Active H® day: Your Cell Protection Complex for Energy, Clarity, and Antioxidative Power
Every day, free radicals attack your cells millions of times: through stress, environmental toxins, modern nutrition, and even normal metabolic processes. These aggressive molecules damage cell membranes, proteins, and DNA, accelerating the aging process. At the same time, your body needs optimal supply of activating minerals for mental alertness and physical energy.
Active H® day combines active hydrogen in colloidal microcluster form with stimulating potassium and synergistic co-factors (silicon, boron, selenium, vitamin B6). Active hydrogen is the world’s strongest antioxidant – it neutralizes free radicals directly at the cellular level before they can cause damage. Patrick Flanagan, the inventor of active hydrogen, puts it succinctly: “1 capsule of Active H® has the antioxidative power of 10,000 glasses of freshly squeezed orange juice.” At the same time, potassium ensures nerve function, energy metabolism, and mental clarity – perfect for active days.
While active hydrogen neutralizes free radicals and reduces oxidative stress, potassium activates your nervous system and provides natural daily energy. Silicon strengthens connective tissue, skin, and vessels, boron supports mineral absorption, selenium protects cells from oxidative stress, and vitamin B6 helps reduce fatigue. All nutrients work synergistically together – for maximum bioavailability and effectiveness.
Thus, Active H® day supports you with antioxidative power at the highest level,
atural daily energy, and cell protection from within. In acid-resistant capsules, 100% vegan, without additives, Made in Germany.
When Active H® day is particularly useful:
- In cases of high oxidative stress (stress, sports, environmental burdens)
- For mental clarity and concentration in everyday life
- With increased energy needs and active days
- To support cell protection and anti-aging
- With vegan or nutrient-poor diets
- For people who want to maximize their antioxidative capacity
Why we developed Active H® day:
Conventional antioxidants often work only on the surface – Active H® day goes deeper. With active hydrogen in colloidal microcluster form, we have combined the world’s strongest antioxidant with stimulating potassium – for cell protection AND natural daily energy in a unique formula.
When thinking of antioxidants, people often focus on Vitamin C or E, but rarely on active hydrogen, colloidal microcluster technology, and the combination with stimulating minerals that make the difference. Active H® day combines the world’s strongest antioxidant with potassium, silicon, boron, selenium, and vitamin B6 – for maximum cell protection AND natural daily energy.
What to look for when purchasing an antioxidant product with a daily energy formula:
Does the product contain active hydrogen or only passive antioxidants?
Is the active hydrogen present in colloidal microcluster form (for maximum stability and effect)?
Are stimulating minerals like potassium included – for energy AND cell protection?
Is the product delivered in enteric-coated capsules (to protect the electron density)?
Is the product free from unstable, volatile compounds?
Does the product contain synergistic co-factors like silicon, boron, selenium, and vitamin B6?
Is the product free from additives, fillers, maltodextrin, stearates, and synthetic ingredients?

Nature does not work in isolation, and neither does your body.
A single antioxidant can neutralize free radicals, but without the right partners by its side, its potential remains limited. Active H® day follows this principle: It combines active hydrogen in colloidal microcluster form with invigorating potassium and synergistic co-factors like silicon, boron, selenium, and vitamin B6. Each nutrient has its own role, but only in combination do they unleash their full power – for maximum cell protection AND natural daily energy. For your body, which deserves complete solutions.
