Electrolyte Complex (Sodium, Potassium, Magnesium) vs Peak ATP (Adenosine 5'-Triphosphate Disodium)

Mechanism

Electrolytes maintain critical physiological functions: Sodium (Na+) is the principal extracellular cation regulating plasma volume, blood pressure (via RAAS system), nerve impulse conduction (fast sodium channels), and glucose absorption (SGLT1 co-transporter). Potassium (K+) maintains resting membrane potential via Na+/K+-ATPase, essential for cardiac rhythmicity and muscle contraction. Magnesium (Mg2+) is required for ATP function (Mg-ATP), muscle relaxation (calcium antagonism), and >600 enzymatic reactions. Sweat contains ~40-60 mmol/L sodium, ~4-8 mmol/L potassium, and trace magnesium. Hyponatremia from excessive water intake without sodium replacement during prolonged exercise is potentially fatal.

Standard Dosing

Varies by activity level: 500-1500mg sodium, 200-400mg potassium, 100-200mg magnesium per liter of fluid during exercise

Timing

Before, during, and after exercise. Daily electrolyte support for low-carb/ketogenic diets (increased electrolyte excretion). First thing in morning for general hydration.

Cycle Duration

ongoing during training; increased during heat, prolonged exercise, or ketogenic diet

Side Effects

• GI cramping (hyperosmolar solutions)
• Bloating
• Hypernatremia/hyperkalemia if excessive
• Diarrhea (magnesium component)

Contraindications

• Hyperkalemia with potassium component
• Heart failure (sodium restriction may be required)
• Renal failure (impaired electrolyte excretion)

Mechanism

Oral ATP supplement that increases extracellular ATP levels, improving blood flow via purinergic receptor activation on endothelial cells. Enhances muscular excitability, recovery, and lean body mass. Does not significantly raise intracellular ATP (that's produced endogenously).

Contraindications

• None established
