Comparing Leucine To HMB

Comparing Leucine To HMB HMB, a metabolite of the Branched Chain Amino Acid (BCAA) leucine, is used by hard-training athletes for muscle recovery. A recent study published in the Journal of Physiology compared HMB's effect on muscle anabolism to the support that supplementation with leucine provides.

Subjects consumed 2.42 grams of pure HMB or 2.42 grams of leucine. Both increased anabolic signalizing, stimulated muscle protein synthesis and enhanced muscle anabolism. The effects were similar with both supplements.

True Strength Moment: One capsule of ON's HMB contains a gram of Hydroxy Methylbutyrate, so if you took one after training and another stacked with your nighttime casein shake, you'd be getting pretty close to the 2.42 grams used in this study. The casein shake is also going to provide anti-catabolic support with essential amino acids.
