FAQ

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.

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.

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.

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.

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.

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

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

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

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

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

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.

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.

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

Maintaining electrolyte balance plays an important role in effective hydration.

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

Many customers take hydration tablets:

• in the morning
• before or after exercise
• during travel
• during hot weather
• after long days

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

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

Each tube contains 20 tablets which provides 10 servings.

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

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

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

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

No. HIRO Hydration tablets are completely caffeine free.

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

Yes. HIRO Hydration tablets are designed for daily use.

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

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.

Essential Woman + Collagen is a daily nutrition blend formulated specifically to support women's wellbeing.

The formula combines hydrolysed collagen, superfoods, adaptogens, vitamins, minerals, probiotics and plant extracts to support multiple areas of health including energy, digestion, skin health and hormonal wellbeing.

Essential Woman is designed to support several aspects of women's health including:

• energy and vitality
• skin, hair and nail health
• digestive wellbeing
• nutritional balance
• hormonal wellbeing

Collagen is the most abundant structural protein in the body and plays an important role in skin elasticity, hair, nails, joints and connective tissue.

Natural collagen production gradually declines with age, which is why collagen supplementation has become popular as part of daily wellness routines.

Collagen works gradually as part of a consistent daily routine.

Many people begin to notice benefits to skin appearance or overall wellbeing after several weeks of consistent use.

Essential Woman contains a combination of nutrients and botanical ingredients designed to support women's wellbeing through different life stages.

Many women incorporate comprehensive nutritional blends into their routine during perimenopause and menopause to help support overall health and vitality.

The formula includes ingredients traditionally used to support women's wellbeing alongside vitamins and minerals that contribute to normal hormonal function.

Balanced nutrition can play an important role in supporting the body through different hormonal phases.

Essential Woman includes probiotics, plant extracts and digestive-support ingredients designed to support digestive wellbeing.

A healthy digestive system plays an important role in nutrient absorption and overall health.

Rather than taking multiple supplements separately, Essential Woman combines complementary ingredients into one daily blend.

The goal is to provide broad nutritional support in a simple, convenient format.

HIRO formulations prioritise meaningful ingredient levels wherever possible.

Rather than adding ingredients purely for marketing purposes, the formula focuses on carefully balanced combinations designed to support potency, efficacy and bioavailability.

Mix one scoop with water, milk or your favourite smoothie once per day.

Most customers take Essential Woman in the morning as part of their daily routine.

However it can be taken at any time of day that fits your schedule.

No. Essential Woman contains bovine collagen and is therefore not suitable for vegans.

No. Essential Woman does not contain added caffeine.

No. Essential Woman is designed to complement a balanced diet rather than replace meals.

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

Yes. Essential Woman is designed to complement other HIRO products as part of a daily wellbeing routine.

Essential Woman is designed for women who want to support their daily nutrition, energy and overall wellbeing with a single, well-formulated daily blend. It is particularly popular with women in their 30s, 40s and 50s who are navigating the physical and hormonal demands of midlife and want a convenient, comprehensive supplement to complement their routine.

Many women find that comprehensive nutritional support becomes especially valuable during perimenopause, when hormonal fluctuations can affect energy, mood, sleep, skin and cognitive clarity.

Essential Woman contains adaptogens, vitamins, minerals and botanical ingredients that are traditionally associated with supporting women's wellbeing through hormonal change. It is not a medical treatment, but consistent daily use alongside a balanced diet can support how you feel through this life stage.

For brain fog specifically, SIGNAL — HIRO's daily nootropic — is designed to complement Essential Woman as part of a complete daily stack.

Essential Health combines plant protein, superfoods, vitamins, minerals, adaptogens, probiotics and digestive enzymes in one daily scoop.

• energy metabolism
• immune function
• digestive health
• muscle recovery
• cognitive wellbeing

Protein supports muscle maintenance and recovery while contributing to overall nutritional balance.

Some supplement products contain long ingredient lists with extremely small quantities of each ingredient.

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.

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.

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.

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.

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.

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

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.

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.

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

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

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

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

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.

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

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.

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

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.

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

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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

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.

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.

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

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

Nootropics are ingredients — plant extracts, nutrients or compounds — that support cognitive function, including focus, memory, mental clarity and brain health.

The term covers a wide spectrum, from well-studied branded ingredients like Cognizin® and Zynamite® through to herbs such as Lion's Mane and Ginseng that have been used for centuries in traditional medicine.

Quality nootropic supplements use ingredients at clinically studied dosages, are transparent about what they contain, and are free from proprietary blends that obscure how much of each ingredient you are actually getting.

Electrolytes are minerals such as sodium, potassium and magnesium that help regulate hydration, muscle function and nerve signalling.

Electrolytes help regulate how fluids move through the body and support hydration.

Superfood powders are concentrated blends of plant-based ingredients designed to support daily nutrition.

The effectiveness of a greens powder depends on formulation quality, ingredient levels and bioavailability.

• ingredient quality
• clinically studied dosages
• bioavailability
• transparent formulation

We do not recommend HIRO to anyone under 18.
