Supplementing according to the body's needs is critical. Essentially, the point of supplementation is to compensate for the gaps in one's diet and to provide the body with nutrients that are essential for bodily functions. When trying to determine what supplements to incorporate into my daily supplement routine, I came across this reliable site (WebMD) that addresses one's needs for supplements according to their age. I have attached a link to direct those who are interested to the site directly.
