Recommendation Guidelines Supplements and Ergogenic Aids Is current dietary intake adequate? Is there an indication of increased need? Is the amount below toxic levels? Can product cause harm? Does the athlete want to supplement? What do they believe it will do for them? Can I recommend an alternative substance or food?
Recommendation Guidelines Supplements and Ergogenic Aids Is the athlete willing to make dietary changes to improve performance? What is the cost of the product and is it a reputable manufacturer? Are their any nutrient-nutrient or drug-nutrient interactions? Are there ethical issues? Is it banned or restricted by any credible organization?
