NOW Supplements, PQQ 40 mg with 200 mg Alpha Lipoic Acid, Extra Strength, 50 VegCognitive Support* With 200 mg Alpha Lipoic Acid Mitochondrial Support* GMP Quality Assured: NPA A-rated GMP certification means that every aspect of the NOW manufacturing process has been examined, including our laboratory/testing methods (for stability, potency, and product formulation). Packaged in the USA by a family owned and operated company since 1968 Mitochondria are the parts of the cell that produce energy. While all cells have them, the heart and brain are especially dense with mitochondria due to their high energy demands. Pyrroloquinoline Quinone (PQQ) is a B vitamin-like compound that helps to protect mitochondria from free radicals and promotes the production of new mitochondria within cells.* PQQ may thus help to maintain robust cellular energy production, support heart health, and promote normal cognitive function.* Extra Strength PQQ includes alpha lipoic acid to complement PQQ s free radical scavenging abilities.* This extra strength product has twice the PQQ (40 mg per capsule) as in our regular strength product (20 mg per capsule). Natural color variation may occur in this product. Payment DetailsWe currently accept payment via PayPal only. Once payment is cleared, we will dispatch your shipment within 1-3 business days.
