Quality & Testing
Third Party Lab Testing
Each batch of our product undergoes rigorous and detailed third party lab testing, to make sure our ingredients are consistently of the highest quality and meet the best of international standards. We test for purity, heavy metals, solvents, pesticides, and bacteria. We strive to give our customers confidence, and in full transparency, we make the results available below.
Ultra-High Purity
Our Fermented Purple Corn Extract is a potent source of natural anthocyanins. Our purity levels are greater than 99%, ensuring our commitment to bringing you as high-quality of a product as possible. These purity levels are further confirmed by third party lab tests.
30:1 Extract Ratio
Our Fermented Purple Corn Extract utilizes a potent extraction processes at a 30:1 extract ratio, meaning that a single, 1,000mg serving of our Purple Corn Extract is equivalent to 30,000mg of standardized purple corn powder.
Glyphosate Free
Glyphosate is a very common pesticide, and we make sure not to use any in the growing of our purple corn. This is further confirmed by third party lab tests.
Consumption Safety
Research has shown that oral supplementation of purple corn extract and anthocyanins is safe and well-tolerated by the body. Given that natural anthocyanins have been ingredients of approved drugs for over 30 years, their high level of safety is supported by long-term extensive pharmaco-vigilance.

Natural Compounds
More than 20 bioactive phenolic compounds (natural molecules from plants), including phenolic acids, anthocyanins, and other flavonoids have been found in purple corn. These phenolic compounds have been shown in numerous in vivo and in vitro studies to have potent health-benefitting capabilities.
Vegan
Our product is 100% vegan and plant based, including our capsule shell, made of glutinous rice starch (which is gluten free) and is easily digested and absorbed by the body.
GMO Free
Our product is free of genetically modified organisms (GMOs).
Gluten Free
Our Purple Corn Extract is gluten free.
GMP Certified
Our manufacturing facilities are GMP (Good Manufacturing Practice) Certified. GMP is a system for ensuring that products are consistently produced and controlled according to quality standards. It is designed to minimize the risks involved in any food or pharmaceutical production.
ISO 9001 Certified
Our manufacturing facilities are ISO (International Organization for Standardization) 9001 Certified. This is an internationally recognized quality management system (QMS) standard that demonstrates the ability to consistently provide products and services that meet customer and regulatory requirements.
ISO 14001 Certified
