This product is a shake intended for people on dialysis treatment as I am. The dialysis treatment is a process in which your blood is cleaned of toxins due to kidney failure-the kidneys are the filters of the body and if they become impaired one suffers since the toxins stay in the body with deadly consequences. This treatment helps you stay alive for years even though your kidneys are not working. But, like any medical treatment, it has horrible side effects and one of them is that you get out of the treatment depleted of vitamins, minerals, and proteins-you feel tired, washed out, cranky, hungry, thirsty, wobbly, dizzy, and without energy-in fact one feels like a zombie. One good thing is that you can drink this shake and it replenishes your body again and you start feeling like yourself again. I drink it every time I get out of dialysis and it works for me-I have been in dialysis for seven years and many people don't believe I am since I look good and energetic. I recommend it to anyone in dialysis and maybe in other treatments but it is important to consult with your doctor first- it is not good to auto medicate oneself.
