Why not simply buy Astragalus extracts in a health food store?
TA-65 is a very rare molecule and is not a simple concentration of the Astragalus plant. As mentioned above, it is a single molecule processed to a purity of over 90%. All the thousands of other molecules have been removed. Astragalus extracts can be found in most health food stores, but such products contain little or no TA-65. We tested 4 commonly available Astragalus extracts and none of them contained any measureable amounts of TA-65 (the test assay is accurate to one part per million). Our proprietary production process starts with 3 tons of plant material and ends up with capsules that we guarantee contain 5mg of TA-65. Learn more about our quality standards and testing here.
