The reason this looks inconsistent is they are using specific standardized extracts for seanol which is not an ACE inhibitor I dont believe.This is not a recommendation but simply an observation but I noticed BLR's new Follidrone 2.0 product claims to have an ingredient that is an natural ACE inhibitor...may be worth further investigation.
Edit: well, on second thought not that interesting

Appears to have a slight lowering of BP but results are inconsistent. Further, if I read correctly, where there was a lowering effect there was also a significant reduction in both BMI and fat ratio. As already mentioned above, losing a little weight will reduce BP...
Dieckol is the one we want. A very stout full spectrum extract or a standardized for dieckol specifically would be much more effective.
Or a mix of the full spectrum and some of the dieckol
My pharm grade ace inhibitor lowers my bp maybe 10 points at low dose.
You would probably have a good result with Hawthorn, Follidrone 2,0 and a strong celery extract.
