Over the past few years Glucosamine has become a popular food supplement. Although Glucosamine is normally derived from shellfish, CT Plex uses a vegetarian form so that it is suitable for vegetarians and those who are allergic to shellfish. CT Plex combines glucosamine with Vitamins C and B6 along with a number of plant extracts from Rosehip, Grapeseed and Green Tea plus the bioflavonoids Rutin and Quercetin.
