HMB (beta-hydroxy-beta-methylbutyrate) is a metabolite of the essential amino acid leucine. It is a substance that occurs naturally in the body, and is also found in small amounts in some foods, such as grapefruit and catfish. HMB has been shown to have potential benefits for muscle growth, strength, and recovery.

Research suggests that HMB may work by reducing muscle protein breakdown, which can help to preserve muscle mass and prevent muscle damage during exercise. HMB may also help to enhance muscle protein synthesis, which is the process by which new muscle tissue is created.

Each capsule of Pole Nutrition HMB contains 1 gram of pure HMB. This dosage is in line with the dosages used in many studies that have investigated the effects of HMB on muscle growth and performance. However, it is important to note that the optimal dosage of HMB may vary depending on individual factors such as body weight, exercise intensity, and training status.
