Please drink responsibly!!!! One dose which is about 5-6oz (6oz/ounces=177ml) is enough for a whole day, but to be on the safe side please ask your DR. If you are perfectly fine drinking this combination of ingredients. If you are not used to drinking pure juices start with 2 FL Oz in the morning with a glass of water (not COLD water, preferably room temperature) and gradually over a period of two weeks lift it up to 5-6 FL Oz, just because it is extremely powerful and your body needs to adjust. I recommend this juice, especially for cancer patients, and cancer survivors. Also, just to tell you if you do try this juice your stool will be slightly red/beet color, just in case if you were wondering! This is 100% natural and you don't have to worry about when you do see different colors, but I feel the need to inform you about that too.
