The Daily Stack

Most people are under-hydrated, under-fuelled, and running on mental fog they have stopped noticing. Not because they are doing anything wrong — but because three of the most fundamental daily habits are the ones most consistently skipped. The Daily Stack fixes all three, simply and cleanly. Bundle price: £69 (and only £58.65 with a subscription)..

HIRO Hydration Electrolyte Tablets

Two effervescent tablets dissolved in water delivers a precise blend of electrolytes to keep you optimally hydrated throughout the day. Not just water — hydration your cells can actually use. Better energy, clearer thinking, fewer headaches, less afternoon fatigue. The difference between drinking water and being hydrated is larger than most people realise. Our tablets bridge that gap, in a format that is genuinely easy to make a daily habit.

HIRO Clean Creatine

3g of 99.5%+ pure micronised creatine monohydrate — nothing added, nothing hidden. Creatine is one of the most extensively researched supplements in the world, and one of the most misunderstood. It is not a gym supplement. It fuels every energy-intensive process in your body — muscle, brain, gut and more. Daily creatine supports mental clarity and focus, lean muscle and everyday strength, faster recovery, and consistent energy without stimulants. Research consistently shows women benefit more than men from supplementing — because women naturally have lower creatine stores to begin with. The uplift is real, measurable, and compounds over time.

SIGNAL

Five clinically studied actives, at meaningful doses, with nothing hidden behind a proprietary blend. SIGNAL is built around Zynamite® and Cognizin® — a fast-acting and longer-term cognitive pairing rarely found together in UK wellness brands. Focus sharpens within 30 minutes, brain fog lifts, and concentration holds through the afternoon without stimulants. Lion's Mane and Korean Ginseng support long-term cognitive resilience, while a full B-vitamin complex — including methylated B12 — keeps the underlying system working as it should. Clear thinking, on a normal Tuesday.

Why they work together

Hydration, creatine and SIGNAL are not three separate routines — they are one system covering the fundamentals most people miss. Creatine relies on adequate hydration to be stored and used efficiently in muscle and brain tissue, so your electrolyte intake directly supports your creatine intake. SIGNAL's cognitive actives work best on a brain that is properly hydrated and properly fuelled — the same foundation creatine builds. Taking all three together is not just convenient. It is better physiology.

Three Products. One Daily Edge.

The Daily Stack+ pairs HIRO Hydration, Clean Creatine and SIGNAL — three evidence-backed daily supplements, combined into one simple routine. Together they support rapid hydration, sustained energy, sharper thinking, and faster mental focus. Backed by science. Built for everyday life.

Rehydrates 4× Faster than Water Alone
Rehydrates 4× Faster than Water Alone

Each tablet contains sodium, potassium, and chloride - the core electrolytes that drive hydration at a cellular level. Together, they optimise water transport through your body so you feel rehydrated faster, not just full of fluid.

Steadier Energy & Focus
Steadier Energy & Focus

Even mild dehydration can impact concentration and mood. With magnesium and potassium supporting nerve and muscle function, HIRO helps sustain steady energy and sharper focus - especially through long afternoons or travel days.

Headaches, Cramp & Fatigue Relief
Headaches, Cramp & Fatigue Relief

Low electrolyte levels are a common trigger for headaches, cramps, and fatigue. HIRO’s balanced mineral mix restores what’s lost through sweat and stress, helping to relieve that heavy, drained feeling.

Cognitive Energy & Mental Clarity
Cognitive Energy & Mental Clarity

Your brain is one of the most
energy-hungry organs in your body. Creatine fuels ATP production beyond muscle - supporting sharper thinking, clearer focus, and mental resilience throughout the day. Research shows creatine supplementation can reduce mental fatigue, particularly during demanding or sleep-deprived periods.

Faster Recovery
Faster Recovery

By replenishing phosphocreatine stores, creatine supports faster recovery between bouts of activity. Less soreness, quicker turnaround, and better output the next day. A compounding benefit that builds with consistent daily use.

Fast-Acting Focus, Powered by Zynamite®
Fast-Acting Focus, Powered by Zynamite®

Most cognitive ingredients work slowly, if at all. Zynamite® is different — shown in clinical trials to activate within 30 minutes, sharpening attention and processing speed for up to 5 hours. No stimulants, no crash.

