Noni juice is a natural fruit juice and it is impossible to overdose on noni! A recommended starting dose is 1oz. once or twice a day (morning and evening). It is best to drink noni juice on an empty stomach first thing in the morning or half an hour before meals. Once your body becomes accustomed to noni you can increase your dosage as desired.
It is perfectly fine to rinse down or mix your noni juice with other fruit juices or water.
