β-Hydroxy-β-methylbutyrate free acid reduces markers of exercise-induced muscle damage and improves recovery in resistance-trained men

Randomized Controlled Trial
Human
2013 Aug 28

The study gave trained men a specific supplement (HMB-FA) before a tough workout and found their muscle damage markers went up much less than in those who took a fake pill — exactly what the claim said would happen.

Similar Assertions

Taking a specific supplement called HMB-FA before a tough workout might help slightly reduce muscle damage in guys who regularly lift weights, but the evidence isn’t strong enough to say for sure it works.

Taking a specific supplement called HMB-FA before a tough workout doesn’t make you lift more weight or change your starting strength — so if you feel better or recover faster, it’s probably because of the supplement itself, not because you worked out harder.

Taking a specific supplement called HMB-FA before a tough workout doesn’t change your hormone levels or inflammation markers the next day, at least not in guys who regularly lift weights.

After a tough leg workout, a blood marker of muscle damage (CK) spikes by more than 1.5 times and stays high for two days, showing the muscles are still healing.
