Really works!

Posted by Reviewer1447906 on Jan 24, 2011

This is the best product for boosting one's immune system. I take one daily and several a day when I feel like I'm coming down with something. My two young boys get sick a lot and I almost never do and if I do get something, it's only mild. I contribute all to Olive Leaf Extract!

Helps lessens the the duration of cold/flu

Posted by Reviewer1581590 on Mar 06, 2012

My whole family caught the flu recently and I was the only one who took 2 caps of Olive leaf extract 3 times a day. I was the first to recover. Everyone else had to get on antibotic (which didn't help) and other over the counter meds. I think this is a very beneficial product for the immune system

Good for immune support

Posted by ALoren on Sep 28, 2013

I take it to support my immune system whenever I feel like I'm coming down with a cold or flu. Its supposed to be able to fight not only viruses, but also bacteria, fungi and even protozoa.

Immunity from flu

Posted by Reviewer1660870 on Nov 19, 2012

I found this product by snooping through the profiles of smart iherbers with a similar condition to mine (CFS). I've bought this here for the last, 2+ years and have not had the flu. A flu attack could drop my already low energy to barely bearable levels. I don't want that. So I take 3 of these a day and don't get the flu.

Es un extracto potente y muy efectivo. Mi madre tomaba diuréticos para la hipertensión y con estas cápsulas los ha podido dejar, la tensión se le ha puesto normal y está súper contenta. Genial.

Good cold fighter

Posted by 5234728829999803621 on Apr 12, 2016

Helped a lot with fighting against viruses. Had to be taken with the first signs of cold 3-5 times per day, after that one-two for maintenance. Also good against candida. This is the good side. On the other hand it started to interfere probably with my thyroid (I am autoimmune hyper thyroid, still on remission). As I searched afterwards, its active component, hydroxy thyrosol may interfere with thyroid hormones - T3 and T4. The influence was rather mild but I still stopped taking olive leaf. At the same time it may be a suitable remedy for hypo thyroid people. No bad side effects.
