No proprietary blend. Every ingredient carries a figure, which means every figure can be checked.
Joint Glide lists ten ingredients, each with a printed amount per two-capsule serving.
They include organic devil's claw 500 mg, MSM 300 mg, glucosamine hydrochloride 200 mg, pine bark extract 150 mg, white willow bark extract 150 mg, magnesium 100 mg and zinc 10 mg. There is no proprietary blend.
Four rows with percentages, six rows with a figure and a double asterisk, and nothing hidden behind a total.
| As printed on the panel | Amount per 2-capsule serving | % Daily Value |
|---|---|---|
| Vitamin B6 (as pyridoxal 5’-phosphate) | 0.5 mg | 29% |
| Magnesium (as magnesium amino acid chelate) | 100 mg | 24% |
| Zinc (as zinc amino acid chelate) | 10 mg | 91% |
| Copper (as copper amino acid chelate) | 2 mg | 222% |
| Organic Devil’s Claw Powder (Harpagophytum procumbens) (root) | 500 mg | Daily Value not established |
| MSM (methylsulfonylmethane) | 300 mg | Daily Value not established |

| Black Pepper Extract (fruit) | 10 mg | Daily Value not established |
There is no proprietary blend. Ten dietary ingredients are declared and every one of them carries a figure. That is the only time this desk has been able to write that sentence about a product, and it is why the rest of this site can do arithmetic instead of guessing.

Chosen because they are the ones that change how you read the rest of the label.
The heaviest ingredient in the capsule, printed with its species and plant part. It is a root powder rather than an extract and no harpagoside percentage is given, so it cannot be matched to the trial literature by marker content. It is also the one ingredient the brand's own marketing panel leaves out.
The ingredient this site flags hardest. Aspirin derives from salicin, and Sloan Kettering warns against willow bark with warfarin or other blood thinners, with NSAIDs, in aspirin sensitivity, and in children because of Reye syndrome. No salicin percentage is stated.
Glucosamine trials generally use 1,500 mg a day. This is 200 mg. NCCIH also notes that studies of prescription glucosamine sulfate showed more favourable results than those using other formulations, and this is the hydrochloride.
The best-specified line on the panel: species named, amount printed and the standardisation stated. Pine bark extracts are commonly studied around 100 to 200 mg a day, so this one can actually be compared with something.
A large percentage of a small Daily Value, and well under the 10 mg upper limit. It is paired with 10 mg of zinc, and the NIH notes that excessive zinc can lead to copper deficiency — so including copper alongside zinc is the correct call.
Methylsulfonylmethane, printed with its full chemical name. Knee osteoarthritis trials have generally used 1.5 to 6 grams a day, so 300 mg is well below the studied range. The label prints the number and lets you draw the conclusion.

