20mg Pyrroloquinoline Quinone

Promotes Mitochondrial Biogenesis

Protected B12 5-MTHF Vitamin C

PQQ 20 is a comprehensive formula designed to most effectively deliver the extensive benefits of Pyrroloquinoline Quinone (PQQ). PQQ is a naturally occurring substance that provides protection to our most vital systems and organs, such as the heart, brain, liver and immune system. Its most well-established benefit is its role in promoting mitochondrial biogenesis - the creation of new mitochondria (the vital cellular structure responsible for all energy production). Mitochondrial function directly affects our energy level, as well as our general health and rate of aging. PQQ also provides powerful antioxidant protection that exceeds that of even vitamins E and C. We also deliver a full B-complex including our absorption-protected methylcobalamin (natural coenzyme vitamin B12). Our uniquely comprehensive PQQ 20 offers the comprehensive support required to enable us to best encounter life's daily challenges, along with those of the aging process.

Contains no additives or common allergens Contains no Milk, soy, yeast, corn, wheat, gluten, sugar, fat, cholesterol, color, preservative, common allergens, genetically modified (GMO) ingredients or manufacturing additives.