Less Brain Fog, Powered by Cognizin®
Less Brain Fog, Powered by Cognizin®

Your brain uses around 20% of your body's energy. Cognizin® citicoline supports that demand directly, helping maintain healthy brain cell function and steadier mental energy through the day.

Why Women Benefit More
Why Women Benefit More

Research consistently shows that women have naturally lower creatine stores than men. That means supplementing delivers a more pronounced benefit — more energy, sharper thinking, better recovery, and stronger muscles. Not bulkier. Stronger. These benefits become even more relevant through your 30s, 40s and into perimenopause, when maintaining muscle, mood and mental energy becomes increasingly important.

Long-Term Cognitive Support, From Lion's Mane
Long-Term Cognitive Support, From Lion's Mane

Most ingredients maintain cognitive function. Lion's Mane builds it. Its bioactive compounds stimulate Nerve Growth Factor (NGF), supporting neuron growth, repair and connectivity — a foundation for long-term brain health, not just a daily lift.

HOW TO USE: THE DAILY STACK+

Three products. One daily habit.

Drop two Hydration tablets into approximately 300ml of water, add one scoop of Clean Creatine, stir or shake, and drink. Take two SIGNAL capsules alongside it with water — ideally in the morning or early afternoon as part of the same routine.

Take it any time of day — morning works well as an anchor for the habit. Consistency matters far more than timing. No loading phase needed for creatine — just take it daily and let it build.

Clean Creatine is completely unflavoured and dissolves cleanly, so it will not affect the taste of your Hydration drink. SIGNAL is taken separately as a capsule alongside your drink.

Frequently Asked Questions

About HIRO

HIRO creates premium daily wellbeing products designed to simplify modern nutrition. Our formulations focus on carefully selected ingredients, meaningful dosages and thoughtful formulation.

What is HIRO?

HIRO is a wellness brand focused on creating high-quality daily nutrition products designed to support hydration, energy and overall wellbeing.

Our products simplify complex supplement routines by combining carefully selected ingredients into convenient daily formats.

What makes HIRO different from other supplement brands?

Many supplements focus on long ingredient lists but contain extremely small amounts of each ingredient.

HIRO focuses on carefully balanced formulations that prioritise potency, efficacy and bioavailability rather than simply maximising ingredient count.

Do HIRO products use clinically studied ingredient levels?

Where possible, HIRO formulations aim to reflect ingredient levels supported by scientific research.

This helps ensure ingredients are present at levels designed to deliver meaningful nutritional value.

What does bioavailability mean?

Bioavailability refers to how efficiently nutrients can be absorbed and used by the body.

The form of an ingredient, the surrounding nutrients and the formulation itself all influence bioavailability.

Why not simply include as many ingredients as possible?

More ingredients does not necessarily mean a better supplement.

Many products contain very long ingredient lists but include extremely small amounts of each ingredient.

HIRO focuses on thoughtful formulation and meaningful ingredient levels.

Can I take multiple HIRO products together?

Yes. HIRO products are designed to complement each other as part of a daily wellbeing routine.

How long before I feel the benefits?

Many people begin to notice benefits after 4–8 weeks of consistent use.

Where are HIRO products made?

HIRO products are developed in the United Kingdom and manufactured in European facilities that follow strict quality and food safety standards.

Are HIRO products safe for children?

HIRO products are not recommended for individuals under 18 years of age.

Can I take HIRO alongside medication?

If you are taking prescription medication or have a medical condition, consult your healthcare professional before introducing any new supplement.

Hydration Tablets

HIRO Hydration tablets are designed to support effective daily hydration with a balanced blend of electrolytes.

What are HIRO Hydration tablets?

HIRO Hydration tablets are effervescent electrolyte tablets designed to support effective hydration.

They contain six essential electrolytes that help replenish minerals lost through everyday life, exercise, travel and heat.

Why don't I just drink more water?

Hydration is not only about water intake.

The body also relies on electrolytes such as sodium and potassium to regulate how fluids move in and out of cells.

Adding electrolytes to water can help support more effective hydration during exercise, travel, hot weather or busy days.

Why add electrolytes to water?

Electrolytes help regulate fluid balance, muscle function and nerve signalling.

Maintaining electrolyte balance plays an important role in effective hydration.

Are the hydration tablets vegan and gluten free?

Yes. HIRO Hydration tablets are suitable for vegans and are formulated without gluten ingredients.

When should I take the hydration tablets?

