When it comes to supplements, the source, authentication, and standardisation determine whether it actually delivers.

In Quercus Macu-Vision® why we use Mirtoselect® for exactly that reason.

This premium full-spectrum bilberry extract is the most studied bilberry extract on the market, backed by over 60 positive clinical studies.

Derived from wild Vaccinium myrtillus L. berries harvested in Northern and Eastern Europe, it is standardised to ≥36% anthocyanins and verified by DNA analysis for authenticity and traceability.

In eye health, anthocyanins improve oxygen and blood delivery, support tear secretion, and counteract oxidative stress, a key driver of dry eye and retinal vulnerability.

In Macu-Vision®, Mirtoselect® is combined with Pycnogenol®, DHA, lutein, zeaxanthin, zinc, and antioxidant vitamins C and E to provide comprehensive support for visual function, eye comfort, and long-term eye health.

Trust Quercus to always use the most potent, bio-available, and science-backed ingredients in their supplements.

Three actives. One powerful synergy.

Quercus AstaPure® K2 contrains three nutrients with distinct but complementary roles for immune system health as well as strong teeth and bones.

Why do we combine these three?
→ AstaPure® astaxanthin is a powerful natural carotenoid from Haematococcus pluvialis algae and is one of the most potent antioxidants studied for cellular and cardiovascular protection
→ Vitamin D3 supports normal immune function and calcium absorption, working in direct synergy with K2
→ K2VITAL® vitamin K2 directs calcium into bones and teeth, actively preventing calcification in the arteries and tissues

The D3/K2 partnership is the key mechanism here - vitamin D3 drives calcium absorption, vitamin K2 ensures it reaches the right destination.

Science-based support for daily wellness that our customers love.

Nobody told him to think about his omega-3 levels. But the science around it has been building for years.

EPA and DHA, the two essential active omega-3 fatty acids, support heart function, normal blood pressure, brain health, memory, and concentration. Three things most fathers quietly rely on every single day.

Quercus Omega 3 Forte delivers a high dose of both in their natural r-triglyceride form. This is the structure closest to how omega-3 occurs in fish, which allows for superior absorption compared to ethyl ester forms. Vitamin E has been added for extra cellular protection against free radicals.

Quercus. Helping dads stay active, sharp, and healthy for years to come.

Dry, gritty eyes at the end of a screen-heavy day are not just discomfort. They are a sign that the eye's surface and tear film are under functional stress.

Compounded with age-related changes, environmental stressors, and physiological stress, your eyes can start to struggle.

This is why we developed a formula with ingredients that work at that structural level:
→ MaquiBright® - wild maqui berry from Patagonia; supports natural tear production
→ Sea buckthorn oil - palmitoleic acid, an essential building block of the eye's mucous membranes
→ Biotin - contributes to maintenance of normal mucous membranes
→ Vitamin A from Dunaliella salina - contributes to normal vision

Quercus Macu-Bright® is a clinically studied formula for comprehensive eye support available online and in selected pharmacies.

Did you know that 80% of the billion eye disease cases worldwide could be prevented, treated, or cured?

Most people don't think about their eyes until something is wrong. By then, the window for early intervention has often already narrowed.

Age-related macular degeneration, declining visual acuity, or oxidative damage to retinal cells don't develop overnight. They develop quietly, over years, accelerated by environmental toxins, blue light exposure, poor microcirculation, and insufficient antioxidant protection.

One formula can address all three drivers with impressive results. Quercus Macu-Vision® contains:
→ DHA supports maintenance of normal sight and eye health
→ Lute-gen® lutein & zeaxanthin in a natural 5:1 ratio are macular carotenoids that filter damaging light wavelengths
→ Mirtoselect® anthocyanins & Pycnogenol® OPCs support microcirculation and small blood vessel integrity in the eyes
→ Zinc & Copper contribute to normal vision and eye health
→ Vitamins C & E provide antioxidant protection at the cellular level

Protecting eyesight is not just about seeing well today. It is about preserving your vision for the years ahead.

Lifespan is how long you live.
Healthspan is how well you live for how long.

So how do we increase our healthspan, living not just longer, but better?

