iHerb Customer Reviews

Would give 5 stars if this came in Veg Capsules. Will switch to Thone Research, Olive Leaf, Oleuropein 18%!!

My pharmacology books say Big Hard Gelatin capsules may get stuck in Esophagus. Olive Leaf works like an ACE inhibitor for blood pressure. So I order Thorne although it is VERY expensive. I wish I knew what is the Biological Half Life T1/2 of this Olife Leaf 'medication'.

Good quality product

Posted by HealthyLiving4Me on Jul 30, 2016

This is a nice product from a brand I haven't used before. I would prefer a higher dose capsule though. I have been using it for a couple of months now during a lot of colds and have found that it has worked well.

Great for Blood Pressure

Posted by Reviewer1587782 on May 10, 2016

This has lowered from pressure to 130/78. I am elated. It acts like a ace inhibor. If you also take it with celery- a big drop. I can't because celery messes up your Thyroid numbers.
