Magnesium glycinate is in high demand, and so is fake or sub-grade material. This buyer’s guide covers what to check before you sign.
Confirm Chelation, Not Just “Magnesium”
Some suppliers sell magnesium oxide cut with glycine and call it glycinate. A proper chelate shows a defined magnesium-to-glycine ratio on the CoA. Request the chelation method.
Check Elemental Magnesium and Impurities
Spec around 14-15% elemental magnesium and tight heavy-metal limits. We provide USP-grade material with third-party heavy-metal panels.
Traceability Matters for Supplements
If your finished product carries a label claim, your auditor will trace the ingredient back to a manufacturer. Keep the supplier’s declaration of origin on file from day one.
Packaging for Capsule Lines
Request low-dust grades if you run capsule filling; it reduces line clogging. We offer both standard and low-dust presentations.
Buyer FAQ
Is a certificate of analysis enough for a supplement brand?
It is the baseline. Add halal/kosher if your market needs it, plus a stability commitment.
How much sample should I request?
50-100 g lets you run identity, assay, and a small dissolution test without burning budget.
