Magnesium

Why It Matters

Magnesium is an electrolyte that plays a key role in a range of physiological processes, including cellular function, nerve conduction, and energy metabolism. Magnesium also supports psychological well-being by modulating the hypothalamic-pituitary-adrenal axis and neurotransmitter signaling. (source, source)

Magnesium is a required cofactor for over 300 enzymatic reactions, including ATP synthesis, protein formation, and DNA replication. It directly regulates calcium channel activity in muscle cells, making it essential for both contraction and relaxation cycles. A deficit disrupts every system that depends on cellular energy.

Low Magnesium: Energy and Recovery Breakdown

Low serum magnesium levels stem from physiological factors affecting the kidneys' ability to regulate magnesium excretion and the intestines' absorption of this vital mineral. Inadequate intake of magnesium-rich foods and nutrients like vitamin D also contributes to deficiencies. (source, source, source)

Potential Performance Impact:

• Impaired ATP synthesis, reducing available energy for training and recovery
• Increased muscle cramping and spasm frequency during exertion
• Elevated cortisol and stress response impairing sleep quality
• Compromised nerve conduction affecting coordination and reaction time

Optimization

Eat magnesium-rich foods: Dietary magnesium intake increases serum magnesium levels by providing absorbable mineral substrate in the small intestine. (source, source)

Protocol: Consume at least two servings of magnesium-rich foods per day. One serving examples: Chia Seeds (2 tablespoons), Pumpkin Seeds (1/4 cup), Almonds (1 oz), Cashews (1 oz).

Avoid alcohol: Alcohol acts as a diuretic, increasing magnesium excretion. Decreasing alcohol intake regulates magnesium concentrations in the body. (source, source)

Protocol: Limit consumption to one or two drinks daily, with the goal of less than three per week.

Perform breathwork and/or meditation: Stress is negatively associated with magnesium concentrations. When the body is under stress, it produces cortisol and utilizes magnesium at a higher-than-normal rate, depleting blood magnesium levels. Breathwork activates the parasympathetic nervous system, decreasing stress hormones and regulating magnesium stores. (source, source, source)

Protocol: Sit down and calmly focus on your breath while box breathing for up to five minutes.

Supplement with magnesium: Magnesium supplementation directly increases serum magnesium levels. (source, source)

Protocol: Supplement with at least 200 mg of magnesium daily.

High Magnesium: Kidney and Neuromuscular Risk

Elevated serum magnesium levels result from impaired kidney function, as the kidneys play a vital role in regulating magnesium levels. Excessive intake of magnesium-rich foods or supplements also leads to high serum magnesium levels. (source, source, source)

Potential Performance Impact:

• Depressed neuromuscular function causing muscle weakness and hypotonia
• Cardiovascular depression including hypotension and bradycardia
• Impaired respiratory drive at critically elevated levels
• Gastrointestinal distress reducing nutrient absorption

Optimization

Limit magnesium-rich foods: Dietary magnesium intake increases serum magnesium levels. (source, source)

Protocol: Monitor and limit excess consumption of magnesium-rich foods, like dark chocolate, avocados, and nuts.

Avoid magnesium-based products: Laxative use increases blood magnesium levels. Magnesium is a primary ingredient in laxatives and antacids, and consumption increases magnesium concentrations. (source, source)

Protocol: Monitor intake and magnesium concentration in products such as laxatives and antacids.

Avoid magnesium supplements: Supplementation with magnesium increases serum magnesium levels. (source, source)

Protocol: Monitor excess magnesium intake and magnesium supplement concentrations.
