HMB – short description the HMB supplement is also known under a slightly longer and complicated name – beta-hydroxy-beta-methyl butyrate. It is a short-chain fatty acid produced in the body from the amino acid leucine, which is part of the BCAA branched-chain amino acids necessary for the growth and maintenance of muscle mass. HMB is a preparation resulting from proteolysis, which is a process leading to the breakdown of proteins.

HMB is a preparation that fulfills very diverse functions in our bodies. Hydroxymethylbutyrate is responsible, among others, for the protection of muscle proteins, increase in muscle mass, and increase of muscle strength,

as well as a decrease in unnecessary fatty tissue. Thanks to this, we can include it in the group of anti-catabolic products.

What is HMB for?

According to scientific research, HMB is not a good solution for everyone. It fulfills its functions only for beginners who are just starting their training. HMB is also one of the best supplements for people returning to strength and body sports after a long break.

In this group, there was a significant increase in muscle mass and muscle strength. Fat tissue was also effectively reduced.

In turn, in the case of people who have been leading an active lifestyle for a long time, HMB does not live up to the hopes placed in it. Supplementation with this preparation is unnecessary because it does not bring any benefits for the exercising person. The metabolism of people with more extended training experience and more experience with the sport can cope without it and achieve the intended results.

Effects of using HMB

As mentioned earlier, HMB was taken in the amount of 3 g a day for men and 2 g a day for women can protect the hard-earned muscle mass during the reduction period.

These doses should be divided into two or three smaller ones. It is also worth remembering that the time of day is essential in HMB supplementation. It is recommended to use 0.1 g for every 10 kg body weight in the morning and evening. After training, you should take 0.15 g of the preparation for every 10 kg of weight. 

HMB also leads to an increase in muscle mass and muscle strength. It is worth using this preparation together with creatine, and then the supplement increases its effectiveness.

Increasing the dose is not recommended. It does not lead to better results. In addition, the excess component is excreted from the body along with urine. Its overdose also does not lead to side effects.

It is worth recalling that proteolysis is a process that leaves behind undigested debris. To prevent transformation into harmful compounds, it is recommended to use probiotics at the same time.

HMB preparations are endogenous chemicals. It is challenging to provide such ingredients in food, so supplementation is essential. Little presence of HMB is found in grapefruit, alfalfa, and some fish. Hydroxymethyl butyrate is produced in the body in small amounts as a protective substance that alleviates the effects of stress associated with exercise, starvation, and body injuries.

The combination of HMB with creatine

Even better results from using hydroxymethyl butyrate can be achieved when using it with creatine and arginine. In the assortment of stores, there are often ready-made mixtures that lead to more favorable results. HMB preparations should be combined not only with creatine but also with beta-alanine and citrulline.

Side effects of using HMB

The preparation has no side effects. Even large doses do not adversely affect the body, and its excess is excreted in the urine.
