H2TAB Hydrogen Water Tablets with Magnesium – 12 PPM Molecular Hydrogen Tablets for Hydration, Recovery, & Cognitive Support – Vegan, Non-GMO, Gluten-Free – 30 Count (Raspberry)

Advertized at 12PPM in 12-16 ounces of water. I put in 8 ounces and used a reagent test, 30 drops in, and the water was just starting to turn blue. Based on that test, the concentration in 8oz was at least 30 ppm.

I never usually write reviews but this time I had to. ….i really wanted this product to work but after using it for 3 days I had to stop. It was making my teeth feel really weird almost like they were sensitive. And I kept having a weird metallic taste in my mouth. I only used 3 pills but unfortunately there are no returns at all! Shame on me for not investigating that prior to ordering. Anyways I hope this will help future buyers.

This product is amazing. I prefer these over the echo water bottles. I feel so much better in the am!

Not sure what these are supposed to do but i didn't notice any improvements or felling better. Had my friends at work try them and they laughed at how expensive and didn't notice any improvements or feeling better. The package just says magnesium as the ingredients.

First ingredient on the "Other ingredients" list is dextrose. Really??? That's wonderful....if you're looking to feed cancer. Some people are looking to heal themselves of disease not feed it. It is astounding that these companies can take potentially great, healing products and turn them into candy. Stop lacing our supplements with toxins for Pete's sake.

Great for hydration, energy and overall wellbeing. I drink at least one per day if not more.

It didn’t work well for me. It gave me a bloating feeling and if I drink it during the day it makes me sleepy, if I drink before bed I am bloating and sleep bad.

I guess I expected more for the cost. It tasted absolutely terrible. Uniquely gross. I didn't really notice anything crazy after drinking it a few times. It just taste so bad.
