Astragaloside IV is generally considered to be the primary active ingredient in Astragalus extract, an herbal extract which has been famous for literally thousands of years for its anti-aging properties.
We recommend at this time that our customers do not use this product for longer than one year.
Purity - 98%
The purity of our current batch of Astragaloside IV is roughly 98%, almost five times higher than anything else available retail in the world.
* See explanation of purity test result along with a record of all our recent batches here.
Lower purities are sometimes coupled with exagerated claims of enhanced bioavailability. In fact the bioavailabilities are almost identical, but the effects of high daily doses of impurities are unknown.
HPLC Tested... and More
Our raw material has been HPLC-tested at an independent US Lab.
But because HPLC testing is only as good as the 'standard' against which it is compared, and particularly because in our opinion a reliable, reproducible and widely accepted HPLC analytical method has yet to evolve in the industry for Astragaloside IV, our samples are further tested periodically using NMR.
NMR is a technique which directly analyzes the structure of the Astragaloside IV molecule by comparing the relative positioning of the (in this case, using H-NMR) hydrogen atoms in the tested material against what is known to be the structure of the Astragaloside IV molecule.
The testing was done by an independent lab based in the United States. In our opinion if you do not at least periodically supplement HPLC testing for Astragaloside IV with NMR or Mass Spectrometry, than it is difficult to know if you have an Astragaloside IV molecule on your hands. Here you can see our NMR results and
analysis on the A60 batch.
Light Resistant Capsules
Our capsules are light-resistant which means the molecule stays in tact on our shelves and yours.
Health and Safety
