Sodium potassium supplements are a combination of two essential minerals that are crucial for maintaining proper bodily functions. Sodium is important for maintaining fluid balance, while potassium helps to regulate muscle and nerve activity. These supplements are commonly used by athletes and individuals who engage in high-intensity exercise, as they can help to prevent cramping and improve overall performance. Additionally, they may be beneficial for those who have low sodium or potassium levels due to certain medical conditions or medications. It is important to talk to a healthcare professional before starting any new supplement regimen.

Frequently Asked Questions (FAQs)

1. How do you increase sodium and potassium levels?

People can make a key dietary change to help lower their risk: Eat more fresh vegetables and fruits, which are naturally high in potassium and low in sodium, but eat less bread, cheese, processed meat, and other processed foods that are high in sodium and low in potassium.

2. What do sodium and potassium help with?

Potassium and sodium are electrolytes that help your body maintain fluid and blood volume so it can function normally. However, consuming too little potassium and too much sodium can raise your blood pressure.

Your total intake of potassium should not be greater than the recommended amounts, unless ordered by your doctor. In some cases, too much potassium may cause muscle weakness, confusion, irregular heartbeat, or difficult breathing.
