7 Best HMB Supplements of 2023: Uncover the Top Picks for Muscle Growth

best hmb supplements


Best HMB supplements—this phrase might have caught your eye recently, especially if you’re into muscle building. HMB, or Î²-Hydroxy β-Methylbutyric Acid, is a compound that the body naturally produces from the amino acid leucine​​. It’s gaining traction in the fitness community for its potential to enhance muscle growth and performance.

People are turning to HMB supplements for a variety of reasons. The primary allure? It’s believed to accelerate muscle mass gains, reduce muscle breakdown, and promote faster recovery post-training​​. That is why it’s becoming a staple in the regimen of bodybuilders, athletes, and fitness enthusiasts.

Apart from muscle building, HMB has other benefits up its sleeve. It may play a role in reducing muscle wasting in individuals facing health conditions like cancer or HIV/AIDS, and there’s also some buzz about its potential to curb cognitive decline​.

Another interesting aspect of HMB is its contribution to a positive protein balance in the muscle, which is crucial for muscle preservation and growth. By reducing muscle protein breakdown and possibly enhancing muscle protein synthesis, HMB creates a favourable environment for muscles to thrive​.

As we delve deeper into HMB supplements, we’ll uncover more about the top HMB supplement options, how does HMB support muscle growth and address some common questions about this intriguing supplement.

Understanding HMB

What is HMB?

HMB, or Î²-Hydroxy β-Methylbutyric Acid, is a derivative of the essential amino acid leucine. It’s a naturally occurring substance that the body produces from the proteins in our diet. Foods like catfish and alfalfa contain small amounts of HMB. It is a byproduct of the breakdown of leucine, which is one of the building blocks of protein​.

HMB has been shown to help preserve muscle mass in healthy older adults, thus being effective in managing age-related muscle loss, also known as sarcopenia​​.

When Taken By Mouth

HMB is safe when taken by mouth. Doses of up to 3 grams daily for up to one year have been used safely. It’s recommended that individuals adjust their dosage based on body weight, with general guidelines suggesting 2 grams per day for those weighing up to 130lbs and 4 grams per day for those over 130lbs​.

Pregnancy and Breastfeeding

There isn’t enough reliable information to determine whether HMB is safe to use during pregnancy or while breastfeeding. It’s advisable to stay safe and avoid use during these times.


HMB supplements can offer a range of benefits, including:

  • Increased gains in lean muscle.
  • Prevention of muscle catabolism.
  • Speeded up muscle repair and recovery times.
  • Decrease in body fat.
  • Decrease in blood cholesterol levels.
  • Increase in VO2 max and endurance.​

Ineffective for Physical Performance in Older People

While HMB can help preserve muscle mass and strength in older adults, physical exercise may produce similar—and likely more—benefits to improve muscle and strength in healthy older people, especially when coupled with a properly designed exercise regimen​.

How does HMB support muscle growth and performance?

HMB supports muscle growth and performance by minimizing muscle breakdown after training and slowing down proteolysis, the natural process of breaking down muscle tissue after intense physical activity. By doing so, it helps the body recover faster post-training, staying in an anabolic state for longer, which allows for more muscle growth. Moreover, HMB increases protein synthesis while decreasing protein breakdown, creating a favourable environment for muscle growth and strength gains​.

This thorough exploration into HMB sheds light on its benefits, especially towards muscle preservation and growth, and provides a clear understanding of its safety profile and the circumstances under which it should be used or avoided.
