It is common knowledge that vitamin D plays an important role in helping the body to absorb calcium and in bone mineralisation. 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. Vitamin D deficiencies can occur when exposure to sunlight is limited or as the body ages the ability to produce vitamin D is impaired. USANA’s Vitamin D supplement is formulated with maximum strength to help you achieve an adequate level of vitamin D in one tablet. Vitamin D helps to maintain healthy bones and supports efficient calcium absorption. It is necessary for normal bone mineralisation and important for the maintenance of muscle strength. It supports robust and healthy immune function. Vitamin supplements should not replace a balanced diet. USE ONLY AS DIRECTED. ALWAYS READ THE LABEL.