Many customers take hydration tablets:

  • in the morning
  • before or after exercise
  • during travel
  • during hot weather
  • after long days
Are hydration tablets only for athletes?

No. Hydration tablets can support everyday hydration for anyone with an active or busy lifestyle.

How do I take the hydration tablets?

Add two tablets to approximately 300ml of water. Allow them to dissolve fully before drinking.

How many servings are there in each tube?

Each tube contains 20 tablets which provides 10 servings.

Can I just use one tablet?

Yes. One tablet will produce a lighter flavour. However two tablets provide the full intended electrolyte serving.

Why is the serving two tablets?

The formula is designed so two tablets deliver the intended electrolyte balance and flavour profile.

Why does HIRO Hydration contain more potassium than sodium?

HIRO Hydration is designed for everyday hydration rather than extreme endurance sport.

Potassium plays an important role in fluid balance and normal muscle function.

Do the hydration tablets contain caffeine?

No. HIRO Hydration tablets are completely caffeine free.

Do the hydration tablets contain sugar?

HIRO Hydration contains a small amount of glucose which supports electrolyte absorption.

Can I drink HIRO Hydration every day?

Yes. HIRO Hydration tablets are designed for daily use.

Can hydration affect headaches or fatigue?

Mild dehydration can contribute to symptoms such as fatigue and headaches. Maintaining fluid and electrolyte balance can support overall wellbeing.

Can hydration support wellbeing during perimenopause?

Yes. Hormonal changes during perimenopause and menopause can affect how the body regulates fluid balance. Hot flushes, night sweats and disrupted sleep all increase fluid and electrolyte loss, which can contribute to fatigue, headaches and low energy.

Maintaining consistent hydration — with electrolytes, not just water — is a simple and effective daily habit that can support how you feel through this period.

Clean Creatine

HIRO Clean Creatine is pure micronised creatine monohydrate — nothing added, nothing hidden. Unflavoured and ultra-fine, it dissolves easily into any drink and fits seamlessly into your existing routine.

What is HIRO Clean Creatine?

Clean Creatine is 100% pure micronised creatine monohydrate at 99.5%+ purity. No fillers, no flavourings, no sweeteners — just creatine.

It is produced to strict food-grade standards and is suitable for both vegetarians and vegans.

What does creatine actually do?

Creatine is one of the most researched supplements in sports and health nutrition. It helps replenish phosphocreatine stores in the muscles, which supports energy production during short bursts of effort.

Beyond physical performance, research also points to benefits for cognitive function, healthy ageing and general cellular energy.

Will creatine make me look bulky?

No. This is one of the most common misconceptions about creatine — and it puts a lot of women off a supplement that would genuinely benefit them.

Creatine supports lean muscle function and everyday strength. It does not cause bulk. You may notice a very minor, temporary increase in water retention in the first week as creatine stores in your muscle tissue — this settles quickly and is not visible in the way people fear.

What creatine does do is help your muscles work more efficiently, recover faster, and stay stronger over time. The result is a leaner, more toned physique — not a bigger one.

Is creatine only for people who train hard?

Not at all. Creatine supports everyday strength, movement and energy — whether you lift weights, walk regularly, do yoga, or simply want to feel more capable and less fatigued day to day.

It is increasingly recommended for people in midlife and beyond — not because of sport, but because it helps maintain muscle, cognitive function, and stable energy as we age. You do not need to be an athlete to benefit.

How much should I take?

We suggest starting with 3g per day — a level well supported by research for general health and wellbeing benefits. A scoop is included in every pack.

Some people increase this to 5g per day, particularly if they train regularly. There is no need to do a loading phase.

Is a scoop included?

Yes. Every pack of Clean Creatine comes with a measuring scoop so you can dose consistently each day.

How do I take it?

Simply add your scoop to any drink and stir or shake. Because it is unflavoured and ultra-fine, it dissolves easily and does not affect the taste of whatever you add it to.

Can I stack it with other HIRO products?

Absolutely — this is one of the best things about an unflavoured creatine. You can add your daily scoop directly to:

  • Your HIRO Essential Health + Protein Superblend
  • Your HIRO Essential Woman + Collagen Superblend
  • Your HIRO Hydration electrolyte drink
  • Your morning coffee or tea
  • Water, juice or a smoothie

No extra drink needed — it just fits into whatever you already take.