How the nutrients in Active H® day complement each other
Active H® day is more than the sum of its parts. Each nutrient has its own task, but only in combination do they unleash their full power. Here you can see how the synergy team works:
- Active Hydrogen (colloidal microcluster complex): The Cell Firefighter
Active hydrogen is the world’s strongest antioxidant – it neutralizes free radicals directly at the cellular level before they can cause damage. Unlike conventional antioxidants (which can themselves become radicals), active hydrogen donates electrons without becoming unstable. The colloidal microcluster technology ensures maximum stability and effectiveness. Patrick Flanagan: “1 capsule of Active H® has the antioxidant power of 10,000 glasses of freshly squeezed orange juice.” - Potassium: The Daily Energy Activator
Potassium is the crucial mineral for nerve function, energy metabolism, and muscle activity. It ensures that nerve signals are optimally transmitted – for mental clarity, concentration, and physical energy. Potassium is stimulating and activating – perfect for active days. In combination with active hydrogen, it protects your cells while simultaneously keeping your energy levels high. - Silicon (colloidal silicon dioxide): The Structure Stabilizer
Silicon is essential for connective tissue, vessels, skin, hair, and nails. It strengthens the cell structure from within and supports collagen formation. In colloidal form, it is particularly bioavailable and works synergistically with active hydrogen – for cell protection on a structural level. - Boron (sodium tetraborate): The Mineral Optimizer
Boron is a trace element that is often underestimated, yet it plays an important role in the background. It supports the absorption and utilization of other minerals like calcium, magnesium, and potassium. It also promotes bone health and contributes to hormonal balance. Boron works quietly in the background, but without it, the other nutrients would not be optimally utilized. - Selenium (selenium methionine): The Antioxidant Enhancer
Selenium protects cells from oxidative stress and supports thyroid function and the immune system. It enhances the antioxidant effect of active hydrogen and ensures that your body’s own antioxidant system (glutathione peroxidase) works optimally. - Vitamin B6 (pyridoxine hydrochloride): The Energy & Nerve Supporter
Vitamin B6 helps reduce fatigue, supports energy metabolism, and the normal function of the nervous system. It works hand in hand with potassium – for mental clarity, concentration, and stress resistance.
The Master Principle: Synergy instead of Single Substance
Active H® day is not an arbitrary combination – it is a precisely tuned formula for cell protection AND daily energy. Active hydrogen neutralizes free radicals, potassium activates your nervous system, silicon strengthens your cell structure, boron optimizes mineral absorption, selenium enhances the antioxidant effect, and vitamin B6 keeps your energy high. This way, you protect your cells – and stay active, clear, and full of strength.

Product Background:
Active H® day: The World’s Strongest Antioxidant for Cell Protection and Natural Daytime Energy
Do you sometimes feel tired even though you get enough sleep? Do you find it hard to concentrate even though you should be fit? Or do you notice that your body takes longer to recover from stress or exercise? The reason could be oxidative stress – a condition where free radicals attack your cells faster than your body can neutralize them.
This is where Active H® day comes in: With active hydrogen in colloidal microcluster form – the world’s strongest antioxidant – it neutralizes free radicals directly at the source. Combined with stimulating potassium for natural daytime energy and mental clarity, it offers cell protection AND activation in a unique formula.
The Problem: Why Conventional Antioxidants Have Limited Effectiveness
Every day, millions of free radicals are generated in your body – through stress, environmental toxins, modern diet, exercise, and even normal metabolic processes. These aggressive oxygen molecules attack cell membranes, proteins, and DNA, accelerating the aging process, weakening the immune system, and impairing energy production in the mitochondria.
Conventional antioxidants like Vitamin C, E, or OPC can neutralize free radicals – but they have a fundamental problem: When they donate an electron, they themselves become radicals and must be “recycled” by other antioxidants. This limits their effectiveness.
Additionally, many antioxidants do not reach the deeper cell layers where oxidative stress is greatest. They often work only on the surface – not where the “cell fires” actually occur.
The Solution: Active Hydrogen – The World’s Strongest Antioxidant
Active hydrogen is different. As the smallest and most mobile molecule, it penetrates into the deepest cell layers – even into the mitochondria, where 90% of free radicals are generated. There, it neutralizes aggressive hydroxyl radicals (·OH) – the most dangerous of all free radicals – by reacting with them to form harmless water (H₂O).
The special thing: Active hydrogen donates electrons without becoming unstable itself. It does not need to be “recycled” and works immediately, precisely, and without side effects.
