Vitamin D is present in very few foods, many of which are animal products. This fact has caused assumptions that vegans and some vegetarians are the only ones who suffer from the deficiency. However, this is far from the truth. In fact, it’s hard for most individuals, whatever their diet, to get their recommended daily allowance (RDA) of vitamin D.
The biggest source of vitamin D is sun exposure, but it isn’t as easy as just stepping outside for a little while. Many things can block the skin’s absorption of the vitamin, such as sunscreen, hats, sunglasses and even clouds. In addition, the amount of time in the sun needed varies from person to person, depending on their skin color and how dark it is, according to the American Academy of Dermatology (AAD). For instance, a fair-skinned individual only needs to be in the sun for 10 to 15 minutes a day, whereas a dark skinned-person needs much longer.
Since the absorption of vitamin D is so inconsistent to begin with, the AAD recommends that individuals get their RDA from a supplement, such as Dr. Pinkus’ Sublingual Vitamin D-3 made by Dr. Newton’s Naturals.
