How to Choose a Bodybuilding Supplement That Actually Builds Muscle
The bodybuilding supplement aisle is dominated by hype and underdosed formulas. These are the ingredients with real RCT evidence for hypertrophy, strength, and recovery.
- Creatine monohydrate (3β5 g/day): The most studied supplement in sports nutrition. Over 1,000 published trials confirm modest but real increases in lean mass, strength, and work capacity. Any other form (HCl, ethyl ester, buffered) is unnecessarily expensive.
- Whey protein (20β40 g per serving): Fast-digesting, leucine-rich. Optimal for post-workout muscle protein synthesis. Look for WPI (whey protein isolate) if you're sensitive to lactose.
- Beta-alanine (3.2β6.4 g/day, split doses): Buffers muscle acidity during sets lasting 60β240 seconds. Modest hypertrophy effect via increased training volume.
- HMB (3 g/day): Most useful for untrained beginners and older adults in calorie deficit. Benefits are small in trained lifters.
- Citrulline malate (6β8 g pre-workout): Improves nitric oxide and reduces fatigue. Evidence is mixed but the safety margin is wide.
- Proprietary blends that hide individual doses
- "Test boosters" combined with protein (redundant and underdosed in both)
- Fat burners marketed as muscle builders
- SARMs, prohormones, or anything that sounds like a shortcut β these are often illegal and always unsafe
- Under-dosed creatine (< 3 g/serving)
Ingredient transparency, dose-to-clinical-range match, third-party testing (Informed Sport is the gold standard for competitive athletes), and value per effective serving β not per capsule count.
