Did you know that...? Recent studies link low Vitamin D (25-Hydroxy Vitamin D) levels with anorexia nervosa, impulsivity, and eating disorders. Vitamin D is converted from cholesterol in the skin by UVB radiation from the sun. This initial vitamin must be converted in the liver to 25-hydroxy vitamin D, and then by the kidney to its active form, calcitriol. Vitamin D deficiency is listed as below 20 ng/mL (50 nmol)L but many health experts, including the endocrine society, recommend 40-60 ng/mL (100-150 nmol/L) to prevent disease. If you don't get daily sun exposure or have absorption problems, you should discuss Vitamin D supplementation options with your doctor.
