The typical Recommended Dietary Allowance (RDA) of HMB, or β-Hydroxy β-Methylbutyrate, is approximately 3 grams per day. HMB is a metabolite of the essential amino acid leucine and is well-known for its potential benefits in muscle preservation, particularly in individuals engaged in intense physical training or those who may be at risk for muscle loss, such as older adults or critically ill patients.

Research has indicated that 3 grams per day is an optimal dose to elicit positive effects on muscle protein synthesis and recovery, making it a commonly recommended intake for performance enhancement and recovery strategies. Higher dosages, while investigated, do not necessarily lead to proportionally greater benefits and can increase the risk of adverse effects without providing additional benefits for muscle health or performance. Thus, the understanding of HMB's dosage is primarily grounded in this well-researched range.
