Research
Although OLE has been marketed for its purported health benefits, there is no clinical evidence that it has any effect. Scientific evidence for the supposed health effect of using olive leaf extract to manage blood glucose levels has been deemed insufficient by the European Food Safety Authority to have any causal relationship. A 2024 systematic review and meta-analysis of randomized clinical trials concluded that further human studies were required to determine the possible effects of OLE on cardiovascular and metabolic measurements.
