H2 Relief Bath Tablets Review, Test Results & 10% Discount

This H2 Relief Bath Tablets review covers the magnesium-based hydrogen bath tablets now marketed by Drink HRW as RELIEF Hydrogen Bath Tablets. The tablets react with warm water to generate molecular hydrogen without requiring an electronic bath machine. This page includes independent H2 Relief Bath Tablets test results, hydrogen-output measurements, footbath and full-bath concentrations, current directions, product ingredients, pricing, and information about the available H2 Relief Bath Tablets discount.

Independent H2HUBB testing measured approximately 0.83 mg/L of dissolved molecular hydrogen in a 3-liter footbath using one tablet. A separate full-bath evaluation using 38 tablets in 113.5 liters, or 30 gallons, measured approximately 1.34 mg/L. The independently verified full-bath result applies specifically to that tested tablet-to-water ratio.

H2 Relief Bath Tablets Review & Test Results

Drink HRW RELIEF Hydrogen Bath Tablets are premeasured magnesium-based tablets designed to generate molecular hydrogen when placed in warm water. The current 60-count formulation lists 240 mg of elemental magnesium per tablet together with malic acid, dextrose, tartaric acid, adipic acid, and sodium stearyl fumarate.

H2HUBB evaluated both total hydrogen-gas generation and the amount of hydrogen retained in tested water volumes. During gas-evolution testing, one tablet produced approximately 168 mL of hydrogen gas in hot water. Under an acid-assisted condition using vinegar, one tablet produced approximately 235 mL of hydrogen gas.

The higher acid-assisted result documents the tablet’s approximate gas-generation capacity under a reaction condition designed to accelerate the magnesium reaction. It should not be presented as the amount that will necessarily remain dissolved in ordinary bathwater.

For the footbath evaluation, H2HUBB placed one tablet into 3 liters of distilled water at approximately 103.4°F. The measured dissolved-hydrogen concentration reached approximately 0.83 mg/L, with the report listing approximately 2.4 mg of dissolved H₂ in the tested water volume.

The concentration-versus-time graph shows that the 3-liter preparation rose rapidly to approximately 0.8 mg/L, remained near that level through the early portion of the test, and then gradually declined to approximately 0.5 mg/L by 30 minutes. This illustrates why the timing of tablet dissolution and soaking can affect the concentration available in the water.

For the full-bath evaluation, H2HUBB used 38 tablets in approximately 113.5 liters, or 30 gallons, of tap water. The measured concentration was approximately 1.34 mg/L. The report lists approximately 147.55 mg of dissolved H₂ in the tested bath.

The full-bath result must remain connected to the tested protocol. It should not be used to describe a bath prepared with 10–15 tablets, one tablet per five gallons, or another lower tablet-to-water ratio. Fewer tablets in the same water volume should be expected to produce a lower hydrogen concentration unless separate testing demonstrates otherwise.

Based on the documented hydrogen-gas production, dissolved-hydrogen concentration, portability, and practical preparation method, the evaluated H2 Relief Bath Tablets received the H2HUBB Seal of Approval.

Approximate Hydrogen Output and Dose

Based on the independently evaluated tablets and water volumes:

• Hot-Water Gas Evolution: Approximately 168 mL H₂ from one tablet
• Acid-Assisted Gas Evolution: Approximately 235 mL H₂ from one tablet
• 3-Liter Footbath: One tablet
• Footbath Concentration: Approximately 0.83 mg/L
• Report-Listed Footbath Dose: Approximately 2.4 mg H₂
• Footbath Concentration During 30-Minute Test: Approximately 0.8 to 0.5 mg/L
• 30-Gallon Full Bath: 38 tablets
• Full-Bath Concentration: Approximately 1.34 mg/L
• Report-Listed Full-Bath Hydrogen Amount: Approximately 147.55 mg H₂

The report’s dose figures are approximate and appear to rely on underlying measurements with greater precision than the rounded public concentration values. They should not be presented as exact pharmaceutical-style doses.

Independent Test Procedure

For gas-evolution testing, H2HUBB evaluated one tablet in 500 mL of distilled water at approximately 101.3°F. A separate acid-assisted evaluation used 500 mL of vinegar. Gas collection continued until water displacement stopped, and the results were adjusted to sea-level conditions.

For dissolved-hydrogen testing, H2HUBB evaluated one tablet in 3 liters of distilled water and 38 tablets in 113.5 liters of tap water. The bath-water temperature was approximately 103.4°F. The tablets were allowed to react before the dissolved-hydrogen measurements were recorded.

The 3-liter concentration was followed at five-, ten-, fifteen-, twenty-, twenty-five-, and thirty-minute intervals. Actual results may vary with water volume, water temperature, tablet count, water chemistry, reaction time, movement of the water, tub dimensions, and the amount of time between tablet dissolution and soaking.

Current Use Instructions

The current manufacturer lists two preparation ratios:

• Higher-Tablet Preparation: Add one tablet per gallon of warm water and soak for approximately 15–30 minutes.
• Lower-Tablet Preparation: Add one tablet per five gallons of warm water and soak for approximately 15–30 minutes.

These current directions differ from H2HUBB’s full-bath test, which used 38 tablets in 30 gallons. Do not describe either manufacturer preparation as producing the independently measured 1.34 mg/L unless that exact ratio is separately tested.

Allow the tablets to react in the prepared water and follow the current manufacturer label for tablet count, water temperature, soaking time, storage, and routine use.
