Are you taking your vitamin D? Also known as the sunshine vitamin, vitamin D is responsible for hundreds of functions in the body. While this vitamin may appear easy to obtain from sun and diet alone, vitamin D deficiency runs rampant. This is especially true for those of us living in Canada or the US, but deficiency is possible even in dreamy tropical retreats, due to folks covering up more and using sunscreen.
The risks associated with excess vitamin D might be keeping you away from supplements, out of fear of what might go wrong! But vitamin D toxicity from excess supplementation only occurs when you consume 100 times more vitamin D than the recommended daily allowance for many months at a time. In other words, the benefits of vitamin D supplements far outweigh the risks.

Vitamin D: The difference between D and D3
But first, let’s get a few things straight. Should you supplement with vitamin D or D3? Vitamin D is synthesized by the body from sun exposure. When it comes to diet and supplement sources of vitamin D, the most common you’ll encounter are vitamin D2 and vitamin D3. Regular vitamin D supplements were, until recently, made up of what we now call vitamin D2.
Vitamin D2 in supplement form is made by exposing ergosterol, a sterol extracted from yeast or fungi, to ultraviolet light. Ergosterol from yeast and fungi plays a similar role in cholesterol in humans and animals.
Vitamin D3 in supplement form, on the other hand, is made by exposing lanolin, a natural fat from sheep’s wool, to ultraviolet light. This process results in a highly assimilable and bioavailable form of vitamin D, that according to some research, the body uses twice as effectively as vitamin D2.
So why would some people still supplement with vitamin D2 then? There are a few reasons: the most common for supplementing with vitamin D2 is if you’re a strict vegans or for those avoiding animal products.

Importance and benefits of vitamin D3 (at all ages!)
No matter what kind of vitamin D you prefer to supplement with, some things don’t change either way. The importance and benefits of vitamin D3 at all ages is one of them.
Vitamin D is an essential fat-soluble vitamin, which means there’s few bodily processes it is not involved in. Most importantly, vitamin D3 helps the body absorb calcium, a critical mineral for all things bone health, blood flow, muscle and nerve function, and protecting the heart and brain.
Benefits of vitamin D3 include:
- reduce inflammation
- protect against osteoporosis
- improve immune function
- maintain the health of bones and teeth
- mood support
- and more!
Everyday symptoms of a vitamin D deficiency
The most pronounced symptoms of vitamin D deficiency are rare today. Rickets in children and osteomalacia in adults cause the softening of the bones and are associated with vitamin D deficiency.
But in fact, osteomalacia is caused by a deficiency in calcium and phosphorus, which require a steady supply of vitamin D to be efficiently absorbed. Another bone condition, osteoporosis, is caused by vitamin D deficiency. Symptoms of osteoporosis include low bone density and increased risk of fractures. Women over 50 are at higher risk when it comes to developing osteoporosis, so vitamin D supplementation is often recommended by healthcare professionals.
Everyday symptoms of low vitamin D are very common. Look out for: brittle hair and nails, low back pain, muscle pain and weakness.
Food sources of vitamin D
This particular vitamin is hard to obtain from food alone, which is why supplements are so popular. Good dietary sources of vitamin D include:
- fatty fish such as: tuna, mackerel, salmon
- cod liver oil
- egg yolks
- butter
- kidney and liver (from a high quality meat source)
Even for omnivores, getting enough vitamin D from food alone is a stretch. As such, getting a good quality supplement is essential for vegans and vegetarians.
How much vitamin D3 should I take daily?
Vitamin D3 is measured in international units (IU). The recommended daily allowance, which represents the lowest amount necessary to maintain good health, is 400 IU per day for children to 800 IU per day for adults.
However, many health practitioners recommend a daily dose of 2500 IU for children 9 years and older, adolescents and adults. Find a vitamin D3 supplement in softgels or in convenient vitamin D3 drops – which are also easier for the kiddos. Tip: Softgels suspended in coconut oil triglycerides increase absorption.
