Magnesium Glycinate
The Formula

What's Inside and Why

Supplesmart stands for full clinical disclosure. We provide the exact raw ingredient form, precise elemental dosage, and the direct scientific rationale behind our sourcing.

Ingredient Amount Per Serving Form Role in Formula Dosage Rationale Status
Magnesium 200 mg (elemental) Magnesium Bisglycinate Chelate Supports muscle relaxation, neural calm, and optimal sleep cycle.

Matched to clinical trials demonstrating high absorption and stomach comfort at 200 mg elemental dose.

Standard

Why This Form?

Magnesium Glycinate (bisglycinate) is magnesium bound to the amino acid glycine. This organic compound structure resists degradation in stomach acid, leading to vastly superior biological absorption and zero gastrointestinal distress compared to inorganic alternatives like Magnesium Oxide.

Why This Amount?

A dose of 200 mg of elemental magnesium represents roughly 50% of the recommended daily intake. This provides an effective therapeutic dose to correct subclinical deficiencies while seamlessly integrating with dietary intake without risking absolute mineral saturation.

Full Disclosure

We strictly reject proprietary blends or hidden active quantities. Every single active molecule and excipient used is quantified and verified by third party testing. You receive pure, clean, completely traceable nutritional chemistry.

What the Science Says

Not Every Claim Has the Same Evidence.

We map active ingredients directly to specific physical claims, classifying the maturity of supporting scientific consensus into transparent tiers.

Strongly Supported Robust clinical validation & consensus
Supports Muscle Recovery

Clinical data confirms Magnesiums key role in regulating calcium binding, promoting muscle fiber relaxation, and mitigating intense nocturnal cramping.

Standard
Improves Sleep Quality

Multiple double blind, randomized controlled trials show that magnesium bisglycinate increases sleep efficiency and supports the natural melatonin cycle in adults.

Standard
Limited / Mixed Emerging research or inconsistent human data
Reduces Acute Anxiety

While glycine has neurotransmitter calming properties, large scale clinical trials investigating magnesium glycinate specifically for generalized anxiety disorder remain early and ongoing.

Research
Marketing / Anecdotal Claims unsupported by sufficient scientific literature
Rapid Cognitive Boosting

Popular biohacking circles market magnesium for immediate mental clarity. However, magnesium glycinate does not easily cross the blood brain barrier; only specialized forms like Magnesium L-Threonate show emerging cognitive promise.

Limited

What We Know

  • We strictly reject proprietary blends or hidden active quantities. Every single active molecule and excipient used is quantified and verified by third party testing. You receive pure, clean, completely traceable nutritional chemistry.
  • Gentle Gastric Tolerance: Does not act as a strong osmotic laxative, preventing the common discomfort of Magnesium Oxide.
  • Regulates Sleep Cycles: Acts as a natural GABA agonist to help down-regulate the nervous system for deeper sleep.
  • Relaxes Muscle Fibers: Blocks calcium channels locally to prevent persistent hyperexcitability and cramping.

What We're Still Learning

  • Synergy with Melatonin: While co-supplementation is popular, the precise molecular synergetic benefits remain partially quantified.
  • Impact on Chronic Stress: Early cortisol correlation models show promise, but definitive systemic human evidence requires broader cohorts.
  • Optimal Time of Day: Circadian peak absorption variance is widely theorized, though robust longitudinal timing data is limited.
  • Long-term Retention Variance: The retention rate difference between chelated magnesium forms in tissue remains heavily debated in metabolic science.
