Olive leaf extract is currently available in the form of 500 mg. tablets. The routine dosage is one tablet every six hours or four throughout the day. Take the supplement between meals for best results. In the case of bad colds or flu, you can use two tablets every six hours. For acute infections, some individuals have taken more -- three and even four every six hours -- and reported rapid relief. If you encounter a "die-off" effect, cut back on the number of tablets you are taking or temporarily discontinue them. See the section on "die-off effect." For healthy folks seeking more energy or the prevention benefits of olive leaf extract, we suggest one or two tablets a day. The younger and cleaner the body, the more responsive it is to supplements such as this. When a person becomes older and more toxic, more of the supplement is required to do the job.
