FIT Food^® Lean Collagen features bovine collagen peptides complemented with beta-hydroxy-beta-methylbutyrate (HMB) and vitamin D3, making it an optimal choice for supporting collagen production, the integrity of connective tissues, and muscle health. A natural metabolite of leucine, HMB increases lean muscle mass through dual mechanisms: inhibiting protein degradation and promoting protein synthesis. This versatile formula rapidly disperses in water and is ideal for athletes or for individuals who need an easily digested protein source.*
