Once in the body, vitamin D is converted by the kidneys into its active form, the hormone Calcitriol. In it’s active form, Vitamin D works to support numerous essential body functions such as bone formation and the immune system.

How is low Vitamin D detected?


Vitamin D deficiency is easily detected with a blood test. Although levels greater than 30 ng/mL are considered “normal”, most experts agree that the optimal level is greater than 50 ng/mL.


How does one get enough Vitamin D?


Sun exposure is the best source of Vitamin D. The amount of sun exposure needed varies based on location, time of day and the person’s complexion. For example, a dark-skinned person far from the equator would need more sun exposure than a light-skinned person located close to the equator. The time of the day is also an important factor because UV light absorption peaks at noon. Sun exposure between 10 AM and 3 PM is usually effective though.


Dietary sources of Vitamin D are important as well. Foods such as egg yolks, mackerel, salmon, tuna and sardines, fortified foods and dairy products are good dietary sources of vitamin D.


Vitamin D supplements are often recommended for treatment of low vitamin D levels and also for prevention of low Vitamin D. Vitamin K₂ is a Vitamin that helps with regulating calcium absorption and should be taken with Vitamin D supplements. The recommended dose for supplements will vary. Your primary care physician can tell you how much Vitamin D you should be taking. It is possible to overdose on Vitamin D supplements so it is important to only take the recommended amount.