Patrick Flanagan, inventor and researcher of active hydrogen, sums it up: “1 capsule of Active H® has the antioxidant power of 10,000 glasses of freshly squeezed orange juice.”
What Makes Active H® day Special: Colloidal Microcluster Technology + Stimulating Potassium
Colloidal Microcluster Technology:
Active H® day uses a patented microcluster technology where active hydrogen is in colloidal form – stable, highly concentrated, and immediately bioavailable. This technology ensures that the electrons are not lost through oxidation but reach the cells with maximum effect.
Stomach Acid-Resistant Capsules:
The special cellulose capsules protect the electron density from the proton-rich stomach acid. This keeps the antioxidant power at the highest level – until the capsules dissolve in the small intestine and the nutrients can be directly absorbed.
Stimulating Potassium for Daytime Energy:
While active hydrogen protects your cells, potassium activates your nervous system, promotes energy metabolism, and ensures mental clarity. Potassium has a stimulating effect – perfect for active days when you want to be focused, powerful, and alert.
Synergistic Co-Factors:
Silicon strengthens connective tissue and vessels, boron optimizes mineral absorption, selenium enhances antioxidant effects, and Vitamin B6 helps reduce fatigue. All nutrients work together – for maximum bioavailability and effect.
What is Active H® day Used For?
Active H® day supports you in many life situations:
- High oxidative stress from stress, environmental burdens, exercise, or intensive work
- Mental clarity & concentration for demanding workdays and mental performance
- Active days & sports for cell protection with increased energy turnover
- Anti-aging & cell regeneration to slow down the aging process
- Immune system support for strong defenses in challenging times
- Vegan diet as a high-quality source of antioxidants and minerals
- Energy deficiency & fatigue for natural daytime energy without caffeine or sugar
Why Cell Protection is So Important for Energy and Vitality
Oxidative stress is not just a “cosmetic” problem; it directly affects your energy production. Free radicals damage the mitochondria (the “powerhouses” of your cells), which are responsible for ATP production (your cell energy). The more oxidative stress, the less energy your body can produce, and the more tired, listless, and vulnerable you feel.
Active H® day protects your mitochondria directly at the source, ensuring that your cells can function optimally. At the same time, potassium activates your nervous system and keeps your mental and physical energy high. The result: cell protection AND daytime energy in one formula.
Active H® day vs. Active H® night: Which Product is Right for You?
Both products are based on the same revolutionary technology – active hydrogen in colloidal microcluster form – but differ in their effects:
Active H® day:
With stimulating potassium for nerve function, energy metabolism, and mental alertness. Perfect for active days, sports, work, and all situations where you want to be focused and powerful.
Active H® night:
With calming magnesium for relaxation, muscle regeneration, and restful sleep. Ideal for evenings to neutralize the oxidative stress of the day and allow your body to regenerate optimally at night.
Active H® day & night (Combo Pack):
The perfect combination – daytime cell protection with activating energy,
ighttime regeneration with relaxing effects. This way, you support your body around the clock.
Active H® day combines the world’s strongest antioxidant with stimulating potassium and synergistic co-factors for cell protection at the highest level and natural daytime energy. In stomach acid-resistant capsules, 100% vegan, without additives, Made in Germany.
FAQ & Frequently Asked Questions about Active H® day and Antioxidants
Active hydrogen (H−) is the smallest and most mobile antioxidant in the world. It penetrates into the deepest cell layers—even into the mitochondria, where 90% of free radicals are generated. There, it neutralizes aggressive hydroxyl radicals (·OH) by reacting with them to form harmless water (H₂O). The special feature: Active hydrogen donates electrons without becoming unstable itself—unlike conventional antioxidants like Vitamin C or E, which become radicals themselves after donating electrons and need to be “recycled.” Patrick Flanagan: “1 capsule of Active H® has the antioxidant power of 10,000 glasses of freshly squeezed orange juice.”
