlers of male deer, and is the name  given to the softer new growth that is covered in velvety hair. It’s been used in Chinese medicine for over two thousand years for its health giving properties. 

It is rich in amino acids, essential fatty acids, collagen, glucosamine, chondroitin, omega 3 and omega 6, and many other important vitamins and minerals. These work together to help strengthen the immune system, support healthy blood pressure, boost energy levels, aid joint mobility, promote recovery, reduce inflammation and improve cardiovascular health and function.

Deer antlers can grow up to 2cm per day.
Deer antlers can grow up to 2cm per day.

A renewable resource
The antlers regenerate swiftly every spring (up to 2cm per day), and because of this quick growth, they are a rich source of essential vitamins, minerals and nutrients. The antlers are removed before they harden into bone.

Made in New Zealand
This process is done by trained and accredited farmers and veterinarians here in New Zealand, who ensure minimum discomfort to the deer. The velvet is then freeze dried to preserve the nutrients and ground to a fine powder.

Traditional uses
The uses of Deer Antler Velvet are many and varied, but they tend to fall into the general categories of support for: body strengthening, blood cell production, the immune system, healthy joint function and cardiovascular health.

Our Deer Antler Velvet capsules are an authentic 100% natural, sustainable New Zealand product of the finest quality. 

Immune system support
Deer Antler Velvet has the ability to strengthen the body’s natural immune system, counter the effects of stress, and promote rapid recovery from illness. It is also used at the onset of winter to ward off infections.

Sore joints?
Deer Antler Velvet is a natural source of anti-inflammatories such as chondroitin and glucosamine sulphate. It helps inhibit the breakdown of cartilage, and supports healthy joint structure and function.

Recover faster
Widely used by athletes to support improved sports performance, Deer Antler Velvet is an excellent promoter of recovery after physical activity and aids injury recovery time along with also being an injury preventive.

“I’m 68 years young and have been taking this product for four years and I have not noticed any reduction in suppleness in my joints”

— John

Blood circulation
Research has shown that Deer Antler Velvet supports the oxygen carrying capacity of blood, facilitating healthy blood pressure and circulation. Blood pressure reduction is due to its ability to increase dilation of the peripheral blood vessels.

Back into balance
Men and women of all ages can benefit because it supports the body’s ability to adapt to and resist stress, diseases, degeneration and toxins. Deer Antler Velvet helps bring the body’s systems back into balance.

Are there any concerns?
As with all dietary supplements, you should not exceed the recommended daily dose and should consult your healthcare professional if you are on prescription medication.

A to Zinc: A handy guide

A to Zinc

Acne: Zinc is an important component for healthy skin, and in particular for sufferers of acne. It can control the production of oil in the skin and help balance some of the hormones that can lead to acne. Many skin disorders can be attributed to insufficient zinc.

Bioavailability: The bioavailability of zinc from grains and plant foods is lower than that from animal- based foods such as lean red meat and poultry, although many grain and plant-based foods are still good sources of zinc.

Common Cold: Much research has been done around zinc and its capacity to combat the common cold. Although studies examining zinc treatment on cold symptoms has shown varied results over years, it appears to be beneficial under certain circumstances. The Cochrane Report concluded that taking it within 24 hours of developing symptoms and has been shown to reduce the severity and duration of cold symptoms in healthy people by up to a third. It does this by directly inhibiting the rhinovirus binding and replicating and suppressing inflammation.

Depression: Virtually every enzyme reaction in the brain involves zinc, and low levels have been linked to anxiety and depression.

Eyesight: Research has suggested that zinc and antioxidants may delay the progression of age- related macular degeneration and vision loss, possibly by preventing cellular damage in the retina.

Food sources: Lean red meat is an excellent dietary source, and it is also highly bioavailable, meaning your body can absorb it much more readily. Poultry, nuts, seeds, and lentils are other good sources. Green leafy vegetables and fruits contain modest amounts of zinc.

Grains: Wholegrain breads, cereals and other grains contain zinc, but these foods also contain phytates, which can bind zinc and therefore inhibit its absorption. While these plant-based options are good dietary sources, the bioavailability is often lower than animal-based products.

Hair loss: In severe cases zinc deficiency can cause hair loss and a dry flaky scalp.

Immune system: Zinc is needed for the proper functioning of the immune system, and enables protein synthesis and cell growth.

Job: Zinc is often seen as the gatekeeper for your immune system, to ward off bacterial and viral infections like the common cold.

Kids: Zinc supports normal growth and physical development during pregnancy, and this continues through childhood and adolescence.

Low zinc content in our soils: Plants, like our bodies, cannot make minerals. They instead extract them from the soil. Like many other mineral and trace elements, if they are lacking in the soil they will be lacking in the plants we eat or the animals that are grazing the fields and providing our much-need protein. If certain crops aren’t rotated, it can seriously deplete the soils of these minerals, leading to deficiencies in our diet.

