Not medical advice

The information on this website, including our product pages and research articles, is for general education only. It isn't medical advice and isn't a substitute for advice from a doctor or other qualified health professional.

About our products

These statements have not been evaluated by the Food and Drug Administration. OG Hydro products are not intended to diagnose, treat, cure or prevent any disease.

About the research we share

Our research articles summarise published studies in plain English. Many of them were small, short or done in cells or animals, and we say so in each article. A study finding something isn't proof that a product will do the same for you, and individual results vary.

Check with your doctor first if you

  • are pregnant or nursing
  • are taking any medication
  • have a medical condition, including kidney problems
  • are buying for someone under 18

Using the hydrogen tablets

  • Drop one tablet into a glass of water and let it dissolve. Don't swallow the tablet whole.
  • Each tablet contains 80 mg of magnesium. It counts toward the 350 mg a day upper limit for supplemental magnesium for adults set by the US National Institutes of Health, so check any other supplements you take.
  • Use as directed on the label, keep out of reach of children, and don't use if the safety seal is broken.

Using the bottle

Fill the bottle with clean drinking water only, and follow the instructions that come with it. Don't use it with other drinks.
