Get your "Sunshine Vitamin" with Swanson Higher Potency Vitamin D3! Vitamin D has received a lot of press by researchers and health professionals. It is best known for promoting bone, immune and emotional health. Optimal levels of vitamin D are also associated with improved muscle strength and blood pressure maintenance. Your body actually makes vitamin D when skin is exposed to sunlight. For anyone who spends little to no time in the sun, though, supplements may be helpful. The elderly in particular have been known to have low levels of vitamin D as our ability to produce it diminishes with age. According to the National Institutes of Health, most people in the United States consume less than recommended amounts of vitamin D. Help ensure you're getting enough of this important nutrient with 2,000 IU (50 mcg) of D3 as cholecalciferol from Swanson Higher Potency Vitamin D3.
