Most Supplements Are Unnecessary

The supplement industry profits from convincing you that pills and powders are essential. In reality, only a handful have meaningful evidence for muscle growth.

Tier 1: Actually Effective

These have strong evidence supporting use.

  • Creatine monohydrate: 3-5g daily, proven muscle and strength benefits
  • Protein powder: Convenient way to hit protein targets
  • Caffeine: Improves training performance

Tier 2: Potentially Helpful

Some evidence but not essential.

  • Vitamin D: If deficient (common)
  • Fish oil: For those not eating fatty fish regularly
  • Melatonin: For sleep optimization

Skip These

Little to no evidence despite marketing claims.

  • BCAAs (waste of money if eating adequate protein)
  • Testosterone boosters
  • Most pre-workout ingredients except caffeine
  • Fat burners

Conclusion

Creatine and protein powder are the only supplements with strong evidence for muscle building. Everything else is secondary to proper training and nutrition.
