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.

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.

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.

Why are they different products, and does the distinction actually matter? It does ⬇️

Both are adaptogens. Both modulate the HPA axis, support stress resilience, and reduce fatigue.

It does.

Adaptogens work through different mechanisms, and matching the right one to the right physiological picture is where the science becomes practical.

🌱 Ashwagandha (KSM-66®, 600mg) - the deeper restoration adaptogen:
→ Restores hormonal balance, regulates thyroid hormones and calms the nervous system via GABA activation
→ Indicated when the stress load has been sustained
→ Think: chronic overload, burnout recovery, sleep disruption, HPA dysregulation

🌱 Rhodiola (Rhodiolife®, 600mg) - the performance adaptogen:
→ Preserves key neurotransmitters, sharpens mental clarity and supports physical endurance under acute stress
→ Indicated for acute mental and physical fatigue
→ Think: high-demand periods, athletic performance, mental fatigue, caffeine-free energy

Both full-spectrum. Both clinically standardised.

Quercus helps you support your body the way it needs.

This Mother's Day, the most meaningful gift might not come in a box.

For many mothers, the hardest part of the day is not the doing but the switching off. The mind that keeps running long after the body is ready to rest.

A five-ingredient complex designed to calm the mind, support sleep onset, and restore natural sleep rhythm without sedation, dependency, and the morning fog.

→ Passiflora incarnata (300mg) - supports easier sleep onset and healthy sleep
→ SereniTea™ L-theanine (250mg) - mental relaxation without drowsiness
→ ETAS®50 asparagus extract (200mg) - stress resilience support
→ Serenzo™ sweet orange peel (150mg) - calming relaxation support
→ Affron® saffron extract (28mg) - positive mood and emotional balance

A meaningful addition for more restful nights, this Mother’s Day and beyond. Because mothers deserve the best.

Curcumin is naturally complex, yet most curcumin supplements are oversimplistic, delivering only one thing: curcuminoids.

The problem is that turmeric root contains two distinct compound families - fat-soluble and water-soluble compounds. A single-extract formula captures therefore only half the picture.

What makes Quercus C³urcumin+® unique is that this formula combines both:
→ Longvida® (400mg) - an optimised curcuminoid complex with 95x greater bioavailability than standard curcumin, detectable in the bloodstream within one hour, and with capacity to cross the blood-brain barrier
→ Turmacin® (500mg) - a water extract of curcuma root standardised to 12.5% turmerosaccharides

Together they support joint health, liver purification via phase II enzyme activation, neurological protection, immune modulation, and healthy skin through complementary mechanisms.

That is what a high-quality full-spectrum supplement delivers. Not a higher dose of the same compound, but genuine full power synergy with broader biological reach.

With adaptogens, the extract determines everything - potency, consistency, and clinical relevance start long before the tablet is made.

Quercus Rhodiola contains Rhodiolife®, a full-spectrum rose root extract sourced from the Altai mountains of Central Asia, harvested in a pollution-free environment and processed to preserve full bioactive integrity.

What that standardisation delivers:
→ ≥3% rosavins - linked to HPA axis modulation and cortisol regulation
→ ≥1% salidroside - associated with neurological protection and neurotransmitter preservation
→ 600mg per tablet - a clinically relevant, high-dose formulation
→ Full-spectrum - natural compound ratios maintained as found in the root

Why does. this level of standardisation matter?
Because rhodiola's adaptogenic effects are compound-dependent. An extract that does not balance the right rosavins and salidroside ratios will not deliver consistent results.

Did you know that 50% of us feel stress at least 3 times per week? That is a lot!

When stress becomes chronic, the problem becomes physiological - it reshapes how the body regulates energy, sleep, and resilience through the HPA axis.

Over time, this dysregulation can lead to:
➛ Persistent fatigue despite rest
➛ Disrupted sleep patterns
➛ Reduced stress tolerance
➛ Impaired cognitive performance
➛ Hormonal imbalances

Usually, we tend towards caffeine, high sugar or caloric foods, and other stimulants to help us get through, but these often have undesired and unhealthy side effects.

So how do you support the body naturally, in a healthy way when under sustained stress? Adaptogens.

Adaptogens such as Rhodiola and Ashwagandha work by helping restore balance within this system:
➛ Modulating the HPA axis and lowering cortisol
➛ Supporting neurotransmitters involved in mood and focus
➛ Enhancing physical and mental resilience
➛ Improving energy production and recovery

Rather than forcing stimulation, adaptogens help the body adapt, bringing it back to a more stable physiological state.

Understanding the HPA axis and the vicious cycle this creates is the first step toward addressing stress at its root.

One of the most searched adaptogen questions is: why should I consider adding ashwagandha to my daily routine?

Simply, because modern life creates a sustained physiological demand that the body was notdesigned to handle indefinitely. Chronic stress, disrupted sleep, cognitive overload, environmental toxins etc. are not separate problems. They share a common root in a dysregulated stress response system.

Ashwagandha helps to regulate this system.

It supports:
➛ Resistance to physical and mental fatigue
➛ Cognitive performance and concentration
➛ Balance within the stress response system (HPA axis)
➛ Sleep quality and recovery

How does it work?
By modulating cortisol levels, supporting GABA receptor activity, and promoting overall physiological balance, it gradually and systemically allows the body to adapt rather than become overwhelmed.

Quercus Ashwagandha contains KSM-66®, a full-spectrum root extract standardised to >5% withanolides, with over 10 years of clinical research behind it.

A plant rooted in tradition, supported by modern science.

Did you know that four types of magnesium taken together are more effective than taking just one?

When it comes to supplements, the form matters, as does the timing of absorption.

Most magnesium products rely on a single source. Quercus MagneRelax® combines four distinct magnesium forms, each absorbed at a different phase in the intestinal tract, for more sustained availability throughout the day.

What are those four sources?
→ ATA Mg® (magnesium acetyltaurinate) - a patented form with affinity for neuronal tissue, supporting brain and nerve function and helping reduce neuronal hyperexcitation
→ Magnesium bisglycinate - well-tolerated, highly bioavailable chelated form, particularly relevant for muscle relaxation and stress-related fatigue
→ Magnesium glycerophosphate - a stable, gentle form supporting energy metabolism and cellular function
→ Aquamin® Mg (magnesium hydroxide from seawater) - a naturally complex mineral matrix with a broad micronutrient profile

For further vitality and energy support, the MagneRelax® formulation also contains active, bioavailable B vitamins in the form of Quatrefolic® (5-MTHF), pyridoxal-5'-phosphate (B6) and MecobalActive® methylcobalamin (B12), ready for direct use in the body.
