Magnesium Orotate
Also known as: Mg orotate, magnesium orotate salt, orotic acid magnesium
Magnesium orotate is a chelated form of magnesium bound to orotic acid, proposed to enhance absorption and support cardiovascular and cellular energy metabolism. Evidence for this specific form is limited compared to well-studied magnesium salts, though magnesium itself is essential for numerous physiological functions.
Primary uses
- Cardiovascular support
- Energy production
- Magnesium supplementation
- Muscle function
How it works
- Magnesium cofactor in ATP synthesis and cellular energy metabolism
- Support for cardiac muscle contractility and electrical function
- Potential enhanced bioavailability via orotic acid chelation
- Cofactor for over 300 enzymatic reactions
Dosage
- Typical range
- 200-400 mg elemental magnesium daily (adjust based on specific product labeling)
- Timing
- Can be taken any time of day; evening dosing may support relaxation
- With food
- May be taken with or without food; taking with food may reduce gastrointestinal upset
- Duration
- Safe for long-term use; benefits for cardiovascular support may require 4-12 weeks of consistent use
- Special populations
- Adequate intake for adult females: 310-320 mg/day; adult males: 400-420 mg/day. Those with renal impairment should avoid supplemental magnesium without medical supervision.
Forms
- Powder· 70/100
- Capsule· 70/100
- Tablet· 70/100
Safety
Common side effects
- Gastrointestinal upset (nausea, diarrhea, abdominal cramping) at higher doses
- Laxative effect with excess intake
Contraindications
- Severe renal impairment or kidney disease
- Myasthenia gravis
- Heart block or serious cardiac conduction disorders (consult healthcare provider)
Evidence notes
While magnesium itself is well-established (Grade A), magnesium orotate specifically has limited human clinical trials. Some European clinical data exists for cardiac applications, but evidence is preliminary and not widely replicated in rigorous RCTs. The orotate form lacks strong differentiation evidence over other bioavailable magnesium salts.
Grade C: Mostly observational or small trials; mechanism is plausible but unproven at scale.
