Each Batch is Individually Tested - We test each batch both ourselves and through a third-party independent laboratory to ensure our ingredients contain the correct standardized level of purity and active ingredients. We also test each batch for any possible additives, contaminants, and impurities to ensure the highest level of quality. Quality, First, and Foremost - Toniiq products are produced in a GMP-certified and NSF-approved state-of-the-art manufacturing facility in the USA. Setting a New Standard for Purity - To ensure that you are getting the highest-quality product, each batch is tested for quality and purity both during and after manufacturing. 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% purity levels, Toniiq Quercetin provides one of the purest and most potent quercetin extracts available. The Highly Purified Form of Quercetin - Toniiq Quercetin Capsules contain 1000mg of the highest quality quercetin powder in each serving– ethically sourced, grown and cultivated using an extraction process to ensure 95% standardized purity (other quercetin 500mg and quercetin 1000mg extracts contain 70% or less).
