🧠 A healthy brain is essential for a healthy life.

Mental clarity and emotional balance rely on finely tuned biochemical communication within the brain. Magnesium is a key mineral in this, supporting neurotransmitter regulation, nerve conduction, and the brain’s response to stress.

MagneRelax® provides a science-backed blend of magnesium and selective B vitamins that work together for our psychological well-being by:
✔ Contributing to reduced fatigue and improved stress resilience
✔ Supporting normal psychological and cognitive functions
✔ Promoting calm and balanced neurotransmission via GABA regulation

By stabilising neuronal activity, magnesium helps the brain maintain focus during the day and unwind in the evening, supporting both mental performance and emotional well-being.

MagneRelax® is designed for today’s fast-paced world, where mental clarity and calm are sometimes hard to find, but quite essential.

Restful sleep begins with a calm nervous system.

Magnesium plays a quiet yet essential role in achieving that nervous system balance that contributes to a healthy mind and body.

It helps:
✔️ Regulate melatonin, the hormone that aligns our internal clock
✔️ Support GABA activity, a neurotransmitter that helps the brain slow down and the body release tension

Together, these processes create the ideal conditions for deeper, more restorative sleep.

When magnesium levels drop, stress hormones can stay elevated, muscles remain tense, and sleep becomes lighter and less refreshing.

Supporting your magnesium status helps restore that natural rhythm, where body and mind can finally unwind.

Quercus MagneRelax® has a synergistic effect, helping you manage daily stress while promoting relaxation at night 😴

Modern life demands both physical energy and mental resilience. Magnesium is central to achieving that balance.

Quercus MagneRelax® combines four different sources of magnesium with taurine, vitamins B6, B12, and folate to form a targeted nutritional complex supporting:
• The proper functioning of the nervous system
• Energy metabolism and muscle performance
• Cognitive and psychological resilience under stress

Why four sources of magnesium? This supports uptake across the gut, resulting in broader absorption and smoother delivery.

A formulation developed for those who need to stay active, composed, and clear-minded, with each nutrient helping the body release tension, sustain focus, and restore calm.

Magnesium plays a vital role in more than 300 enzymatic reactions, influencing energy production, muscle and nerve function, and cardiovascular and bone health.

Despite its importance, suboptimal magnesium levels are common and can develop gradually without obvious symptoms.

❗️Early signs may include:
• Poor sleep quality or fatigue
• Muscle cramps or restless legs
• Headaches or migraines
• Increased irritability or anxiety
• Elevated blood pressure
• Reduced bone density over time

Factors such as stress, ageing, certain medications, and diets low in whole grains, nuts, and leafy greens can increase magnesium loss or reduce absorption.

Maintaining an adequate magnesium intake supports neuromuscular function, cardiovascular balance, and overall metabolic stability. Make magnesium a daily priority for a healthy, energized mind and body.

❕Stress can not only make you feel overwhelmed, but it impacts your entire biochemistry.

When the body is under stress, the adrenal glands release cortisol and adrenaline, preparing you for “fight or flight”. In this state, magnesium is excreted more rapidly from the body. Over time, repeated stress leads to lower magnesium reserves.

But here’s the catch: low magnesium makes the body more reactive to stress. Magnesium naturally calms the nervous system by regulating stress hormones and supporting calming neurotransmitters in the brain. When levels drop, the nervous system stays in a heightened, tense state.

This creates a vicious cycle 🔄Stress depletes magnesium, and magnesium depletion amplifies stress. The result? Irritability, fatigue, muscle tension, and trouble unwinding.

Restoring magnesium balance helps break that cycle, supporting both mental resilience and physical relaxation. Supplementing with Quercus MagneRelax® strengthens the body’s stress-adaptation pathways and promote calm, focused energy.

Vitamin D3 supplementation is often associated with winter, yet its role in human health extends far beyond the colder months.

While sunlight remains the primary natural source of vitamin D3, modern habits such as indoor living, sunscreen use, and limited skin exposure can reduce synthesis even in summer.

Maintaining consistent vitamin D3 intake helps ensure:
✔ Effective calcium absorption for strong bones and teeth
✔ Optimal muscle and nerve function
✔ Continued support of immune regulation

Seasonal sunlight may fluctuate, but your body’s need for vitamin D3 remains constant.

For clean formulation, high bioavailability, and year-round cellular intelligence, choose Quercus Active D₃ forte.

Feeling low on energy or catching every cold that comes your way? It might not just be stress - your vitamin D3 levels could be part of the story.

Vitamin D3's influence goes far beyond bone health. It supports immune cell coordination, reduces inflammation, and plays a role in how your body manages energy and mood.

When levels fall too low:
✔️ The immune response becomes less coordinated, making it harder for your body to fend off infections
✔️ Inflammatory markers rise, leaving you feeling drained or achy
✔️Energy metabolism slows, cells can’t produce or use energy as efficiently, which contributes to fatigue and low mood

Because vitamin D receptors are found in nearly every tissue, deficiency can affect multiple systems at once, often showing up as tiredness, frequent infections, or longer recovery times.

Supporting healthy levels through a high-dose supplement is a simple, evidence-based way to help keep energy, immunity, and overall well-being in balance year-round.

The immune system does not always need boosting; it needs balancing with the right support.

Vitamin D is involved in immunity through several mechanisms and plays a role in regulating both the innate and adaptive immune response in the body.

Here is how this essential nutrient supports your natural defences:
✔️ Regulates immune cell activity - ensuring a quick, measured response to daily challenges
✔️ Promotes immune balance - helps prevent overreaction and supports recovery after illness
✔️ Strengthens first-line defence - maintains the readiness of innate immune cells like macrophages
✔️ Sustains resilience - regulates inflammation and contributes to overall energy and wellbeing when immunity is under pressure

A steady supply of vitamin D3 keeps your immune network balanced and coordinated, helping you stay strong, adaptive, and well-protected throughout the year.
