HYDROH
Our Top Pick: The Hydroh Hydrogen Water Tablets (Now $39.99, Was $49.99)
The moment we started testing Hydroh's Tablets, we knew we were dealing with something different.
Immediately first impressions of a nice pouch with a months worth of tablets was convenient. All while being manufactured in the USA which cannot be said with all the tablets we tested. Also having IHSA certificate meaning it is 3rd party tested to dissolve over 8PPM of hydrogen with each tablet.
What truly sets Hydroh apart was how quickly each tablet dissolved and how consistently refreshing these tablets tasted compared to the rest.
Tablets are amazing for convenient and quick daily use that you can incorporate rather easily.
Plus, we've been able to use it as our main daily water bottle thanks to the 15.2 oz capacity.
Plus even I've got my husband to take the tablets and he loves how he's been feeling.
PROS
- IHSA Certificate (3rd Party Tested)
- Consistent 8 PPM+ hydrogen concentration
- Works with any type of water (filtered, tap, or purified)
- Dissolves quickly
- Amazing Taste
- 500+ 5-star reviews
- Zero harmful byproducts
- Clean Ingredient Profile
- If you don’t see any health benefits, Hydroh offers a 90-day money-back guarantee making it basically free
- Convenient pouch perfect for daily use or on-the-go
CONS
- International Shipping takes 5-8 business days
- The flash sale is temporary and stock is limited, may return to $59.99 soon
- Sells out often and have to pre-order and wait months in advanced
- A bit more expensive by $10 (But best tasting tablets)
02
H2TAB
The H2Tab Tablets takes a simple yet effective approach with a box and tablet blister packaging. With claims of 10+ PPM it doesn't have a certificate to back this.
At $29.99, it's priced fair with some of the other tablets we tested. However this may be a bit misleading since there isn't a certificate to validate this claim that our team could find. (Unlike our #1 pick in this article specifically), it's tough to see a reasonable explanation to not choose a supplement that has been tested to do what it's supposed to do!
PROS
- Clean design with tablets in blistered packaging
- More affordable price point
- Subscribe and save $3 per order
- Clean ingredient profile
- Free delivery
CONS
- Lack of certificate to back 10+ PPM claims
- Our box came crushed during shipping so we ordered twice
- International Shipping takes upwards of a 1 month
- 2-week shipping delay
- Slow shipping (2 weeks or more)
The Bottom Line
The Echo Flask focuses on smart features but falls short on practical value.
H2Tab tablets certainly do work but to what degree we're unsure.
With a box crushed during shipping and a bit less convenient way than having a pouch or pill bottle. But made with clean ingredients and tasted fair during our testing.
Given the hype around this brand, we expected better performance fundamentals and experience. Most users want a great tasting and convenient way to implement hydrogen into their daily life.
03
DR. MERCOLA
Dr. Mercola offers 90-tablets in a glass bottle. Through our testing and experience revealed some concerns about overall value and performance metrics.
PROS
- Best price per tablet cost
- 8PPM of Hydrogen
- Soy & Gluten Free
- 90 Tablet Serving (Larger Size)
CONS
- While the glass bottles are great ours fell off the counter and shattered
- Lack of IHSA or independent 3rd party testing
- Higher price point at $49.97
- Dissolves slow during our testing
- Inconsistent taste and made the water at times unpleasant
The Bottom Line:
While Dr. Mercola offers a decent entry point into hydrogen water tablets this price point might be expensive for individuals looking to try hydrogen tablets.
With the added issue of slow dissolving tablets and inconsistent taste this one ranks a bit lower even though the price per tablet is the best.
04
CYMBIOTIKA
Cymbiotika aims to offer affordable price point but makes several compromises to achieve this.
PROS
- More affordable price point
- Gluten & Soy Free
CONS
- Lack of 3rd party testing or IHSA certificate
- Very inconsistent slow dissolving tablets
- Foul tasting compared to others
- Slower shipping time took 9+ days
- Less convenient pill blister packaging
The Bottom Line:
While Cymbiotika Tablets have a more affordable price point we question the effectiveness of the tablets without 3rd party testing.
The extended shipping time and bad tasting tablets make it hard to justify when other options are available.
TOP CHOICE 2025
Our experts award the best value hydrogen water bottle: The Hydroh Tablets
Our Top Pick: The Hydroh Bottle
When we first discovered Hydroh, we were skeptical about their bold claims. A premium choice in molecular hydrogen tablets? We didn't think there could be that much of a difference between brands, almost seemed to good to be true. But after seeing countless positive reviews and their growing reputation in the wellness community, we decided to put it to the test. What immediately stood out was their attention to quality and user experience. Unlike competitors they 3rd party test and certify their tablets and are made in the USA.
The Tablet Experience
What truly sets Hydroh apart was how quickly each tablet dissolved and how consistently refreshing these tablets tasted compared to the rest.

Is this really worth trying? We had the same doubts. However, after seeing their 500+ verified 5-star reviews, their risk-free 90-day trial, we decided to put it through rigorous testing.
