Joint Glide Supplement Facts: Every Line on the Panel
Every line as printed, plus our own recalculation of all four percentages.
The Joint Glide panel lists a serving of two capsules and 30 servings per container.
It declares vitamin B6 0.5 mg, magnesium 100 mg, zinc 10 mg and copper 2 mg, then devil's claw 500 mg, MSM 300 mg, glucosamine hydrochloride 200 mg, pine bark extract 150 mg, white willow bark extract 150 mg and black pepper extract 10 mg. Other ingredients: cellulose (vegetable capsule) and olive oil.

The panel as a table
Four rows with percentages, six with a figure and a double asterisk, and no total hiding anything.
| 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 |
| Glucosamine Hydrochloride | 200 mg | Daily Value not established |
| Pine Bark Extract (Pinus massoniana) | 150 mg | Daily Value not established |
| White Willow Bark Extract | 150 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.
The footnote** Daily Value (DV) not established.
Other ingredientsCellulose (vegetable capsule), Olive Oil.
Marks printed on the label itselfNon-GMO · Soy Free · Lab Tested. The Soy Free mark is a real allergen statement. There is no shellfish statement, and glucosamine is commonly manufactured from shellfish.
We recalculated all four percentages
A printed percent Daily Value is a claim about arithmetic, and arithmetic can be checked. So we checked all four against the FDA's published Daily Values rather than taking them on trust.
Vitamin B6: 0.5 mg against a Daily Value of 1.7 mg is 29.4%. Printed as 29%. Correctly rounded.
Magnesium: 100 mg against a Daily Value of 420 mg is 23.8%. Printed as 24%. Correctly rounded.
Zinc: 10 mg against a Daily Value of 11 mg is 90.9%. Printed as 91%. Correctly rounded.
Copper: 2 mg against a Daily Value of 0.9 mg is 222.2%. Printed as 222%. Correctly rounded.
Four out of four. It is the second label on this desk to manage that, and the first to manage it alongside a complete set of botanical amounts.
Because a wrong percentage is the cheapest possible tell that nobody checked the panel before it went to print. Finding four right ones tells you something real about the people who produced it.
Six things this panel gets right, and one it does not
Tab through them. Each is a line the regulation asks for, and five of the six are answered properly.
Serving size
Simply take 2 capsules each morning with 8 oz of water and a few bites of food.
Two capsules is one serving, and there are 30 servings in a 60-capsule bottle. So a bottle is exactly thirty days, and every amount on the panel is the amount two capsules deliver.
Amounts printed
Four nutrients with a percent Daily Value, and six further ingredients each with a milligram figure and a double asterisk for Daily Value not established.
There is no proprietary blend on this label. That is the single most unusual thing about this product, and it is the reason this site can do arithmetic that the other sites on this desk cannot.
Percentages
We recalculated all four: B6 0.5 mg against a 1.7 mg DV is 29.4%, printed as 29. Magnesium 100 mg against 420 mg is 23.8%, printed as 24. Zinc 10 mg against 11 mg is 90.9%, printed as 91. Copper 2 mg against 0.9 mg is 222.2%, printed as 222.
Four for four, every one correctly rounded.
Standardisation
Pine bark extract is standardised to 95% proanthocyanidins and black pepper extract to 95% piperine. Both are printed on the panel.
The two that are not are the two that most need it: devil's claw is a powder with no harpagoside figure, and white willow bark has no salicin figure — and salicin is the compound behind every caution on our safety page.
Other ingredients
Other Ingredients: Cellulose (vegetable capsule), Olive Oil.
Two items, and that is unusually short. A plant capsule shell and one carrier oil, with no magnesium stearate, no silicon dioxide and no microcrystalline cellulose filler. The shell being cellulose is why the vegetarian mark on the listing is supportable.
What is missing
No storage instruction, no caution panel, no age restriction and no distributor address appear on the label images we were given.
They are the only real gaps on an otherwise exemplary panel, and on a product containing willow bark the absent caution panel is the one we would most like to see filled.
The forms, which the panel did not have to print
Look at the bracketed text beside each mineral, because that is where a formulator's decisions show.
Vitamin B6 (as pyridoxal 5’-phosphate). This is the activated form, the one the body uses directly, rather than plain pyridoxine hydrochloride. It costs more and is not required to be disclosed in that detail.
Magnesium, zinc and copper (as amino acid chelates). Chelates rather than oxides. The NIH notes that magnesium in the aspartate, citrate, lactate and chloride forms is absorbed more completely and is more bioavailable than magnesium oxide, which is the cheap default this product did not use.
