what is pyrroloquinoline quinone disodium salt
Abstract. The potential use of pyrroloquinoline quinone disodium salt (BioPQQ™), as a supplemental food ingredient, was evaluated in a range of oral toxicity studies in rats including an acute study, a 14-day preliminary and a 28-day repeated-dose study, and a 13-week subchronic study.QQ disodium salt is also currently authorized in Canada as a Natural Health Product, providing 20 mg PQQ disodium salt/d as an antioxidant for the maintenance of good health (Health Canada, 2012).
