Vitamin D is known to help both the muscles and bones. It enhances the absorption of calcium in the small intestine. Research shows that vitamin D can aid in reducing fractures and improve muscle strength. In addition, high levels of dietary vitamin D3 may be suitable for achieving a higher peak bone mass in adulthood and thereby preventing osteoporosis.3
Research has shown that vitamin D may help protect against acute respiratory infections. “The study found that daily or weekly intake of the supplement benefited individuals who had a deficiency (blood levels below 10 mg/dl) and cut their risk of respiratory infection in half.” All the individuals who participated experienced some benefit by taking regular supplements.
