I am thinking about taking Astragalus, but need info. There is a $20 bottle that says it has 500 mgs of astragalus extract (0.5% hydroxy-3methoxy-isoflavone-7) and then there is a cheap Nature's Way bottle of Astragalus for $3.49 that just says it has 500 mgs of Astragalus root. Is there a difference other than price?
Thanks.
