Beta-Hydroxy Beta-Methylbutyrate - metabolite of leucine that reduces muscle breakdown
We rank HMB by price per gram of active ingredient - not by pack size - so a bigger tub with a worse price per dose can't outrank a smaller one that's actually cheaper.
HMB, or Beta-Hydroxy Beta-Methylbutyrate, is a substance the body creates from leucine, which is a specific type of essential amino acid (the building blocks used to make proteins). It is known as a metabolite, meaning it is a byproduct created during the breakdown of that amino acid.
It is primarily used to reduce muscle breakdown. By preventing the body from breaking down muscle tissue, it helps people maintain their muscle mass during periods of intense exercise or illness.
To create the supplement, manufacturers typically start with leucine and use a chemical process to convert it into the HMB form. This resulting powder is then measured and packed into capsules or mixed into flavored powders for sale.
This ingredient is generally mid-range in price. This is because the chemical conversion process required to turn leucine into HMB adds a layer of manufacturing complexity compared to simple amino acid supplements.
| Purpose | Typical studied dose | Evidence |
|---|---|---|
| clinical muscle wasting conditions including AIDS, cancer, bed-rest, and periods of caloric deficits | 3 grams daily (taken as 1 gram 3 times per day, or 38 mg per kilogram of bodyweight) | established |
| athletic performance and muscle mass | 3 grams daily | emerging |
| treatment of sarcopenia and enhancing muscle mass and physical function in elderly patients with hip fractures | 3 grams per day | emerging |
