What actually helps with muscle cramps

Sudden, involuntary, and painful contractions of muscles, commonly affecting the legs, feet, or back, often occurring at night or during exercise.

Magnesium
mineralevening
Strong

Magnesium is essential for muscle relaxation, acting as a natural calcium channel blocker. It regulates the neuromuscular junction by modulating acetylcholine release and supporting the calcium-magnesium ATPase pump that returns muscles to resting state.

Dose: 300–400 mg

Taurine
amino_acid
Strong

Taurine acts as an osmolyte maintaining cell volume and electrolyte balance in skeletal muscle. It also modulates calcium handling in the sarcoplasmic reticulum, reducing excessive calcium-induced contractions that cause cramps.

Dose: 1000–3000 mg

L-Citrulline
amino_acid
Strong

Improved blood flow enhances oxygen and nutrient delivery to muscles. Accelerates lactate clearance.

Dose: 6–8 g

Potassium
mineral
Moderate

Potassium is critical for maintaining the resting membrane potential of muscle cells. Hypokalemia causes depolarization of the cell membrane, increasing excitability and spontaneous contractions leading to cramping.

Dose: 99–200 mg

Calcium
mineralsplit
Moderate

Calcium is essential for the excitation-contraction coupling in muscle fibers. It triggers the actin-myosin cross-bridge cycle, and both deficiency and imbalance with magnesium can cause spontaneous, sustained muscle contractions (cramps).

Dose: 500–1000 mg

Phosphorus
mineral
Moderate

Maintains cellular membrane potential and electrolyte balance. Supports calcium-phosphate homeostasis for neuromuscular function.

Dose: 500–800 mg
