Sodium (Na+)

Sodium (Na+) is a vital mineral and electrolyte that helps maintain fluid balance in the body, supports proper nerve function, and aids muscle contractions. It exists mainly as a positively charged ion (Na+) and works alongside other electrolytes to regulate blood pressure and volume. Sodium is naturally found in foods like salt, processed foods, and dairy. The body carefully controls sodium levels, as too much can increase blood pressure and risk of heart disease, while too little can cause health issues like dehydration. Maintaining appropriate sodium intake is essential for overall health and bodily functions.
