Hydrogen water in Japan, often used to promote longevity and wellness, is highly regarded for its potential antioxidant properties, with hydrogen water ionizers approved by the Japanese Ministry of Health in 2007. Research indicates high hydrogen production in the gut contributes to centenarian longevity, with special aluminum cans maintaining hydrogen concentration for up to five years.

Key Details on Hydrogen Water in Japan and Lifespan:

Longevity Link: Studies suggest higher levels of intestinal hydrogen gas (

) production in Japanese centenarians may contribute to long lifespans by acting as an antioxidant against oxidative stress.

Scientific Backing: In 2007, the Japanese Ministry of Health recognized molecular hydrogen water as a medical device.

Product Lifespan: Specific packaging, such as aluminum cans from brands like H2 WATER JAPAN, can retain high hydrogen concentrations for up to 5 years.

Active Life & Consumption: Molecular hydrogen is a tiny molecule that escapes quickly; in open containers, it evaporates in 15–30 minutes, though it is commonly found in Japanese homes, gyms, and clinics.

Health Research: It is widely recognized for reducing age-related degeneration, combating inflammation, and potentially slowing cellular death

A new study is being touted as showing no relationship between fluoridated water and IQ. But here's what you should know.

The study focuses on a population in Wisconsin that was born in 1940 – which is five years before any communities in the U.S. began fluoridating their water. This is an important limitation because the key window of vulnerability for fluoride's cognitive effects is the early years of life (in utero and infancy) when the brain is undergoing rapid development and the blood brain barrier does not yet adequately protect the baby from toxic chemicals.

Curiously, the authors claim they measured the effect of fluoridation "from birth." This is where it gets interesting.

The authors admit they have no data on water fluoride levels from the 1940s. None. That's a pretty serious limitation by itself. But it gets worse.

To get around this data gap, the authors relied on a 2020 publication that provides test results for about 2 wells per county in Wisconsin. To use this data, the authors needed to make several big assumptions. This is where it gets bad, real bad.

The authors assumed that if ONE well in a county had "optimal" fluoride levels (0.7 mg/L) then EVERY CHILD in that county was exposed to fluoridated water. This assumption, which is critical to the study, has basically no connection to reality. Why? Because the level of fluoride in a single well tells you virtually nothing about the level of fluoride in other wells, let alone in all other wells, let alone in public water supplies (which are often derived from surface waters, not well water).

Why does this matter? Because the study's use of a clearly erroneous measurement of early life exposure to fluoridated water made it virtually impossible for this study to detect an association between early-life fluoride exposure and IQ. It's like trying to determine if prenatal exposure to Tylenol is associated with autism by determining the Tylenol use of the child's neighbor rather than the child's mother.

The dental lobby and the national media are touting a new study that claims fluoride does not reduce IQ.

Problem is the IQ tests in this study were given to high school students in 1956 when they were 16 years old, so they would have been born in 1940.

That is 5 years before the first artificial fluoridation trial in the US had even begun, so not a single person in this dataset had prenatal exposure from fluoridated water, or childhood exposure to fluoridated water from birth to past age 5 years.

Almost all prior studies finding neurotoxicity found it from prenatal or early childhood F exposure. So this study is incapable of assessing whether F is a developmental neurotoxicant.

In fact, 87 studies now show lowered IQ from fluoride exposure (1989 – 2025):

Less than 1% of the population in Japan receives artificially fluoridated water. While water fluoridation was tested in the 1950s and 60s, it is not currently implemented in public water systems. Instead, Japan focuses on topical fluoride application, such as school-based mouth-rinsing programs, with an average natural tap water fluoride level of around 0.09 ppm.

Key Facts About Fluoride in Japan:

No Community Water Fluoridation: Japan does not fluoridate its public water supply.

Eli Lilly’s SSRI, fluoxetine, should never have been approved for use in children — the clinical trials showed the drug was unsafe and ineffective.
