Swanson Olive Leaf Extract I've been ordering Swanson Olive Leaf Extract for years. These used to be so good when they were fresh and green. During the last year I've received pills that are not fresh and they are yellow in color. They look and smell stale and are ineffective. I have an older bottle that is much fresher with green pills than the newer bottles with the yellow pills. There is a definite quality control issue here. I was hoping Swanson had addressed this when I placed my last order a week ago but I received more poor quality olive leaf extract pills that I am returning. June 23, 2014
I bought this item years ago My husband , my son and I rely on Olive Leaf extract since reading about it several years ago. i've purchase it and all my vitamins, minerals, etc; from Swanson Vitamins online because it's easy to do so, and we love the savings.; and keep buying it. December 7, 2013
I have used this for years. i just have to trust Swanson Products that they use the highest quality. November 3, 2013

OLIVE LEAF ITS DOING WHAT IT CLAIMS TO DO..I'M ALLERGIC TO SO MANY THINGS..I GO NATURAL June 8, 2013
Great I have been taking this product for seven years and have enjoyed the boost in my immune system. May 30, 2013
Top value Olive leaf extract has never been cheap, until now. Never had it in cap form, and it's really convenient. Great price too. May 26, 2013
olive leaf review I had read that the first couple of times you can feel kinda of ill. I had an extreme reaction. I took it at night before I went to bed and work a couple of hours later very ill. I took it again a couple of days later and the same thing happened. I haven't taken it again. sad I was hoping for better results. I have used this site for years and loved every thing else I have tried. April 10, 2013
Good quality lower dosage I had been taking dosages of 750mg extra strength and it was giving me extreme nausea and headaches. I needed a quality lower dosage and this was the perfect dosage for a quality product. Works exactly as I needed with no nausea or headaches!! This is one you really should start out at lower doses! March 24, 2013
Not thrilled You would be better off taking 2 TBLS of extra virgin olive oil a day. The tarry stools this gave is not worth taking it. August 5, 2012
i take this occasionally to help with boosting my immune system & i really feel that it helps! April 5, 2012
Great product! This product smells great and you can feel the energy 30 min after taking it. Miss one day and you'll know. It is one product that is of great value especially as a 2 for 1 purchase. Thank you Swanson! March 30, 2012
great product I take 2 capsules a day and it really helps my immune system keep me healthy. March 26, 2012
It Works What a great price for this olive Leaf Extract. I have taken olive leaf for several years and was used to paying $15 a bottle so when I saw this product for 1/3 the price I was a little unsure how well it worked. The product is great and works as well as the expensive brands.... Swanson you have won me over!! January 30, 2012
Olive benefits without the oil Each pill is roughly equivalent to the polyphenol content of a full cup of high polyphenol content olive oil. Much of the benefits attributed to olive oil come from the polyphenols, and here you can easily get the polyphenols without any oil. However, it is a relatively large dose, more than you would get from normal olive oil consumption, so don't be surprised if you feel an effect that you wouldn't from normal olive consumption. It took me a couple of weeks to get used to it, but I eventually did. At first it caused me to feel as if I was coming down with something, but now I feel better than ever. September 24, 2011
great value Cost incredibly low, and got one free! August 21, 2011
Olive Leaf (Oleuropein) I take Olive Leaf Extract in hopes to build up my immunity and for gastrointestinal improvement. I have noticed a small difference and have faith in this product. I like that it is standardized to 15% oleuropein. July 29, 2011
Great for intestinal health and skin health! This product works great for what it is intended. May 23, 2011
Great Value! I was so excited to find this product buy 1 get 1 free! The order was shipped quickly and the quality of the product was pleasing! October 16, 2010
Great Product My body is very happy.....and thankful. September 24, 2010
Maintaining cardiovascular health Initial impression is great. Maybe I should have given it 5 leaves instead of 4, but first I want to see if the product's initial benefits in maintaining my cardiovascular health continue. I'm betting they will. March 21, 2010
Wonderful Supplement!!! I purchased Olive Leaf Extract to help boost my immune system, and it certainly HAS delivered. I highly recommend this supplement. January 18, 2010
more upbeat now I had been taking olive leaf from another big manufacturer but the effectiveness was poor. When my wife and I saw that Swanson had olive leaf for a reasonable price we decided to give it a try. What a good decision! The olive leaf was very fresh and we only needed what was suggested on the bottle to get the desired effect. Swanson Olive leaf, what a great product! August 12, 2009
