Winter is coming - strengthening the immune system & defences

When it gets cold and wet outside, a cold or a cold is usually not long in coming. A strong immune system helps to protect against attacks from viruses and bacteria.
In addition to exercise, it is important to eat the right food or supplement your diet.

But what exactly does that mean? What does our immune system need to work at its best?
Like the rest of our organism, the immune system also draws its energy from utilisable macronutrients, i.e. protein, carbohydrates and fat. Protein or protein also plays a special role here due to the formation of immune cells.
In addition, the body also needs the right micronutrients in the form of vitamins, minerals, trace elements and other vital substances.

Important micronutrients for the immune system

First and foremost, the antioxidant vitamins A, C and E should be mentioned here:

Vitamin A can bind cell-damaging radicals and is also involved in the formation of mucous membranes and thus the barrier function of the immune system.

Vitamin C is the radical scavenger par excellence, intercepting them and rendering them harmless. Phagocytes (scavenger cells that absorb viruses and other foreign substances) are also dependent on sufficient vitamin C in order to function optimally. A high vitamin C intake also appears to protect against colds and can reduce the duration and severity of a flu-like infection. The requirement is also increased by the use of salicylates such as aspirin.

Vitamin E is also an important free radical scavenger, can protect the body's cells from damage caused by external influences and also ensures that vitamin C is present in its biologically active form.

Vitamin D is also essential in its function as an immune system activator - it can regulate the function of white blood cells.
This vitamin is the only one that can be produced by the body itself - provided there is sufficient UV-B radiation. In our latitudes, UV-B radiation from October to March is unfortunately not enough to produce sufficient vitamin D. As more than 80% of men and 90% of women do not get enough vitamin D from their diet, this leads to deficiency symptoms such as increased susceptibility to infections and depression (winter blues). It is estimated that more than 60% of the population have too low a blood vitamin D level in winter.
This is one of the reasons why the German Nutrition Society quadrupled the reference value for vitamin D intake in 2012.

Finally, minerals such as zinc and selenium as well as secondary plant substances such as bioflavonoids, lutein and lycopene are also important for the functioning of our defences (tip: you can cover your entire daily requirement of zinc with one of our zinc tablets).

The right winter vitamins can therefore strengthen the immune system and prevent colds and infections.
The orthomolecular food supplement Nutri-Plus Immune combines these nutrients in a micronutrient preparation and helps you to stay healthy through the winter. One scoop of powder a day is enough to strengthen the body's defences.
