The study is small, so we can’t draw too many conclusions, but there is evidence indicating that the vitamin D we get from sunlight stays active in the body longer than the vitamin D we get from supplement form. This study, which was published in the Journal of Clinical Investigation in 1993, looked at the impact of vitamin D levels from UVB light exposure vs. However, the fact remains that under “natural” circumstances, vitamin D is mainly obtained through exposure to sunlight, where it is generated by the cells of the skin. Not all of us have the complexion for sustained time outdoors. The benefit of supplements is that they reduce the risk of skin cancer from an excess of sun exposure. The body can use supplemental and sunlight derived vitamin D in exactly the same way. They are functionally the same and can both boost vitamin D levels to a healthy range. supplementsĪccording to Yale Medicine, vitamin D derived from sunlight is no better than the Vitamin D we get from supplements. The foods we eat contain some vitamin D, but often not enough for many Americans to avoid vitamin D deficiency, which is estimated to occur in 41% of the population and is thought to be particularly acute in African American populations. D2 is derived from plants and is vegan friendly, whereas vitamin D3 supplements are usually animal derived.īoth D2 and D3 “work” as supplements because both forms of vitamin D help the body make calcitrol, the bioactive form of vitamin D produced when UVB light hits the skin and interacts with cholesterol. There are two types of vitamin D we can take in supplemental form – vitamin D2 and vitamin D3. The body’s ability to utilize calcium from vitamin D plays a big role in bone density and bone health, which we covered previously in this post. It’s a fat soluble vitamin that helps us absorb calcium from the intestines. Should we grab a beach towel and lay out in the sun, or is a supplement better? We want to make sure we are getting the Vitamin D we need. Many of us are interested in the crucial role vitamin D plays in strengthening the immune system.
