“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.

What the Supplement Facts panel says
| Calories | 10 |
|---|---|
| Total Carbohydrate | 2 g |
| Vitamin D | 50 mcg |
| Vitamin D | 2,000 IU |
| Sodium | 20 mg |
| Glucosamine HCI | 1,500 mg |
| Glucosamine HCI | 1.5 g |
| Joint Shield 5-LOXIN Advanced® | 100 mg |
| Boswellia serrata Extract (resin) | we could not read this line |
| Chondroitin/MSM Complex | 275 mg |
| Chondroitin Sulfate, Methylsulfonylmethane (MSM) | not stated separately |
The label groups several ingredients under “Chondroitin/MSM Complex” and publishes only the combined total, so there is no way to tell how much of each one a serving contains. That is the manufacturer’s choice, not a gap in our reading.
Printed on the package: 5-LOXIN Advanced · Free of Gluten · Non-GMO · #1 Pharmacist Recommended Brand · FSA · HSA
We read 11 lines from the package photograph. It is our transcript of the label, not the manufacturer’s panel, and it may be incomplete.
