the standardized extract is the real deal....the ones I got have hawthorn extract (141mg per cap) which is standardized to 1.8%/2.5mg of vitexin. also in each cap is regular old hawthorn berries at 424mg per cap. so they are about 500 or so mg per cap with a mix of standardized and berry. I take 6 of them a day when on a harsh PH and it actually keeps BP relatively in check. If anything you might hit the bottom of high normal, but usually you'll be on the high end of normal, not in high normal. When not on harsh PH's? it will keep you way low, REALLY effective. But make sure to get the EXTRACT/standardized version....not some random berry powder....
