 [ Symptoms ] what is your opinion on olive leaf extract [ Disease ] i guess i am going to assume you are asking about olive leaf extract for anti aging or immune support as these are the two new miracle uses for the product i can tell you there are no human studies that support any claims of anti aging effects or immune support from the use of olive leaf extract to me that says it all if there is no science behind it i personally would not spend my money on it diet supplements like olive leaf extract are not highly regulated in the u s they undergo some level of review for safety but they are not tested for example to see if they really do everything the makers claim they do that is why i like to rely on real scientific studies before i put my faith in a supplement that is about all i can tell you good luck
