THE MOST ACTIVE FORM OF QUERCETIN: Toniiq Quercetin Capsules contain 1000mg of the highest quality quercetin powder in each capsule– ethically sourced, grown and cultivated using an extraction process to ensure 95% standardized purity (most quercetin 500mg and quercetin 1000mg extracts contain 70% or less). Higher purity quercetin means higher absorption and bioavailability.* A KEY ACTIVE INGREDIENT: Quercetin has amazing health benefits, but purity has always been a major challenge for this flavonoid; something most other quercetin supplements don’t provide as it requires an extra step (and expense) in the manufacturing process. At 95% standardization, Toniiq Quercetin provides the purest, most potent quercetin extract available. SETTING A NEW STANDARD FOR PURITY: To ensure that you are getting a high quality quercitin supplement, each batch is tested for quality and purity both during and after manufacturing. Each lot is additionally tested for solvent residues, heavy metals, pesticides, and toxins.