Pine bark extract (Pinus massoniana) (std. to 95% proanthocyanidins). A species and a standardisation, both printed.
Black pepper extract (fruit) (std. to 95% piperine). The plant part and the standardisation.
Organic devil’s claw powder (Harpagophytum procumbens) (root). Species and plant part, though no marker percentage.
None of that detail is required. All of it was printed. It is the most informative thing on the label after the amounts themselves.
The footnote, and what the double asterisk is doing
The panel prints: ** Daily Value (DV) not established.
That mark sits against the six botanical and compound ingredients, which is correct: no Daily Value exists for devil's claw, MSM, glucosamine, pine bark extract, willow bark extract or piperine, so there is no percentage column to fill for them.
It is worth being precise about what this does not mean. Daily Value not established is a statement about reference intakes, not about evidence, and not about safety. An ingredient can have a large and well-conducted literature behind it and still have no Daily Value, because Daily Values are set for nutrients rather than for botanicals.
It also does not excuse a missing amount, and on this label it does not have to: every one of those six carries a milligram figure beside the asterisk. On most labels in this category the same six would sit inside a proprietary blend with one total between them.
The four things this panel does not carry
A caution panel. No warning block, no age restriction and no pregnancy statement appears on the label images we were given. On a product containing a salicylate source, this is the gap that matters.
A storage instruction. Nothing about temperature, light or moisture.
A shellfish statement. The label carries a Soy Free mark, so allergens were considered. Glucosamine is commonly manufactured from shellfish and nothing addresses it.
An address for Critical Nutrition Labs. The manufacturer is named on the front of the bottle, which is more than most manage, and no street, town or contact is printed with the name.
Four omissions against a panel that gets almost everything else right. We would rather list them precisely than let them cancel the rest of the page.
Ten things this label does not tell you
- A harpagoside percentage for the devil's claw. It is the largest ingredient at 500 mg and the marker the research is usually expressed in, and the panel gives a powder weight only.
- A salicin percentage for the white willow bark. Salicin is the compound behind every caution on our safety page, and 150 mg of extract does not tell you how much of it there is.
- A caution panel. No warning block, no age restriction and no pregnancy statement appears on the label images we were given — on a product containing willow bark.
- A storage instruction. Nothing tells you what to keep it at or away from.
- A shellfish statement. Glucosamine is commonly manufactured from shellfish, and the label carries a Soy Free mark but nothing about shellfish either way.
- An address for Critical Nutrition Labs. The manufacturer is named on the front and no street, town or contact is printed with it.
- Any price. Pack prices are whatever the info page shows at checkout.
- The name of the doctor behind the Doctor Formulated badge. No clinician is named anywhere in the material we were given.
- Any test report or laboratory name behind the Lab Tested mark on the label, or behind certificate reference JOI-3366-26-TH.
- Any verified customer reviews, and any expiry date. The material we were given contains a review block that its own source note marks as layout copy.

The Joint Glide Supplement Facts Panel: common questions
Is it true that every ingredient has a printed amount?
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.
Why does it matter that there is no proprietary blend?
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.
Are the printed percentages correct?
All four. We recalculated each against the FDA's published Daily Values: vitamin B6 0.5 mg against 1.7 mg is 29.4%, printed as 29; magnesium 100 mg against 420 mg is 23.8%, printed as 24; zinc 10 mg against 11 mg is 90.9%, printed as 91; copper 2 mg against 0.9 mg is 222.2%, printed as 222. Four for four, correctly rounded.
Do the forms of the minerals matter?
They do, and this label chose well. The B6 is pyridoxal 5'-phosphate, the activated form, rather than plain pyridoxine hydrochloride. The magnesium, zinc and copper are all amino acid chelates rather than oxides — and the NIH lists magnesium oxide among the least well absorbed forms. None of that is required to be printed, and all of it was.
Are the extracts standardised?
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.
What exactly is in it?
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.
222% of the Daily Value for copper — is that safe?
2 mg is a fifth of the 10 mg tolerable upper intake level the NIH gives for adults, so the percentage looks large mainly because the Daily Value is small at 0.9 mg. It is also there for a reason: the NIH notes that excessive zinc supplementation can lead to copper deficiency, and this formula carries 10 mg of zinc. Pairing them is the correct decision.
I have a shellfish allergy. Can I take it?
Ask the order desk before you buy. Glucosamine is commonly manufactured from shellfish, and this label carries a Soy Free mark but says nothing about shellfish either way. It is the one allergen question the label does not answer and it is a specific, answerable question.
