42% of Americans in the United States are Vitamin D deficient. If you've gone to the doctor recently for a routine exam and they've done a blood panel, their is a good chance that your doctor has told you that you have a deficiency of Vitamin D and will recommend that you take a supplement. Other than bone health, most people don't associate Vitamin D with skin health. However, Vitamin D plays an important role in the health of your skin.
Vitamin D contributes to skin cell growth, repair, and metabolism. It optimizes the skin's immune system and helps destroy free radicals that can cause premature aging. Amazingly enough, our bodies can manufacture Vitamin D through sunlight. The double-edge sword is that the sun and it's ultra-violet rays is what accelerates the aging process causing lines, wrinkles and hyper-pigmentation. Additionally, sunblocks while being extremely important, block Vitamin D production. The solution is rather simple...supplement your bodies need with a supplement.
According to the Mayo Clinic, the recommended daily amount of vitamin D is 400 international units (IU) for children up to age 12 months, 600 IU for ages 1 to 70 years, and 800 IU for people over 70 years.