Magnesium: Both zinc and magnesium help protect the brain and the eyes from excitotoxin additives that are common in foods today. In New Zealand, deficiency of both of these minerals is common due to soil depletion.

Nutrients: As well as being involved in hundreds of processes within the body, zinc helps us absorb and utilise nutrients from our food.

Oysters: Oysters contain more zinc per serving than any other food.

RDI for zinc is higher for pregnant and lactating women.

Pregnant women: Pregnant and breastfeeding mothers may require bigger intakes, as there are high foetal requirements for zinc, and lactation can also rapidly deplete mineral stores. For these reasons, the RDI for zinc is higher for pregnant and lactating women, and supplementation is often recommended.

Quote: “Just about all skin disorders improve if you build up your zinc stores.” Dr Robert Atkins

RDI (Recommended Daily Intakes): Common RDIs for zinc are as low as 5mg for a child, 7mg for a teenage girl, 13mg for a teenage boy. For adult woman it is 8mg, increasing to 12 mg when breastfeeding or pregnant, and 14mg for adult males.

Stress: There is evidence that zinc levels decrease following physical stress or injury. It is one of the few minerals lost in the urine following acute or chronic physical stress.

Taste test: There is a simple test you can take to measure your zinc status, which can often be provided by your local health shop. It involves taking a tiny amount of zinc sulphate, dissolving it in water and then tasting as little as a spoonful. This test works because zinc is required for your taste buds to function. If you notice a bitter, astringent taste you are not deficient. If this bitter taste is delayed by more than a few seconds, you need more zinc in your diet. If there is a much longer delay or if you don’t notice the bitterness or it tastes like water, you may have a deficiency and will need to restore your zinc levels.

Ultimate nutrient: Zinc is responsible for hundreds of processes within our brain and our body, and is one of the most important minerals for our health throughout our life. There are more roles in the body for zinc than any other nutrient.

Vegetarians often require as much as 50% more of the RDI for zinc.

Vegetarians: Vegetarians often require as much as 50% more of the RDI for zinc than non-vegetarians. Zinc can be sourced from whole-grain breads, cereals, nuts, seeds, beans and legumes, but these foods also contain phytates, which can bind zinc and therefore inhibit its absorption. While these plant-based options are good dietary sources, the bioavailability is often lower than animal- based products.

Vitamin C: With the help of vitamin C, zinc has been used in research into improving age-related macular degeneration (AMD). After an average follow-up period, supplementation with antioxidants plus zinc (but not antioxidants alone) significantly reduced the risk of developing advanced AMD and reduced visual acuity loss.

Wound healing: Zinc is critical for wound healing, whether it is a small cut, or helping the skin recover from surgical procedures. It also helps prevent scar formation.

EXcessive zinc: A over-large intake of zinc may result in side effects with symptoms ranging from mild to severe. Intake of 50 to 150 milligrams per day of supplemental zinc may cause minor intestinal distress occurring within three to 10 hours after ingestion. Single doses of 225 to 450 milligrams of zinc usually cause nausea and induce vomiting.

Yellow fungus growth on toenails: Many skin disorders are related to insufficient zinc, including abdominal stretchmarks after childbirth, split fingernails with white specks, as well as yellow toenails and/or fungus growth.

Zinc: There are more roles for zinc than any other nutrient. It is one of the most important elements for our health yet one of the most deficient in our diet, especially here in New Zealand. This is due to the quality of our soils and the impact of the foods we eat, and the water we drink.

Why is Zinc essential?

Why is Zinc essential?

There are more roles for zinc than any other nutrient. It is one of the most important elements for our health, yet one of the most deficient in our diet, especially here in New Zealand.

The chronic lack of zinc in Aotearoa is due to the quality of our soils and the impact of the foods we eat, and the water we drink.

Here’s an overview of the critical roles this mineral plays in our bodies. Also see our handy guide: A to Zinc.

Zinc’s Role

Zinc is involved in hundreds of processes within the body, and it helps us absorb and utilise nutrients from our food.

It plays a role in immune function, helping repel and overcome bacterial and viral infections like the common cold. It assists with growth development, protein and DNA synthesis, and is effective in wound healing.

Zinc is essential for the brain and neurological function as well as the maintenance of vision, taste and smell. It nourishes the scalp and helps maintain strong and healthy gums, hair, skin and nails. It can help avoid hair loss, which can be a symptom that you may be deficient. Zinc can control the production of oil in the skin and help balance some of the hormones that can lead to acne. Many skin disorders can be attributed to insufficient zinc.

Zinc is important to our health and wellbeing throughout our life. It supports normal growth and physical development during pregnancy, and this support continues through childhood and adolescence.

There is almost no part of the body that zinc doesn’t benefit, either inside or out.

It is key to both male and female reproductive health and is vital as we grow older, as it helps maintain bone density and muscle bulk.

However, zinc can be harder to access through diet for both women and men as they age, as the body doesn’t have the ability to store minerals. New Zealand surveys have shown that 52% of middle-aged men aren’t getting enough zinc each day, and that figure increased to 90% for men aged over 70.