Does it have any taste?

No. Clean Creatine is completely unflavoured. It will not alter the taste, colour or texture of whatever you mix it into.

Is Clean Creatine vegan?

Yes. Clean Creatine is suitable for both vegetarians and vegans.

Does it contain any allergens?

No. Clean Creatine contains no allergens, no gluten, no dairy, no soy, no sugar and no artificial sweeteners or additives of any kind.

Does it contain caffeine?

No. Clean Creatine is completely caffeine free, making it easy to take at any time of day.

When is the best time to take it?

Consistency matters more than timing with creatine. Taking it at the same time each day — morning, pre-workout, or whenever you take your other HIRO products — is the most effective approach.

Do I need to do a loading phase?

No. A loading phase is not necessary. Simply take your daily 3g consistently and creatine stores will build naturally over time.

Is creatine only for people who work out?

No. While creatine is well established in sports nutrition, research increasingly supports its benefits for general energy, cognitive function and healthy ageing — even without a gym routine.

Is creatine safe to take every day?

Yes. Creatine monohydrate has been studied extensively for decades and is widely regarded as one of the safest and most effective supplements available.

SIGNAL Nootropic

SIGNAL is HIRO's advanced daily nootropic — a precise stack of clinically studied ingredients designed to support focus, mental clarity and long-term brain health. Two capsules a day, taken consistently, is all it takes.

What is SIGNAL?

SIGNAL is a daily nootropic capsule formulated to support cognitive performance. It combines five clinically studied active ingredients — Zynamite®, Cognizin®, TheaGreen® L-Theanine, Lion's Mane mushroom and Korean Ginseng — alongside a B-vitamin complex and zinc.

It is designed for anyone who needs sustained mental clarity, sharper focus and better cognitive resilience through demanding days.

What benefits does SIGNAL support?

SIGNAL is designed to support:

  • sustained focus and concentration
  • mental clarity and reduction of brain fog
  • memory and recall
  • calm, alert energy without overstimulation
  • cognitive resilience under pressure
  • long-term brain health
What are the key ingredients in SIGNAL?

SIGNAL is built around five clinically studied active ingredients:

  • Zynamite® (mango leaf extract, 300mg) — supports fast-acting mental energy and focus
  • Cognizin® (citicoline, 250mg) — supports memory, attention and brain health
  • TheaGreen® (L-Theanine from green tea, 167mg) — promotes calm, alert focus
  • Lion's Mane mushroom extract (125mg) — supports neurological health and cognitive resilience
  • Korean Ginseng extract (100mg) — supports mental performance under stress

The formula is completed with Niacin, Vitamin B6, Folate, Vitamin B12, Pantothenic Acid and Zinc — all contributing to normal cognitive and nervous system function.

What makes SIGNAL different from other nootropics?

Most nootropics on the market either rely on caffeine for a short-term lift, or use generic ingredients at doses too low to be clinically meaningful. SIGNAL uses only branded, patented actives — Zynamite® and Cognizin® specifically — at clinically relevant doses, with fully transparent labelling. No proprietary blends, no hidden doses.

Who is SIGNAL designed for?

SIGNAL is designed for anyone navigating a demanding daily life who wants their brain to work at its best consistently. It is particularly well suited to people experiencing brain fog, afternoon cognitive slumps, or difficulty sustaining focus through long days. It is suitable for vegans and vegetarians.

What is Zynamite®?

Zynamite® is a patented mango leaf extract (Mangifera indica) from Nektium, standardised to contain over 60% mangiferin — a naturally occurring polyphenol with well-documented effects on brain function.

Clinical research shows that a single dose produces measurable improvements in attention, processing speed, episodic memory and cognitive flexibility — with effects detectable within 30 minutes and lasting up to 5 hours. Unlike caffeine, Zynamite® works through a different mechanism in the brain, which means it delivers similar alertness and focus without jitteriness, elevated heart rate or the crash that follows a caffeine hit.

It is sustainably sourced as a by-product of mango cultivation.

What is Cognizin®?

Cognizin® is a patented, highly bioavailable form of citicoline from Kyowa Hakko, backed by over 16 years of clinical research. It is the only form of citicoline studied specifically in healthy adults — not just clinical populations.

Citicoline supports the production of phosphatidylcholine (essential for brain cell membrane health), acetylcholine (a key neurotransmitter for memory and learning) and brain energy metabolism. One study found a 13.6% increase in brain ATP in healthy adults after six weeks of daily use.

