What it is
Glucosamine is a building block your body uses to make and repair cartilage. The sulfate salt is the form with the most human trials behind it.
Why people take it
For knee osteoarthritis, trials and systematic reviews show small symptom improvements, mostly for the sulfate form taken daily for months. Separately, people who report taking glucosamine regularly in large population surveys die less often during follow-up — an association that cannot prove cause but has been replicated.
Our verdict
Reasonable bet for creaky knees. The longevity angle is association, not proof.
Structure & class
Amino monosaccharide, precursor of glycosaminoglycans in cartilage matrix. Crystalline glucosamine sulfate is the reference form in European trials.
Mechanism & clinical data
Systematic reviews (e.g. Meng et al. 2023) find small-to-moderate effects on pain and function in knee OA, strongest for crystalline glucosamine sulfate. A 2023 systematisk översikt of cohort studies (King & Xiang) and NHANES analyses associate habitual use with roughly 15% lower all-cause mortality; residual confounding (healthy-user bias) is likely.
Pharmacokinetics
Plasma half-life ~15 hours after repeated dosing; cartilage effects accumulate over weeks.
Dose & forms
What to watch out for
The hydrochloride form has weaker evidence. Often paired with chondroitin, which adds little. Shellfish-derived sources matter if you are allergic.
Where this dose comes from
The trial dose above is our editorial pick from the published human trials for this ingredient. We choose the dose that the best-available studies used on the endpoint most relevant to longevity. The range shows the lowest and highest doses tested in published trials. The landmark studies below are the papers we read to set it. You can click through and check our work.
When new trials publish, our automated sweeps flag them. If a new study materially changes the dose, we update it through editorial review and record the old dose, new dose, and the triggering study in every affected product's recommendation history. The dose is never changed automatically.

EU Court sharpens the bar for botanical health claimsA Court of Justice of the European Union ruling in april 2025 further tightened the requirements for how botanical ingredients (herbs, plant extracts) can be marketed with health claims in the EU, effectively removing much of the flexibility of the on-hold list.

EU report identifies 117 supplement substances as potential health risksThe HoA Working Group on Food Supplements (26 European countries) published its first report evaluating 117 substances used in food supplements. Of these, 65 were assessed as likely novel foods, 6 were already regulated, 34 had insufficient data, and 12 were prioritized for Article 8 restriction under Regulation (EC) No 1925/2006. The 12 priority substances include ashwagandha, curcumin, melatonin, piperine, St. John's wort, coumarin, p-synephrine, maca, holy basil, Melaleuca, black cohosh, and L-tryptophan. The report drew on 1,500 RASFF alerts reviewed between 2017 and mid-2022.

EU Health Claims Regulation adoptedRegulation (EC) No 1924/2006 laid down harmonised rules for nutrition and health claims made on foods, including supplements. Only claims listed in the EU Register of authorised claims can be used. Rejected botanical claims are held in a separate on-hold list.

EU introduces the Novel Food RegulationRegulation (EC) No 258/97 required any food or food ingredient without a history of consumption in the EU before 15 maj 1997 to be authorised before being placed on the market. This is the framework that captures NMN, spermidine as a supplement ingredient, urolithin A, and many other longevity actives.
