How Much Vitamin D Do I Really Need? And Other Vitamin D FAQs


What is Vitamin D3?

Vitamin D3, or Cholecalciferol, is the biologically active form of Vitamin D found naturally in our bodies. Vitamin D3 is converted from cholesterol when sunlight hits our skin, hence its nickname “the sunshine vitamin.”

Vitamin D3 behaves less like a traditional vitamin and functions like a steroid hormone. Vitamin D2 is found in non-animal products, fungi and plants, but it is much less potent in its benefits and effects.

How Much Sunlight Do I Need To Get Adequate Vitamin D?

In order to get the adequate amount of Vitamin D3 that the body needs, you would need to spend 15-20 minutes per day in full, direct sunlight. However, dark winter months, certain latitudes and long days in the office all make it difficult to get the needed Vitamin D from sun exposure each day. What’s more, sunscreen can block the reaction needed to produce Vitamin D3 in our bodies. But prolonged sun exposure without sunscreen carries its own risks.

Can I Get Vitamin D From A Tanning Bed?

While you can get Vitamin D from a tanning bed, a tanning bed is not a replacement for sun exposure for the purposes of getting proper Vitamin D. UVB rays, which the skin uses to produce Vitamin D, are found in tanning beds. However, most tanning beds primarily use harmful UVA rays, which greatly increase the risk of skin cancer and age the skin. There are much safer ways to get the recommended amount of Vitamin D - through foods or supplements.

What Foods Contain Vitamin D3?

Thankfully, Vitamin D3 is also found in many animal products including milk, eggs, sardines and Cod liver oil. But for many, Vitamin D deficiency becomes a problem when sunlight and naturally occurring Vitamin D from foods is not enough. A third source of Vitamin D is supplements like Jarrow Formulas Vitamin D3 5000 IU.

What Are The Benefits Of Vitamin D?

Vitamin D is an essential vitamin for proper calcium absorption. Without it, the health of your bones and teeth can suffer. Vitamin D also plays a role in regulating the immune system and is said to be important for the prevention of autoimmune diseases. It is also taken as a mood booster to combat depression.

Some studies have shown that taking Vitamin D supplements lowers the risk of specific types of cancer.  

How Much Vitamin D Do I Need?

Depending on your Vitamin D levels, you may need to take between 400, and some organizations even recommend up to 5,000 IU daily. A blood test is the best way to tell if you have a Vitamin D deficiency and to understand the proper dosage based on your specific health needs. Your diet, weight, sun exposure, latitude, race and age may all affect your levels of necessary Vitamin D intake per day.
