Which glucosamine - price difference?

[RikkiTikki]

Please can someone explain if it differs in quality? I understand the dosage may affect the price but Savers similar dosage to branded is so much cheaper. Is it still OK and will deliver the same results?

What do you want it for? What results?

"Dietary supplement
Oral glucosamine is a dietary supplement and is not a prescription drug in the United States.[4][6] Glucosamine is marketed as a supplement to support the structure and function of joints, and the marketing is targeted to people with osteoarthritis.[4][6]
Commonly sold forms of glucosamine are glucosamine sulfate,[4] glucosamine chondroitin, glucosamine hydrochloride,[5] and N-acetylglucosamine.[4][3] Of the three commonly available forms of glucosamine, only glucosamine sulfate is given a "likely effective" rating for treating osteoarthritis.[4] Glucosamine is often sold in combination with other supplements such as chondroitin sulfate and methylsulfonylmethane.[citation needed]
Glucosamine, along with commonly used chondroitin, is not routinely prescribed to treat people who have symptomatic osteoarthritis of the knee, as there is insufficient evidence that this treatment is helpful.[7][8]
As is common with heavily promoted dietary supplements, the claimed benefits of glucosamine are based principally on clinical and laboratory studies. Clinical studies on glucosamine efficacy are divided, with some reporting relief from arthritic pain and stiffness, while others report no benefit above placebo.[4][9][8][10]
As of 2015, there is no evidence that consumption of glucosamine by sport participants prevents or limits joint damage after injury.[11]
