No Mixing. No Waiting.

Hydrogen tablets have a problem the marketing skips. Hydrogen is the smallest molecule there is, and the moment it comes out of the tablet it starts leaving the glass. Every second between dissolving and drinking is hydrogen you paid for and never absorbed.

Frequently Asked Questions

When will I notice results with Daily H2?

Most nutritional supplements take 30–60 days of consistent use to show noticeable effects. With Daily H2, some customers have reported feeling a difference in just a few hours—or within the first few days. Individual results vary, since it depends on factors like oxidative stress levels and overall health. For best outcomes, take Daily H2 consistently for at least 30 days.

How does Daily H2 generate Molecular Hydrogen (H2)?

Our proprietary magnesium blend reacts with water in the stomach, donating electrons to hydrogen ions (H⁺) to generate molecular hydrogen (H₂).

Can I use alkaline water or will it cancel out the benefits of the hydrogen pills?

Freshly made alkaline water contains only a small amount of molecular hydrogen (H₂), which is why water ionizer devices can provide some benefits. Daily H2 works perfectly even with alkaline water, since your stomach acid naturally contains enough hydrogen ions (H⁺) for the reaction to occur effectively.

How much hydrogen does Daily H2 generate?

The concentration of H₂ (ppm) depends on the amount of water in your stomach. One capsule of Daily H2 produces approximately:

  • 4.74 ppm in 350 mL of water
  • 3.3 ppm in 500 mL of water
  • 1.65 ppm in 1 liter of water

Customers appreciate this convenient molecular hydrogen supplement for boosting energy, focus, and recovery without the hassle of dissolving tablets or dealing with metallic taste. Many noted improved endurance and mental clarity. The formula includes marine minerals, magnesium, zinc, and selenium. Some found the price steep, and a few experienced no noticeable effects.

Helps with energy

If I am supposed to be dissolving these in water I have not been. I just take two in the morning and off I go. They really do help with energy and focus. I am not sure if they help with hydration, I have not noticed much of a difference. They seem to be effective with working out and walking. Easy to swallow if you don't want to dissolve them in water. The Value for the money is a bit steep but I like them.

Convenient way of including hydrogen in your diet.

I have found that DailyH2 has made incorporating hydrogen water into my routine incredibly easy. The "swallow and go" capsule format truly simplifies the process, completely eliminating the need for mixing, waiting for tablets to dissolve, or dealing with any unpleasant metallic taste.It's been a game-changer for convenience, especially when traveling. I appreciate the fast-acting delivery system directly in the body . I also feel good knowing the product is manufactured in GMP-certified facilities in the USA and uses a clinically inspired formula including marine minerals, magnesium, zinc, and selenium .

Capsule alternative to hydrogen water

I like hydrogenated water, but I've got to admit that sometimes I drop the tablet in a bottle of water and forget that I have to drink it right away.This supplement simplifies that process. You take two capsules once or twice a day and drink lots of water.Hydrogen therapy reduces oxidative stress and inflammation. It's also good for the brain, heart, and liver.I also take NAD+ but mollecular hydrogen is 10 times smaller than NAD so it penetrates cells and mitochondrial for rapid absorption.

Easiest Hydrogen Water Solution

I've been drinking Hydrogen water for a good couple years. Using the electric bottle for the most part and I've tried the tablets that dissolve in about 5 minutes in a glass a water. Both have been excellent feeling water. But they do take that initial 3 to 5 minutes to process.Where these capsules are perfect for the quick swallow and release when I've either spaced or just don't have the time in the morning. Overall I feel the same benefits as the other two. It's quick and easy but I don't get the drink out of it. Which I do enjoy. But I think this one can compliment the other two versions nicely as a good alternative.

Vegan Molecular Hydrogen Capsules

I just started taking the DailyH2 Molecular Hydrogen Capsules. Did I read the direction first? No. It is recommended to take them on an empty stomach, and I didn't follow that advice originally since I didn't read it. Problem corrected. Following the directions provides better results.The recommended serving is 1 to 2 per day with water on an empty stomach. They recommend a quick start of 2 capsules 2 times a day for 2 weeks, so I may try that.

more convenient delivery method

These hydrogen capsules are a little bit unusual. Usually, you are supposed to put hydrogen capsules in a glass or bottle of water, allow to fully dissolve, and then quickly consume that water, which theoretically is now enriched with hydrogen. These recommend that you just take them like a regular pill, on an empty stomach with water. Also, these have a few additional ingredients that you don’t usually find in hydrogen tablets: calcium, zinc, and selenium. These also contain magnesium carbonate. Unfortunately, it also has a few filler ingredients, microcrystalline cellulose, magnesium stearate, and silicon dioxide. These do state that they are GMP certified made in the USA and third-party tested, so I feel like it’s safe to at least try them. I was curious if it would create an upset/gassy stomach similar to taking baking soda or another fizzy object. my stomach did feel a little funny for a little while, but not too bad. Unfortunately, I can’t report that I experienced any boost and energy.

H2 without the bottle

Overall Rating: 4 stars (above average) - This Primonutra H2 supplement is a good option if you want to try molecular hydrogen without a large upfront investmentIndividual Ratings:INGREDIENTS: above average - electrolytes plus 500mg H2 blend. I dislike the use of blends because you don’t know how much of each ingredient you’re getting, which makes it difficult to combine with other supplements.QUALITY: excellent - Made in the USA in a GMP certified facility. 3rd party tested. No indication of country of ingredient origin.USAGE: above average - 2 capsules per serving for a total of 30 servings.Note: Supplements are regulated like foods by the FDA, and claims regarding efficacy often aren't backed by science. So I don't review supplements based on those claims, and instead rate them based primarily on ingredients and quality. Prices and budgets can vary so I usually leave it to the reader to determine value for themselves.

