“The scientific evidence is insufficient to establish a cause and effect relationship between the consumption of olive leaf water extract and an increase in glucose tolerance. It said the other human study shows an increase in glucose tolerance applicant but the results have not been replicated in other studies and no evidence had been provided on the mechanism by which the olive leaf water extract could exert the claimed effect. The benefits of olive leaf extract are mainly due to its antioxidant compounds like oleuropein, apigenin-7-glucoside, luteolin-7-glucoside, and hydroxytyrosol. “It will be particularly beneficial to individuals with impaired glucose tolerance, a common condition in the general adult population, particularly among those who are overweight or obese,” it told EFSA.Ĭomvita identified two human studies and three animal studies as being pertinent to the claim but in an opinion published earlier this month, the NDA panel said no conclusion could be drawn from one of the human studies and the three animal studies as they involved foods not complying with Comvita’s specifications.

The natural health products company had proposed the claim that, “daily intake of supplemental olive leaf extract polyphenols contributes to the reduction of the blood glucose rise after meals.” It proposed a daily intake of five of its OLE (olive leaf extract) capsules, each containing 400 mg The panel on Dietetic Products, Nutrition and Allergies (NDA) was asked its opinion after an application from Comvita New Zealand Limited in September. 7 However, scientific evidence for health effects of using olive leaf extract has been deemed insufficient by the European Food Safety Authority to prove any cause-and-effect relationship. There is not enough evidence to back a claim that olive leaf water extract boosts glucose tolerance, a European Food Safety Authority (EFSA) health claims panel has found. Studies suggest that olive leaf extract could help balance blood sugar in type 2 diabetes patients.
