Most of the time, alternative treatments alone can't be used to help intrinsic acute renal failure. However, there are some alternative options that, when used in conjunction with treatment from a doctor, may help. Diet control is one alternative method that may be effective. It's important to maintain a diet that is high in carbohydrates, moderate in protein, and low in potassium. Also, because your blood may be lacking certain vitamins and minerals, many people find it beneficial to take vitamin supplements. However, since intrinsic acute renal failure can be a potentially dangerous condition, it's important to consult your doctor about any supplements or other alternative treatments before trying them.
