Muscles require rapid cellular energy during heavy lifting or sprinting. Creatine replenishes this intramuscular “emergency battery” by increasing phosphocreatine stores. This enables higher power output, increases explosive strength, and accelerates lean muscle mass gains.

Accumulation of hydrogen ions during high-intensity bouts leads to the familiar “muscle burn” and fatigue. Beta-alanine elevates intramuscular carnosine levels, acting as a buffer to neutralize acid buildup. It effectively delays fatigue in high-intensity efforts lasting 1–4 minutes.

Nitrates convert into nitric oxide, inducing vasodilation. Expanded blood vessels deliver more oxygen and nutrients to active muscles, improving endurance capacity while reducing the oxygen cost of exercise.

Caffeine blocks adenosine receptors, preventing the brain from receiving fatigue signals. It enhances mental alertness, shortens reaction times, and blunts perceived pain and exertion during training.

Exercise causes micro-tears in muscle fibers. Protein delivers the essential building blocks (amino acids) to repair damage, accelerate recovery, stimulate hypertrophy, and maintain immune function.

Common baking soda serves as an extracellular buffering agent in the bloodstream. It neutralizes systemic acidosis during high-intensity efforts, delaying muscle failure in all-out bursts lasting 1–7 minutes.
