A growing consumer interest in healthy aging drives demand for nutrition to support brain health and cognition. In this space, Mitsubishi Gas Chemical offers a naturally derived and pure source of pyrroloquinoline quinone disodium salt (PQQ). Branded under MGCPQQ, the ingredient is produced through a proprietary fermentation process. PQQ is a naturally occurring antioxidant found in trace amounts in vegetables, fruits, eggs, dairy, meat, and fermented foods. The compound is also present in human and animal tissues, with research finding particularly high concentrations in human breast milk.
