Hydrogen water might seem like the latest wellness trend, but I’ve actually been drinking it since 2021, back when I worked at Pulsed Ozone, an IV ozone and integrative wellness clinic in Woodstock, Georgia. Back then, it felt like a best-kept secret in the biohacking and detox world. Now, it’s finally getting the mainstream attention it deserves and for good reason.
But truthfully, my journey with hydrogen therapy actually started even earlier.
In late 2020, after dealing with COVID-19 long-hauler symptoms, including scary heart issues and fatigue, I was desperate to find anything that might support my recovery. That’s when I discovered hydrogen tablets, specifically the ones from Dr. Mercola. After just a few days of taking them, I noticed a significant improvement in my energy levels, as if my body had finally received a little boost to start healing.
Whether you prefer H2 tablets or water bottles, hydrogen therapy is now more accessible than ever and well worth a closer look.
What Is Hydrogen Water?
Hydrogen water is simply pure water infused with molecular hydrogen (H₂), the smallest, lightest, and most bioavailable molecule in the universe. It may sound like a buzzword, but molecular hydrogen has over a decade of peer-reviewed research supporting its role as a selective antioxidant that targets harmful free radicals without disrupting beneficial cellular processes.
My Experience with H2 Tablets During Long COVID
In 2020, I was struggling. The lingering fatigue, shortness of breath, heart flutters and sinus tachycardia post-COVID were frustrating and scary. I delved into research on natural tools for mitochondrial repair and immune recovery, and that’s when I discovered molecular hydrogen tablets.
When I started using Dr. Mercola’s H2 tablets, I noticed a clear difference in my daily energy, stamina, and clarity. I didn’t feel like I was dragging myself through the day anymore. That experience is what got me hooked and eventually led me to the hydrogen water machines I now use almost every day.

Hydrogen Water Benefits (Backed by Research)
1. Fights Oxidative Stress and Inflammation
Molecular hydrogen neutralizes harmful hydroxyl radicals, a damaging type of free radical, without interfering with healthy cellular functions.
🧪 A 2012 study showed that patients with rheumatoid arthritis experienced reduced oxidative stress and inflammation after just four weeks of drinking hydrogen-rich water.

2. Improves Energy, Focus, and Cognitive Clarity
Because hydrogen molecules are so small, they easily cross the blood-brain barrier, where they can protect the brain from inflammation and oxidative damage.
🧠 A 2020 study found hydrogen water improved alertness and reduced mental fatigue in healthy adults.

3. Supports Athletic Recovery
Hydrogen water helps buffer lactic acid buildup, reducing post-exercise inflammation and soreness.
🏋️ In a study on elite athletes, those who drank H₂ water recovered faster and reported less muscle fatigue.

4. Boosts Skin Health and Anti-Aging
Hydrogen-rich water may reduce oxidative skin damage, improve hydration, and slow the visible signs of aging. In Japan, hydrogen-infused facials are already a spa staple.
💧 Tip: Pour leftover H₂ water into a spray bottle for a DIY hydrating facial mist!
5. Improves Metabolic and Cardiovascular Markers
Hydrogen water has been shown to help improve blood glucose, cholesterol, and insulin sensitivity in people with metabolic syndrome.
🩺 In an 8-week clinical trial, participants drinking hydrogen water had better lipid profiles and lower fasting glucose.

Tablets or Bottles? Choose What Fits Your Lifestyle
🧴 Hydrogen Tablets
These are single-use, drop-in tablets that release molecular hydrogen when dissolved in water. They’re super portable, great for travel or on-the-go wellness.
- Dr. Mercola’s H2 tablets are my go-to.
- Use with pure water (RO or distilled is best).
- Drink immediately after it dissolves within 1–2 minutes.

🍼 Portable Hydrogen Water Bottles
These bottles generate hydrogen on demand using electrolysis, typically within 3–5 minutes. Perfect for gym bags, road trips, or your desk at work.
- Look for at least 1 to 1.6 ppm, but many new models now go up to 2 ppm or more for better results. Some studies suggest getting 5-8 ppm is most beneficial.
- Use filtered, RO, or distilled water.
- Avoid mineral-heavy tap water to protect the device.
👉 Here’s my recommended portable hydrogen water bottle (1.8 ppm)
👉 Here’s another one that’s a little more expensive but goes up to 6-7 ppm
🏠 2-Liter Home Machine
If you’re sharing with family, a larger countertop machine is a great option.
- Many can produce up to 1.8 ppm H₂, which is ideal.
- Use in glass or BPA-free containers.
- Drink within 15–30 minutes of generating for maximum benefits.

How Long Does the Hydrogen Last in Water?
This is key: hydrogen gas is extremely volatile and escapes quickly from water once it’s generated.
⏱️ Drink within 10–30 minutes for the best results.
✅ Keep your bottle sealed until ready to drink.
❄️ Store cold if you’re not drinking it right away, but aim to consume it fresh.
What Kind of Water Should You Use?
To preserve your hydrogen bottle’s lifespan and effectiveness, use the right kind of water:
✅ Best Choices:
- Reverse Osmosis (RO)
- Distilled Water
- Filtered water with low mineral content
❌ Avoid:
- Hard tap water, especially if high in calcium or chlorine
- Well water, unless filtered
- Anything carbonated or flavored
These can corrode the electrodes and reduce hydrogen output.
Are There Any Risks or Contraindications?
Hydrogen water is generally recognized as safe, even in large amounts. However, a few notes:
- Pregnancy & Breastfeeding: No known issues, but always consult your provider.
- Medications: If you’re on insulin or blood pressure medication, monitor your levels closely. H₂ water can enhance natural metabolic function.
- Implanted Devices: Keep the electrolysis device (not the water itself) away from pacemakers and implants when generating hydrogen.
Quick Guide: How to Use Hydrogen Water Effectively
| Action | Why It Matters |
|---|---|
| Use RO or distilled water | Best conductivity & avoids mineral damage |
| Drink fast | H₂ gas dissipates in under 30 minutes |
| Choose 1000–1800 ppm (minimum) | Higher ppm = more hydrogen benefit |
| Start with 1–2 glasses/day | Increase based on energy & recovery needs |
| Clean your device weekly | Many come with citric acid cleaner |
Kelly’s Thoughts: Is It Worth It?
As someone who’s used hydrogen water for energy, recovery, clarity, and healing, I can say it’s absolutely worth it. Whether you’re recovering from illness, working out daily, or just want a wellness boost that’s backed by science, hydrogen water bottles or tablets are an easy and affordable addition to your routine.
And the best part? No need for a $5,000 machine. Affordable, high-ppm options are now available for everyone.

I’m curious about your recovery from “long covid”. How many shots did you have? How long was your actual covid illness? What symptoms did you have and how long did it take for the hydrogen water to help with your recovery?
Hi Kelly, Thank you for reaching out! I did not have any shots—the vaccines weren’t available yet when I got covid. On day 10 of my illness, I suddenly developed an extremely elevated resting heart rate and ended up being admitted to the hospital several times over the next month. I was put on several medications, but the side effects felt almost as bad as the sinus tachycardia itself.
Hydrogen water was one of the modalities I used to support my healing, but IV ozone was the most helpful. After just 3 treatments I was able to stop the meds, and after 5 I felt almost back to myself. That said, it still took about a year for my adrenals and cortisol levels to settle back into balance after all the trauma. I had severe fatigue during that time… in part from meds, stress and lack of sleep. The hydrogen water would give me energy to get through. : ) I hope that helps!
