Commonly recommended supplements for athletes include protein powders, branched-chain amino acids (BCAAs), and creatine. Protein powders aid in muscle recovery and growth post-exercise, while BCAAs may help reduce muscle soreness and fatigue. Creatine is known to enhance athletic performance, especially in high-intensity activities. Additionally, vitamins and minerals like omega-3 fatty acids, vitamin D, and magnesium support overall health and performance. However, athletes should consult with professionals before starting any supplementation.
