Introduction
Our immune system is a fascinating defense network of specialized cells, tissues, and organs that protects us daily from countless pathogens. White blood cells act as our body's own defense army. For these defense cells to work optimally, they need an adequate supply of essential nutrients – especially vitamins and trace elements.
In this comprehensive article, you will learn which vitamins could strengthen your immune system, how vitamins and antioxidants contribute to defense, and how you can use targeted Nutraceuticals how you can especially support your immune defense during cold season. Discover scientifically based strategies to sustainably strengthen your immune system.
Why vitamins are indispensable for your immune system
Your immune system works around the clock to protect you from pathogens. It recognizes harmful invaders like viruses, bacteria, and fungi and fights them before they can cause greater harm. For this demanding task, it needs sufficient "fuel" in the form of various nutrients.
Vitamins play a crucial role. They act as cofactors for numerous biochemical reactions essential for immune function. A deficiency in certain vitamins could significantly impair your body's ability to fight infections.
Vitamin C: The classic among immune boosters
When it comes to supporting the immune system, vitamin C is probably the best-known nutrient. For good reason: vitamin C could influence several aspects of innate and adaptive immunity.
How vitamin C could support your immune system:
-
Strengthening the skin barrier: Vitamin C contributes to collagen production, which could support the structural integrity of your skin – the first line of defense against pathogens.
-
Promoting immune cell activity: It could improve the mobility and function of neutrophils, lymphocytes, and phagocytes – all important cells of your immune system.
-
Antioxidant effect: As a strong antioxidant, vitamin C could protect your cells from oxidative stress caused by the immune response.
Natural sources of vitamin C:
-
Citrus fruits (oranges, lemons, grapefruits)
-
Kiwis
-
Berries (especially strawberries)
-
Bell peppers (especially the red variety)
-
Broccoli
-
Brussels sprouts
-
Potatoes
The recommended daily dose for adults is about 95-110 mg. A healthy, balanced diet with plenty of fresh fruits and vegetables should easily provide this amount.
Vitamin D: The sunshine vitamin for your immune defenses
Vitamin D holds a special position among immune vitamins. Unlike most other vitamins, your body can produce it itself – but only with sufficient sunlight exposure on the skin. Especially in northern regions and during the winter months, endogenous production might not be sufficient.
The immunological significance of vitamin D:
1. Regulation of the immune response: Vitamin D could influence both the innate and adaptive immune response and contribute to a balanced reaction.
2. Production of antimicrobial peptides: It could promote the production of endogenous antibiotics, so-called antimicrobial peptides.
3. Inflammation modulation: Vitamin D could suppress excessive inflammatory reactions and thus protect against immune-related tissue damage.
Natural sources of vitamin D:
-
Sunlight (the most important source)
-
Fatty fish (salmon, mackerel, herring)
-
Egg yolk
-
Mushrooms (in smaller amounts)
-
Fortified foods
It can be difficult to meet vitamin D requirements through diet alone. Especially in the winter months and for people with little sun exposure, supplementary intake might be advisable. The German Nutrition Society recommends a daily intake of 20 µg (800 IU) for adults in case of insufficient endogenous production.

Vitamin A: Supporter of healthy mucous membranes
Vitamin A is a fat-soluble vitamin that occurs in two forms: as retinol in animal foods and as provitamin A (carotenoids) in plant foods. It could play a central role for your immune system, especially in maintaining healthy mucous membranes.
How vitamin A could support your immune system:
-
Maintenance of mucosal integrity: Vitamin A may help maintain healthy mucous membranes that serve as a physical barrier against pathogens.
-
Promotion of antibody production: It may support the production of antibodies important for the adaptive immune response.
-
Regulation of immune cell function: Vitamin A may influence the function of various immune cell types and contribute to a balanced immune response.
Natural sources of vitamin A:
-
Liver
-
Butter
-
Full-fat dairy products
-
Eggs
-
Orange and yellow vegetables (carrots, sweet potatoes, pumpkin)
-
Dark green leafy vegetables (spinach, kale)
The recommended daily dose is about 0.8-1.0 mg retinol equivalent for adults. However, caution is advised with vitamin A, as excessive intake, especially in the form of supplements, can be toxic. Particularly during pregnancy, vitamin A intake should be discussed with medical professionals.
