Formulation Notes

Nature's Lab Quercetin with Bromelain is a potent combination containing 800 mg of quercetin and 200 mg bromelain to promote immune, antioxidant, and inflammatory health. Quercetin belongs to a class of water-soluble plant substances called flavonoids. Acting as a natural antioxidant, quercetin promotes cell health, healthy ageing and general wellness. Quercetin may also act as an anti-histamine to support a healthy inflammatory response as well as a healthy immune response. Bromelain is a group of enzymes found in the fruit and stem of the pineapple plant. These enzymes aid in the breakdown of proteins in the body to promote a healthy inflammatory response, immune health and general wellness. Additionally, bromelain works to promote absorption of quercetin in the body.
