Description
Electrolytes are essential minerals—such as magnesium, potassium, calcium, sodium, chloride, and phosphate—that carry an electric charge and are present in body fluids and tissues. These minerals play a crucial role in maintaining fluid balance, regulating pH levels, and supporting muscle contractions, including heartbeat regulation. Electrolytes are also involved in nerve signal transmission, blood clotting, tissue repair, and the delivery of nutrients to cells. When electrolyte levels are imbalanced—due to dehydration, illness, or excessive physical activity—it can result in serious health issues like muscle cramps, irregular heart rhythms, and fatigue. Maintaining proper electrolyte levels is essential for ensuring that the body’s physiological processes run smoothly, particularly in maintaining hydration, muscle function, and nervous system support.
Functions in the Body
Category
Deficiency Symptoms
A deficiency in electrolytes can cause symptoms such as irregular heartbeat, lethargy, fatigue, confusion, muscle spasms, fever, and swelling.
Synergy & Antagonism
Electrolytes work synergistically to support hydration, nerve signaling, and muscle contractions, with sodium and potassium balancing fluids and calcium and magnesium aiding muscle function. However, certain electrolytes also exhibit antagonistic effects, such as calcium and phosphorus, which compete for absorption, or sodium and potassium, which must remain balanced to prevent deficiencies or excesses.

Warnings
Excessive intake of individual electrolytes can lead to serious health issues, such as hypernatremia (excess sodium), hyperkalemia (excess potassium), hypercalcemia (excess calcium), and muscle or neurological damage from excess magnesium. It’s essential to maintain balance when supplementing.
Food Sources
Foods rich in electrolytes include spinach, kale, cheese, coconut water, celery, lettuce, avocados, almonds, and dates.
Time Frame
Electrolytes are best consumed in the morning on an empty stomach for optimal absorption, especially after periods of dehydration or physical exertion.
Depleted By
Factors that can deplete electrolytes include steroids, diuretics, laxatives, vomiting, diarrhea, eating disorders, excessive sweating, and kidney or liver problems.
