Sodium chloride, commonly known as table salt, contains the mineral sodium. This essential mineral is crucial for various bodily functions, including maintaining fluid balance, supporting nerve function, and aiding muscle contractions. While salt is predominantly known for its flavoring and preservative qualities, its mineral content plays a vital role in health. However, excessive intake of sodium can lead to high blood pressure and other cardiovascular issues, so moderation is important in dietary consumption. Salt is widely available and can be naturally sourced from seawater or mined from underground deposits.
