Due to the competitive nature of the stevia market, we’re a little shy about our proprietary natural flavor’s formula. Pyure’s natural flavors are USDA Organic Compliant and does NOT include MSG, synthetics, GMO's, aspartame, sucralose, dextrose, saccharin, sugar, soy, animal excretions or bugs… (BUGS? Strange, we know, but yes, ‘bugs’ have been asked about in the past).
