Benefits of Potassium
Supports Heart Health: Adequate potassium intake can help lower blood pressure by balancing out the negative effects of sodium. This balance is essential for cardiovascular health.
Muscle Function: Potassium plays a critical role in muscle contraction. It helps transmit electrical signals that facilitate muscle movement, making it important for athletes and those engaging in physical activities.
Nerve Function: This mineral is vital for proper nerve function, aiding in the transmission of signals throughout the nervous system. A deficiency can lead to weakness, fatigue, and other neurological issues.
Fluid Balance: Potassium helps regulate the body's fluid balance by promoting the excretion of excess sodium, which can help prevent bloating and high blood pressure.
