Adherence
Bodybuilders primarily rely on fitness coaches and registered dietitians for information regarding dietary supplements, rather than independent medical advice or rigorous scientific literature.
When choosing supplements, prioritize advice from registered dietitians or nutritionists over fitness coaches, as coaches may lack specific nutritional expertise. This reduces the risk of misinformation and adverse effects.
