Best HMB Supplements in 2023 and Why

HMB, or β-Hydroxy β-Methyl butyrate, is generally used to build, maintain and repair muscle tissue and cells. HMB supplement is highly important to ensure the health of our muscles because its anti-catabolic effect protects the muscles from breaking down. When this happens, you put on muscle mass and you get stronger. 

Why HMB? Even though it benefits a wide range of people, it is particularly significant for athletes and weightlifters to build muscle and improve recovery from exercise. HMB is a product of leucine, an amino acid, and so it can be found in some foods (grapefruit, catfish, alfalfa). However, since only a small percentage of leucine is converted and used as HMB, the amount you would have to eat would be quite large. That’s why a good HMB supplement will prove to be a great addition to your diet for biohacking.

Here’s a list of HMB supplements that you can choose from to suit your specific needs-
