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. Bioavailable - Alpha-Lipoic Acid has amazing health benefits, but purity and absorption have always been a major challenge for this antioxidant; something most other alpha lipoic acid supplements don’t provide as it requires an extra step (and expense) in the manufacturing process. At 99%+ standardization, Toniiq Alpha Lipoic Acid provides one of the purest ALA supplements available. The Highly Purified Form of Alpha Lipoic Acid - Toniiq Alpha Lipoic Acid brings some of the most potent levels of support for glucose metabolism and nerve health on the market. Our 1000mg per serving Alpha Lipoic Acid contains an unprecedented purity level of 99%+ (other Alpha Lipoic Acid products like alpha lipoic acid 600mg won't disclose their purity levels).
