Another beautiful product by the global health institute. I love quercetin and I started using it as a form of protection from the shedding off people who had the shots. I will always take quercitin, it's a fantastic antioxidant and this is a beautiful plant version. Very bioavable, there's nothing I don't love from Dr Group and Dr Henry Ealy etc you're guaranteed highly clean , high quality supplement's . I'd highly recommend this to anyone . I take the three tablets as recommended always .
