The Best HMB Supplements to Buy

Which are the best HMB supplements? 

Beta-hydroxy-beta-methylbutyrate, or HMB for short, is found naturally in the human body as an active metabolite of the amino acid, leucine.

Without getting too technical, HMB reduces muscle protein breakdown while supporting muscle protein synthesis. 

In layman’s terms, if you’re lifting weights regularly and include HMB in your supplement stack, then you may gain more protein than you’re losing, provided you also eat a healthy diet. 

So, to make things easy for you, we’ve rounded up the best HMB supplements on the market right now, so all you have to do is pick your favorite, follow its recommended serving guidelines, and start making those HMB gains! 

Here’s a list of the 10 best HMB supplements.
