    Ubiquinol QH-Absorb - Reduced Form Co-Q10 - 200

    Ubiquinol is the reduced (active antioxidant) state of Co-Q10, the form produced by our cells and is significantly better absorbed as a supplement, particularly as we age. Jarrow FORMULAS® QH-absorb® is a proprietary enhanced stability formula, which has been clinically shown in humans to increase Co-Q10 levels up to 777% (6.14x) over baseline at 300 mg per day intake.

    Ubiquinol QH + PQQ - Supports Heart Health

    Jarrow Formulas® QH+PQQ™ is the powerful combination of QH (ubiquinol) with PQQ (pyrroloquinoline quinone), which is considered by some authorities to be an essential nutrient. QH is the reduced (active antioxidant) state of Co-Q10, the form produced by our cells. It is significantly better absorbed than ubiquinone. PQQ with QH promotes the creation of new mitochondria, a process known as mitochondrial biogenesis.* QH+PQQ™ supports both heart health and cognitive function.*

    Super Ubiquinol CoQ-10 with PQQ - 100 MG
    • Supports heart health
    • Helps inhibit oxidative stress
    • Enhanced mitochondrial support formula
    • Non-GMO and gluten-free

    CoQ-10 is an essential compound that helps power cells in high-energy organs like the heart and liver. However, CoQ-10 levels decline with age, affecting mitochondria function.

    Super Ubiquinol CoQ-10 with PQQ from Life Extension supports cardiovascular health with ubiquinol—the unoxidized, more bioavailable form of CoQ-10—to help inhibit oxidative stress at the cellular level as you age. This advanced formula also includes PQQ to support the creation of new mitochondria and protect existing mitochondrial DNA.
