Aren't They All The Same?

Purple corn extracts are commercially available today; however, there are variations to specifications and not all companies are capable of providing exact data (eg. information on exact origin and specific anthocyanin types). It is important to note that because not all purple corn have the same levels of antioxidant properties, hence not all commercial purple corn extract give rise to the same therapeutic outcomes. To make matters more confusing, not all published values on specification sheets make for apple-to-apple comparisons due to the difference in test protocols adopted. It is important to note that established regulators such as South Korea's FDA (MFDS - Ministry of Food and Drug Safety) does not approve the use of “UV-VIS” method for analysis as it is deemed to be neither accurate nor consistent enough for measuring anthocyanin levels, amongst other factors. Yet most commercial powder extract uses the UV-VIS method for analysis without disclosing test protocols.


So What Does "Validated Grade" Mean?

Consumer trust in functional nutrition is vital for both the industry’s and consumers' long-term success. With that goal in mind, we have invested in improving processes and protocols to ensure Purity, Safety, Quality and Potency for our GU3G™ Purple Corn Powder Extract product. With our Validated Grade range, we are elevating consumer confidence to new levels:

The GU3G™ Difference

GU3G™ is produced using a proprietary efficacy-boosting technology that increases the concentration of C3G in the body when orally administered. Our GU3G™ Anthocyanin and C3G values (as published below) are derived from liquid chromatography techniques in accordance with Korea FDA (Ministry of Drug and Food Safety - MFDS) guidelines.
