Joint Formulas

They are different ingredients, each named in the ingredient list. Glucosamine, usually as sulphate or hydrochloride, is an amino sugar, chondroitin is normally chondroitin sulphate, MSM is methylsulphonylmethane, an organic sulphur compound, and collagen is a protein listed as hydrolysed collagen or peptides. Joint Complexes combine several of them.

Some labels print the weight of the salt, such as glucosamine sulphate or hydrochloride, and others the amount of glucosamine itself, so check what the line names before comparing two products. Compare the amount per daily serving, which may be several capsules, rather than per capsule or per tablet.

It depends on the formula, and the label states it. The ingredient list names the source of each ingredient and emphasises allergens such as crustaceans, molluscs and fish. Collagen is of animal origin, for example bovine or marine, and a product suitable for vegans says so on the label.
