Potassium Vitamin C Supplements are a dietary supplement that combines two essential nutrients, potassium and vitamin C, in one convenient tablet. Potassium is a mineral that helps regulate blood pressure, muscle function and fluid balance in the body, while vitamin C is a powerful antioxidant that supports the immune system and helps the body absorb iron. These supplements are an excellent way to ensure that your body is receiving the recommended daily intake of both potassium and vitamin C, especially if your diet is lacking in these nutrients.
