Sodium magnesium supplements are a type of dietary supplement that contain both sodium and magnesium. These minerals are important for many bodily functions, including nerve and muscle function, maintaining healthy blood pressure, and regulating the body's fluid balance. While it is important to get these minerals through a balanced diet, some people may not consume enough through food alone. These supplements can help fill that gap and provide the body with the necessary nutrients. It is important to consult with a healthcare professional before taking any supplements to determine if they are right for you.
