Zinc Gluconate
Aquamin®
H2 Blend
Selenium
Zinc Gluconate
Supports immunity and cellular repair.
A cofactor in over 300 enzymatic reactions, playing a critical role in immune regulation, wound healing, and DNA synthesis. Delivered as zinc gluconate for superior bioavailability, it supports the antioxidant defense system alongside the molecular hydrogen generated by DailyH2.*
Aquamin®
72 trace minerals from red algae.
Derived from Lithothamnion calcareum harvested from the North Atlantic. Its naturally porous structure supports superior mineral absorption compared to synthetic sources. A randomized placebo-controlled pilot study found Aquamin supplementation improved joint comfort and mobility scores compared to placebo.*
H2 Blend
World's smallest, most powerful antioxidant.
DailyH2 releases 3mg of molecular hydrogen directly in the stomach. H2 is uniquely able to cross cell membranes — including the blood-brain barrier — to neutralize harmful free radicals at the mitochondrial level. A review of over 51 clinical trials found H2 supports cognitive function, reduces exercise-induced oxidative stress, and improves cardiovascular health markers.*
Selenium
Builds your antioxidant defense network.
Activates 25 essential selenoproteins involved in thyroid regulation, immune function, and the glutathione antioxidant pathway. When paired with molecular hydrogen, selenium supports a layered antioxidant defense for long-term cellular health.*
The Science Behind DailyH2
Oxidative stress damages your cells, your DNA, and your long-term health. In a double-blind, placebo-controlled clinical trial, H2 supplementation reduced every major oxidative stress marker tested — by up to 55%.
How It Works Over Time
Results you can feel in as little as 7 days.*
- Focus and clarity may begin to feel more supported
- Digestion may feel smoother
- Post-workout recovery may feel more supported
- Brain function and focus feel sharper
- Gut comfort improves; less bloating
- Energy feels more consistent after exercise
- Cellular energy and mitochondrial function feel well supported
- Long-term brain and gut health benefit
- Whole-body wellness feels more supported
How to Use:
- Take 3 capsules 1-2 times a day with plenty of water.
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.
Guaranteed results, or your money back
All Primonutra products come with a money back guarantee. If you don't feel a noticeable improvement within 90 days, we'll refund you for your entire purchase.
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
