The joint supplement category is crowded, and most comparisons default to cherry-picked ingredient lists without dose math. This comparison applies the same evaluation framework to each product: verified per-ingredient disclosure, dose alignment with published research thresholds, allergen transparency, pricing, and refund terms. Products that do not disclose per-ingredient amounts cannot be fully assessed on dose — and that limitation is documented rather than glossed over. This comparison was built from the Tutela Medical editorial team's verified label analysis and is updated for 2026.

Evaluation Criteria
Every product in this comparison is assessed on six criteria. Ingredient transparency: does the Supplement Facts panel disclose per-ingredient amounts, or does the product use a proprietary blend that obscures individual doses? Dose math: for glucosamine and chondroitin specifically, how does the disclosed amount compare to the 1,500 mg and 800–1,200 mg research standards? Secondary ingredient doses: are other ingredients present at amounts that can be meaningfully compared to any published research? Allergen disclosure: are relevant allergens clearly labeled? Refund terms: what is the guarantee window, and are there conditions that limit eligibility? Price per day at the standard supply tier: what does consistent use actually cost?
JointBrex
Serving: 2 vegetable capsules per day. Price per day at the 3-bottle tier: $1.97 ($177 for 90-day supply). Price per day at the 6-bottle tier: $1.63 ($294 for 180-day supply).
Ingredient transparency: Full. JointBrex discloses all eight ingredient amounts individually on the Supplement Facts panel — no proprietary blend. This allows direct dose comparison to published research thresholds and is the formula's strongest transparency attribute.
Dose math: Glucosamine Sulfate is 1,000 mg per serving — 33 percent below the 1,500 mg research standard. Chondroitin Sulfate is 100 mg — approximately 8 to 12 percent of the 800–1,200 mg research range. Boswellia Extract is 133.3 mg without disclosed standardization. Turmeric is 100 mg of root powder (not standardized extract), yielding approximately 2 to 5 mg of curcumin equivalents. Five of eight ingredients (Quercetin, Methionine, MSM, Bromelain) each appear at 16.7 mg — below any published efficacy research dose for those compounds. For the complete ingredient-level dose analysis, see our JointBrex dose math article.
Allergen: Contains crustacean shellfish (crayfish) — clearly disclosed on label. Individuals with shellfish allergies should consult a physician before use. See our JointBrex safety guide for the full interaction and allergen discussion.
Refund terms: 60-day money-back guarantee from date of purchase. Minimum 30 days of use required for eligibility. All bottles including empty ones must be returned. One-time purchase, no auto-renewal. Processed by BuyGoods.
Who it fits: Adults evaluating a multi-ingredient joint support formula who value full label transparency and a meaningful refund window. The dose gaps in glucosamine and chondroitin are the primary informed-purchase consideration. Full review at JointBrex review 2026.
Move Free Joint Health
Serving: Typically 2-3 tablets per day depending on supply format. Reviewed at our Move Free Joint Health review.
Ingredient transparency: Move Free Joint Health discloses key ingredient amounts including glucosamine HCl, MSM, chondroitin sulfate, calcium fructoborate (Uniflex), and hyaluronic acid. The glucosamine form is hydrochloride (HCl) rather than sulfate — the research base on structural effects in osteoarthritis is more robust for the sulfate form, though HCl studies exist.
Dose math: Move Free Advanced provides glucosamine HCl at doses that vary by product variant. The product line's formulation is positioned for daily maintenance, with dose amounts reviewable from the product label. The inclusion of hyaluronic acid and calcium fructoborate differentiates the formula from standard glucosamine-chondroitin products.
Who it fits: Adults seeking daily joint maintenance who prefer a widely distributed retail brand with established market presence. The glucosamine HCl formulation is appropriate for most users, though individuals specifically looking for the glucosamine sulfate form used in structural research studies should verify form on the label.
Flexomore
Flexomore is an athlete-focused joint support supplement reviewed on this site. The formula includes glucosamine sulphate alongside patented ingredients including Boswellin WS and Tendoforte. The athlete positioning differentiates it from general-population joint supplements. Reviewed at our Flexomore review.
Who it fits: Active individuals and athletes prioritizing tendon and joint resilience support alongside glucosamine and boswellia. The patented ingredient inclusions target a different use case than the general stiffness and mobility positioning of JointBrex.
The Dose Math Decision Framework
For readers comparing joint supplements, two questions answer most of the relevant dose math: How much glucosamine sulfate (not HCl) is in this product, and is it at or near 1,500 mg per day? How much chondroitin sulfate is in this product, and is it at or near 800 to 1,200 mg per day? Products that clearly answer both questions — on the Supplement Facts panel, in disclosed per-ingredient amounts — give readers the information needed to compare against the evidence base. Products that use proprietary blends do not.
For a deeper understanding of what those research thresholds actually mean and what studies produced them, see our glucosamine and chondroitin research guide. For the safety considerations that apply across this category, see our joint supplement safety guide.
Frequently Asked Questions
How does JointBrex compare to Move Free Joint Health?
JointBrex uses glucosamine sulfate at 1,000 mg per serving with boswellia and bromelain. Move Free Joint Health uses glucosamine HCl with hyaluronic acid and calcium fructoborate. The key differences are the glucosamine form (sulfate vs. HCl), the secondary ingredients, and the dose relative to research thresholds. Both products are in the same general category of daily joint maintenance supplements.
What should I look for when comparing joint supplements?
Per-ingredient label transparency (no proprietary blend), glucosamine dose at or near 1,500 mg, chondroitin dose at or near 800–1,200 mg, allergen disclosure, and refund terms with clearly stated conditions.
Is JointBrex worth buying?
JointBrex's full ingredient transparency is a meaningful positive. The dose gaps — 1,000 mg glucosamine versus 1,500 mg research standard; 100 mg chondroitin versus 800–1,200 mg range — are the primary informed-purchase consideration. Whether that formula meets your needs depends on your specific situation and goals. Consult a healthcare provider for personalized guidance.
Which joint supplements use the research-standard glucosamine dose?
The research standard for glucosamine sulfate is 1,500 mg per day. When evaluating any joint supplement, check the per-serving glucosamine amount on the Supplement Facts panel and compare it to that threshold. Products using proprietary blends that do not disclose per-ingredient amounts cannot be assessed on this criterion.
