If dull or thinning hair and less-than-glowing skin has you reevaluating your everyday beauty routine, then you might want to hold up a sec and consider this vitamin D, or lack thereof, might be the source of your frustration.
Vitamin D is a fat-soluble vitamin that is necessary for the proper function of our hair and skin. In fact, vitamin D promotes proper calcium absorption in your gut, according to the National Institutes of Health (NIH). This means the vitamin keep your bones from becoming thin and brittle, and — along with calcium — even thwarts against osteoporosis.
Sunlight plays a major role in helping your body to generate vitamin D, but not in the way you might think. In fact, doctors are quick to assure patients that obtaining vitamin D from sunlight does not mean laying out in the sun or using a tanning bed.
Adding that you’re better off taking a vitamin D supplement or eating vitamin D-rich food to boost your levels. Solid food sources of the vitamin include cod liver oil, salmon, swordfish, vitamin D fortified milk, sardines, and eggs.
As always, if you suspect a vitamin D deficiency might be the culprit behind your drab hair or skin, talk to a healthcare professional before making any dietary changes or taking a supplement.
