Dual Benefit

Mg²⁺ + Glycine
The relaxation mineral in its most elegant form. Magnesium is required for over 600 enzymatic reactions, yet an estimated 50-60% of adults are deficient. This silent deficiency manifests as muscle tension, poor sleep, anxiety, and impaired cognitive function. SereniMag delivers magnesium as a chelated glycinate complex — magnesium bound to two glycine molecules — providing superior bioavailability, excellent GI tolerance, and dual calming effects from both the magnesium ion and its glycine carrier. The magnesium acts as nature’s NMDA receptor modulator, providing voltage-dependent calcium channel blockade that calms neural excitability without sedation. The glycine contributes its own inhibitory neurotransmission and thermoregulatory sleep benefits. This is precision mineral delivery for relaxation, sleep, and foundational health.
Magnesium glycinate delivers two active components with complementary mechanisms:

The NMDA Voltage-Dependent Block

Magnesium’s most important CNS mechanism is its unique voltage-dependent NMDA receptor blockade:Why This Matters:

Magnesium in Enzymatic Reactions

Magnesium is required for:
  • ATP function: Mg-ATP is the actual substrate for kinases (not ATP alone)
  • DNA/RNA synthesis: Polymerases require Mg²⁺
  • Protein synthesis: Ribosomal function is Mg-dependent
  • Neuromuscular: Action potential propagation, muscle contraction
  • 600+ enzymatic reactions total

Population Magnesium Status

Magnesium deficiency is widespread but underdiagnosed:
PopulationEstimated DeficiencyNotes
US Adults50-60%Below RDA intake
Elderly (65+)70-80%Higher needs, lower intake
Athletes60-70%Increased losses via sweat
Type 2 Diabetics75-85%Urinary losses, insulin resistance
Alcoholics80-90%Malabsorption, urinary loss
Chronic StressElevated riskStress depletes Mg

Serum Mg: A Poor Marker

Compartment% of Body MgMeasured?
Bone60%No
Muscle/Soft Tissue39%No
Serum<1%Yes (standard test)
RBC~0.5%Yes (better marker)
Testing Limitation: Standard serum magnesium only measures <1% of total body magnesium. You can be significantly deficient with “normal” serum levels. RBC magnesium is a better (though imperfect) marker. Many clinicians now recommend empirical supplementation given the safety profile and prevalence of deficiency.

Dietary Magnesium Sources

FoodMg per Serving% DV (400mg)
Pumpkin seeds (1 oz)156 mg39%
Spinach (1 cup cooked)157 mg39%
Dark chocolate (1 oz)64 mg16%
Almonds (1 oz)80 mg20%
Avocado (1 medium)58 mg15%
Black beans (1 cup)120 mg30%
The Problem: Even with “good” sources, getting 400mg/day from diet alone is challenging, especially with modern processed diets.

Plasma Magnesium Timeline

Time to Repletion

Deficiency SeverityTime to NormalizeNotes
Mild2-4 weeksDaily supplementation
Moderate4-8 weeksConsistent dosing needed
Severe8-12+ weeksMay need higher doses initially
Patience Required: Unlike many supplements with immediate effects, magnesium repletion takes weeks. The body stores magnesium in bone and muscle, slowly equilibrating. Continue supplementation for at least 4-8 weeks before assessing full benefit. Acute relaxation effects (from glycine component and immediate Mg availability) occur faster.

Administration Notes

  • With or without food: Either acceptable; food may enhance tolerance
  • Split vs single dose: Split improves absorption and tolerance
  • Consistency: Daily use optimal for repletion and maintenance
  • Duration: Continue long-term; deficiency recurs without ongoing intake
  • Upper limit (UL): 350 mg from supplements (set conservatively for GI; glycinate rarely causes issues)

Magnesium and Stress

The Stress-Magnesium Vicious Cycle:
  1. Stress increases urinary magnesium excretion
  2. Lower magnesium increases neural excitability
  3. Increased excitability amplifies stress response
  4. Amplified stress causes more magnesium loss
  5. Supplementation breaks this cycle

Tier 1: Foundation

Efficacy

High (Deficiency-Dependent)

Validation

Very High — Essential nutrient; extensive research

Safety

Excellent — Essential mineral; well-tolerated
Tier Rationale: Tier 1 (Foundation) classification. Magnesium is an essential mineral required for 600+ enzymatic reactions. Given that 50-60% of adults are deficient, supplementation has a high likelihood of benefit. Clinical evidence supports effects on sleep, anxiety, depression, cardiovascular health, and metabolic function. The glycinate form offers superior bioavailability and GI tolerance with the bonus of glycine’s own calming effects. This is a true foundational supplement that addresses a widespread deficiency while providing specific benefits for sleep and relaxation.

Common Questions

Q: Can I take too much? A: With glycinate form and normal kidney function, difficult to overdo at reasonable doses (≤600 mg elemental). Loose stools are the first sign of excess.Q: Why glycinate instead of cheaper oxide? A: Oxide is ~4% absorbed vs glycinate ~80%. You’d need ~20× more oxide to match glycinate — and would get diarrhea.Q: Will it make me drowsy during the day? A: No. Magnesium promotes relaxation, not sedation. Morning doses support calm focus, not drowsiness.Q: How do I know if I’m deficient? A: Given 50-60% prevalence and poor testing, empirical trial is reasonable. Look for: muscle cramps, poor sleep, anxiety, stress sensitivity.

SereniMag Summary: Magnesium glycinate (200mg elemental in Luna, 150mg in Boost) delivers the essential relaxation mineral in its most bioavailable, GI-friendly form. The chelated glycine carrier provides dual benefits — magnesium for NMDA receptor modulation, muscle relaxation, and 600+ enzymatic reactions, plus glycine for additional inhibitory neurotransmission and sleep support. With 50-60% of adults deficient, this addresses a widespread gap while specifically supporting sleep quality, stress resilience, and overall calm.
