🧪 Formulation Notes

Mitochondria are the organelles that produce almost all of the cellular energy the body requires. While present in all cells, organs like the heart and brain are particularly dense with mitochondria due to their high energy demands. Pyrroloquinoline quinone (PQQ) is a B vitamin-like enzyme cofactor that helps to maintain the integrity of mitochondrial structures and promotes the generation of new mitochondria within cells. PQQ may thus help to maintain robust cellular energy production, support heart health, and promote normal cognitive function. CoQ10 and Acetyl-L-Carnitine have been included for their critical roles in mitochondrial function and energy production.
