I take this as an antioxidant, anti-inflammatory, and antimicrobial. Derived from the olive plant, olive leaves have been used for infections, inflammation, diabetes, and hypertension. A major component of olive leaf, oleuropein (15%), also has lots of other benefits: stops herpes, protects the brain against Alzheimer's and Parkinson's, improves heart health, lowers blood pressure, supports weight management, reduces cancer risk. A must-have in this challenging time. Be healthy!

Olive Leaf Totally Eliminated My Drainage Problem

No kidding this really helps with health - it was recommended by a doctor to take along with Garlic - I have had fewer sinus issues and if I have them they don't usually last very long - I stopped taking Olive Leaf for a month or two because I had run out - I was starting to get sick and feeling badly. Good stuff I don't know a lot about this product, but I take it daily for one reason. It has totally stopped my need to clear my throat every few seconds. I was annoying myself, and I knew I had to be driving everyone else crazy as well. For whatever reason, taking olive leaf immediately fixed the problem.

Another Favorite

Natural Factors is another trusted company from what I read all of leaf extract as a great choice to add to your supplement choice. I use it to help keep my blood pressure in good numbers and also to help protect from viruses that spread around. The capsule is a good size easy to take. The packaging is super pleasing no aftertaste. The dosage is very reasonable and I trust that I get a great benefit, especially during the winter months.

Using it to normalize cholesterine level, would update my review after finishing the bottle and another test.
