Which of the following supplements is not banned by the NCAA?

The correct answer, which is EGCG (Epigallocatechin gallate), is not banned by the NCAA because it is a naturally occurring compound found in green tea. EGCG is often studied for its potential health benefits, particularly in relation to weight management and antioxidant properties. Unlike substances such as clenbuterol, which is a performance-enhancing drug, or ephedrine and citrus aurantium, both of which have stimulant effects and have been banned due to safety concerns and their potential to enhance athletic performance, EGCG does not possess the same risk profile. This distinction allows it to be utilized by athletes without concern for violating NCAA regulations, emphasizing the importance of understanding the regulatory landscape surrounding dietary supplements in sports nutrition.
