Olive Leaf Extract Super Strength 5 5 25 29
Absolutely a great product! This is also the best price I have been able to find. April 28, 2012
great antioxidant. alot of bang for the buck as an antioxidant.Also a great immune system boster. March 28, 2012
the best you can get I was blown away to find that you offer olive leaf extract in this high a potency and at a price that I can afford. I can't even find this strength in my local stores - and if I could, I know they would cost a lot more than this! March 14, 2012
very good, does what I wanted it too. February 29, 2012
Pleasant Surprise I bought this to help support the immune system, and every indication is that it's really doing its job on that count -- although for the record I also take Swanson Lactoferrin concurrently for the same purpose. But the unexpected and pleasant surprise is that the Olive Leaf seems to be providing great support in maintaining healthy sugar metabolism (I doubt that benefit would be attributable to the Lactoferrin).

Best Brand of Olive Leaf Product smells very fresh, keeps my immune system happy, and is the highest potency at a great price I have been able to find. December 23, 2011
Awesome - Does what it needs to I take this for multiple issues. Works for all of them. Just an amazing supplement that works amazing for me! November 29, 2011
Excellent product! I researched Olive Leaf to make sure I was getting strength of the active ingredients in each capsule. This is a potent, standardized extract and is an excellent value. Swanson's please don't change formula or price! One thing I noticed immediately about this is that the aroma is terrific. Smells fresh and just "good." You know it's going to be good for you by the scent, and each bottle consistently always has that fresh aroma. October 16, 2011
Olive Leaf Extract Outstanding product. I can really feel the effects soon after I take this, so I know that it's working! In the preferred 20% oleuropein. February 20, 2011
Great product! I had read several articles on the benefits of Olive Leaf Extract, so decided to give it a try for a couple of different problems. Wow! Awesome results! I couldn't be happier. Highly recommend this product to others and Swanson's price is good too. What more can you ask for? February 15, 2011
Superb Product This is the best Olive Leaf extract that I have ever used. And, I have tried many over the years. It has performed above and beyond all my expectations. I highly recommend this to anyone seeking the most effective extract on the market. February 6, 2011

Great Product, Great Price! This is just one more of the many products that Swanson's put their name on and managed to sell at a great price that works just as well as the other much more expensive brands at other stores. Kudos! April 3, 2010
A best buy in olive leaf extract! This standardized herb is a great addition to the human defense arsenal, a very helpful and beneficial supplement to assist immunity in a variety of ways. February 25, 2010

Excellent Product I started taking an Olive Leaf Extract supplement in spring of 2009 - and I am really impressed with the way how the Swanson's Olive Leaf Extract Super Strenght makes me feel. It seems to have a very positive effect on my cardiovascular health as well as my immune system. The other thing I like about it - it is has a very pleasant scent making it an easy caspsule to swollow... I can highly recommend the product! August 17, 2009
My Best Supplement Ever Wish I had known about this supplement a long time ago. It is excellent and has maintained my cardiovascular health. August 7, 2009
Good Value We find Swanson's super strength olive leaf to be of high quality and it enables us to take fewer capsules than the regular strength. August 6, 2009
#1 Best Product! Olive leaf in 750 mg capsules is one of the best supplements I've ever taken. During winter months I stay healthier. Now I take it all year, and absolutely love this product! :) My energy level is higher and I feel very healthy. I highly recommend olive leaf to everyone. It's a wonderful, high quality product! :) July 26, 2009
It worked for him! After a decade of increasing unsightly fingernail problems on my son, enough was enough. I read articles on Olive Leaf Extract, with at least 15% Oleuropin, and decided to try it. I ordered this product and started him on this at three times the suggested daily dose. After 5 months the problems were gone! Needless to say he is estatic and his self esteem has shot up! February 1, 2008
A great bargain I've been using Olive leaf extract to boost my immunity for years. Swanson's Super strength formula is the best I've ever used. Super effectiveness for less money! It's a win/win product. October 10, 2007
