, glucosamine produced from a corn base, 2 tablets provides the optimum level, suitable for vegetarians/vegans & shellfish-free, easy-to-swallow taste-free tabletsnature’s best’s glucosamine hci (hydrochloride) is derived from a sustainable corn-based source & it’s the first glucosamine supplement to be made from this food source in the uk making it suitable for vegetarians & vegans as well as anyone suffering from a shellfish allergy. we’ve split the daily dose of 1500mg glucosamine into two glucosamine 750mg tablets so that the tablets are smaller & easy to swallow. furthermore the tablets are coated to make them easy to swallow & made in the uk to gmp standards. glucosamine can either be presented in the form of a sulphate compound or a hydrochloride compound (called hcl) which is the form used in this product. most research has been carried out on the sulphate form & this is the form we normally recommend. however the hcl form contains slightly more glucosamine per gram & in this case has the benefit of being not derived from shellfish. if you’d like help choosing which glucosamine to take please contact our friendly nutrition advisors//aadvice//class= f-brand!important who will be more than happy to help.
