Elemental Magnesium

The Reactive Metal Behind Hydrogen-Rich Water: Up to 12 PPM H₂ Per Tablet

Elemental magnesium is the pure reactive metal form of magnesium. Unlike magnesium citrate, glycinate, or oxide, which dissolve passively, elemental magnesium reacts with water: Mg + 2H₂O → Mg(OH)₂ + H₂. This reaction generates up to 12 PPM of dissolved molecular hydrogen, a selective antioxidant that targets the most harmful free radicals while leaving beneficial reactive oxygen species untouched.

Each H2 Molecular Tablet provides 80 mg elemental magnesium (19% DV) plus hydrogen-rich water at up to 12 PPM dissolved H₂. Research on magnesium supports sleep quality and blood sugar regulation; meta-analyses on H₂-rich water show improvements in endothelial function and oxidative stress markers.

Elemental Magnesium
What It Is

What Is Elemental Magnesium?

Elemental magnesium is the pure reactive metal form of magnesium, the actual Mg (atomic number 12) that participates in chemical reactions. It's an alkaline earth metal that acts as a cofactor for 300+ enzymatic reactions in the body, involved in energy production, protein synthesis, muscle and nerve function, and DNA replication.

In Wellness Extract's H2 Molecular Tablets, elemental magnesium serves a dual role: it provides 80 mg of elemental magnesium per tablet (19% DV), and it reacts with water to produce molecular hydrogen gas (H₂). This reaction, Mg + 2H₂O → Mg(OH)₂ + H₂, generates up to 12 PPM dissolved hydrogen, far above the 1–2 PPM threshold in most H₂ water research.

Dual Function

Delivers Both Magnesium and Molecular H₂

Unlike magnesium citrate or glycinate, which dissolve passively and deliver magnesium only, elemental magnesium actively reacts with water to generate dissolved molecular hydrogen. This makes it the reactive ingredient that transforms an ordinary mineral supplement into a hydrogen-rich water delivery system.

Selective Antioxidant

H₂: Targets the Most Harmful Free Radicals Selectively

Molecular hydrogen is classified as a selective antioxidant; it targets hydroxyl radicals and peroxynitrite (the most cytotoxic reactive oxygen species) while leaving other ROS that serve normal physiological functions untouched. This selectivity distinguishes it from broad-spectrum antioxidants like Vitamin C.

Stabilizers

Malic & L-Tartaric Acid Keep H₂ in Solution

H2 Molecular Tablets include malic acid and L-tartaric acid, which acidify the water environment around the tablet and stabilize the dissolved hydrogen in solution, keeping more dissolved H₂ in the drink long enough for consumption before it off-gasses.

How It Works

The Chemistry Behind Hydrogen-Rich Water

H2 Molecular Tablets work through a well-understood chemical reaction. Understanding the mechanism clarifies exactly what each tablet delivers.

H₂ Generation

Mg + 2H₂O → Mg(OH)₂ + H₂: The Core Reaction

How it works

When dropped in water, elemental magnesium reacts immediately. Malic and L-tartaric acid stabilize the dissolved hydrogen gas in solution. The result is up to 12 PPM dissolved H₂, well above the 1–2 PPM threshold studied in most H₂ water research.

Chemistry
Membrane Permeability

H₂ Reaches Inside Mitochondria and Crosses Blood-Brain Barrier

Why it matters

Molecular hydrogen is one of the smallest possible molecules. It crosses biological barriers rapidly and reaches the inside of cells, the mitochondrial membrane, and even the brain, areas most antioxidants cannot access efficiently.

Dosage & Forms

H2 Molecular Tablets: How to Use

Drop one tablet into 12–16 oz of water. Let fully dissolve (1–3 min). Drink immediately; dissolved hydrogen off-gasses if left standing.

Form Comparison

Elemental vs. Salt Magnesium Forms

FormDetails
Elemental Mg (tablets)Generates up to 12 PPM H₂; also delivers 80 mg Mg per tablet
Mg CitrateNo H₂; high magnesium bioavailability; best for Mg alone
Mg GlycinateNo H₂; gentle, well-tolerated; best for Mg alone
Mg OxideNo H₂; low bioavailability; generally not recommended

Key difference: only elemental magnesium reacts with water to generate H₂. If your goal is purely magnesium supplementation, citrate or glycinate are better-studied for bioavailability. If your goal is hydrogen-rich water with co-delivered magnesium, H2 Molecular Tablets are the form designed for that.

Usage Guide

When and How to Use H2 Tablets

Each tablet: 80 mg elemental Mg (19% DV) + up to 12 PPM dissolved H₂.

GoalWhen to Use
Sleep support30–60 min before bed; magnesium's GABA modulation benefits from proximity to sleep onset
Exercise recoveryShortly before or after training; H₂ may reduce exercise oxidative stress
Daily antioxidant1 tablet per day with any beverage

RDA for magnesium is 320–420 mg/day for adults. Each tablet contributes ~80 mg; the rest should come from diet (nuts, seeds, leafy greens). Total supplemental magnesium should not routinely exceed 350 mg/day without medical guidance.

Why Elemental Magnesium?

Elemental vs. Salt Forms: Why It Matters for H₂

A standard magnesium supplement dissolves passively and delivers only magnesium ions. H2 Molecular Tablets use elemental magnesium precisely because it reacts with water, making it the active ingredient that drives the H₂ generation that salt forms cannot produce.

Frequently Asked Questions

Answers About H2 Molecular Tablets

Elemental magnesium is the pure reactive metal that participates in chemical reactions. Other supplement forms (citrate, glycinate, oxide) are magnesium salts that dissolve passively and deliver only magnesium ions. Elemental magnesium's reactivity is what allows it to react with water and generate molecular hydrogen; you cannot generate H₂ with magnesium citrate.

Molecular hydrogen (H₂) is a selective antioxidant that neutralizes the most cytotoxic free radicals (especially hydroxyl radicals and peroxynitrite) while leaving beneficial ROS signaling untouched. Its tiny molecular size lets it reach inside mitochondria and across the blood-brain barrier. A 2020 meta-analysis of 6 RCTs found H₂-rich water significantly improved endothelial function and oxidative stress markers.

Each H2 Molecular Tablet generates up to 12 PPM dissolved molecular hydrogen in 12–16 oz of water, well above the 1–2 PPM threshold used in most published H₂ water research. Malic and L-tartaric acid stabilize the dissolved hydrogen so it stays in solution long enough to consume.

Drop one tablet into 12–16 oz of water at room temperature (cold water slows the reaction). Let it fully dissolve, approximately 1–3 minutes. Drink immediately after dissolution; dissolved hydrogen begins off-gassing once the tablet is consumed, so drinking promptly captures the most H₂. Do not pre-dissolve and store.

Yes, a 2012 double-blind RCT (n=46) found magnesium supplementation significantly improved sleep efficiency, total sleep time, sleep onset latency, and early morning awakening vs. placebo in elderly adults with insomnia. Mechanism: GABA receptor modulation, the primary inhibitory neurotransmitter system involved in sleep onset.
