Preparing Your Immune System for Autumn and Winter: The Right Nutrients

As the days grow shorter and the thermometer drops, we spend more time indoors, move less outside and get significantly less sunlight on our skin. It is precisely during this phase that it pays to take a conscious look at your own nutrient supply. This guide shows you which nutrients are particularly relevant for the cold season, what to look out for when choosing them and which products from the Scheunengut range are suitable for a well-thought-out preparation for autumn and winter.

The idea behind this is not miracle-cure thinking, but a sober stocktaking: which nutrients typically become scarcer in winter, and how can this gap be sensibly closed? Anyone who answers this question early goes through the cold season far more relaxed than someone who only reacts once the first grey weeks are long under way.

What matters for the goal of immune prep in autumn/winter

At the centre is a solid basic supply of the nutrients that play a role for the immune system. For some vitamins and minerals, official statements are authorised in the EU that describe exactly this connection.

Vitamin D is the classic of the dark season. The body forms it mainly via sunlight on the skin, which in winter is hardly sufficient in our latitudes. According to the EU regulation, vitamin D contributes to the normal function of the immune system and to the maintenance of normal bones. This makes it the obvious first building block for the cold season for many people.

Vitamin C is also one of the nutrients with recognised importance: it contributes to the normal function of the immune system and helps to protect the cells from oxidative stress. Combined with plant compounds such as OPC from pine bark, it fits well into everyday life.

Zinc contributes to the normal function of the immune system and also plays a role in protecting the cells from oxidative stress. It is contained in many combination preparations and sensibly complements the supply.

Iron, finally, also contributes to the normal function of the immune system and, beyond that, to the reduction of tiredness and fatigue as well as to the normal formation of red blood cells. Especially those who feel drained more quickly in winter should keep an eye on their iron status – ideally clarified by a doctor.

Besides choosing the right nutrients, three quality factors matter: a sensible, everyday-suitable dosage, a well-absorbable compound (bioavailability) and continuity – the cold season lasts several months, so the supply should be set up accordingly.

The basic idea of „immune prep“ is simple: instead of only reacting once winter has long arrived, you build up the supply early and keep it consistently stable. The body has no large reserve of water-soluble nutrients such as vitamin C, which is why regular, daily intake is more important than a single high dose. Fat-soluble nutrients such as vitamin D, by contrast, are stored, which explains the depot idea. Anyone who understands these two principles can build up their supply in a much more targeted way.

It is also important to stay realistic: no single nutrient and no preparation makes the body „invulnerable“. What food supplements can do is ensure that the nutrients relevant for the normal function of the immune system do not become scarce – especially in a phase in which sunlight is scarce and the diet can turn out more one-sided due to the season.

Our product recommendations

Vitamin D3 Depot + K2Pure®

For the dark season, the combination preparation of vitamin D3 and K2 is an obvious basis. Vitamin D contributes to the normal function of the immune system and to the maintenance of normal bones, while vitamin K2 complements it with its contribution to the maintenance of normal bones. The depot form with 5,000 IU per tablet is designed for convenient, non-daily intake – practical if you want to be supplied throughout the winter.

French maritime pine 25:1 with 95 % OPC and vitamin C

This pine bark extract provides concentrated OPC plant compounds and is additionally combined with vitamin C. Vitamin C contributes to the normal function of the immune system and protects the cells from oxidative stress. The combination of extract and vitamin makes the product an interesting supplement if you are looking for a plant-based companion with a clear vitamin C contribution during the cold season.

Iron bisglycinate + natural vitamin C

Iron and vitamin C are a proven duo: vitamin C promotes normal iron absorption, and both nutrients contribute to the normal function of the immune system. Iron also supports the reduction of tiredness and fatigue – a topic that concerns many in winter. The chosen compound iron bisglycinate is considered gentle on the stomach and well tolerated, which makes daily intake throughout the cold season easier.

Glucosamine & chondroitin optimised with vitamin C

Those who want to stay active in the cold season despite the cold and move outdoors often think about their joints too. This product combines glucosamine and chondroitin with vitamin C, which contributes to normal collagen formation for the normal function of cartilage – and at the same time supports the immune system in its normal function. A sensible supplement for anyone who wants to keep moving in winter as well.

Basics first

Food supplements are always only one building block – you lay the foundation with your everyday life. In autumn and winter, three things help above all: first, enough sleep, because recovery is the foundation for a resilient organism. Second, exercise in the fresh air, even when it is cold – every walk in daylight counts, precisely because sunlight is scarce. Third, a colourful, varied diet with plenty of vegetables, fruit, pulses and good fat sources, which naturally provides many of the nutrients mentioned.

Supplements come in exactly where everyday life leaves gaps – for example with vitamin D, which can hardly be taken in relevant amounts through diet alone. If you want to know your supply precisely, you can have individual values such as vitamin D or iron determined by a doctor and tailor the supplementation accordingly.

The classic everyday habits also pay into a resilient immune system: thorough hand washing, regular airing of heated rooms and sufficient fluids, because dry heated air strains the mucous membranes. These simple measures cost nothing and complement the nutrient supply ideally. Only the interplay of lifestyle, diet and targeted supplementation makes for a well-rounded preparation for the cold season.

When you put together your range for winter, it pays to start with the building blocks with the clearest seasonal justification – above all vitamin D – and to add the other nutrients according to personal need. This does not create an arbitrary collection of tins, but a consciously built basic supply that fits your everyday life.

An important note: food supplements do not replace a balanced diet or a healthy lifestyle. If you have persistent complaints, are pregnant, breastfeeding or taking medication, please talk to your doctor before taking them.

Frequently Asked Questions (FAQ)

When should I start preparing for winter?

It makes sense to start as early as early autumn, when the hours of sunshine noticeably decrease. That way the basic supply is built up before the darkest time of year begins. Since the cold season lasts several months, continuity is more important than a short-term start.

Which nutrient is most important in winter?

Vitamin D is mentioned particularly often in winter, because the body forms it mainly via sunlight and this is scarce in the dark season. It contributes to the normal function of the immune system. Which nutrients make sense for you personally, however, depends on your diet and your individual needs.

Can I combine several preparations?

In principle yes, provided you observe the dosage recommendations of the individual products and do not supply nutrients unnecessarily twice. Pay attention to how much of a nutrient adds up in total, and stick to the information on the labels.

Isn't a healthy diet enough?

A balanced diet is always the basis. Individual nutrients such as vitamin D, however, can hardly be covered sufficiently through food in winter, which is why targeted supplementation is often sensible here. For other nutrients it depends on your individual habits.

How long should I take the nutrients?

For autumn and winter preparation, the period from about October to March is suitable, i.e. the low-sunlight phase. Some people also supplement individual nutrients such as vitamin D all year round – this can be decided well on the basis of values determined by a doctor.
