Known as the sunshine vitamin, vitamin D is activated in the body during exposure to sunlight. Vitamin D is also found in some fish, fish liver oils, and egg yolks, and in fortified dairy and grain products.
Vitamin D helps the body use calcium and is essential for strong bones. Research indicates that vitamin D may play a role in the prevention and treatment of diabetes, hypertension, glucose tolerance, and multiple sclerosis. A low level of vitamin D can increase the risk of death from cardiovascular disease, cognitive impairment, asthma, and even cancer.
Bone pain and muscle weakness can be symptoms of a vitamin D deficiency, although many people have no symptoms.
Supplementation of 1000-2000 International Units of vitamin D is recommended after bariatric surgery to prevent a deficiency. Higher levels of supplementation may be recommended if a vitamin D deficiency exists.
