The main function of the kidneys is the excretion of toxic substances and blood filtration, but they also perform other important functions, such as maintaining the balance of electrolytes in the body, regulating blood pH, producing hormones, etc. These organs are in constant activity, so it is essential to take certain precautions to avoid overloading them. The compounds that help in kidney health are diuretics, antioxidants and those that help to prevent the accumulation of potassium in the blood.
