As more people avoid sun exposure, Vitamin D supplementation becomes even more necessary to ensure that your body receives an adequate supply.
Vitamin D3 supplementation is the key to get the necessary amount of Vitamin D without sunbathing. Vitamin D is normally obtained from diet or synthesised by skin from the ultraviolet energy of the sun, however, it is not abundant in food.
Vitamin D is important to the body for various different functions:
Muscles need it to move, for example, nerves need it to carry messages between the brain and every part of your body and the immune system needs vitamin D to fight off invading bacteria and viruses.
Together with calcium vitamin D also helps protect elderly people from osteoporosis.
Vitamin D is needed to absorb calcium and strengthen bones and teeth and can prevent the onset of osteoporosis.
Vitamin D up-regulates your ability to fight infections, as well as chronic inflammation. It produces over 200 antimicrobial peptides, the most important of which is cathelicidin, a naturally occurring broad-spectrum antibiotic. This is one of the explanations for why it can be so effective against colds and influenza.
