What is in a glass of hydrogen water

Water, and molecular hydrogen gas dissolved in it at a few parts per million. Hydrogen water has no calories, sugar or caffeine. With a tablet, the glass also holds what the tablet leaves behind, mainly magnesium and flavor. When you look at hydrogen water side effects, those ingredients are where to look, and the tablet's label should list them.

Magnesium: the part worth checking

Hydrogen water tablets make hydrogen from magnesium. Large amounts of supplemental magnesium can loosen stools, which is why the US National Institutes of Health sets an upper limit of 350 mg a day of magnesium from supplements for adults. Each Clover & Young tablet contains 40 mg. At one tablet a day, that is well under the limit. If you already take a magnesium supplement, add the two together.

Hydrogen water benefits and side effects together

The human trials on record gave people hydrogen-rich water daily for one to four weeks, and some for six months. They measured fatigue, mood and antioxidant markers, and they were small, so they say little either way about long-term use. If you notice anything you don't expect, stop and ask your doctor.

What we put in our tablets

Is it safe to drink hydrogen water every day?

The human studies on record gave people hydrogen-rich water daily for weeks to months. They were small, so if you have a medical condition or take medicines, ask your doctor first.

Ask your doctor before starting hydrogen water or any supplement while pregnant or nursing.

How much magnesium is in a hydrogen water tablet?

What should I do if hydrogen water doesn't agree with me?

Stop taking it and talk to your doctor. Our 90-day guarantee refunds every dollar.

Can hydrogen water cause diarrhea?

Hydrogen itself is a gas dissolved in water. Large amounts of supplemental magnesium can loosen stools, which is why the US National Institutes of Health sets an upper limit of 350 mg a day from supplements for adults.
