Good Product
Customer—November 7, 2025
Been taking it for a while now and it seems to help with blood circulation. I've tried other brands, but prefer this one which does not have a lot of other fillers. Read more

Great Product but with caution
xdolf—December 21, 2025
I think it is a great product--but would suggest that if someone is on blood thinners, they should use caution and check with their doctor. Read more

Seems to be helping. Full strength?
Earl W. Roethke—September 24, 2025
I've been taking this about a month, and my cardio is easier now than a month ago. I hope this is helping. I did see a review that indicated that when tested, these capsules didn't have the full 4000 FU promised. I would appreciate hearing from the manufacturer if these test results are accurate.
