The Facts on Vitamin and Mineral Supplementation for Athletes
It is estimated that in the United States alone last year consumers spent close to 30 billion dollars on vitamin and mineral supplements. But are vitamin supplements necessary? And if so, who is most likely to need to supplement and what vitamins are actually necessary? And can some of these vitamins make us sick in excess? Surprisingly, of the consumers spending that money for vitamin supplements, very few are likely well informed about why these nutrients are even necessary (if they are necessary at all). And the vitamin industry is not in any rush to educate consumers willing to spend 30 billion dollars.
This book is written for the person that is probably able to benefit the most by vitamin and mineral supplementation, and that is someone who is active or involved in athletic activities. The truth is, it is likely that someone who leads a passive lifestyle and eats a well rounded diet has little need to take vitamin supplements. However, as individuals increase their activity levels or put their bodies under specific training workloads, it is beneficial to understand the types of vitamin deficiencies that can occur. This is especially important for those who follow a strict vegan or raw organic food diet.
