Choose one with no more than 100 percent of the U.S. RDA for each nutrient. Supplements at levels exceeding the U.S. RDA do not improve the performance of a well-nourished athlete. To save money, consider the generic or store brand. They are less expensive because there is no cost of national advertising to pass along to the consumer. The less expensive pills may be from the same batch as the higher priced ones but without the brand-name price.
Supplements lose their potency over time.
Supplements can only complement, not replace a healthy diet. Your best nutritional resource for optimum performance is eating a variety of wholesome, nutritious foods.
