❓ Frequently Asked Questions
What are the primary performance benefits of creatine, beta-alanine, and caffeine?
Creatine can increase strength and lean mass with resistance training. Beta-alanine helps delay fatigue during high‑intensity efforts by buffering acidity. Caffeine can boost endurance, sprint performance, and alertness/cognitive function.
How should creatine be taken for best results?
Commonly 3–5 g per day. Loading (e.g., 20 g/day for 5–7 days) is optional. Use creatine monohydrate, take with water or a meal, and stay hydrated; benefits accumulate with consistent use over weeks.
What is beta-alanine's role in performance and what are common side effects?
Beta-alanine increases muscle carnosine to buffer acidity and delay fatigue in high‑intensity work. Typical dose is 2–5 g/day. Large single doses can cause a tingling sensation; splitting doses can minimize this.
How should caffeine be used to boost performance and what precautions should you consider?
Caffeine (about 3–6 mg/kg body weight) taken 30–60 minutes before exercise can improve endurance, sprint performance, and perceived effort. Effects vary by person; watch for jitters, stomach upset, or sleep disruption, and avoid late in the day or if caffeine-sensitive.
