Vitamin D3 is a form of vitamin D that the body manufactures when skin is exposed to UV radiation from the sun. Vitamin D is necessary for the maintenance of healthy calcium and phosphorous levels in the body. Calcium, the main structural element in bones and teeth, can only be absorbed by the body when vitamin D is present. Vitamin D is therefore essential for building and maintaining healthy bones and teeth. It's also believed to contribute to increased muscle strength, which may help improve balance and reduce the risk of falls among the elderly. Vitamin D also plays a part in regulating cellular growth and keeping the nervous and immune system functioning properly. Vitamin D can also help maintain healthy blood pressure, blood sugar and overall cellular health. It's estimated that a significant percentage of adults suffer from vitamin D deficiency. Vitamin D deficiency is associated with a variety of health complication, including rickets (in which bones are unable to properly calcify, or harden) in children, poor prostate health in men and poor bone health in older adults. The elderly, alcoholics and strict vegetarians are particularly at risk for deficiency and should consider regular supplementation. Individuals with darker skin pigments may also be at increased risk, as darker skin contains higher levels of melanin, which may inhibit the skin's ability to produce vitamin D from sunlight. Also, people with intestinal malabsorption, hyperthyroidism, liver or kidney disease, or pancreatic conditions may be at risk. Recent studies suggest that the current RDA/DV of vitamin D (200IU for individuals under age 50, 400 IU for those between the ages of 50 and 70, and 600 IU for those over the age of 70) may not be adequate. In fact, optimal levels are between 2,000 and 4,000 IU per day. 2000 IU per capsule. 100 veggie caps
