An unexpected benefit... and a warning to those with Type II Diabetes.

Posted by Reviewer1921566 on Feb 21, 2011

I am a type II Diabetic with severe insulin resistance. I am also a physician. I have noticed that I need much less insulin when I take the olive leaf extract. It seems to act as an insulin "sensitizer". For those who are diabetic, a warning to monitor your glucose closely once you begin this product to avoid becoming hypoglycemic. An adjustment may be needed in your daily regimen. On the plus side, less shots is a good thing and combine it with some exercise and you may find yourself using 1/2 to 1/4 of your dosage.

Olive leaf is used to fight colds and flu, yeast infections, and viral infections such as Epstein-Barr disease, shingles and herpes. It has been shown to reduce low-density lipoproteins (LDL), or bad cholesterol. Researchers have found that olive leaf lowers blood pressure and increases blood flow by relaxing the arteries.

Great Product

Posted by Reviewer2205214 on Feb 20, 2010

Helping with ulcerative colitis and candida - keeping the bacteria and yeasts down. I feel much better when using this. I use it in rotation with oregano oil and grapefruit seed extract.

Best Olive leaf extract so far

Posted by Reviewer1761278 on Feb 14, 2012

This is the best olive leaf extract so far. I have tried NOW brand earlier but this is way better and more effective in keeping flu away. My dad even used it for his piles (internal and external application) and reported very good result.
