Source Naturals Activated Quercetin Bioflavanoid Complex is a 50-capsule seasonal-support supplement designed to help inhibit histamine release with quercetin and complementary ingredients.
Seasonal changes can make it useful to have a supplement formulated around histamine-release support alongside broader immune, respiratory, and antioxidant support. This complex combines quercetin with three additional ingredients in capsule form. Its suggested directions also account for people with a delicate or easily irritated stomach, who are advised to take the capsules with meals.
Source Naturals Activated Quercetin is intended for seasonal support, with quercetin helping to inhibit histamine release. The formula also provides immune, respiratory, and antioxidant support through its combination of ingredients. These are support purposes, not claims to diagnose, treat, cure, or prevent a disease.
Alongside quercetin, Source Naturals Activated Quercetin contains bromelain, magnesium citrate, and vitamin C. Bromelain is a pineapple enzyme; these additional ingredients are included to activate and optimize quercetin’s benefits while contributing to the formula’s broader support purposes. The product name identifies it as a Bioflavanoid Complex.
The suggested use is 3 capsules 1 to 2 times daily, taken in divided doses between meals. If you have a delicate, easily irritated stomach, take the capsules with meals instead. Follow these directions when planning how the 50-capsule quantity fits your routine.
