Mushrooms, Sunlight, and Supplements: Three Sources to Get Vitamin D on a Vegan Diet

Vitamin D is an essential vitamin that the body requires for immune system modulation, bone health, and muscle strength. With low levels of Vitamin D, you are more susceptible to the common cold and flu.

Additionally, Vitamin D aids calcium absorption. When your body contains lower levels of it, you are at higher risk for bone fractures, osteomalacia, osteoarthritis and osteoporosis.

Dangers of Vitamin D Deficiency

What puts you at risk for Vitamin D deficiency?

If you spend a lot of your time indoors (which a lot of us do!) you could be at risk for Vitamin D deficiency. Vitamin D is the only vitamin that the human body actually produces.

Getting Enough Vitamin D from Sunlight

In order for the body to synthesize Vitamin D, you must expose your body to direct sunlight to receive ultraviolet B rays (UVB rays). Those who have lighter skin don’t need as much direct sunlight as those with darker skin need to produce Vitamin D.

That being said, Vitamin D deficiency is not a “vegan thing”; everyone is susceptible to being deficient in it.

The wintertime also increases your risk for Vitamin D deficiency since there is less sunlight. Going out in the middle of the day when the sun is strongest may help expose you to UVB rays.

In order to get enough Vitamin D, you will likely need to eat foods and supplement your diet with it throughout the winter.

Getting Vitamin D as a Vegan from Mushrooms

A natural way to get Vitamin D as a vegan is through mushrooms. In a study, it was found that mushrooms actually synthesize Vitamin D the way humans do; mushrooms absorb sunlight through their skin to produce D2.

In the same study, it was reported:

“These results provide evidence that ingesting mushrooms which have been exposed to ultraviolet light and contain vitamin D2, are a good source of vitamin D that can improve the vitamin D status of healthy adults.

Furthermore we found ingesting mushrooms containing vitamin D2 was as effective in raising and maintaining a healthy adult's vitamin D status as ingesting a supplement that contained either vitamin D2 or vitamin D3".

  • Source: Boston University Medical Center
  • Summary: Researchers have discovered that eating mushrooms containing Vitamin D2 can be as effective at increasing and maintaining vitamin D levels (25–hydroxyvitamin D) as taking supplemental vitamin D2 or vitamin D3.

Therefore, mushrooms are a healthy way to get Vitamin D, and are just as efficient as taking a supplement.

D3 typically comes from animal sources, but if you are eating a variety of mushrooms, you can get enough Vitamin D in a vegan diet. Some mushroom varieties include portobello, shiitake, crimini, maitake, lion’s mane, oyster and so many more! In addition to containing Vitamin D, mushrooms are a great source of protein in a vegan diet.

Getting Vitamin D with Vegan Supplements as a Source

Another way to get Vitamin D is through a supplement. Vitamin D is an affordable supplement, and easy to find in most health food stores and in pharmacies. Most commonly, it comes in pill/capsule form.

If you are vegan, make sure to check supplement labels for ingredients; not all Vitamin D supplements are vegan.

Getting Vitamin D Through Fortified Vegan Foods

Lastly, Vitamin D is commonly supplemented in food and drink products. If you check your cereal boxes, plant-based milks, and other packaged foods, it is likely that you will see added Vitamin D. Labels on these types of food will typically read, “Fortified with Vitamin D”.

However, it is unclear how much of the Vitamin D that the body actually absorbs from fortified foods. Getting Vitamin D from the sun and foods containing naturally occurring Vitamin D should be your first choice, and then supplementing with Vitamin D and fortified foods can be your back-up plan.

A Note from the Founder of Vegan Health Pack: Being deficient in Vitamin D was one of the reasons why I started this website. While we offer natural vitamin D sources through mushroom extracts, and promote getting Vitamin D naturally through sunlight, a doctor told me that I had to take a supplement 2x a day to get back to my normal levels.

If you are concerned about your Vitamin D levels, ask your doctor to test your current levels and what they recommend for supplementing.
