- Necessary for normal bone mineralization and growth
- Helps in the development and maintenance of bones and teeth
- Helps in the absorption and use of calcium and phosphorus
- Helps to prevent vitamin D deficiency
- The current recommendation of 400 IU of vitamin D per day may not be enough to prevent vitamin D deficiency. USANA’S supplement has 1000 IU of vitamin D per tablet.
It is common knowledge that vitamin D plays an important role in helping the body to absorb calcium and in bone mineralization. However accumulating scientific evidence is proving that vitamin D provides more health benefits than simply bone health. Evidence is emerging that there is wide spread vitamin D deficiency in the broader population, especially people in North America.
Vitamin D deficiencies can occur when exposure to sunlight is limited or as the body ages the ability to produce vitamin D is impaired.
It supports robust and healthy immune function.
Vitamin D Supplementation, All Year Long
|Vitamin D3 (Cholecalciferol)||25 µg|
Studies have shown that because our bodies use sunlight to make vitamin D, people in North America can become vitamin D deficient during the winter months. But even when the sun is shining, how often do you actually see it? If you’re like most people, not often—especially if you work in an office or never leave the house without covering yourself in sunscreen. USANA’s Vitamin D supplement is formulated with a high level of vitamin D to ensure you get the nutrients you need throughout the entire year – not just in the winter months.
How Vitamin D Helps
Calcium is the major structural element of bones and teeth. Your body needs several nutrients in order for calcium to be absorbed and used properly; including vitamin D. Vitamin D increases absorption of calcium from the small intestine so the body receives maximum benefit. Deficiencies in vitamin D can increase the risk of calcium deficiency, which, in turn, can lead to accelerated bone loss and osteoporosis.
Cholecalciferol (Vitamin D3)
USANA’s Vitamin D supplement is made with cholecalciferol (vitamin D3), which research suggests is better than competing forms at raising levels of vitamin D in the blood. Cholecalciferol can be acquired through diet and exposure to sunlight. Light-induced synthesis occurs in the skin when ultraviolet light reacts with a form of cholesterol, converting it to cholecalciferol. This molecule is then altered by the liver and kidneys to form the physiologically active vitamin D. Several forms have vitamin D or potential vitamin D activity. The most important forms are vitamin D2 and vitamin D3. The latter is the form normally found in humans and is also the form used in USANA’s Vitamin D supplement.
Why Vitamin D?
Even when the winter months are behind us, it doesn’t mean your body needs less of a good thing. Every cell in your body needs vitamin D to function properly. USANA’s Vitamin D supplement is a safe and easy way to get 1,000 IU of maximum-strength vitamin D.
