How we compare joint supplements

Last updated: November 4, 2026

Every comparison on MyJointLab follows the same written process, so readers can check our work. We are an independent affiliate publisher, not a manufacturer, retailer, or medical provider.

1. What we look at

• The label: ingredients and amounts per serving, taken from the Supplement Facts panel published by each brand or major retailer.
• Dose per day: how many capsules or tablets a day the label asks for, and how long one bottle lasts.
• Price per day: the listed price divided by days of supply on the date we checked. Prices change often; always confirm at checkout.
• Refund terms: the guarantee or return window stated by the seller.

2. How we label evidence

When we mention research on an ingredient (for example glucosamine, chondroitin, MSM or turmeric), we say whether results were mixed, small, or limited. We do not say any supplement treats, cures or prevents a disease, and we do not promise results.

3. What we do not do

• We do not test products in a lab and we do not run clinical trials.
• We do not publish fake reviews or invented testimonials.
• We are not affiliated with or endorsed by the brands we compare. Trademarks belong to their owners.

4. How we make money

Some links go to an offer where we may earn a commission if you buy, at no extra cost to you. This never changes the facts printed on a label. See our Editorial policy.

5. Corrections

If a label or price changed, tell us on the Contact page and we will review and update the page.
