Many people do not get enough servings of fruits and vegetables per day.  Following a plant-based diet is key for preventing cancer and while going through treatment.  For some people, consuming adequate amounts of fruits and vegetables can be difficult. Adding in a green powder between meals can help increase your consumption of essential vitamins, minerals, and antioxidants, all of which help your body fight cancer.  Please note some radiation oncologists discourage the use of green-powders during radiation because of its antioxidant effects. If you are currently undergoing radiation or about to start radiation, make sure to discuss this with your radiation oncologist before purchasing this product.
