Bulk Calcium HMB for Sports Nutrition

Calcium HMB Overview

Calcium HMB, the calcium salt of beta-hydroxy-beta-methylbutyrate (HMB), has the molecular formula C10H18CaO6, a molecular weight of 274.32 g/mol and CAS registry number 135236-72-5. It is supplied as a white crystalline powder or granular material for sports-nutrition and healthy-aging supplement manufacturing.

HMB is a metabolite of the amino acid leucine that is produced naturally in the body in small amounts. A substantial body of published clinical research shows that HMB supports muscle protein balance, helping to preserve lean mass and accelerate recovery, particularly during resistance training, calorie restriction and the muscle loss associated with aging.

Calcium is the preferred salt form for HMB supplementation because of its stability and established safety profile in food and supplement applications, and it delivers the active HMB moiety at a consistent, documented stoichiometry.

From a procurement standpoint, Calcium HMB is a stable, well-characterized ingredient with no cold-chain requirement, and its defined chemical form supports clean-label positioning in strength, recovery and anti-aging product lines.

Source & Ingredient Identity

Purecium Calcium HMB is produced by a controlled synthetic route with documented starting materials, processed to food grade with an assay specification of at least 98% by HPLC. The product is available as monohydrate and anhydrous powder or granular forms, plus an HMB liquid option for specialized formulations.

Identity is confirmed against reference standards covering chromatographic behavior and calcium content consistent with compendial specifications. Each batch is documented from starting materials through to the finished drum for full traceability.

Powder, granular and liquid formats share the same food-grade release framework, so buyers can qualify one supplier across multiple product formats and simplify their vendor management.

Key Characteristics of Calcium HMB

Key characteristics of Purecium Calcium HMB include its white, crystalline, free-flowing form, defined powder or granular mesh options, and consistent assay and impurity profile. Release limits include heavy metals below lead 0.5 ppm, mercury 0.1 ppm, arsenic 3 ppm and cadmium 1 ppm, meeting EU and USP expectations.

The product is processed with food-grade anhydrous ethanol, with residual solvents strictly below 5,000 ppm in line with USP standards. It is free from major allergens, Non-GMO and suitable for vegetarian and vegan supplement programs, and every batch ships with a Certificate of Analysis.

Physical and chemical data, including solubility, pH, bulk density and sieve analysis, are documented in the product specification sheet, and the powder is stable under standard ambient storage in sealed food-grade packaging.

Consistent particle-size distributions across lots support reproducible blend uniformity and content uniformity in commercial-scale capsule and tablet production.

Calcium HMB Manufacturing

Purecium Calcium HMB is manufactured through a controlled synthetic route in facilities certified under ISO 9001, FSSC22000, Kosher and Halal food-safety programs, with robust, scalable production capacity that supports stable long-term supply for large contract manufacturers.

Production covers synthesis, salt formation, purification, crystallization, drying and granulation to the target form. In-process checks, documented cleaning and changeover procedures, and batch numbering provide full traceability and consistent batch-to-batch quality.

Applications of Calcium HMB

In sports nutrition, Calcium HMB is used in strength, recovery and body-composition products. Published clinical research indicates HMB helps reduce exercise-induced muscle damage and support gains in lean mass and strength during resistance training, making it a core ingredient in performance and recovery formulas.

For healthy-aging and clinical nutrition positioning, HMB supports muscle preservation in aging adults, including those experiencing age-related muscle loss, and in individuals beginning new training programs or managing calorie-restricted phases.

Calcium HMB performs well in capsules, tablets, stick powders and effervescent formats, and it combines readily with protein, amino acids, creatine and vitamins in multi-active sports and wellness products.

The powder and granular forms support standard blending and direct-use filling processes, while the HMB liquid option serves beverage and liquid-shot applications where a soluble format is preferred.

Manufacturing & Quality Control

Quality control for Purecium Calcium HMB operates under ISO 9001, FSSC22000, Kosher and Halal certified food-safety systems. Every lot is released only after identity confirmation, HPLC assay, heavy-metal analysis, residual-solvent testing and microbiological examination against the stated specification.

Analytical methods are aligned to current USP-NF and European Pharmacopoeia compendial methods, and environmental monitoring supports reliable release testing across batches. Finished lots carry a Certificate of Analysis, SDS and specification documentation, with stability data supporting standard ambient storage.

Retained samples and complete batch records are maintained for each production lot to support customer audits and regulatory inquiries, and buyers may request facility documentation during supplier qualification.

Microbiological quality is controlled against acceptance criteria for nutritional ingredients, covering total aerobic microbial count, yeast and mold, and specified pathogens, with environmental monitoring supporting consistent release testing.
