Supplements for Training

This is a continually updated page. If you’re curious about a supplement I haven’t yet covered, feel free to bring it to my attention via the contact form on the About page.

It doesn’t matter if you call yourself a sport climber or a boulderer—if you train, you stand to benefit from the exact same supplements. Effective supplements are particularly worthwhile in the context of training because they compound your gains over time. If today you can hold onto a small rung for half a second longer, tomorrow you will be that much stronger for it… and next year even more so.

  • Highly Recommended means the supplement is well-supported by evidence and has a relatively large effect.
  • Recommended means the supplements is well-supported by evidence but only a minor effect.
  • Optional means the supplement is less well-supported by evidence (and doesn’t have strong evidence against) but could be worthwhile.
  • NOT Recommended means the supplement has strong evidence against its efficacy or provides an undesirable effect.
