Olive Leaf Extract Super Strength is rated 4.9 out of 5 by 77.
Rated 5 out of 5 by from Taking for immune system Am taking this to improve my immune system but not sure how to test it...or know whether this is working? Purchased enough until the end of the year and taking with colustrum in hopes of improving my immune system. Hope to get some extra blood work done end of the year to see if immune system has improved since last year.

Rated 5 out of 5 by from Very potent First time I tried one I felt nauseous, it has a strong taste if dissolved in water like I do, the second time I was fine. Overall I can tell that this product is real leaf extract and not a buy product. Only wish they used something else then rice bran.

Rated 5 out of 5 by from VERY EFFECTIVE I use Swanson's Olive Leaf Extract for sever years. It is a wonderful antioxidant also, it detoxify certain organs such as the liver, which I use it for. It's kind of like getting two products for the price of one. Speaking of price, nobody prices are better than Swanson's. Bottom line here is... I'm very satisfaction with this product.

Rated 5 out of 5 by from More Bang for your Buck My husband and I have spent a lot more money on other brands and were quite happy to find that we did not sacrifice quality to save money with this Swansons brand product. We were so impressed that we bought enough to give to our adult children and have just ordered more to add to our shelf.

Rated 5 out of 5 by from need more capsules in bottle I wish swanson's would sell olive leaf extract with more capsules in the bottle. Something like double or triple the amount. I take more than the recommended amount.
