Introduction A magnesium supplement that passes release testing on day one may not pass at expiry if the stability file was not built for the salt, the format, the packaging system, and the storage and distribution conditions. Magnesium salts differ in how they interact with moisture, which can change flow,

Introduction The same elemental magnesium target does not mean the same raw-material weight, and the same raw-material weight does not mean the same capsule count. Hard-capsule capacity is a volume constraint, not a fixed milligram limit. For development purposes, a size 0 or size 00 shell may accommodate several hundred

Reviewed by KS Nutripharma Director of R&D (PhD, Food Science 19+ years nutraceutical development) Technical review scope: incoming raw-material testing, finished-product release testing, identity versus assay, specification versus COA, multi-salt magnesium, and stability documentation Introduction: Finished-product magnesium is tested against the approved finished-product specification — not against the incoming drum

Reviewed by KS Nutripharma Director of R&D (PhD, Food Science 19+ years nutraceutical development) Technical review scope: raw-material identity, chelation specification, buffered composition, label architecture, and COA review Buffered vs unbuffered magnesium glycinate can share a front name and still be different drums. Do not compare two “magnesium glycinate” quotes
