A study published in the August 29, 2015 issue of Phytotherapy Research demonstrated that olive leaf extract can significantly reduce LDL cholesterol and total cholesterol levels. 1
The high oleuropein content of olive leaf extract attributed to the observed benefits.
The researchers stated that:
“Olive foods such as olive oil and olive leaf are major components of [the Mediterranean] diet, and oleuropein is responsible for most of their beneficial effects. Olive leaf also contains significant amounts of oleuropein which is traditionally removed from olives because of its biting taste.
“Our findings demonstrated a potential and beneficial effect of olive leaf extract in reducing the atherogenic index. In this study, atherogenic index, defined as the ratio of non-HDL to HDL was significantly decreased in high cholesterol diet fed rats treated with olive leaf extract.”
The researchers from Celal Bayar University, Manisa, Turkey , concluded:
“The results of this study indicated that olive leaf extract supplementation decreased serum total cholesterol and LDL-cholesterol in high cholesterol diet fed rats while HDL-cholesterol and triglyceride levels remained unchanged. As alternative to statins and other drugs, olive leaf extract supplementation may help in improving the lipid profile in hypercholesterolemia.”
