Table notes

  • Only three products in our test would give you 1200mg/day or more of chondroitin sulphate. These figures are highlighted in green in the table.
  • Two products contain significantly less glucosamine than the label claims. These figures are highlighted in pink in the table.

Glucosamine sulphate
Some manufacturers only give the amount per tablet or capsule of glucosamine sulphate potassium chloride complex. In these cases we’ve calculated the amount of glucosamine sulphate.

Measured glucosamine
We measured the amount of glucosamine hydrochloride or sulphate (averaged over 10 tablets or capsules) and compared this as a percentage of the amount claimed on the label.

Cost per maximum recommended daily dose
This is based on the dose recommended on the label and prices we paid in Sydney supermarkets and pharmacies in December 2007. Larger sizes, which could be cheaper, may be available.

(A) Glucosamine made from maize starch.
(B) Glucosamine sulphate sodium chloride complex. Others are glucosamine sulphate potassium chloride complex.
(C) Manufacturer told us its testing gave 98%.
(D) Manufacturer told us its testing gave 100%.
