With the world of nutritional supplements ever-expanding, it is hard to keep up with “what you should and shouldn’t be taking” on a daily basis. Supplements are not only sold online, in health food stores and at designated vitamin stores, but at gas stations too. What you probably do not know, though, is that you can take numerous pills per day, and they won’t necessarily absorb into your body’s systems. This is why bioavailability is so important.
What is Bioavailability?
Bioavailability of a drug (in pharmacology) or vitamin is its ability to be absorbed and processed by the human body . During testing for new pharmaceutical drugs, the rate of absorption is examined thoroughly. In order to gain approval from the Federal Drug Administration (FDA), drugs must absorb at a consistent rate.
While nutritional supplements are unregulated by the FDA, the same principles chemically apply – you can literally take vitamins and other supplements daily, but reap no benefits if you don’t help to make them bioavailable.
