Vitamin D-3 by Now Foods is a food supplement that provides the organism with an optimal dose of vitamin D, a vitamin that regulates many of the bodys processes.
The most well-known function is that of absorbing calcium in the intestine. It thereby regulates levels of calcium in the blood and its deposit in the bones. If we do not add sufficient vitamin D, there will be less calcium in the blood and ones. The bones could break or grow malformed (osteomalacia and rickets). If this happens as an adult or in the elderly, there is a greater chance of fractures and diseases such as osteoporosis. Vitamin D also intervenes in many other processes.
If calcium is lacking it is easier for autoimmune diseases such as diabetes to appear, as well as some types of cancer. People can obtain just a fraction (some 10%) of the daily recommended amount from food sources and very little from solar light. It is therefore highly recommended to eat more fish and reinforced foods, take a little more sun and add supplements that provide an optimal dose of vitamin D, above all during seasons of the year with scant sunshine, such as autumn and winter.
