Product Overview
Calcium Beta-Hydroxy-Beta-Methylbutyrate (HMB-Ca) is a specialized metabolite of the essential branched-chain amino acid Leucine. It plays a fundamental role in supporting the natural balance of protein synthesis and degradation within the body.
SRBio HMB-Ca is a premium-grade crystalline powder that combines HMB with calcium to ensure maximum stability and shelf-life. Designed for the sports nutrition and active aging markets, our HMB-Ca offers manufacturers a highly reliable, bioavailable ingredient that supports lean tissue integrity and overall metabolic wellness.

Key Advantages
1. Optimization of Protein Metabolism
HMB-Ca is recognized for its dual-action mechanism: it supports the body’s natural signaling pathways for protein synthesis while helping to maintain structural protein integrity. This makes it an essential component for formulations targeting physical performance and recovery.
2. Enhanced Stability and Solubility
Our Calcium-bound format is significantly more stable and less hygroscopic than free-acid HMB. SRBio HMB-Ca features excellent flowability and rapid dispersion in aqueous solutions, ensuring it remains stable in both dry powder blends and RTD (ready-to-drink) beverages.
3. Support for Healthy Aging
As a key nutrient in the “active aging” category, HMB-Ca supports the maintenance of lean body mass. It is a vital inclusion for nutritional products designed to promote physical independence and vitality in older populations.
Manufacturing Excellence
Advanced Synthesis and Purification
We utilize a highly controlled chemical synthesis process followed by multiple recrystallization steps. This ensures the removal of impurities and results in a clean-label powder with a neutral flavor profile, which is critical for high-dose supplement applications.
