- Salt basis (free acid, calcium or potassium salt) stated on the COA.
- Identity confirmed as Garcinia cambogia peel extract, not a whole-fruit powder.
- Loss on drying and ash reported per batch, since HCA grades are hygroscopic.
- Particle size and bulk density agreed for capsule and tablet lines.
- COA, specification sheet and safety data sheet accompany each shipment.
How This Grade Differs
The separately listed 60% HCA grade has a different declared assay. Confirm the HCA method and salt basis, along with moisture, colour and flow requirements, against current batch specifications before substitution.
