        Frequently Asked Questions

        What does “NSF Certified for Sport” mean?

        Simple: If it’s not on the label, it’s not in the product. This certification ensures potency of ingredients and that there are no banned substances.

        What is Niagen?

        Niagen is a patented form of nicotinamide riboside, a member of the vitamin B3 family. It promotes the production of NAD+, which is a coenzyme that supports cellular metabolism and energy production.

        What is NAC? 

        N-acetyl cysteine (NAC) is an amino acid and precursor to the antioxidant glutathione. NAC is used to support cellular health.

        What is PQQ?

        Pyrroloquinoline quinoline (PQQ) is a nutrient made by bacteria and is also found in fruits and vegetables. PQQ helps produce new mitochondria, supports cardiovascular health, aids cognitive function, and promotes energy production.
