Description
Supplement First is an Authorized Retailer for Douglas Laboratories.
- Douglas Laboratories Muscle Protect with HMB provides a leucine-rich blend of essential amino acids combined with HMB®, vitamin D3 and glutamine for muscle maintenance.
- Leucine, a branched-chain amino acid, has an anabolic role in muscle protein synthesis and may specifically benefit aging adults by preserving healthy muscle mass and function.
- ß-Hydroxy-ß-methylbutyrate (HMB) is a metabolite of leucine that supports lean muscle mass through two unique mechanisms: decreased muscle degradation and increased protein synthesis. Vitamin D and glutamine provide additional support for muscle health.‡
