Gaspari Nutrition's HMB 1000mg is a specialized supplement aimed squarely at supporting athletic performance and muscle physiology. It delivers a robust 1000mg (1g) dose of HMB (Calcium Beta-Hydroxy-Beta-Methylbutyrate Monohydrate), which is an empirically effective amount for mitigating exercise-induced muscle damage, reducing protein breakdown, and potentially accelerating muscle recovery and growth. While the HMB compound naturally contains 130mg of calcium, this amount is ancillary and far from sufficient to fulfill daily calcium requirements for adults, nor does the product include critical co-factors like Vitamin D3 for proper calcium absorption and bone mineralization. Therefore, this product's primary utility and value are almost exclusively tied to its benefits for fitness and muscle management.
