Quick answer

The Winter Defence Set combines several building blocks with vitamin C, zinc, vitamin D, and iron. These nutrients contribute to the normal function of the immune system and to the reduction of tiredness and fatigue, covering important fundamentals for the cold season from several angles at once.

When the days grow shorter, daylight becomes scarce, and heated air keeps rooms dry, everyday life changes noticeably. Many people want to take particularly good care of themselves during this phase, feel fit, and get through winter with a clear head. A well-thought-out Winter Defence Set bundles several building blocks for exactly this purpose that complement each other well: nutrients for the immune system, for energy production, and for general well-being during the dark season. Rather than combining individual products at random, this is about a coordinated concept that covers the fundamentals and accompanies you through winter with a good feeling.

The appeal of a set lies in not having to research and put together yourself which building blocks go well together. The selection follows a shared idea – nourishment during the cold season – and covers several levels in doing so. In this guide, we show you why this combination makes sense right now, what role each product plays, and how to cleverly combine them throughout your day. This turns several products into a well-rounded ritual for the cold season that fits effortlessly into your everyday life.

Why This Combination Works for Winter Defence

Winter challenges the body on several levels. Less sunlight means less of the body's own vitamin D production, cooler temperatures and dry indoor air change everyday life, and many people's perceived energy level drops over the course of the dark months. Anyone who consciously pays attention to their nutrient intake during this time lays a solid foundation. This is exactly where the set comes in: it combines micronutrients with clearly defined, authorised functions into a coherent overall strategy.

Vitamin C, zinc, and vitamin D take centre stage here. Vitamin C contributes to the normal function of the immune system, helps reduce tiredness and fatigue, and protects cells from oxidative stress. Zinc also contributes to the normal function of the immune system and additionally supports the protection of cells from oxidative stress. Vitamin D contributes to the normal function of the immune system and to the maintenance of normal bones, and plays a particularly important role during the low-light months. Iron is also important as it contributes to normal oxygen transport in the body, to normal energy-yielding metabolism, and to the reduction of tiredness and fatigue. These functions work together in winter and form the shared foundation of the set. Rather than relying on a single nutrient, the combination deliberately covers several angles at once – from immune foundations to energy metabolism.

The Products in the Set

Vitamin D3 Depot + K2Pure®

Vitamin D is a classic, especially during the low-light months. Our Vitamin D3 Depot + K2Pure® delivers high-dose D3 combined with vitamin K2 in 180 tablets and is therefore designed for a long period. Vitamin D contributes to the normal function of the immune system and to the maintenance of normal bones, making it a logical starting point for the cold season. The depot form is aimed at anyone who values simple, continuous supplementation.

French Maritime Pine with OPC and Vitamin C

The pine bark extract with 475 mg OPC per capsule, a highly concentrated 25:1 extract, is additionally equipped with vitamin C. Vitamin C contributes to the normal function of the immune system and protects cells from oxidative stress. The plant-based combination partner OPC from French maritime pine rounds off the formula and is made in Germany. This building block thus combines a plant substance with a long tradition with a clearly defined nutrient function.

Iron Bisglycinate + Natural Vitamin C

When energy levels drop in winter, it's worth taking a look at your iron intake. The iron bisglycinate with natural vitamin C relies on a gentle, well-tolerated form of iron that many people find pleasant. Iron contributes to the reduction of tiredness and fatigue as well as to normal oxygen transport in the body, and the natural vitamin C it contains increases iron absorption. Both components thus work hand in hand.

Fadogia Strength Complex with Ashwagandha & Zinc

The Fadogia strength complex with ashwagandha and zinc brings zinc into the set. Zinc contributes to the normal function of the immune system and supports the protection of cells from oxidative stress. The plant extracts fadogia and ashwagandha, both with a long tradition, round off the formula, which is designed as a 10:1 extract with 1,000 mg per daily dose and, with 60 capsules, allows for continuous use.

