Olive Leaf Extract

What it is:

Olive leaf extract is derived from the leaves of the olive tree and contains several bioactive compounds, with the most notable being oleuropein. Oleuroplein is thought to be responsible for many of the health benefits associated with olive leaf extract. 


Olive leaf extract has strong antioxidant and antiinflammatory properties, has been shown to be a strong supporter of cardiovascular health, and most notably for a fat burner, has been shown to help in regulating blood sugar levels. By helping to regulate blood sugar levels, olive leaf extract can reduce insulin spikes and crashes. Additionally, some studies suggest olive leaf extract may have an effect on appetite regulation, helping to reduce overeating and supporting weight loss efforts. 


This 2021 double-blinded, placebo-controlled, randomized controlled trial examined the effects of supplementation with olive leaf extract combined with a calorie-restricted diet. Results showed that compared to a calorie deficit and exercise alone, adding olive leaf extract enhanced these benefits by further reducing body weight, body mass index, and fat mass. This study indicates that olive leaf extract supplementation improves metabolic risk factors more effectively than a hypocaloric diet alone.
