Features： 1、Upgraded Hydrogen Water Bottle: This hydrogen water bottle utilizes advanced technology to quickly generate up to 1600PPB of hydrogen ions in a single cycle, transforming ordinary drinking water into alkaline water rich in hydrogen ions, reducing oxidative stress. 2、Safer: This hydrogen water generator is made of high borosilicate glass, ABS, and aluminum alloy, offering transparency, safety, and healthiness. It adopts special materials for long service life and high hydrogen concentration. The 300ml large capacity meets the needs of the entire family. 3、Benefits: Drinking hydrogen water every day can reduce oxidative stress in the body, thus delaying aging, strengthening the immune system, and boosting metabolism and nutrient absorption. Water is one of the most important foods for the human body, and adding hydrogen to water can enhance its antioxidant properties, which means that it helps improve the ability to increase energy, promotes muscle recovery after exercise, and also improves memory and sleep quality. 4、Useful Tips: For stronger electrolytic effect and higher hydrogen content, it is recommended to use electrolytic water such as sparkling water, alkaline water, and mineral water. Pure water or distilled water may have a relatively lower electrolytic effect. 5、Best Health Gift Choice: This hydrogen water bottle features 1 key operation for convenience. It has a non slip pad at the bottom, providing stability and slip resistance. A great gift to family and friends on birthdays, Thanksgiving, Christmas, New Year, and anniversaries.
