###Human: Is there any possibility to get protein toxicity from protein shake? ###Assistant: Hi. After going through your question I feel that you are really worried about the ill effects of protein shake. Let me assure you that a protein shake is perfectly safe even if you have taken in large quantities as mentioned. The fact that even after three weeks it has not altered your renal function or liver function itself is the proof that you need not worry about the toxic effect of the protein shake. Drink plenty of fluids and try to cut down fried food and junk food as your body mass index - BMI is high. Just bring down your weight. It will ease your problem a lot. Do not worry. You will be all right.
