β-hydroxy-β-methylbutyrate (HMB)

What is HMB?

HMB is a derivative of the amino acid leucine and has been shown to protect against muscle loss associated with ageing or disease.1 It does this by slowing down muscle protein breakdown and supporting muscle protein synthesis.2

Benefits of HMB

Helps preserve muscle mass3–5

Attenuates exercise-induced muscle damage6

Supports wound healing*7

*When supplemented in combination with glutamine and arginine.7

Recommended dietary intake of HMB

Studies suggest that the optimal daily dose of HMB is 
3 g.4,8

Sources of HMB

HMB is naturally produced in small amounts by your body during the breakdown of leucine (an essential amino acid).9 HMB is found in small amounts in foods such as avocado, grapefruit, eggs and cauliflower.

The importance of HMB for protecting aging muscles.

From the age of 40 years, we lose around 8% of our muscle mass per decade.10 HMB supplementation has been shown to slow this process by slowing down muscle protein breakdown and supporting muscle protein synthesis.2