Results even with half dose

I really like these daily molecular hydrogen capsules from PrimoNutra. I started out taking half a dose, one per day instead of two, to make sure there were no adverse effects. Even with a half dose, I've noticed a slight uptick in energy, better bowel movements, and improved cognition. I've also started taking a few other supplements around the same time, but I'm pretty sure this one is contributing to the results I'm getting, as they're consistent with the benefits of this type of supplement. I would definitely recommend this product. I'm moving up to the full two-capsule daily dose. Like me, you might see results with half a dose, but the full dose might be even better - we'll see.

Better Than Tablets

I’ve been using H2 tablets for a while and enjoy the benefits, but I never loved the process of dropping them in water and waiting. I came across this new product at a great price and decided to give it a try. Now, I just take two capsules in the morning before my runs, and I’ve noticed a real difference in my endurance and recovery time. Highly recommend it to anyone looking for a natural boost in energy and performance!

Superior Form Especially For Bones. Maximum Benefit When…

It’s important to take hydrogen water tablets on an empty stomach. This is extremely important for absorption. Research shows that food reduces how much molecular hydrogen your body can utilize. So I take 1 pill first thing in the morning, and the second pill (daily recommended is 2 pills daily) for better energy before working out.Online it says that for better energy, take hydrogen tablets 10-30 minutes before working out. Since the capsule needs to break down to release the H2, I take it a half hour beforehand and it works well.Since I don’t work out every day, I take the second pill mid afternoon when my energy is low and it helps give me a lift.Something I haven’t tried but may be useful for some of you is that it says online that drinking it a couple of hours after dinner may help with overnight recovery and sleep quality. 


Calcium Aquamin F is a highly bioavailable, plant-based mineral supplement derived from red marine algae. It contains magnesium and over 72 other trace minerals. It is Great for bone health and digestive health. So. I’m Super Excited about this combination of ingredients for health!The company that makes this, Prima NUTRA has everything we look for in purchasing safe supplements. You can see those important attributes listed on the left side of the label (second photo).So, I feel very fortunate to have this Highly Effective H2!

Simple enough & pretty clean ingredients

These supplements caught my eye as I've not really seen such a thing before so I researched more on them. The dosage of each ingredient is close enough for some benefits & from my testing I can say I feel some of the benefits listed. I feel a bit more focused but that could be placebo. The speed of recover, gut health, & oxidative stresses are something that would have to be measured clinically and over time. As for the ingredients that support this, the amounts are close to in range. Not too much different than just taking a multivitamin that has it all in my opinion, and as for the 'hydrogen', they don't really list the amount of the ingredient, but they do list the supporting micronutrients.I can say they're easy to swallow, give somewhat a continuation of good energy for given you are taking care of you body correctly, and following the instructions. The ingredients seem to be clean & overall they're good for the sole purpose they intend to help with. I think they're in the range of affordable , but overall I'm happy to know I'm supporting my body with extra nutrients

I like my molecular water...

I don't really like the way it tastes, though, so when I am doing the tablets I always have to either dilute them down with so much water that it takes me a while to drink it or I have to add flavor, which I don't always want. I like these because I can take them with water and not have the taste I don't like.If you're doing molecular hydrogen, this would be a good alternative for you. I like it and haven't noticed a difference between this and the tablets on the days I alternate with this.

5 starsBioavailable mineral boost not just H2I like dailyH2 because it provides a significant source of calcium, zinc, and selenium along with the H2 that we all know and love. It's a well balanced formula that in my opinion is superior to the tablet versions. I tried the suggested loading dose of 2 capsules twice a day and I feel amazing!

WORTH IT

I was really impressed with the noticeable difference in my energy and focus after using DailyH2. I started with the suggested serving and within a couple of days felt a clear improvement in how good I was feeling. Definitely worth a try if you’re looking for a high quality hydrogen supplement.

More energy and happier mood

I used the tablet version of h2 a few times and I noticed a difference in my energy levels. However, I could not get over the metallic taste of it to use it often. When I saw the daily h2 I bought it immediately. I've been taking it for a few days now and I feel amazing! I'm a super busy person with two jobs and a side hustle, but I notice I'm able to stay energized throughout the day and my mood is just SOOO good. I love it, highly recommend it.

Noticeable Energy and Focus Boost Without the Jitters

I’ve been taking the DailyH2 Molecular Hydrogen Capsules for about two weeks now and I can honestly say I’ve noticed a real difference in my overall energy, clarity and recovery. I was curious about molecular hydrogen since I’d heard it supports cellular and mitochondrial health and this supplement has lived up to the hype so far.What stands out most to me is the clean steady energy. It’s not like caffeine or stimulants; just a subtle feeling of being more alert and balanced throughout the day. I also feel like my post workout recovery has improved and I’ve had fewer episodes of brain fog in the afternoon.The capsules are easy to take, vegan and don’t cause any stomach upset which is a big plus. It’s definitely a bit of a unique supplement but I’m glad I gave it a try. So far it's been a great alternative to hydrogen water with real benefits.

A little too early to know

There's a lot of positive research being done into molecular hydrogen, and it's showing a lot of promise, but it's still a little too early to know how much of an effect it has on what, and what side-effects it might have.I was curious though so I've been giving it a try, and I haven't really noticed any changes, positive or negative. But the purported positives are mostly preventative, so it's hard to say.Anyway, there's a little bit of leaking going on in the jar, so there's powder coating everything. but there's no taste to it, so it's fine.