The science of resveratrol can shed some light on this.

Resveratrol is one of the most researched polyphenols in the field of healthy ageing. It works at the mitochondrial level, the cell's energy-producing core. By protecting mitochondrial integrity and defending cells against oxidative stress, it addresses one of the primary drivers of biological ageing at its root.

Why does this matter?
→ Mitochondria determine how efficiently cells produce energy
→ Oxidative stress accelerates cellular ageing
→ Vascular health influences both cognitive and physical vitality

Quercus Resveratrol combines three complementary polyphenols for broader, more sustained cellular protection
✔ Veri-te™ trans-resveratrol
✔ Silbinol® pterostilbene
✔ Vitaflavan® grape seed OPCs

Healthy ageing is not about slowing time. It is about protecting your biology and preserving your vitality throughout the years.

Pregnancy is a nutritionally crucial time for mother as well as baby.

This period significantly increases the body's demand for many nutrients, but especially folate for blood formation, nervous system development, and healthy tissue growth in the placenta and womb.

At the same time, vitamin B12 support can help neurological function, mental performance, and reduce fatigue, essential for both mother and baby.

What is cannot be overlooked is the form these vitamins are delivered in.

Non-bioactive forms require enzymatic conversion before the body can use it, a step many cannot complete efficiently.

Quercus Folate B12 bypasses the conversion step by using two bioactive ingredients in its formulation - Quatrefolic®, the bioactive form of folate, and MecobalActive®, a highly pure, active form of B12.

No conversion needed, so the immediate biological availability can work effectively.

Quercus. Looking after this and future generations in a science-based, natural, and sustainable way.

When an elite athlete talks about recovery, it is worth paying attention!

Recovery does not happen during training, but in the hours after. And most critically, during sleep.

Magnesium plays a more central role in this process than is commonly understood. It regulates neurotransmitter release, governs muscle contraction and relaxation, and directly influences how deep and restorative sleep actually is.

Without adequate magnesium, the nervous system stays subtly activated and genuine recovery remains out of reach.

What makes Quercus MagneRelax® clinically relevant here is the formulation logic:
→ Four magnesium sources absorbed in phases for sustained availability through the night
→ Active-form B vitamins supporting nervous system function and reducing fatigue
→ No conversion required as all nutrients are directly bioavailable

Koen Naert recently described exactly this shift in his own recovery: less training, more precision.

The science supports it entirely.

Trust Quercus to bring you science-backed, trusted supplements.

Allergy season is upon us and natural support can make all the difference.

Increased sensitivity during allergy season is a signal that the body's cellular defences are under pressure.

Quercetin is one of the most researched bioflavonoids for cellular as well as immune support, particularly relevant during periods of heightened environmental exposure.

It works by modulating the immune response at the cellular level, helping to reduce excessive reactivity while supporting the body's natural defence mechanisms.

The limitation of most quercetin supplements however is absorption.

How is Quercus QuerCetin forte different?
It solves this absorption issue by using Quercefit®. This quercetin is delivered via Phytosome® technology for up to 20x better absorption than conventional quercetin forms.

The formula also contains PureWay-C®, an optimised vitamin C matrix absorbed faster, more completely, and retained longer in the body, supporting normal immune function and cellular protection.

This synergistic, targeted formula helps support your body in seasons when you need it most.

Feeling off, but can't quite explain why?

Magnesium deficiency is one of the most common yet underdiagnosed nutritional shortfalls.

As its symptoms, such as poor sleep, muscle cramps, headaches, fatigue, irritability, and reduced stress tolerance are easy to attribute to other causes, the connection to magnesium often goes unrecognised.

What makes deficiency so prevalent is straightforward: we do not get enough of it through our diet and the chronic stress we experience. Chronic stress depletes magnesium, and in turn, low magnesium amplifies the stress response. A cycle that compounds quietly over time.

Quercus MagneRelax® addresses this with four complementary magnesium forms, each absorbed at a different phase in the intestinal tract for sustained availability.

Combined with active-form B vitamins all provided in bioavailable forms, MagneRelax® supports both physical and mental resilience.