What this label printsWhat the research usedper two-capsule serving, log scale
Every dietary ingredient on this label carries a printed amount and there is no proprietary blend. That is what makes a comparison possible, and the comparison is not flattering: glucosamine at about an eighth of a trial dose and MSM at roughly a fifth. Both of those criticisms exist only because the label was honest enough to print the numbers that produce them.
The six botanicals first, then the four nutrients. Scroll or use the arrows.
500 mg · the largest ingredient
First by weight, and the one the brand's own marketing panel leaves out entirely. It is a powder rather than an extract, and no harpagoside percentage is stated — which is the figure the research is usually expressed in.
300 mg · a fifth of a common trial dose
Methylsulfonylmethane. Trials in knee osteoarthritis have generally used 1.5 to 6 grams a day. 300 mg is well under the bottom of that range, and the label does not claim otherwise — it just prints the number and lets you check.
200 mg · 13% of a studied dose
The usual dose in glucosamine trials is 1,500 mg a day. This is 200 mg, so about one eighth. NCCIH also notes that studies of prescription glucosamine sulfate showed more favourable results than those using other formulations — and this is the hydrochloride.
150 mg · inside the studied range
The best-specified ingredient on the label: 150 mg of <i>Pinus massoniana</i> bark, standardised to 95% proanthocyanidins. Pine bark extracts are commonly studied at 100 to 200 mg a day, so this sits inside that band and the standardisation lets you check it.
150 mg · the one to ask about
Willow bark contains salicin, from which aspirin was originally derived. Sloan Kettering warns against it with warfarin or other blood thinners, with NSAIDs, in aspirin sensitivity, and in children because of Reye syndrome. No salicin percentage is stated.
10 mg · standardised, and doing a job
Standardised to 95% piperine. Piperine is the compound used to improve the absorption of other ingredients, so a small, standardised amount here is a formulation decision rather than a filler. It is the second of the two extracts on this label that state what they are standardised to.
0.5 mg · 29% DV
As pyridoxal 5'-phosphate, the activated form, which is a more expensive choice than plain pyridoxine hydrochloride. 29% of the 1.7 mg Daily Value.
100 mg · 24% DV
As an amino acid chelate rather than the oxide. The NIH lists the oxide among the least well absorbed forms, so this is the better of the two common options, at a quarter of the 420 mg Daily Value.
10 mg · 91% DV
As an amino acid chelate, at 91% of the 11 mg Daily Value. Comfortably under the 40 mg tolerable upper intake level for adults.
2 mg · 222% DV
222% of a 0.9 mg Daily Value, and under the 10 mg upper limit. It is there for a reason: the NIH notes that excessive zinc supplementation can lead to copper deficiency, so a zinc formula that includes copper is doing the sensible thing.
Under 21 CFR 101.36(c) a proprietary blend declares the total weight of its dietary ingredients and lists them in descending order of predominance by weight. Individual amounts are not required. It is legal, it is extremely common, and it is the single most frequent reason a supplement cannot be evaluated.
This label has none. Every one of the ten dietary ingredients carries its own milligram figure, which is why the chart above can be drawn at all.
That has three practical consequences. A pharmacist can assess an interaction by dose rather than by name. A buyer can compare an amount against the research. And a reviewer can say something specific instead of describing the marketing.
It also means the product exposes itself to criticism that a blended competitor would escape. The glucosamine here is 200 mg against the 1,500 mg used in most trials, and everybody can see that. A product hiding the same 200 mg inside a 1,150 mg blend would look better and be no better at all.
Every criticism on this site exists because the label was transparent enough to permit it. That is not a reason to go easy on the criticism, and it is a reason to prefer labels that invite it.
Front of the card: what it is and the amount this label prints. Tap it over for the named source and the exact words.
A standardised extract states what proportion of it is the compound the research is about. That figure is what turns a weight of powder into a comparable dose, and most labels in this category carry none at all.
Two of the six botanicals here carry one, printed on the panel. Pine bark extract is std. to 95% proanthocyanidins. Black pepper extract is std. to 95% piperine. Both are real, checkable specifications.
The four that do not are MSM and glucosamine hydrochloride — which are single defined compounds, so the question does not really arise — and, more importantly, devil's claw and white willow bark, which are the two where it matters most.
Devil's claw is 500 mg of root powder, the largest ingredient in the capsule. The trial literature on devil's claw is usually expressed in harpagoside, and no harpagoside percentage is stated, so the weight cannot be converted into a marker dose.
White willow bark is 150 mg of extract with no salicin percentage. Salicin is the compound that makes willow bark aspirin-like and it is behind every caution on our safety page. Without a percentage, the exposure cannot be estimated.
Those two omissions are the real gap on an otherwise exemplary panel, and it is worth being precise that they are omissions of specification rather than of amount.
Read as groups rather than as a list of ten, the design intent is clear.
Glucosamine hydrochloride and MSM, the two staples of this category. Both are here at amounts well below the doses used in trials, which the label prints honestly.
Devil's claw, white willow bark and pine bark extract. Two of the three are traditional pain botanicals; the third is an antioxidant extract at a dose inside its studied range, and the only one of the three you can compare with anything.
Vitamin B6, magnesium, zinc and copper, all in the better forms, with copper included because zinc can push it down. Black pepper extract at 10 mg is there to help the rest get absorbed.
It reads, in full: Other Ingredients: Cellulose (vegetable capsule), Olive Oil.
Two items. That is short enough to be worth remarking on. Most capsules in this category list four or five excipients — magnesium stearate, silicon dioxide, microcrystalline cellulose, sometimes a colour — and none of those appear here.
Cellulose as the capsule shell is a plant material, which is what makes the vegetarian mark on the listing supportable from the printed label rather than only from a badge.
The olive oil is a carrier, which is a slightly unusual choice for a powder-filled capsule and suggests the fill is at least partly suspended rather than loose. The label does not explain and we are not going to speculate further.
One question this line does not answer: glucosamine is commonly manufactured from shellfish, and there is no shellfish statement anywhere on the pack. The label carries a Soy Free mark, so allergens were clearly considered. That makes the omission more surprising rather than less.
Every ingredient name, amount and percentage on this page is transcribed from the printed Supplement Facts panel supplied with the product images, read at native resolution. Every claim about evidence is attributed to a named source in the reference list, and every one of those sources is a page we opened ourselves.
Yes, and it is the reason this site reads differently from the others on this desk. Four nutrients carry a milligram figure and a percent Daily Value; six further ingredients carry a milligram figure and a double asterisk for Daily Value not established. There is no proprietary blend anywhere on the label. Ten of ten.
Because a blend declares one total weight for several ingredients and hides the individual amounts, which is legal under 21 CFR 101.36(c) and is the single most common reason a supplement cannot be evaluated. Without one, every figure on this label can be compared with published research — including where that comparison is unflattering, which on this product it sometimes is.
Per two-capsule serving: vitamin B6 0.5 mg, magnesium 100 mg, zinc 10 mg, copper 2 mg, organic devil's claw powder 500 mg, MSM 300 mg, glucosamine hydrochloride 200 mg, pine bark extract 150 mg standardised to 95% proanthocyanidins, white willow bark extract 150 mg, and black pepper extract 10 mg standardised to 95% piperine. Other ingredients: cellulose (vegetable capsule) and olive oil.
Two of the six are, and both say so on the panel: pine bark extract to 95% proanthocyanidins and black pepper extract to 95% piperine. The four that are not include the two that most need it — devil's claw, where harpagoside is the marker, and white willow bark, where salicin is the compound behind every caution on our safety page.
We do not know. It is the largest ingredient in the capsule at 500 mg — more than the next two combined — and the brand's own Inside Joint Glide graphic shows five ingredients without it. The printed panel is the authority here and we follow the panel. Worth adding: it is a root powder rather than an extract and no harpagoside percentage is stated, so its weight cannot be converted into a marker dose.
It is about an eighth of the dose used in most trials, which is typically 1,500 mg a day. We are not telling you that makes it useless, because the evidence for glucosamine at any dose is contested — NCCIH reports a 2018 analysis of 29 studies finding pain significantly reduced by glucosamine taken separately, while the ACR and OARSI guidelines recommend against use. What we can say is that this is well below what the studies used, and that the only reason you can know that is that the label printed the number.
This is the most important safety line on the site. Aspirin was originally derived from salicin, the active compound in willow bark. Memorial Sloan Kettering warns: do not take it if you are taking warfarin or other blood thinners, because willow bark may increase the risk of bleeding; avoid combining it with NSAIDs; avoid it in aspirin sensitivity, asthma, breathing problems or stomach ulcers; and children should not be given willow bark because of the potential for Reye syndrome. No salicin percentage is stated on this label.
