i guess i'm going to assume you're 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's no science behind it i personally wouldn't spend my money on it. diet supplements like olive leaf extract aren't highly regulated in the u. s. they undergo some level of review for safety but they aren't tested for example to see if they really do everything the makers claim they do. that's why i like to rely on real scientific studies before i put my faith in a supplement. that's about all i can tell you. good luck!
what is your opinion on olive leaf extract?
