Does the marketing hold up?
The listing says 1,200 mg of chondroitin; the panel says 120 mg. We could not find an explanation for the difference — no blend, extract ratio, compound form or multi-capsule serving accounts for it. You are getting 120 mg of chondroitin per serving. …

Trouble on record?✓No recalls found
“Couldn’t verify” means we looked and found no public proof — not a mark against the product. Most supplement claims cannot be independently verified by anyone, so grey is the normal state of this industry.
