Magnesium is involved in about 600 enzymatic processes in the body. Yet deficiency is one of the most common and most overlooked nutritional shortfalls, partly because its symptoms are so easily attributed to other causes.

What makes MagneRelax® clinically distinct is the formulation logic behind each benefit:

✔ Nervous system: ATA Mg® has a high affinity for nerve cells, helping regulate neuronal activity
✔ Stress resistance: active-form Quatrefolic® (5-MTHF) supports neurotransmitter production and normal psychological function
✔ Energy metabolism: magnesium and active vitamin B12 support normal energy metabolism and help reduce tiredness
✔ Muscles: magnesium regulates neurotransmitter release governing normal muscle contraction and relaxation

A comprehensive, synergistic approach to magnesium support for the demands of modern life.

Why is astaxanthin often called the king of carotenoids?

This is thanks to its exceptional and powerful effect on cellular and thus systemic health.

So, where does it come from?
Astaxanthin is produced by Haematococcus pluvialis, a microscopic freshwater algae cultivated in Israel's Arava desert. Under intense sunlight and environmental stress, the algae naturally produces astaxanthin as its own cellular defence mechanism.

In humans, astaxanthin is one of the most extensively studied carotenoid antioxidants. It helps protect cells and mitochondria against free radicals, supports healthy inflammatory balance, and may help prevent cardiovascular diseases.

In Quercus AstaPure® K2, it works alongside two precisely chosen partners (vitamin K2 and D3) for a powerful synergistic effect.

Three scientifically selected ingredients.
One comprehensive formula for cellular protection, cardiovascular health, strong bones, and immune support.

Why bioactivity matters ➡️

Not all botanical extracts are created equal, and what sets them apart is not only what they contain, but how consistently they perform.

Quercus EnerZen® contains Bluenesse® for this reason. It is a clinically standardised lemon balm extract selected for its biological activity profile.

Standardised to ≥6% rosmarinic acid, its principal marker compound, every batch is also screened for biological activity to help ensure consistent performance.

It works alongside a carefully selected blend of clinically researched ingredients to bring you an optimized EnerZen formula:
→ KSM-66® Ashwagandha for HPA axis regulation, cortisol and thyroid balance
→ Rhodiolife® Rhodiola for acute stress resilience and sustained energy
→ Robuvit® oak extract for caffeine-free energy and recovery support
→ Extramel® SOD to support the body's antioxidant defence

Traditional botanicals, rigorously standardised and clinically researched, form the foundation of a formula designed for reliable, measurable effects.

Available online and in selected pharmacies.

Stress does not only happen in the mind. It also happens in your cells.

Oxidative stress, triggered by environmental exposure, chronic inflammation, poor diet and psychological pressure, generates free radicals that damage cell membranes, lipids and DNA. It is a continuous, low-grade process that accumulates quietly over time.

Quercetin is one of the most researched bioflavonoids for cellular protection. Plants produce it to defend themselves against exactly this kind of environmental stress.

Quercus QuerCetin Forte combines two bioavailable actives:
→ Quercefit® Phytosome® - quercetin with up to 20x better absorption than standard forms
→ PureWay-C® - optimised vitamin C absorbed faster and retained longer than ascorbic acid

Supporting your health starts with supporting your cells.

Vitamin C is often discussed with the immune system in mind, but it also does more for skin health than most people realize.

Vitamin C is an essential cofactor in collagen synthesis. Without it your connective tissue is less resilient, less elastic, and slower to repair.

This applies not just to skin in fact, but to blood vessels, bones, joint cartilage, teeth and gums. Collagen is structural, and vitamin C is non-negotiable for its formation.

At the same time, vitamin C helps protect cells against oxidative stress, keeping them healthier and younger.

Quercus Pure C 1000 is a high dose supplement that delivers 1000 mg vitamin C via PureWay-C®, a combination of vitamin C, fatty acid metabolites, and citrus bioflavonoids that accelerates uptake, extends active time in the body, and improves retention.

Support your skin, immunity, and overall vitality with just one daily tablet.

Folate and B12 are two essential vitamins your body relies on every day. Yet deficiencies are more common than many people realise and they often go unnoticed.

One reason? Not all forms of these vitamins are used equally well by the body.

Many standard supplements contain folic acid and conventional B12, which first need to be converted into active forms before your body can use them. For some people, this process is less efficient.

Quercus Folate B12 contains active, ready-to-use forms of both vitamins: Quatrefolic® (5-MTHF) and MecobalActive® methylcobalamin.

✔ Normal blood formation
✔ Healthy brain and nerve function
✔ Reduced tiredness and fatigue
✔ Mental performance, including concentration, learning and memory
✔ Tissue growth during pregnancy, making it an excellent choice before and during pregnancy

Trust Quercus to deliver high quality, high dose supplements that truly support your body's physiology.

This is why more people are adding resveratrol to their healthy ageing routine 👇

Supporting your health span is about preserving your energy, mobility, cardiovascular health and resilience throughout the years, and resveratrol has become one of the most researched polyphenols in this field.

Resveratrol is a naturally occurring polyphenol found in grapes, peanuts and other plants. In nature, it helps protect plants against environmental stress. In the human body, it helps support healthy ageing by:

✔ Protecting cells against oxidative stress
✔ Supporting healthy circulation and cardiovascular function
✔ Helping maintain normal cellular function and resilience over time

In Quercus Resveratrol forte, we use Veri-te™, a highly purified and clinically researched trans-resveratrol produced through fermentation for exceptional purity and consistency. We combine it with Silbinol® pterostilbene and Vitaflavan® grape seed OPCs to provide broader polyphenol support.

Healthy ageing is not simply about adding years to life but about adding life to those years.

What habits in your daily life contribute to healthy ageing?

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.
