The specially designed small mouth drinking nozzle of Azeri hydrogen kettle can ensure that hydrogen can be drunk into the body with water, and then converted into an atomic hydrogen, that is, active hydrogen, by human hydrogenase, thus effectively eliminating oxygen free radicals in the human body. It is recommended to drink 500~ 1000 ml of hydrogen-rich water every morning, and gulp as much as possible. In fact, the best time to drink hydrogen-rich water is 0.5~ 1 hour before meals, but it is usually not limited to this. It is also suitable for drinking before going to bed. Normal people suggest drinking about 1.5-2.5 liters a day. Some people suffer from diseases that they can't drink more water, so they need to control the amount of water they drink to be good for their health.
