04 Oct 2017 --- The US Patent and Trademark Office has awarded Florida-based Valensa International two new patents, locking down patent protection for the core ingredients related to the company’s FlexPro MD and FlexPro ES. In clinical trials, these dietary formulations for joint health were shown to be three to five times more effective in relieving joint discomfort than a standard commercial formulation of glucosamine and chondroitin.
