If you’re ready to get the most from your Ultimate H2 – including cleaner energy, smoother digestion, and metabolic support – you’re in the right place.

This page is your go-to guide for how to use Ultimate H2, what to expect, and how to stay consistent so you can experience the best possible results from your daily hydrogen-enriched water.†*

Dr. G’s Ultimate H2 Tips

1. Let it fully dissolve, then drink within 5 minutes

Drop 1 tablet into 12–16 oz of room-temperature, non-carbonated water.
As the tablet reacts, it releases a high-potency dose of molecular hydrogen — that’s the fizzing you see.

Cold water slows this process down, so don’t worry if it takes longer. Once the bubbles settle, drink within 5 minutes for optimal hydrogen support.†*

2. Take it around the same time each day

Consistency helps keep your gut and mitochondria stay supported – especially in today’s world of microplastics, processed foods, and disrupted microbiomes.†*
If you miss a day, just resume as usual.

3. Make it a daily ritual

You can take Ultimate H2 once or twice a day – whatever fits your routine. Many people start their day with it for a clean, steady lift… and reach for a second glass later when they want sharper focus without caffeine. What matters most is consistency, since daily use helps support gut lining health, cravings, metabolism, and mental clarity over time.†*

FAQ

What makes Ultimate H2 different?

Ultimate H2 uses a patented tablet technology that releases up to 8 PPM of molecular hydrogen – far higher than standard 1.6-PPM tablets.
It dissolves quickly, tastes refreshing, and includes citicoline, B12, and magnesium to support energy, digestion, and metabolic health from multiple angles.†*

Why isn’t regular water enough?

Regular water contains hydrogen bound to oxygen (H₂O) – not the free molecular hydrogen gas associated with cellular and metabolic support.
Modern life makes things harder: microplastics, pesticides, low-fiber diets, and processed foods can all disrupt natural hydrogen production in the gut.
Ultimate H2 provides hydrogen in a free, bioactive form your cells can actually use.†*

Do I need to drink it quickly?

Yes. Molecular hydrogen evaporates naturally, so for full potency, drink it entirely  within 5 minutes of the tablet dissolving.

Why is my tablet dissolving slowly?

Dissolving time depends on water temperature. In room-temperature water, most tablets dissolve in a couple minutes. In cold water, it can take up to 5 minutes – this is completely normal. Once the fizzing stops, drink it entirely within 5 minutes for the best results.†*

Why does the water taste metallic?

The slight metallic taste comes from the elemental magnesium that reacts with water to release hydrogen. It’s expected – and one reason we added a light berry flavor for a smoother, more enjoyable taste.†*

What if I have metal fillings and feel a sensation?

A small number of people with metal fillings may notice a mild, temporary metallic feeling while drinking Ultimate H2. This is normal and not harmful. If it bothers you, try using a straw or adding more water. 

What should I feel from Ultimate H2?

Everyone’s experience is different. Many people notice clean energy, smoother digestion, or better focus. Others experience more subtle, steady improvements as the days go on. Even if you don’t “feel” something right away, Ultimate H2 is still working behind the scenes to support cellular energy, gut lining health, and natural metabolic function.†*

Is there a money-back guarantee?

Absolutely. Every order is backed by our 90-Day Refund Promise.
