Mega Flex is a high potency formula designed to nourish and support connective tissue for healthy, flexible joints and comfortable movement. The formula features glucosamine sulfate, a critical precursor of synovial fluid and a necessary nutrient for rebuilding cartilage and improving joint function. Research studies at leading institutions have shown that glucosamine sulfate has a low molecular weight, thus enabling it to easily penetrate the villa of the small intestine and be utilized by the articular cartilage tissue.
