“I have found the product has been helpful in my knees remaining pain free. However I noticed that the ingredients have changed since my previous purchase with the vitamin C, Chrondroitin sulphate, Glucosamine sulphate, Methylsufonylmethane and Hyaluronic acid all reduced in quantity with only the Collagen hydrolysate remaining at the same level. If the product does not continue to provide the same effectiveness I will change to another brand.”
