Glucosamine products are some of the most popular nutritional supplements in the UK and there are numerous research studies supporting their use. Healthspan were the first company in the UK to launch an alternative shellfish-free glucosamine HCl, which we call Optiflex. This is a concentrated, shellfish free supplement that, weight for weight, supplies 40 percent more glucosamine that the traditional glucosamine sulphate 2KCl form. It is also a far more sustainable source as well as being suitable for vegetarians. Overall, an ideal form of glucosamine for everyone!
