## Description

Product description Over 40% Total Polyphenols Harvest the power of real polyphenols with 500mg olive leaf extract and 50mg olive fruit extract, standardized to high levels of oleuropein, hydroxytyrosol, and synergistic olive polyphenols. Not limited to one famous nutrient. Grown & Extracted in Spain Fresh from traditional family-owned farms in Andalusia, Spain, where sustainable olive production has been a way of life for thousands of years. Most other olive leaf extracts are Chinese, often mislabeled as "made in USA." Made the Right Way Crafted from select varieties of the right tree type ( Olea europaea ), using traditional methods and modern technology , without toxic pest control, herbicide, fertilizer, irrigation, chemical solvents, or synthetic polyphenols. Trusted Since 1995 From American family-owned brand Island Nutrition, maker of premium dietary supplements for over 30 years, specializing in real European Organic Oregano Oil and Olive Extracts. Natural Blood Pressure and Immune Support 100% grown & extracted in the pristine farmlands of Mediterranean southern Spain, known for vibrant health, longevity, and high agricultural standards. This ultra-premium blend of olive polyphenols starts with select non-GMO Spanish olive trees, grown without toxic pest control, herbicide, fertilizer, or irrigation on centuries-old family farms, where some trees date to Roman times. Not all olive extracts are the same. Polyphenol composition depends on the type of olive, growing conditions, season, region, harvest time, extraction method, etc., so it matters where you get your olive extracts. Our olive experts use traditional extraction methods to preserve broad spectrums of synergistic phytonutrients. No high heat or chemical solvents. Just water and organic grape alcohol. Do you know where your olive extract comes from? We do. We have made Real European Olive Leaf Extract for decades, backed by science and centuries-old family farms. Yet, our price per mg of Oleuropein is similar to ordinary mass-market olive leaf extract. Beware of copycats with synthetic polyphenols or toxic ingredients. We do not manufacture for these other olive leaf extract brands. Features 90 capsules per bottle Full-spectrum non-GMO standardized extracts Broad mix of powerful olive polyphenols Premium European herbal supplement Encapsulated & bottled in the US No synthetic polyphenols No fake reviews Trusted US brand specializing in oregano oil and olive extracts

Review: Quality - Great product!
Review: It Works! - Wow! 3 weeks ago my bp was 188/100. I suffer from white coat syndrome and my bp soars if I am anxious, therefore I'm not a candidate for bp meds , as when I'm not stressed my bp plummets dangerously low. I read about olive leaf extract and got the green light from my doctor to take it. It's been 3 weeks since that high reading. I have also begun lowering my sodium and caffeine consumption and increasing my postassium-rich food consumption. I have also adopted the 4,7, 8 breathing meditation. All of these things worked together very well for me. The olive leaf extract made a huge difference. I even bought some for my sister and she is seeing remarkable reduction in her bp readings. The seller contacted me and advised me to start slow with the dosage , as their brand is more potent than most. I thought that was very kind of them. I will not be without my olive leaf extract. It has so many antimicrobial and antifungal benefits, and even helps lower glucose levels in addition to lowering bp. I purchased some earplugs from desertcart to take with me to the doctor to help drown out the bp machine sound that bothers me. The lower readings from the olive leaf has helped me not be so anxious about taking my bp so eventually the earplugs may not be necessary.

## Features

- 40% POLYPHENOLS — Super-strength 500mg Per Capsule (not “per serving”) of olive leaf extract. All 500mg is standardized to at least 25% pure oleuropein and 40% total olive polyphenols.
- 20% HYDROXYTYROSOL COMPLEX — 50mg standardized for other active polyphenols found in extra virgin olive oil, such as Hydroxytyrosol and Tyrosol.
- AUTHENTIC — Made from true Mediterranean olive trees (Olea Europaea), 100% grown and extracted in Spain. Almost every other supplement brand uses cheap Chinese olive leaf, often from the wrong plant or mislabeled as made in USA or made in Spain.
- SUPER-STRENGTH — As much natural polyphenol per capsule as 1/3 liter extra virgin olive oil. Supports health benefits of the Mediterranean diet.
- PREMIUM SOURCE — Harvested on family-run Spanish olive farms. Processed in Spain using traditional extraction (no chemicals). Made by Island Nutrition, maker of premium supplements since 1995.

### ⭐⭐⭐⭐⭐ This stuff works!
*by M***R on October 4, 2018*

I can only tell you of the personal results that I have had. Every person's body is unique and what worked almost miraculously for me may not work for you. I have spinal stenosis. I have a horrible time getting up from a seated position and my balance and ability to walk without stooping is an issue. A few weeks after starting this my friends and my class noticed that I can easily get up and I can now walk just barely holding onto my walker! I still have very bad knees but my back pain has decreased by 70%. Seriously! When the bottle warns you about not taking it with blood pressure meds, they mean it. My blood pressure plummeted. I quit taking my lisinopril and I've been taking my blood pressure 2x a day and it is on the low range of normal now! I quit eating sweets, but also my blood sugar readings have also dropped. I have fibromyalgia and although I still get flares and sensitivities, the brain fog has dramatically decreased and the fatigue isn't nearly as bad. I can't take any medications for fibro. One gave me a stroke and another made me so ill I couldn't move. This extract has something that my messed up body evidently is craving because the results for me have been dramatic. With my energy, increased mobility and less brain fog for the first time in literally years I can go out of my house for something other than essential chores. For me this extract has been life changing.
