Glucosamine QCV is a unique formula developed by Lamberts® to provide a full 1000mg glucosamine sulphate 2KCl, with the addition of cider vinegar and quercetin. Cider vinegar has been used for centuries for numerous health reasons and this product provides the equivalent of a dessertspoon of cider vinegar per tablet. Quercetin is a highly active bioflavonoid that is naturally found in fruit and vegetables, particularly in apples, and is one of the few bioflavonoids that has been used in human studies. We have added a pure source of quercetin, at a level equivalent to that found in four apples. Glucosamine is now one of the most popular supplements in the world and although we are not allowed to say why that is we can say that nothing becomes this popular unless people are happy with it!
