Immune Support and Allergy Relief

Both Quercetin and Luteolin have wide-ranging effects that support immunity and provide relief to allergy sufferers. These flavonoids stabilize mast cells to regulate histamine release, support immune cell function, and promote healthy inflammatory response, especially in the respiratory tract.*

Cognitive Support and Neuroprotection

Provides antioxidant protection, neutralizes free radicals, supports brain and nerve health, and calms glial cells to enhance mental clarity, mood, and stress tolerance.*

NAD Support

Quercetin and Luteolin are two of the most potent inhibitors of the NAD-depleting enzyme CD38. This helps maintain NAD+ levels, supporting mitochondrial function, energy, and overall health.*

Longevity Supplement

Quercetin and Luteolin work together to reduce cellular senescence, up-regulate sirtuins, and provide antioxidant support, all which support healthy cellular aging.*
