This $300 rechargeable bottle makes healthy hydrogen water

Step aside, Stanley.

Hydrogen water has been gaining traction in wellness circles for years, embraced by biohackers, athletes and longevity enthusiasts chasing extra health benefits in every sip.

Now, instead of stocking up on cans and pouches, fans can make it themselves using a smart water bottle that infuses regular H2O with molecular hydrogen gas in minutes — even if the cost isn’t exactly refreshing.

Priced at $299.99, the latest Echo Flask made a splash at the 2026 Consumer Electronics Show in Las Vegas this month, drawing crowds to the sleek, rechargeable device.

It’s an upgraded version of Echo Water’s previous bottle, which has been endorsed by celebrities including musician Pharrell Williams, boxer Jake Paul and human biologist Gary Brecka.

The high-tech water bottle is Wi-Fi enabled, syncing with a free companion app that lets you set hydration targets and track your progress in real time. Its battery lasts for about five to seven hydrogen generation cycles on a single charge.

While staying hydrated is essential, proponents say the added hydrogen takes the benefits of drinking water a step further, boosting energy, speeding recovery, improving performance and even slowing the aging process.

“The gas is critical because it can penetrate your cellular layer, where regular water can’t,” explained Alex Koritz, head of corporate communications at Echo Water. He noted that the technology used to create hydrogen-rich water in the flask was initially developed by NASA scientists.

I’ve been using the Echo Flask for the past week, and it’s too soon to tell whether the smart bottle delivers on its extra health benefits. Clinical studies often show noticeable effects from hydrogen water only after four to 12 weeks of regular use.

Still, the Echo Flask’s built-in reminders on its touch screen display nudging me to drink have actually helped me meet my hydration goals over the past few days — something this coffee-and-juice lover has long struggled with.

And I’m optimistic enough to keep going. After all, a growing body of research, including more than 200 human studies, suggests hydrogen water may help reduce oxidative stress in the body.

This imbalance of free radicals and antioxidants can damage cells and tissues, triggering chronic inflammation and harming DNA and proteins.

Over time, it’s believed to accelerate aging and contribute to chronic illnesses such as Alzheimer’s, heart disease, arthritis, diabetes and even cancer.

By countering oxidative stress, hydrogen water may help reduce inflammation, fatigue and metabolic issues, while potentially boosting endurance, brain function, gut health, cardiovascular health and even the appearance of skin.

For people undergoing treatments like radiation therapy, studies suggest that six weeks of hydrogen-rich water can ease side effects such as nausea, headaches and hair loss. One study of cancer patients also reported improved mood and reduced anxiety.

It’s no surprise the trendy beverage has been popular in Asia for decades, with interest growing in North America and Europe in recent years.

In Japan, people have been drinking it since at least the 1960s and also use it in other formats for health purposes, including baths for skin complexion and saline IVs to treat infections.

Dr. Nicholas Perricone, a nutritionist and dermatologist who sells his own hydrogen-rich water and is not affiliated with Echo, previously told The Post that the beverage is “going to change the world.”

“If we can get this country drinking hydrogen water on a regular basis, we could lower our health care costs by a third,” he said.

Hydrogen water is generally recognized as safe (GRAS) by the FDA, meaning it’s approved for human consumption and not known to cause harm.

However, experts caution that very high intake can cause mild digestive issues, such as bloating or loose stools, so it’s best to introduce it gradually.
