1 Protect your hands when it's cold outside to keep your nails from getting brittle and give them the chance to grow long.  Get plenty of sun, even in the winter, since the sun helps your body create the vitamin D your nails need to grow faster.
Severe vitamin D deficiency can cause rickets in children and osteomalacia (âsoftâ bones) in adults. Yet, vitamin D is more than a vitamin. It really is a prohormone, a substance that the body converts to a hormone. The skin makes vitamin D after exposure to sunlight. We also absorb vitamin D from certain foods, such as dairy products and certain oily fish, such as salmon, mackerel, and sardines. Vitamin D has its effects by binding to a protein (called the vitamin D receptor).