Zinc has been shown to reduce the severity and duration of cold symptoms.

Zinc and the Common Cold

Much research has been done around zinc and its capacity to combat the common cold. Although studies examining zinc treatment on cold symptoms have shown varied results over years, it appears to be beneficial under certain circumstances.

The Cochrane Report concluded that taking it within 24 hours of developing symptoms has been shown to reduce the severity and duration of cold symptoms in healthy people by up to a third. It does this by directly inhibiting the rhinovirus binding and replicating and suppressing inflammation.

More research is needed to determine the optimal dosage, formulation and duration of treatment before a recommendation for zinc in the treatment of the common cold can be made.

Some of us need zinc more than others.

Studies have shown that New Zealand men have lowered zinc status, especially as they age. Men require an RDI of 14mg just to prevent deficiency.

Several New Zealand studies have suggested that many adolescent girls aren’t getting enough zinc and this may be affecting their growth and development. This could be due to changing diets, less red meat and seafood being consumed, as well as the prevalence of processed foods, which are often refined and lacking minerals and other nutrients.

Pregnant and breastfeeding mothers also require bigger intakes, as there are high foetal requirements for zinc, and lactation can also rapidly deplete mineral stores. Breast milk provides enough zinc (RDI 2mg) for baby for the first six months, but zinc needs to be acquired from food sources as the child grows. Supplementation of zinc has been shown to improve the growth and development of some children who have exhibited a mineral deficiency.

Zinc has limited storage capacity with our body, so a deficiency can develop quickly if we’re not restoring and replenishing.

Diagnosing Deficiency

Blood tests are not a reliable method for detecting zinc deficiency as most of the zinc in our bodies is retained in our cells rather than in our blood. However, there is a simple test you can take to measure your zinc status, which can often be provided by your local health shop.

It involves taking a tiny amount of zinc sulphate, dissolving it in water and then tasting as little as a spoonful. This test works because zinc is required for your taste buds to function.

If you notice a bitter, astringent taste you are not deficient. If this bitter taste is delayed by more than a few seconds, you need more zinc in your diet. If there is a much longer delay or if you don’t notice the bitterness or it tastes like water, you may have a deficiency and will need to restore your zinc levels.

In this case, you may already be experiencing some common symptoms of a low zinc status such as frequent colds or infections, weak sense of smell and taste, hair loss, slow wound healing or skin disorders and inflammation.

You may be advised to supplement with zinc for a period and look to include more zinc-rich foods in your diet, such as lean red meat, dairy, seafood, poultry, or whole-grains, beans and legumes.

Getting Zinc into Your Daily Diet

The best source of zinc is rock oysters, which contain significantly more zinc than red meat and grains but are often not a regular part of our diet. Fats, which contain very little zinc, also tend to dilute zinc from the diet.

Lean red meat is an excellent dietary source, and it is also highly bioavailable, meaning your body can absorb it much more readily. Green leafy vegetables and fruits contain modest sources of zinc.

There is almost no part of the body that zinc doesn’t benefit, either inside or out.

Some animal-free options include whole-grain breads, cereals, nuts, seeds, beans and legumes, but these foods also contain phytates, which can bind zinc and therefore inhibit its absorption. While these plant-based options are good dietary sources, the bioavailability is often lower than animal- based products.

Vegetarians often require as much as 50% more of the RDI for zinc than non-vegetarians.

Note that techniques such as soaking beans and grains in water for several hours can reduce this binding of zinc by phytates and thus increase bioavailability.Vegetarians often require as much as 50% more of the RDI for zinc than non-vegetarians.

Studies from New Zealand nutrition surveys and overseas research suggest most of us are accessing only half of the daily zinc we require from our diet.

Zinc Deficiency Inhibits Absorption

Once you become zinc deficient, it can be very difficult to improve zinc levels purely through food alone, as your body’s absorption often depends on having enough zinc in the first place.

In addition, if you are recovering from an operation, have suffered emotional stress, or been over-exercising, your body will look to use all the available zinc on offer in an effort to heal. Zinc is one the few minerals lost rapidly in the urine after suffering acute psychological stress.

Gastrointestinal surgery and digestive disorders such as Crohn’s disease can decrease zinc absorption. Other illnesses associated with zinc deficiency include chronic liver disease, alcoholic cirrhosis, anorexia nervosa, chronic renal disease, diabetes, malignancy and sickle cell disease. Diarrhoea can also lead to excessive loss.

Supplementation may then be required to achieve good zinc status and you will then be able to maximise your zinc from food sources once again.

Summary

While we should be getting our important vitamins, minerals and other nutrients from the food we eat, there are often factors that prevent this from happening.

Soil depletion, the prevalence of processed food and bouts of illness can lead to mineral deficiencies that prevent the nutrients reaching the cells in our body and enabling the hundreds of processes that keep us healthy.

It is important to be aware of some simple things we can do to restore and replenish these minerals, to maintain optimal levels and supplement when needed to avoid larger health problems.
