Vitamin D has become a well-known supplement that plays many roles in human health – and about one in five Canadians are not getting enough*!
Vitamin D is a fat-soluble substance made up of a group of steroids. It is unique in that it is both a micronutrient we eat and a hormone generated by our bodies. Vitamin D is required for the healthy development and maintenance of bones and teeth, as well as mineral absorption, and is vital in maintaining and supporting the immune system, not to mention many other biological functions in the body.
In fact, we have seen vitamin D receive more attention in the media over the last few years for its association with immune system health. As people seek to optimize their immunity as much as possible, researchers have examined the role of vitamin D in modulating the innate and adaptive immune responses, with promising results!
We get vitamin D three ways:
- sun exposure
Food sources of vitamin D include fatty fish (salmon, trout, mackerel), sun-exposed mushrooms, beef liver, and egg yolks.
Other foods are fortified with vitamin D, including milk, margarine, plant-based beverages, orange juice, and some yogurts and cheese (often made with vitamin D fortified milk).
Vitamin D is unique in that our bodies can generate it. It is nicknamed “the sunshine vitamin” because, when human skin is exposed to sunlight (UVB ultraviolet light), a compound known as 7-dehydrocholesterol is converted into vitamin D3 in the epidermis (the outermost layer of the skin).
FACT: There are 2 forms of vitamin D: D2 and D3. D3 (cholecalciferol)is the form generated by the skin and is primarily found in animal foods, such as fish, liver, and eggs. It is the most effective and stable for supplementation. D2 (ergocalciferol) is mostly found in mushrooms and fortified foods, like some cereals, as it is less expensive to source.
Despite our ability to get vitamin D from both diet and sun exposure, it’s not as easy as it may seem, and some health authorities have described its deficiency as a world-wide epidemic.
A deficiency of vitamin D has been linked to bone health issues, susceptibility to illness, general symptoms like chronic pain and tiredness, a tendency to frequent infections, and depression – and it’s important to get vitamin D every day!
While vitamin D is found in some foods, most diets don’t contain many natural sources, or aren’t eaten in quantities necessary to make them an adequate source.
As for sun exposure, many factors influence getting enough for adequate generation of vitamin D:
- seasonal daylight hours
- time of day
- cloud cover and smog (air pollution)
- sunscreen use
- limited outdoor time
- amount of skin exposed to sunlight
- age (decreased ability to generate vitamin D with age)
- colour of skin (darker skin absorbs fewer UV rays)
Plus, long, dark Canadian winters make the population more susceptible to D deficiency due to a lack of sunlight. Given that winter is the peak of cold & flu season, getting enough is important to support healthy immunity!
Supplementation ensures that you are reaping the valuable health benefits of this essential nutrient – but some vitamin D supplements offer greater quality and absorption than others.
Vitamin D3-for-All offers a simple way to get a daily dose of D. Just one drop a day ensures you’re getting enough of this vital nutrient in the most effective D3 form that can be hard to get from dietary sources.
Liquid drops ensure fast absorption and an easy-to-take format that’s suitable for the whole family. PLUS, as vitamin D is a fat-soluble nutrient – its absorption is further enhanced by a base of MCTs from coconut oil along with antioxidant-rich natural rosemary extract for the highest potency and stability.
Vitamin D3-for-All helps to round out a healthy diet to ensure your body is getting what it needs to be healthy – and stay that way!
