PQQ is a supplement that is not discussed very often but is critical if you want improved energy, better sleep, reduced stress and enhanced memory - due to the first three benefits. PQQ acts as a vitamin-like compound in the REDOX process within mitochondria. This process controls the amount of energy these "power supplies" are able to produce, so having more PQQ available in your body improves the amount of energy you can produce. PQQ also protects mitochondria, which it does in two main ways: by maintaining mitochondrial mass and stimulating their regeneration. Meaning not only will they perform for you better, and give you more energy in every cell in your body, but also stop them from degenerating - plugging any energy leaks your body might have already that is giving you a sense of fatigue or low energy.


Pure Nootropics PQQ provides 20 mg per 1 capsule. Suggested use for adults is 1 capsule by mouth daily with a meal.If you are taking any medications, always consult with you Healthcare Practitioner before beginning any new supplement.
