Hydrogen Water Concentration (PPB)-Does it Matter?

Hydrogen water is gaining ground, and claims made by companies manufacturing hydrogen water bottles about the concentrations of the dissolved hydrogen in water are our focus in this article.
As the end-user, we bring you a simple, elaborate view of the facts you need to know before choosing a device.

How Hydrogen Dissolves in Water

Your ordinary water has two portions of hydrogen to one part of the oxygen ratio. Chemically put, every two hydrogen molecules tie themselves around one molecule of oxygen, hence the formula H2O. This hydrogen however is not available to us. We need to split the water into Hydrogen and Oxygen and then add that H2 molecule back to the water. Think of a carbonated drink making process. Hydrogen water is just hydrogen gas dissolved in water.

Under normal atmospheric pressure and with a temperature of 25°C (77F), hydrogen has a maximum dissolution of 1600 PPB (1.6 PPM), the gas saturation in water balances to the same gas outside the water.

What Is “ppm?”

The acronym ppm stands for “parts-per-million”. It is a measure of how much one substance (called “solute”) dissolves in water (called “solvent”). This measurement is often useful in daily life. The concentration of many substances can be measured in ppm, including the water’s minerals and the oxygen in fish tanks. Although the ppm is often used to measure concentration, it does not provide information about the water’s volume. We need to know the total amount solute dissolved into the water. This information is crucial, for example, in determining the therapeutic dosage of medicine or the ingested toxin level. The ppm ratio alone doesn’t tell us how many solutes the water contains. It does not include the container size we are testing. Scientists use a different unit of measurement to convey this information. It specifies the solute’s concentration in units that are “mass per unit volume”. Commonly, the unit is “milligrams per liter”, abbreviated as mg/L. The mg/L refers to the solute’s mass relative to a fixed volume, one liter.

Notice: The ppb (parts-per-billion) is often used to measure the solute concentration. The ppb is not mentioned in this article. However, 1 ppm equals 1000 ppb

What is the relationship between mg/L and ppm?

One part per million is a substance (solute) that is dissolved in one million parts of a solution. In our case, the solute is H 2, hydrogen, and the solution water. What is a “part?”? A unit of measure is a “part”, in this case, the “milligram (mg). Thus, 1 mg of H 2 (or “1 part”) dissolves in 1,000,000 milligrams water (“1 million parts”) which is “one part per thousand”. A liter of water weighs 1 million grams, so 1 ppm equals 1 mg/L for dilute concentrations.

Note: This applies only to comparing mass units, but not volumes, moles or molecules.

The unit of measurement ppm represents the ratio of the amount dissolved substance to the water in which it is dissolved. A milligram of a substance will dissolve in one million milligrams water. This gives it a concentration of “1 percent per million”. One liter of water weighs one million milligrams. Therefore, 1 part per Million is the same as 1 mg per liter when referring to a volume of one-liter. The majority of flow-through devices can produce a liter or more water with the same H 2 concentration. This means that the measured concentration from this type of device will represent the amount of H 2 we would consume if we drank one liter. The measurement of H 2 water from other technologies (tablets and sticks, cartridges, etc.) must be interpreted. The ppm measurement must then be converted to mg/L using the volume of H 2 water being tested. This conversion is the only way to determine how much H 2 you will consume when we drink the entire contents.

To attain a dissolution above 1.6 PPM, hydrogen gas molecules are added to the water under pressure. This dissolution is done by a hydrogen water generator or hydrogen water bottle which is designed to withstand internal pressure.

The quantity of gas dissolved in water in PPB (parts per billion) or in PPM (parts per million) depends on its temperature and pressure directly proportional. The solubility of the gas also depends on its physical and chemical qualities like size, affinity to water, and ability to separate in an electric field.

On-demand hydrogen water generators create hydrogen-infused water using an electrolysis process.

During the process, the hydrogen atom splits from the oxygen atom in the water molecule. The electrolysis happens in a cell within the hydrogen generator. Oxygen is expelled outside the device (some of the good devices) and hydrogen bubbles trough the water.

You can now use a hydrogen water bottle in the comfort of your home. Just fill your bottle with your ordinary tap water and press a button. The hydrogen gas infuses into the water in about 5 to 10 minutes.

Concentration Claims by Hydrogen Water Manufacturing Companies.

From the onset, hydrogen water is proven to very beneficial to your health but does more hydrogen mean more benefits?

Manufacturing companies have made the many claims to promote hydrogen water and related products like portable generators and inhalers.

We don’t want you to ride on the hype for hydrogen water and miss out on its downside as the end-user. You should have a balanced and realistic view of the product. We think that these issues may be of concern to you:

1. The high cost of hydrogen measuring devices is prohibitive. Hydrogen meters are expensive for users who need a one-off measurement of hydrogen levels in their water.
This is where our hydrogen test reagent drops come as an easy and reliable solution.

2. The inability for dissolved oxygen to last long in a plastic containers makes it expensive to package. Hydrogen is a very small molecule and is known to diffuse through plastic and other materials. This quality makes your hydrogen water lose hydrogen even in sealed aluminum pouches.

The cost of hydrogen water? It’s fairly high across the companies manufacturing hydrogen water bottles with PEM technology. But its benefits are higher than the cost of the product and you have control over the water you are using.

You don’t have to worry about the hurdles of getting hydrogen water available to you because they are insignificant compared to the potential benefits. Using hydrogen water daily can potentially keep the doctor away.

Your Take Home

Since the benefits of hydrogen water are very true based on research, there is no better time for you to start enjoying its benefits than now. 

Do the following:

Buy a hydrogen water generator since they are the most affordable option for a long term commitment.

Drink at least 500ml of hydrogen water daily, especially from higher hydrogen concentration brands.

Drink it immediately. If you can’t, don’t store hydrogen water open for more than 2 hours. It will lose your much-needed hydrogen with time. 

Measure the performance of your hydrogen water bottle regularly.

If you choose the high concentration option, go for the reinforced design to accommodate high pressure. This ability is due to its membrane support on the cathode and a thick Glass or Tritan plastic bottle accompanied by an airtight cap.


Hydrogen water is gaining pace in the mainstream American population. While manufacturing companies make huge claims about the product, its benefits are vast and profitable. We believe that you will act from the point of information as you tread confidently as the end-user.
Folks, don’t forget your daily hydrogen water, it’s well worth it.

  1. I appreciate this site. Thank you for your candor. I have have 7 sons who were/are college and high school athletes. I have been researching this product for some time on amazon, but it is definitely hard to determine what reviews are true. We also have a gym at about 4000 feet that certainly affects my college athletes when they come home. It would be interesting to see if this would help their practice performance at home. Even when they come home in season and in shape, it is quickly tiring at this elevation. I just need to decide which ones are real and not just “hype.”

  2. Good day! I just wish to give you a huge thumbs up for your excellent information you have got here on this post. I am coming back to your blog for more soon. Good day!
