This MSM powder has a chromatographic purity of ≥ 99.8%, as measured by standardized testing methods. Dimethyl sulfoxide (DMSO), a common process-related impurity, is controlled at ≤ 0.1%. Any other individual impurity is limited to ≤ 0.05%, and total impurities are held to ≤ 0.2% across all production batches. Water content is controlled at ≤ 0.1%, which supports long-term product stability during storage and consistent performance during downstream processing. Heavy metal and microbiological limits are set to defined, documented thresholds, aligned with prevailing standards for dietary supplement raw materials used in commercial production.
The standard particle size distribution of this product falls within 40–80 mesh, with customizable particle size options available to match specific customer production requirements. The bulk density of the powder is ≥ 0.65 g/mL. These physical properties are optimized for common industrial supplement production processes, including hard capsule filling, tablet compression and dry powder blending. The consistent particle size and density profile supports uniform ingredient distribution in blends and smooth, uninterrupted processing for commercial batch manufacturing operations.
This USP grade MSM powder is suitable for a range of industrial use cases across the nutraceutical and functional food sectors:
Joint Health Supplements It is widely applied as a key ingredient in joint health and mobility improvement products, including oral capsules, compressed tablets and flavored powder formulations for end consumers.
