NOW Glucosamine, MSM and Arnica Liposome Lotion is a soothing, fast-acting lotion specifically formulated to support normal joint function. This unique blend of ingredients helps to nourish joint tissues and provides components your body can use to maintain normal joint structures. Glucosamine supports healthy cartilage formation, while MSM is a source of organic sulfur, an element that is essential to normal connective tissue production. Arnica is well known for its traditional uses. This product's active ingredients are delivered in Liposomes. Liposomes are very similar to the different layers of the skin barrier and combine well with cell membranes. Due to their mimicking ability, the core ingredients of the liposome can merge more easily with the skin's natural barrier layers, allowing the active ingredients to penetrate effectively.
