Is hydrogen water safe to drink?Generally, yes, hydrogen water is considered safe for consumption.Hydrogen gas is naturally present in the body, and the levels in hydrogen water are typically low. The FDA has classified hydrogen gas as GRAS (Generally Recognized As Safe). However, as with anything new, it's always a good idea to consult with your doctor, especially if you have any underlying health conditions, are pregnant, breastfeeding, or taking medications.
-
Can I use tap water?It is best advised to use CLEAN DRINKING WATER as the quality of water affects the performance and lifespan of the device.
-
How much hydrogen water should I drink per day?The concentration of hydrogen in the water may vary depending on the device and the water used. You may also measure Hydrogen Concentration of the water here
-
How long does the Hydrogen water need to be consumed after generated?The hydrogen gas in water can dissipate over time.It's generally recommended to drink hydrogen water relatively soon after it's generated for the best results. The exact time frame can vary depending on the generator, the container used, and other factors. Check your generator's instructions for specific guidance. Some containers are designed to minimize hydrogen loss.
-
Does hydrogen water taste different?Hydrogen water typically tastes very similar to regular water. It shouldn't have a noticeable taste or odor. Some people might perceive a slight difference, but it's usually very subtle.
Features

Desk top type, compact size, light weight, no power required, easy to carry
DAYS is not only suitable for indoors such as restaurants, bars, but also outdoor activities such as picnics and camping without power supply requirement. It is suitable for both commercial and home use.

Suitable for many people continuous use
This bottle with the dedicated cap is easy to carry, suitable for membership facilities such as gyms, golf clubs, beauty salons, yoga studios and hot spring clubs, etc.

Only takes 3 seconds to finish injection
The purity of hydrogen over 99.9%. Hydrogen concentration can reach 3-10ppm by adjusting the pressure

The secret to high concentration is "pressure"
It is possible to freely set the pressure and change the hydrogen concentration (1.6 ppm to 10 ppm or more).
*MAX 9 atmospheres = 1.6 x 9 = 14.4 ppm is the theoretical value.

Reusable dedicated cap with a check valve
This dedicated cap with a check valve is designed for DAYS. Its small top hole prevents air from entering bottle, keeping the bottle at a high pressure state and maintaining high hydrogen concentration for a longer time

Any beverage
can be filled with hydrogen.
Because it is a direct hydrogen gas filling method, hydrogen can be filled into beverages other than water. Tea and sports drinks can also be made into high-concentration hydrogen beverages.
PERFORMANCE
First in the industry. Hi-Concentration Gas Injection into liquid in seconds
The secret to high concentration is "pressure"

The secret to DAYS's ability to instantly generate high-concentration hydrogen water is the pressure inside the bottle. Simply filling a bottle with hydrogen is no different from bubbling hydrogen at 1 atmosphere, and you cannot expect to dissolve hydrogen at a high concentration.
The special bottle cap has a function to prevent gas from flowing back, so the hydrogen filled in the bottle at 2 to 3 atmospheres is trapped at that high pressure.
As a result, the bottle expands, and hydrogen and water are trapped inside the bottle under high pressure. By utilizing the simple principle that at 2 atmospheres the amount of gas dissolved in liquid is doubled, and at 3 atmospheres the amount is tripled, we have achieved instantaneous high-concentration hydrogen dissolution.
Instantaneous high-concentration hydrogen dissolution has been achieved.

A special PET bottle cap keeps the bottle
filled with hydrogen at a high pressure of 2 to 3 atmospheres .
The check valve in the special PET bottle cap prevents the hydrogen from leaking out and maintains high pressure for a long time, making hydrogen water easy and convenient to drink. It can be used with most domestically produced PET bottled beverages. It is possible to easily dissolve hydrogen in a variety of PET beverages
, including commercially available mineral water, famous water, private brand water, sports drinks, and energy drinks.

CASE

Kanagawa Prefecture Chiropractic Clinic
We are looking for members to fill up with hydrogen water for 1,500 yen per month. We have gained 43 members in the first two months.
Take-home hydrogen water is popular among members.

Kanto area medical corporatio
We have been having our patients undergoing dialysis drink hydrogen water for several years now.
We have finally developed hydrogen water that allows you to consume a large amount of hydrogen with a small amount.
It has also reduced the time and effort required to generate hydrogen water, which has been well received by both patients and staff.

Tokyo, personal training gym
We fill our own brand of water with hydrogen and use it for exercise and yoga. We
have combined high-concentration hydrogen water with exercise. There is also a high demand for takeaway, which is very popular.

Equipment company in Tokyo
We introduced hydrogen water as part of our employee benefits.
Since many of our employees love alcohol and oily foods, everyone drinks it every day under the president's instructions.
We hope to get good results in our next health check.

Salon in Kanagawa Prefecture
We have started a new service that combines hydrogen with the enzyme drinks we offer at our salon.
We are offering a new service that combines enzymes and hydrogen.

Manufacturing company, Kanagawa Prefecture
-
In recent years, the number of employees suffering from mental illness has increased, which has become an issue.
In addition, there are almost no users of welfare facilities, so we were looking for something that would benefit our employees.
We won't know if it will actually be effective until we try it for a few years, but we introduced it to reduce employee stress even a little and prevent them from developing mental illnesses.
Hydrogen Concentration Measurement
Gas Chromatography
DoctorsMan’s hydrogen water products are measured by gas chromatography for accurate performance values.

(Gas Chromatography Tested Through IHSA)
Product development based on accurate measurement
– GAS CHROMATGRAPHY -
When choosing a hydrogen water product, prioritizing performance over price is essential for reaping the antioxidant benefits of molecular hydrogen. Many products vary widely in price and effectiveness, and opting for a cheaper option may not deliver the desired results. To ensure high-concentration hydrogen water, accurate measurement is critical.
Unlike unreliable test solutions that may react with non-hydrogen elements and produce misleading results, Doctors Man hydrogen water products are rigorously tested for performance. We partner with the Japan Molecular Hydrogen Promotion Association (JHyPA) to measure hydrogen concentration precisely using Gas Chromatography, ensuring genuine, high-purity hydrogen water.
The Doctors Man Hydrogen Inhaler is crafted with premium components to deliver safe, high-purity hydrogen gas. Our products are also used in research at medical universities, where Gas Chromatography verifies hydrogen concentration in the blood post-inhalation, confirming accuracy and efficacy.