You can find vitamin A with high bioavailability in Opti Immun® capsules from Nutrador®.
B vitamins: The underestimated helpers
The group of B vitamins includes eight water-soluble vitamins involved in numerous metabolic processes. Although they often receive less attention than other immune vitamins, some B vitamins could play an important role in the optimal function of your immune system.
Particularly relevant for your immune system could be:
Vitamin B6 (pyridoxine)
Vitamin B6 could be involved in the production of antibodies and cytokines – molecules important for communication between immune cells. A deficiency could impair the immune response.
Natural sources:
-
Legumes
-
Whole grain products
-
Nuts and seeds
-
Bananas
-
Poultry
-
Fish
Vitamin B9 (folic acid)
Folic acid could be important for cell division and proliferation, including that of immune cells. An adequate folic acid level could therefore contribute to maintaining normal immune function.
Natural sources:
-
Dark green leafy vegetables
-
Legumes
-
Whole grain products
-
Nuts and seeds
-
Citrus fruits
Vitamin B12 (cobalamin)
Vitamin B12 could support the normal function of immune cells. A deficiency could be associated with reduced immune function.
Natural sources:
-
Animal products (meat, fish, eggs, dairy products)
-
Fortified plant-based foods (for people who follow a vegan diet)

Vitamin E: Antioxidant power for your cells
Vitamin E is another fat-soluble vitamin with potentially important immunological functions. As a strong antioxidant, it could protect your cells, including immune cells, from oxidative damage.
How vitamin E could support your immune system:
1. Cell membrane protection: It could protect the cell membranes of immune cells from oxidative damage, thus preserving their functionality.
2. Promotion of T-cell function: Vitamin E could improve the function of T cells, which are important for cell-mediated immunity.
3. Inflammation modulation: It could regulate excessive inflammatory reactions and thus contribute to a balanced immune response.
Natural sources of vitamin E:
-
Nuts and seeds (especially sunflower seeds, almonds)
-
Plant oils (sunflower oil, olive oil)
-
Avocados
-
Whole grain products
-
Dark green leafy vegetables
The recommended daily dose for adults is about 12-15 mg alpha-tocopherol equivalent. A varied diet with unsaturated fats from nuts, seeds, and high-quality oils could contribute to adequate supply. In case of vitamin E deficiency, supplementation could help.
The Opti Immun® capsules from Nutrador® offer you high-quality vitamin E.
The right combination makes the difference
While each individual vitamin could fulfill important functions for your immune system, it is the balanced supply of all essential nutrients that makes the difference. Vitamins often work synergistically – that is, they support each other in their effects.
For example, vitamin C could improve the absorption of iron, which in turn is important for various immune functions. Vitamin D and vitamin A could jointly regulate the production of antimicrobial peptides. The antioxidant effects of vitamin C and vitamin E could enhance each other.
Natural sources vs. supplements
The question of whether natural foods or supplements are the better source for immune-supporting vitamins is often debated. The answer is not clear-cut and depends on various factors.
Advantages of natural food sources:
1. Complex nutrient composition: Natural foods contain not only vitamins but also other bioactive substances that could work synergistically.
2. Better bioavailability: The vitamins in foods could often be better absorbed and utilized by the body than isolated vitamins in supplements.
3. Lower risk of overdose: With a diet of natural foods, the risk of toxic overdose of fat-soluble vitamins (A, D, E) is practically excluded.
Situations in which dietary supplements could be meaningful:
1. Proven deficiency states: With a diagnosed vitamin deficiency, targeted supplementation under medical supervision could be necessary.
2. Increased need in certain life phases: During pregnancy, breastfeeding, or intense physical exertion, the vitamin requirement could be increased.
3. Limited dietary options: With certain diets (e.g., strictly vegan diet in the case of vitamin B12) or food intolerances, supplements could be a meaningful addition.
4. Seasonal support: Especially in the winter months, when the body's own vitamin D production is limited, a supplementary intake could be considered.
