Health Aid Vitamin D3 1000IU, 120tabs
 
It is the most studied vitamin, as it is necessary in many biological functions of the body, with the most important being the absorption and utilization of calcium and phosphorus to maintain the health of bones and teeth.
It can be produced by the body through the skin after sun exposure. Nevertheless, studies have shown that a very large part of the world's population shows a lack and even a deficiency of the vitamin. Its deficiency has been associated with the appearance of osteopenia & osteoporosis, especially in women during menopause, with rickets & osteomalacia in children and with cardiovascular problems, such as hyperlipidemia, obesity, blood pressure.
It provides great protection to the immune system against infections, especially of the respiratory system during the winter months (less sunshine).
Necessary for the elderly, who are prone to bone fractures, for women during menopause, but also ideal for those who are not exposed to the sun enough, for various reasons.
