Chondroitin/MSM Complex publishes one combined total, not its individual ingredient doses.
Rebuilt from public sources on July 22, 2026 · evidence availability is not a safety or effectiveness verdict.
The panel lists “Chondroitin/MSM Complex” as a combined amount. A blend total can’t tell you whether any single ingredient reaches a dose used in research.
Specific fact confirmed
USPTO lists Rexall Sundown, Inc. (['CORPORATION', 'SOCIÉTÉ ANONYME (SA)']) in ['FLORIDA, USA', 'SWITZERLAND'] for the exact brand wordmark. This identifies the USPTO mark owner or applicant; it does not by itse…
The listing-image panel publishes 8 separately quantified rows and 1 combined blend total. Ingredients inside a blend do not have separate amounts.
| Panel row | Amount | %DV | What to notice |
|---|---|---|---|
| Chondroitin/MSM Complex | 275 mg | — | |
| Total Carbohydrate | 2 g | — | |
| Glucosamine HCI | 1,500 mg | — | |
| Glucosamine HCI | 1.5 g | — | |
| Joint Shield 5-LOXIN Advanced® | 100 mg | — |
FDA rules (21 CFR 101.36) require the amount of each dietary ingredient per serving unless hidden in a declared “proprietary blend” (legal, but a transparency yellow flag). A label stating no amount at all is non-compliant — a checkable red flag. This panel states amounts; the open question is whether those declared amounts are independently verified and how they compare with relevant research.

This is the USPTO owner of the brand wordmark. It tells a shopper who is behind the brand, but does not by itself identify the manufacturer or prove where this product was made.
Review counts rose gradually. Written-review counts rose from 942 to 948 across the observed period. That describes count movement, not review authenticity or product quality. A variation family may share some public counts.

The summary stops at product-specific facts. The full report preserves every source, calculation, limitation, and unresolved check for review or sharing.
Confirmed evidence
These checks found support in the public record. They confirm specific facts, not the product as a whole.
Label #30802 “Osteo Bi-Flex Joint & Bone” (Osteo Bi-Flex), entered 2014-02-26, with the full Supplement Facts on file — see the panel below.
USPTO lists Rexall Sundown, Inc. (['CORPORATION', 'SOCIÉTÉ ANONYME (SA)']) in ['FLORIDA, USA', 'SWITZERLAND'] for the exact brand wordmark. This identifies the USPTO mark owner or applicant; it does not by itself prove who manufactures or sells this product.
UPCitemdb resolves 030768196080 to "Osteo Bi-Flex Glucosamine Chondroitin with Vitamin D Joint Health Supplement 1" (Osteo Bi-Flex) — consistent with this listing.
Documented concerns
These are documented contradictions or claims that need more evidence. They are separate from missing data.
Unresolved public record
We looked for these signals but could not settle them from public sources. A gap is not a strike.
We read the full Supplement Facts panel from the listing-image panel (below), but the label doesn’t state a serving weight, so the arithmetic can’t run. A gap in the label’s information, not evidence of a problem.
The paid catalog links this exact item to a parent listing. Review counts on public product pages may be shared across sizes, flavors, or other variants, so the count history is listing context — not evidence that reviewers received or tested this exact variant.
Exact-listing history records written-review counts from 942 on 2026-01-28 to 948 on 2026-07-03 (net +6). Count movements can reflect sales, listing variants, collection resets, or moderation; this history does not establish whether reviews are authentic.
What to ask and check
Ask the brand or seller
Which specific study supports this claim — and was it run on this exact formula?
Ask for the citation, how many people took part, the dose used, and whether the study tested this product or just one ingredient in it. Ingredient research is not product evidence.
Where are the ingredients sourced, and where is the product manufactured?
“Made in USA” can describe only the final bottling step. Ask which country the actives came from and whether the facility is audited.
What is the amount of each ingredient inside the proprietary blend?
A blend total tells you nothing about whether any single ingredient reaches a dose used in research. Brands may decline — that answer is informative too.
Most brands and sellers publish a contact route. A clear answer adds evidence to the record; no answer leaves the question open.
Check for yourself — no one’s permission needed
Compare the panel on the bottle in your hand to the one shown in this record.
Ours was read from listing photos and can contain reading errors. The physical label is the source of truth — if they disagree, tell us and we’ll correct the record.
Scan the barcode on the package and confirm it reads 030768196080.
A mismatch between the barcode on the box and the one on the listing is worth pausing over — it can indicate a different variant, a repack, or a counterfeit.
Check the lot number and expiry on the bottle against any COA you’re given.
A certificate that doesn’t name your lot doesn’t describe what you’re holding.
These are the open questions on this specific record — not a warning about the product, and not a suggestion to buy or avoid it. Getting them answered is how you decide for yourself.
