What Is Magnesium Citrate?

Magnesium is one of the most critical minerals for high-performance physiology. When bound to citric acid, it forms Magnesium Citrate — a form known for enhanced solubility and absorption.

This form delivers rapid and effective support for neuromuscular function, cardiovascular health, bone density, and cellular energy. It also gently supports digestive regularity, making it a multifunctional supplement with powerful, daily applications.

Whether you're training hard, managing stress, or optimizing sleep — Magnesium Citrate is a foundational tool to keep your body balanced, resilient, and fully charged.

Marco’s Grounds™ Magnesium Citrate Sourcing

At Marco’s Grounds™, we source our Magnesium Citrate from a family-owned citrus farm in Yunnan, China — a region celebrated for its rich soil and high-quality fruit.

We extract citric acid from these nutrient-dense citrus peels and bond it with purified magnesium oxide through a precision-controlled process. The result: a potent, clean, and highly absorbable Magnesium Citrate that delivers consistent performance benefits in every dose.

Dosing Principles and Rationale

Clinical research supports daily intake of 200–400 mg of elemental magnesium, depending on age, lifestyle, and stress levels.

At Marco’s Grounds™, we follow hormetic dosing principles — delivering just enough to activate biological benefits without unnecessary overload. For optimal results, Magnesium Citrate should be taken with food, preferably in the evening to support relaxation and improve sleep quality.

Magnesium Citrate Key Mechanisms

1. Muscle and Nerve Function

Regulates calcium and potassium transport across cell membranes
Reduces cramps and spasms
Promotes full-body relaxation and neuromuscular recovery [1]

2. Energy Metabolism

Serves as a cofactor in ATP synthesis, powering cellular energy and metabolic efficiency [2]

3. Cardiovascular Health

Supports vascular relaxation and electrolyte balance
Helps maintain healthy blood pressure and heart rhythm [3]

4. Digestive Support

Acts as a gentle osmotic laxative, drawing water into the intestines to ease bowel movements and promote regularity [4]

5. Sleep and Stress Regulation

Enhances GABA activity in the brain, calming the nervous system
Reduces cortisol and physical tension, aiding deeper sleep and resilience under stress [5]
