What is HMB and what does it do?

It’s made when your body breaks down leucine, a branched-chain amino acid (BCAA) that’s essential for protein synthesis and muscle repair ( 1 ). However, your body only produces HMB in small amounts. So, many people take it as a dietary supplement to increase HMB levels in their body ( 2 ).

Is HMB a good supplement?

It appears that HMB does have many positive effects that can lead to increased gain in lean mass and decreased muscle breakdown and is therefore a valuable supplement. So if HMB is a metabolite of leucine, why not just take leucine?

What is the chemical name for HMB?

HMB is a substance that your body produces naturally. It has a few different names, depending on the version of the molecule. It is also known as beta-hydroxy beta-methylbutyric acid, beta-hydroxy beta-methylbutyrate, and hydroxymethylbutyrate.

What is the function of HMB in leucine?

HMB (short for β-Hydroxy β-Methylbutyrate) is a metabolite of the amino acid, leucine. Roughly 5% of dietary leucine gets oxidised into HMB, which is thought to act as an anti-catabolic agent, reducing muscle breakdown (Van Koevering & Nissen, 1992).

What is HMB and how is it formed?

Juhn explains that HMB is a substance formed naturally when the body breaks down the amino acid leucine. Amino acids are the building blocks of protein, and proteins are the building blocks of muscle. To make muscle, your body has to undergo what is called protein synthesis, Juhn says.

What are the benefits of HMB?

The main benefit of HMB it its ability to create a net positive balance of muscle turnover-that’s more muscle building than breakdown. 1 For this reason, taking HMB while also cutting calories for weight loss, can help preserve lean body mass while targeting fat mass.

Is HMB the secret to muscle building muscle?

HMB has not been regarded as garnering much acceptance in the medical literature and amongst sports medicine professionals as being very convincing [for muscle building], Juhn tells WebMD. It definitely does not have very convincing data. Juhn explains that HMB is a substance formed naturally when the body breaks down the amino acid leucine.

What is the function of HMB in leucine?

HMB (short for β-Hydroxy β-Methylbutyrate) is a metabolite of the amino acid, leucine. Roughly 5% of dietary leucine gets oxidised into HMB, which is thought to act as an anti-catabolic agent, reducing muscle breakdown (Van Koevering & Nissen, 1992).

What is HMB in the body?

Technically beta-hydroxy beta-methylbutyric acid, HMB is a chemical that occurs naturally in the body when the amino acid leucine breaks down. Leucine is found in particularly high concentrations in muscles. During athletic training, damage to the muscles leads to the breakdown of leucine as well as increased HMB levels.

What is HMB (beta-hydroxy beta-methylbutyric acid)?

Technically beta-hydroxy beta-methylbutyric acid, HMB is a chemical that occurs naturally in the body when the amino acid leucine breaks down. Leucine is found in particularly high concentrations in muscles.

What is the composition of the HMB supplement?

HMB is a metabolite of L-leucine and is produced in the body through oxidation of the ketoacid of L-leucine (α-ketoisocaproic acid). Since only a small fraction of L-leucine is metabolized into HMB, pharmacologically active concentrations of the compound in blood plasma and muscle can only be achieved by supplementing HMB directly.

Is HMB a stimulator or inhibitor of protein synthesis?

These have identified the leucine metabolite β-hydroxy β-methylbutyrate (HMB) as a potent stimulator of protein synthesis as well as an inhibitor of protein breakdown in the extreme case of cachexia. ...
