Food-Based Bioflavonoid Complex.

Quercetin is a bioflavonoid that supports cellular health and function. In human cell culture studies‚ it has been shown to block the manufacture and release of inflammation-causing substances‚ which can help support a healthy immune response to the seasonally changing environment. It also helps promote a healthy cardiovascular system by preserving endothelial integrity and supporting healthy blood glucose levels for those already within normal range. Optimized Quercetin is a proprietary formulation that sets the “gold standard” for high-quality quercetin derived from a food-source blend.

      I bought Optimized Quercetin from Pureformulas.com. My doctor recommended Optimized Quercetin for relief from allergy symptoms since it is springtime. She recommends taking 2 caps three times a day for 2 weeks for a loading dose then one a day after that.

      Pros

      Great product

      Cons

      no dislikes
