Mineral

Magnesium Gluconate

Also known as: magnesium gluconate, Mg gluconate, magnesium bis(D-gluconate)

A
Evidence

Magnesium gluconate is an organic salt form of magnesium with good bioavailability and mild gastrointestinal tolerability. Magnesium is an essential mineral involved in over 300 enzymatic reactions, including energy production, muscle function, and nervous system regulation.

Primary uses

  • Magnesium supplementation
  • Muscle relaxation and cramping
  • Sleep quality support
  • Stress and anxiety management
  • Cardiovascular health
  • Bone health

How it works

  • Cofactor in ATP synthesis and energy metabolism
  • Regulation of muscle contraction and relaxation
  • Modulation of NMDA receptors and neurotransmitter function
  • Support of normal blood pressure regulation
  • Involvement in bone mineralization and remodeling

Dosage

Typical range
200-400 mg daily (elemental magnesium)
Timing
Can be taken anytime; evening dosing may support sleep
With food
Can be taken with or without food; taking with food may reduce minor GI upset
Duration
Safe for long-term daily use; consistent intake supports maintenance of magnesium status
Special populations
RDA: 310-320 mg for adult women, 400-420 mg for adult men; higher needs in athletes and during stress

Forms

  • Powder· 70/100
  • Capsule· 70/100
  • Tablet· 70/100

Safety

Common side effects

  • Mild gastrointestinal effects (loose stools) at high doses
  • Nausea or stomach discomfort (less common with gluconate form)

Contraindications

  • Severe renal impairment or kidney disease
  • Myasthenia gravis
  • Heart block or severe cardiac arrhythmias
  • Hypersensitivity to magnesium salts

Evidence notes

Magnesium is one of the most well-researched minerals with extensive RCT evidence supporting its role in muscle function, sleep, cardiovascular health, and metabolic processes. Gluconate is a highly bioavailable, chelated form with good absorption and minimal laxative effect compared to other forms.

Grade A: Multiple well-designed human trials support the main claims.