The microcluster technology describes the special form in which active hydrogen is present in Active H® day: as colloidal clusters (microparticles) with the highest stability and electron density. This technology ensures that the electrons are not lost through oxidation but reach the cells with maximum effect. The colloidal form also ensures optimal bioavailability – the active hydrogen is quickly and completely absorbed by the body.
The enteric-coated cellulose capsules protect the electron density of active hydrogen from the proton-rich gastric juice. If the active hydrogen were released in the stomach, the electrons would react with the protons (H⁺) of the stomach acid and lose their antioxidant power. The capsules dissolve only in the small intestine, where the nutrients are directly absorbed, and the antioxidant effect remains at the highest level. At the same time, the acidic stomach digestion is not affected.
Both products are based on active hydrogen in colloidal microcluster form – the difference lies in the activating or calming minerals:
Active H® day:
With stimulating potassium for nerve function, energy metabolism, and mental alertness. Perfect for active days, sports, work, and all situations where you want to be focused and powerful. Consumption: 2 capsules in the morning.
Active H® night:
With calming magnesium for relaxation, muscle regeneration, and restful sleep. Ideal for evenings to neutralize oxidative stress and allow your body to regenerate optimally at night. Consumption: 2 capsules in the evening.
Active H® day & night (Combo Pack):
The perfect combination – daytime cell protection with activating energy, nighttime regeneration with a relaxing effect.
Yes, Active H® day is ideal for sports and high oxidative stress. Intensive physical activity increases oxygen turnover and generates more free radicals – especially in the mitochondria of muscle cells. Active hydrogen neutralizes these radicals directly at the source, thus protecting your cells from damage.
Recommendation for sports:
- 2 capsules daily in the morning (basic supply)
- BEFORE sporting activities, an additional 2 capsules for optimal cell protection during exertion
The stimulating potassium also supports muscle function and nerve signal transmission – for strength, endurance, and recovery.
Active hydrogen works very quickly – the electrons are in the bloodstream within minutes and reach the cells directly. The antioxidant effect thus sets in immediately.
Long-term effects such as improved energy, mental clarity, and regeneration develop over days to weeks – depending on how high your oxidative stress is and how well your body regenerates. Many users report noticeably more energy and clarity after just a few days.
Yes, Active H® day can be easily combined with other dietary supplements. It even enhances the effect of other antioxidants as it supports their “recycling,” for example, active hydrogen regenerates oxidized vitamin C, allowing it to act as an antioxidant again.
Good combinations:
- With Omega-3 (e.g., EyeCQ) for additional cell protection and anti-inflammatory effects
- With MyAMINO for protein supply and muscle protection
- With Vitamin C, E, OPC for synergistic antioxidant effects
Yes, Active H® day is 100% vegan. All ingredients are of plant or mineral origin, and the capsule shell is made of hydroxypropyl methylcellulose (plant cellulose). It contains no animal components, no gelatin, no lactose, no gluten, and no allergens.
One pack of Active H® day contains 60 enteric-coated capsules (45 g). Depending on the consumption amount, one pack lasts:
- With 2 capsules daily (basic supply): 30 days
- With 4 capsules daily (for high stress/sports): 15 days
For continuous supply, we recommend the Combo Pack Active H® day & night – this way you are protected and activated during the day, regenerated and relaxed at night.
No intolerances or side effects are known. Active hydrogen is a natural molecule that the body also produces itself (e.g., through gut bacteria). The dosage in Active H® day is physiological and supports the body’s own defense mechanisms without synthetic additives, without fillers, without unnecessary chemicals.
Yes, Active H® day is designed for long-term use. Oxidative stress occurs daily through metabolic processes, environmental toxins, stress, exercise, and diet. Continuous supply of active hydrogen supports your cells day by day and helps slow down the aging process. Many users have been taking Active H® day daily for years as the foundation of their cell protection strategy.
