Frequently Asked Questions

Safety & Medication

Can I take this with my medications?

HydroLabs is just two things: a magnesium-based tablet and the water you drop it into. No stimulants, no caffeine, no proprietary blends — what you're drinking is molecular hydrogen and water.

That said, everyone's situation is different. If you take prescription medication, are managing a health condition, or are pregnant or nursing, talk with your doctor before starting any new supplement — including this one.

Are there any side effects?

The vast majority of our customers experience no side effects at all — it's molecular hydrogen dissolved in water. In rare cases, because the tablet is magnesium-based, some people may notice mild digestive changes, especially at first.

If anything like that happens, stop taking the product and email us at hello@hydrolabs.shop — you'll get an immediate reply and we'll take care of you.‡

What exactly is in the tablet?

A magnesium-based effervescent tablet that releases molecular hydrogen when it hits water. The magnesium generates the hydrogen — the hydrogen is what you drink. No fillers, no proprietary blends, nothing you can't pronounce.

How much magnesium does it contain?

Each tablet contains 40 mg of magnesium, which drives the reaction that releases the hydrogen. The full amount is on the Supplement Facts panel on every box. If you already take a magnesium supplement, keep that in mind — and check with your doctor if you're unsure.‡

Is it right for someone my age?

Very much so. Most of our 200,000 customers are adults over 55 — this is who HydroLabs was built for. One simple tablet in a glass of water once a day. For anything specific to your own health, your doctor knows your situation best.‡

Is This Different?

I've tried a dozen supplements that did nothing. Why is this different?

You're not alone, and you weren't foolish. Most supplements are large molecules your body can barely absorb — they never reach the place where the wear-and-tear happens: inside your cells.

Molecular hydrogen is the smallest antioxidant that exists. It's small enough to slip inside the cell, where everyday oxidative stress — 'cellular rust' — builds up, and help your body respond to it. That's the difference: not a bigger dose, a smaller molecule.†

What does the hydrogen actually do that plain water doesn't?

Plain water hydrates you. It doesn't carry free molecular hydrogen. The hydrogen in H₂O is locked into the water molecule — your body can't use it.

When a HydroLabs tablet fizzes, it releases free molecular hydrogen (H₂) into the glass, and that's what you drink fresh. That free hydrogen is the smallest antioxidant there is — and it's what plain water simply doesn't give you.†

Do you have proof?

Two kinds. First, our tablets are independently tested — an outside lab verified they deliver up to 12 PPM of molecular hydrogen, so it's not just our word. Second, molecular hydrogen has been studied by researchers for decades; you can see that research, with links to the actual studies, on our Science page.

We're confident enough to back every box with a 90-day money-back guarantee — the most honest proof we can offer.†

How It Works

What is molecular hydrogen and why does it matter?

Molecular hydrogen (H₂) is the smallest molecule in existence. Because it's so small, it can go where larger antioxidants can't — inside your cells, where everyday oxidative stress ('cellular rust') collects — and help support your body's natural response to it.†

Size is the whole point. It's not about taking more — it's about reaching the places bigger molecules never do.

Why a tablet in water instead of a capsule or a special bottle?

Because fresh is what matters. Molecular hydrogen works best when you drink it right after it's released, while it's still active. A tablet lets you make it fresh in any glass, anywhere, for about $1 a day.

You don't need a $200 machine or cases of pre-bottled hydrogen water (which starts losing its hydrogen the moment it's sealed). One tablet, one glass, done.

What does “12 PPM, third-party verified” mean?

PPM means 'parts per million' — how much molecular hydrogen is dissolved in your glass. Up to 12 PPM is a high concentration compared to most options out there.

'Third-party verified' means an independent laboratory — not us — measured it and confirmed it. We always pair the two, because a number no one checked isn't worth much.

How soon might I notice something?

Everyone is different. Some people feel a difference in the first couple of weeks; for others it's more gradual as it becomes part of their routine. A daily antioxidant is something you give a fair chance.

That's exactly why we give you 90 days to try it risk-free — enough time to judge it for yourself, not on day one.*

Taste & How To Use

What does it taste like?

You choose. Unflavored is clean — like water with a light, gentle fizz. Raspberry is a soft, natural berry taste, not sugary or syrupy. Both are easy to drink every day, which is the point.

How do I use it?

Drop one tablet into a normal glass of water, let it fizz for a moment, and drink it. That's the whole routine — no measuring, no mixing, no machine.

How many tablets a day?

One tablet a day. Each box has 30 tablets — a full month's supply.

What kind of water should I use?

Normal, room-temperature water works best — not cold. Nothing special to buy; ordinary drinking water is exactly right.

Do I have to drink it right away?

Yes — and that's the advantage. Molecular hydrogen is best fresh, so drink your glass shortly after the tablet finishes fizzing, while the hydrogen is still active. It only takes a moment.

Can I mix it with other drinks or supplements?

For the best result, take it on its own in plain water so you get the hydrogen fresh. It's fine as part of a normal daily routine alongside other things you take — but if you're combining several supplements or medications, check with your doctor.‡

Guarantee & Returns

What's your guarantee?

Every order is covered by our 90-Day Risk-Free Guarantee. Try HydroLabs for a full 90 days. If you don't feel the difference, send it back for a full refund — no questions asked. The risk is ours, not yours.

How do I get a refund?

Email us at hello@hydrolabs.shop within 90 days of your order and we'll take care of it — no hoops, no runaround. You'll get an immediate reply.

What if I only used part of the box?

Completely fine. Even if you've opened a box and used some of it, you're still covered within the 90 days. We'd rather you actually try it than leave it in a drawer.

Subscription & Billing

How does the subscription work?

You choose. Unflavored is clean — like water with a light, gentle fizz. Raspberry is a soft, natural berry taste, not sugary or syrupy. Both are easy to drink every day, which is the point.

When will I be charged next?

Your next charge happens about every 30 days, on the same cycle as your deliveries. You can see and change your next date anytime in your account under 'Manage Subscription.'

Does the price change after my first order?

No. Your price stays the same — the price you sign up at is the price you keep, every box. No hidden jumps, ever.