Notably, research has specifically demonstrated improvements in attention and cognitive performance in middle-aged women — making it particularly relevant for the life stage at which many HIRO customers are taking SIGNAL.

A separate 12-week clinical trial in adults aged 50 to 85 showed meaningful improvements in overall memory, particularly episodic memory. Cognizin® is vegetarian, allergen-free and non-stimulant.

What does Lion's Mane mushroom do?

Lion's Mane (Hericium erinaceus) is a medicinal mushroom with a growing body of research supporting its role in neurological health. It is associated with supporting neurogenesis — the brain's ability to maintain and develop nerve cells — as well as cognitive resilience over time.

Is SIGNAL a stimulant?

No. SIGNAL is not a stimulant. It does not rely on caffeine or stimulant compounds to produce its effects.

Zynamite® supports mental energy through a different mechanism to caffeine, and TheaGreen® L-Theanine actively promotes a calm, focused state. The result is clear-headed focus without jitteriness or a crash.

Does SIGNAL contain caffeine?

SIGNAL contains no added caffeine. The green tea extract (TheaGreen®) used in the formula contributes a negligible trace amount — well below any level associated with stimulant effects.

How do I take SIGNAL?

Take two capsules per day with water. Mid-morning works best for most people — after your natural cortisol peak, when your baseline alertness begins to taper and the ingredients can do the most work.

Each pack contains 56 capsules — a 28-day supply.

When is the best time to take SIGNAL?

We recommend around 11am — after your body's natural morning cortisol peak has begun to taper. This is when many people first feel their focus starting to dip, and the point at which SIGNAL's ingredients can make the most meaningful difference to clarity and concentration through the rest of your day.

How long before I notice results?

Some ingredients in SIGNAL — particularly Zynamite® and L-Theanine — can support focus and mental clarity relatively quickly. Others, such as Cognizin® and Lion's Mane, build their effects progressively with consistent daily use.

Most customers notice meaningful improvements in clarity and cognitive stamina within 2 to 4 weeks. Long-term benefits to brain health and resilience develop over months of consistent use.

Is SIGNAL suitable for daily long-term use?

Yes. SIGNAL is designed as a daily supplement intended for consistent, long-term use. The ingredients are selected to support cumulative cognitive health rather than short-term stimulation.

Is SIGNAL vegan?

Yes. SIGNAL capsules use hydroxypropyl methylcellulose (HPMC) — a plant-derived capsule shell. The formula contains no animal-derived ingredients and is suitable for vegans and vegetarians.

Does SIGNAL contain any allergens?

SIGNAL does not contain any of the 14 major allergens. It is free from gluten, dairy, soy, nuts and artificial additives.

Can I take SIGNAL with other HIRO products?

Yes. SIGNAL is designed to complement other HIRO products as part of a daily wellbeing stack. It works particularly well alongside HIRO Hydration tablets to support both mental and physical performance through the day.

Can SIGNAL help with brain fog?

Brain fog — that feeling of mental cloudiness, slow thinking or difficulty concentrating — is one of the most common reasons people try SIGNAL.

The formula addresses several of the underlying mechanisms associated with cognitive fatigue. Cognizin® supports neurotransmitter production tied to mental clarity. Zynamite® supports alertness without stimulants. Lion's Mane contributes to longer-term neurological resilience. And the B-vitamin complex, particularly B12 and B6, supports normal nervous system function.

Many of our customers are women in their 40s and 50s who notice brain fog worsening through perimenopause. While SIGNAL is not a medical treatment, consistent daily use alongside good sleep and nutrition can meaningfully support mental clarity during this life stage.

Can I take SIGNAL if I am pregnant or breastfeeding?

If you are pregnant or breastfeeding, we recommend speaking with your healthcare professional before introducing any new supplement.

Can I take SIGNAL alongside medication?

If you are taking prescription medication or have a medical condition, consult your healthcare professional before use.

    Very easy to mix

    This dissolves faster than expected and leaves very little at the bottom of the glass.

    Nearly perfect

    Very happy with the powder and the price. I would only change the scoop because reaching the bottom is a bit awkward.

    Mixes well with hydration

    I usually put it in a glass of HIRO Hydration after lunch. It blends well and does not make the drink feel heavy.
