In general, electrolytes come from a negative or a positive charge. In terms of nutrition, essential minerals are present in our blood, sweat, and urine. There are a variety of electrolytes that are found in our body, such as sodium, chloride, calcium, bicarbonate, phosphate, magnesium, and potassium. These are crucial for maintaining nerve balance, muscle function, protecting us from dehydration, and maintaining the level of acid and base in our body. The source for electrolytes is table salt, fruits, vegetables, seeds, nuts, dairy products, etc. Hydration is vital to keep yourself healthy and maintain the electrolytes in your body.
