If a high proportion of the solute dissociates to form free ions, the electrolyte is strong; if most of the solute does not dissociate, the electrolyte is weak. “Electrolyte” is the umbrella term for particles that carry a positive or negative electric charge. In nutrition, the term refers to essential minerals in your blood, sweat, and urine.

Understanding the Context

Electrolytes are electrically charged compounds that are essential to the cells in your body. Electrolyte levels are often used to help diagnose medical conditions. Key electrolytes include sodium, potassium, chloride, calcium, magnesium, phosphorus, and bicarbonate. They're found in many foods and drinks; most people get enough through diet.

Key Insights

An imbalance can cause serious health issues and should be corrected immediately. Electrolyte drinks can help, but aren't usually necessary for everyday use. Electrolyte products, often sold as powders or sports drinks, are designed to help the body replenish its electrolytes. These drinks and powders generally contain carbohydrates and a small amount of electrolyte such as sodium, Wohlford says. A variety of hormones help the kidneys regulate electrolyte concentrations in the body.

Final Thoughts

Serum in the bloodstream is what is left after the red blood cells, white blood cells, and clotting factors are removed. Much of serum is water and it contains the bloodstream’s electrolytes. Electrolytes are minerals found in blood and sweat with a negative or positive charge. Consuming electrolyte foods and drinks supports your brain and muscle function. Electrolyte, substance that conducts electric current as a result of dissociation into positively and negatively charged particles called ions.
