The Muscle Longevity Stack

Building muscle for longevity requires different priorities than bodybuilding:

  • Creatine monohydrate - 5g daily, the most studied performance supplement
  • Protein - 1.6-2.2g per kg body weight daily, prioritizing leucine-rich sources
  • Omega-3 - completely protective against muscle size loss during immobilization
  • Vitamin D3 - optimal levels support muscle function and recovery

Common Mistakes

  1. Underdosing protein. The range on record is 1.6-2.2g per kg body weight, far more than most people eat.
  2. Wasting money on BCAAs when you are already meeting protein targets. The leucine in complete protein sources is enough.
  3. Using collagen as your primary protein source. It's low in leucine, which makes it a poor protein for building muscle.
  4. Supplementing without progressive resistance training. No supplement replaces the stimulus of heavy compound movements.
