For general health and muscle building, creatine is a non-negotiable 'must-have' supplement due to its safety and effectiveness. Beta-alanine is beneficial for athletes to buffer acidity and prevent fatigue, though less critical for general fitness. Essential amino acids (EAAs), particularly BCAAs, are also important for those not consistently hitting protein targets, especially older individuals looking to boost muscle protein synthesis. Timing for creatine can be flexible, but beta-alanine is best taken before workouts for its ergogenic effect.

Significance (High): This provides a clear, prioritized list of supplements, helping individuals navigate the crowded market. Understanding the rationale and timing for each can optimize their effectiveness and investment in supplementation.
