Why Vitamin D is Important for Your Health

Vitamin D, like all nutrients, is essential for life. Our bodies need it from our environment (sunlight and food in this case) to function. It also plays an important role in building and maintaining strong bones. But that’s not all. Every cell in our body has receptors for vitamin D, meaning it can affect virtually everything that happens inside our cells. Research shows that people with higher blood levels of vitamin D live better for longer, with immune and cardiovascular systems that function better.

Optimize Your Vitamin D Level in 3 Easy Steps

Sunlight is necessary for our skin to make Vitamin D on its own. But most of us don’t spend hours in the sun each day. In fact, we are living more of our lives inside, which makes tracking Vitamin D levels more important than ever. Once you know your blood level, you will know if your diet and lifestyle are able to maintain a desirable level of Vitamin D. We can then provide personalized guidance on how to improve your levels through sun exposure, diet and supplementation.
Following 3 simple steps can help you achieve optimal levels of vitamin D:

1 Measure

Measure

Exposure to sunlight, eating vitamin D-rich foods and taking supplements does not guarantee that your blood level will be in the desirable range — it must be measured.

This recommendation is meant to be a guide for how much supplemental Vitamin D you may need in your diet to reach your Vitamin D blood target, based on research by van Groningen et al. 2010. Up to 4,000 IU per day of supplemental Vitamin D is considered safe and is set as the upper limit in this calculator. The calculation is only valid for body weights up to 125 kg (275 lbs). Due to the seasonal effect on Vitamin D blood levels, we also suggest testing once per season to adjust your supplementation. Please consult your healthcare provider before making changes to your diet or supplementation regimen. Learn More...

How can I increase my Vitamin D level?

The Vitamin D test measure how much your body creates from sun exposure and consumption through your diet or supplementation. Below we provide some information about how to improve your Vitamin D level from the sun, diet and supplements.

From the Sun
Vitamin D3 is the primary raw material to make active and useable vitamin D.  Vitamin D3 is produced when our body is exposed to sunlight (ultraviolet B radiation sunlight).  Our bodies are amazingly efficient when it comes to producing vitamin D3; brief sunlight exposure of the arms and face will enable our body to produce 200 international units (IU) of vitamin D3. The precise amount of vitamin D3 produced will vary depending on factors such as skin type, geographical location, season, and time of the day.  For example, an individual will produce 400 IU of vitamin D3 in Boston, Massachusetts within 8 minutes of sunshine whereas the same individual may only need 6 minutes if they are in Miami, Florida.  Not a huge difference but something to celebrate if you are reading this from South Beach.
Supplements
Correction of vitamin D deficiency is quite simple with the use of over-the-counter vitamin D supplementation.  The American Geriatrics Society recommends vitamin D dose of 800 to 1000 IU by oral supplementation daily to reduce the risk of falls and fractures.  Most pharmacies carry vitamin D in doses of 400 IU to 2000 IU per tablet. Other formulations such as a liquid formulation is available for children and an injection for people with gastrointestinal absorption issues.  People with kidney or liver disease will need to see a specialist because the over-the-counter vitamin D is the inactivated form and in the presence of kidney or liver disease, our body cannot convert this inactivated form to its active metabolite (our liver and kidneys convert vitamin D to its active form). There are virtually no side effects with vitamin D because it is a natural hormone.  The Institute of Medicine recommends an upper limit of 4000 IU of vitamin D per day.   In cases where there is vitamin D toxicity, calcium levels may be too high but this is extremely rare.
Diet
Vitamin D can come from our diet but there are very few foods in nature that contain vitamin D (e.g. fatty fish liver is the best source but who wants to eat that).  The best sources of Vitamin D in nature come from fatty fish (salmon, tuna, mackerel) and small amounts are also found in cheese, egg yolks, sardines and fortified foods.
