This has helped me avoid or lessen effects of colds. Used to get many colds, now fewer. Up dosage when cold starts, helps me get rid of it faster.

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'.
