More than just a glucosamine product, Glucosamine QCV is a unique formula developed by Lamberts to provide a full 1000mg glucosamine sulphate 2KCl, with the added advantage of cider vinegar and quercetin. Cider vinegar has been used for centuries for various health reasons including joint health and there are now whole books on the subject so you will be pleased to learn that we have included the equivalent of a dessertspoon of cider vinegar per tablet. Quercetin is a 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. In fact, when our technical team tried to uncover what the active ingredient might be in cider vinegar, quercetin was a firm favourite. We have added a pure source of quercetin, at a level equivalent to that found in four apples.
