    PQQ (Pyrroloquinoline Quinone)

    With lunch

    Pyrroloquinoline quinone (PQQ) is a redox cofactor naturally present in soil, interstellar dust, and small amounts in foods like natto, parsley, and green tea. It has gained attention for its potential to stimulate the creation of new mitochondria and protect existing ones from oxidative damage. PQQ is not classified as a vitamin but acts as a powerful antioxidant at the cellular level.
