We take pride in knowing that we bring you the most potent, purest AFA in the world. The benefits of Aphanizomenon flos-aquae (AFA) are directly related to the care and attention given to sourcing, harvesting, and drying of the product. E3's quality care begins with the selection of the freshest AFA blooms. The AFA is selectively gathered by expert harvesters and collected from only the deepest, most pristine waters of Upper Klamath Lake. We harvest only at peak times of optimal growth when the AFA is the heartiest and most vibrant. The harvesting is quickly followed by rapid chilling and is further purified. Our E3Live and E3AFA products are handled more expeditiously from harvest to freezer than any competitive product. Their quality control parameters, coupled with their proprietary final processing, yield the lake's most potent source of AFA Hydro Dri (also known as Refractance Window) drying technology is a proprietary drying method that uses a heat transfer process and specific properties of water to gently remove moisture while maintaining the maximum integrity of the natural material. Hydro Dri technology retains nutrients, enzymes, color and taste far better than freeze drying and “fresh air (Bio-Active dehydration)” drying. How is the consistent quality of E3 products assured? From the moment we harvest the AFA, to its final packaging, we work with only the most highly trained and qualified staff. We handle our AFA with such care from start to finish. Factors contributing to this quality include: where and how we harvest, keeping the AFA cold at all times, superior filtration and storage, and ongoing quality-control testing of all of our products. All E3 products are tested thoroughly by independent USDA certified labs for food safety, shelf-life and various other purity tests. No additives or preservatives. Gluten free, Dairy free.
