Because protein is an essential part of human body, if it is supplemented too much, it will produce deamination and turn protein into sugar or fat for storage. In other words, if you eat too much, you will get fat. And this process will produce nitrogen-containing substances harmful to the body, which can be called toxins. The amount of urea will increase, increasing the burden on the kidneys.
The safest thing is food supplement. It is best to choose high-quality protein food such as eggs, lean meat, fish, shrimp, chicken and bean products. Excessive protein produces acidic substances in the body's metabolism, which increases the excretion of urinary calcium and leads to the loss of calcium in the body.
