It makes sense to think about what you take and why. Secondly, mega dosing on nutrient supplements may not only be harmful but also wasteful. The body uses some nutrients in such microscopically small amounts that it simply excretes any surplus as waste. So please, don't waste your money. Thirdly, supplements are no magic bullet.
Different cells have different replacement rates.
Whilst some cells, such as neutrophils and macrophages, which deal with bacteria and particulate debris, have half lives of less than 12 hours and are replaced by the body twice a day, other cells have far longer regeneration times. Blood cells, for example, can take 2 to 4 months months to be replaced, muscle cells 6 months and bone cells as long as 12 months. Clearly, as anyone undertaking training knows, it takes time to get one's body into really great shape. Supplementation therefore needs time for the benefits to work fully into the system. Fourthly, it is worth bearing in mind that nutrients work synergistically.
