What Is Structured Water?
Structured water is most similar to the water found in glaciers and natural springs. Your body absorbs it better, tastes good, supports your heart health, and might even combat cancerous growths.
But are these health benefits of structured water a hoax? Research published in the Oxford Academic Journal of Animal Science found that animals drinking it for a month had better overall health. [1]
They had the following benefits:
- Accelerated growth rate
- Decreased oxidative stress markers
- Improved blood sugar response
- Healthier cholesterol levels
Researchers wanted to confirm these findings and published a paper in the MedCrave Journal of Applied Biotechnology & Bioengineering. They got similar results—but this time in humans. [2] Those who drank vortex water had reduced fat, better kidney function, and improved heart rate variability.
Despite being a new field of research, swirled water shows potential for improving overall health. Even with the skepticism surrounding the 'structured water hoax' allegations, structured water appears to hold substantial health benefits.

How It Works
Through its vortex action, MAYU Swirl oxygenates the water and evaporates chlorine and other VOCs evaporate away. The process results in structured water, which has a unique H₃O₂ molecular formula, which creates hexagonal clusters similar to those you can find in glaciers.
By enhancing the water's taste and texture, MAYU Swirl encourages better hydration. It leads to improvements in overall wellness. The device might also remove chlorine and bacterial buildup.

Is MAYU Swirl Worth It?
Installing a filtration system and repeatedly buying filters is probably more expensive than most people are willing to pay. Other options like a water delivery service or buying cases of bottled water can be problematic as well.
With a single purchase, you can have a beautifully crafted portable device that not only provides water considered to be more beneficial than processed water, you are also reducing plastic and the associated transportation cost.
Clearly, MAYU Swirl is worth it
