Sports supplements have become increasingly popular due to their role in enhancing endurance, strength, and recovery. While macronutrients provide energy, micronutrients play a key role in metabolic processes, muscle function, and immune support. Sports supplements can be classified into protein-based supplements (protein powders, protein drinks, gainers) that support muscle repair and growth through protein synthesis; energy and recovery products (sports drinks, energy bars, branched-chain amino acids, sports gels) that help replenish glycogen and boost ATP production for sustained energy; endurance and strength enhancers (creatine, beta-alanine, nitric oxide boosters) that improve stamina by increasing cellular energy and blood flow; and immunity and health boosters (vitamin-enriched supplements, adaptogens, probiotics) that protect against oxidative stress, support immune function, and maintain gut health. Although these supplements offer benefits, excessive or improper use can lead to side effects such as micronutrient imbalances, digestive issues, or contamination risks. Each micronutrient (whether vitamin or mineral) has a specific role to play in terms of the performance of a sports person. Most marketed sports supplements have either vitamins(s) or minerals(s) or both. This chapter explores the global sports supplement market, different types of supplements, and the importance of micronutrients in the performance of a sports person.
