evidence for glucosamine

Our honest take

The best-value way we sell to try glucosamine on its own: two capsules give 1,500 mg of glucosamine sulphate, the dose used in research, for about 20p a day. There is nothing else in it, which we see as a plus. The honest catch is that large independent trials found little benefit over a dummy pill for most people and there is no authorised health claim, so give it around three months and stop if you notice no difference.

You want to try glucosamine at the studied dose for the lowest cost
You do not want chondroitin or other extras
You are allergic to shellfish (glucosamine from crab and shrimp shells)
You take medicine for diabetes, glaucoma or blood thinning, or are pregnant: check with your doctor first
You are vegetarian (gelatin capsules): NOW or Doctor's Best vegan glucosamine suit you better

The science

Glucosamine· evidence: Limited

Glucosamine is a building block of cartilage. In supplements it comes as glucosamine sulphate or glucosamine hydrochloride, usually made from crab and shrimp shells, or from fermented corn in vegan versions. N-acetyl glucosamine is a related form with even less research behind it.

It has been studied a lot, and the results are disappointing. Large independent trials, such as the US GAIT trial, and a big review of the research found little or no difference from a dummy pill for most people. Some earlier trials using one branded glucosamine sulphate looked better, but many of those were funded by the maker. NICE does not recommend glucosamine on the NHS, and EFSA rejected a claim that it helps keep joints healthy.

There is no authorised health claim for glucosamine, so we make no claims about what it does. If you want to try it, the dose used in studies is 1,500 mg of glucosamine sulphate a day, and it is fair to stop after about three months if you notice no difference.

Typical dose: Studies used 1,500 mg of glucosamine sulphate a day

Safety: Most glucosamine is made from shellfish: avoid unless the label says it is from a non-shellfish source if you have a shellfish allergy. Glucosamine may strengthen the effect of warfarin, so speak to your GP or pharmacist first if you take warfarin or another blood thinner. Speak to your GP first if you have diabetes, asthma or glaucoma, or are pregnant or breastfeeding. Can cause mild stomach upset.
