Vitamin D ensures our body absorbs sufficient calcium. Calcium is required for metabolism, heart and muscle function, and, along with phosphorous, is a key component of bone structure. If your body does not get enough Vitamin D, you are at risk for developing bone abnormalities such as soft bones (osteomalacia) or fragile bones (osteoporosis). Although it has not been proven, Vitamin D may help to prevent falls, boost weight loss, fight infections (colds and flus) and reduce your risk for diseases such as multiple sclerosis. To obtain these potential benefits, most adults need to take 1000 I.U per day. You should never exceed more than 4000 I.U per day unless you are severely deficient, as diagnosed by your doctor. Your body also limits the amount of Vitamin D it gets from the sun, so it is safe to continue with supplementation well into the summer months.