Glucosamine & Chondroitin with Vitamin C

Cool days mean less outdoor exercise for many people. The glucosamine & chondroitin complex with vitamin C provides additional vitamin C, which contributes to normal collagen formation for the normal function of cartilage. This building block thus adds a facet to the set that's of particular interest to many during the less active season.

Vital Complex with Vitamin C, B6, and Zinc

The lab-tested vital complex with vitamin C, B6, and zinc brings further micronutrients into play. Vitamin B6 contributes to normal psychological function and to the reduction of tiredness and fatigue, while zinc and vitamin C further strengthen the immune foundation. The complex is lab-tested and, with 90 capsules, designed for longer-term use.

How to Combine Them

The easiest approach is to spread the set across the day. Ideally, you take fat-soluble nutrients like vitamin D3 + K2 with a main meal containing some fat, as this supports absorption. Iron bisglycinate pairs well with a vitamin-C-rich meal, since vitamin C increases iron absorption; it's best to keep some time between it and drinks rich in calcium, caffeine, or milk. You can schedule the pine bark extract and the Fadogia strength complex for morning or midday, and take the glucosamine & chondroitin complex and the vital complex spread across the day according to the pack instructions.

A practical approach looks like this: energy- and immune-related building blocks in the morning, plant extracts with a meal at midday, and the remaining capsules in the evening. This way, you spread the active ingredients evenly and keep things easy to track. A small weekly pill box or a fixed spot next to the coffee machine helps you avoid forgetting a dose. In any case, always follow the recommended daily intake stated on each product and don't exceed the stated daily amounts, even if several products contain similar nutrients.

Who the Set Is Suitable For

The Winter Defence Set is aimed at adults who want to take a structured approach during the cold season instead of piecing together individual products. It's especially interesting for people who spend a lot of time indoors, for anyone who notices a lower energy level in winter, and for anyone who already supplements vitamin D, vitamin C, and zinc and wants to combine this with further building blocks. If you only want to cover a single aspect, you can also pick out one building block specifically – but the set offers the advantage that the products are thematically coordinated.

Fundamentals First

As practical as a set is, it doesn't replace a balanced, varied diet or a healthy lifestyle. Simple fundamentals pay off especially in winter: enough sleep, regular exercise including outdoors, drinking plenty of fluids, and as much daylight as possible in the morning. Colourful vegetables, fruit, legumes, and wholegrain products naturally provide many of the micronutrients that the set specifically supplements. Food supplements are intended as a sensible addition, not as a replacement for a good foundation. If you have an existing medical condition, are pregnant or breastfeeding, or are taking medication, please consult your doctor beforehand.

Frequently Asked Questions (FAQ)

Who is the Winter Defence Set suitable for?

The set is aimed at adults who want to consciously pay attention to their intake of vitamin C, zinc, vitamin D, and iron during the cold season. It works as a practical all-round concept if you want to sensibly combine several building blocks instead of putting them together individually. It's also a convenient solution for people who spend a lot of time indoors.

Can I take all the products at the same time?

In principle, combining them is possible. However, it makes sense to spread the products across the day – for example, vitamin D3 + K2 with a meal containing fat, and iron together with vitamin C. Always follow the individual recommended daily intakes and don't exceed the stated amounts, even if several products contain similar nutrients such as zinc or vitamin C.

Why is vitamin D so popular in winter?

During the low-light months, the body produces significantly less vitamin D through the skin because less sunlight is available. Vitamin D contributes to the normal function of the immune system and to the maintenance of normal bones, which is why many people specifically supplement it in winter and value the depot form for continuous supply.

How quickly will I notice something?

Food supplements make their contribution to normal nutrient intake through continuous, regular consumption. A set is designed for daily use over a longer period, not for a short-term effect. A lasting routine throughout the entire winter season matters more than any single day.

Is the set also suitable for vegetarians?

Many of the building blocks rely on plant-based extracts and well-tolerated nutrient forms. Please check the exact details on ingredients and capsule shell directly on the respective product pages, as formulas can vary and suitability differs from product to product.
