For joints? Or is it just a myth that it will help?
Last time used to read about glucosamine , but personally i think train the muscles around the joints would be a better way. Glucosamine is expensive if i am not wrong. Take stuff like Centrum -multi vitamins, i think 1 day like 30 or 50 cents.
Try some joint supplements like Nutrtion joint, i used to have a knee cap problem but its okay now
