To date, laboratory testing has not been able to detect any amounts of soy protein in our products. We use Essential Phospholipids (EPL), which are made from the highest quality non-GMO soy lecithin. Virtually all of the soy protein, which is of allergic concern to some individuals, is removed from the EPL during the extraction process. While we cannot guarantee our products do not contain trace amounts of soy protein, we routinely conduct DNA testing on each product with an independent laboratory. To date, the laboratory has not been able to detect any amounts of soy protein in our products.
