Cold season is just around the corner. You can strengthen your immune system to enjoy holidays without getting a cold or flu. But how? Find out which vitamins are vital for the immune system in the article!

Vitamin C - Classic for Your Immune System

Hot lemon, sea buckthorn, and elderberry juice are tried-and-true tips when a cold is coming. They all contain Vitamin C and strengthen the immune system.

Vitamin B – Complex for a Good Defense

The Vitamin B complex contains eight different water-soluble vitamins that contribute to the normal functioning of the immune system. They help recognize bacteria and viruses, contribute to cell growth, and keep the mucous membranes intact. It is essential, for example, in the mechanical defense against pathogens, even if you already have a runny nose. However, Vitamins B also acts as antioxidants. They protect against oxidative stress, which is harmful to the immune system.

Vitamin D – the Sunshine Vitamin

Vitamin D can be formed in the skin while exposed to sunlight in the summer months. However, it also can be found in foods in smaller amounts. Foods that contain the most Vitamin D are fish, cheese, eggs, and mushrooms.

Vitamin D activates specific immune cells (T-cells) when they contact a pathogen. It is also involved in immune system regulation. It is essential to prevent the immune response from overshooting and balance it.

Vitamin A – the All-Rounder

The fat-soluble Vitamin A and its equivalents (e.g., Beta-Carotene) fulfill various functions in the body. There is a simple reason why this vitamin is essential for the immune system: Vitamin A ensures intact mucous membranes, which form a barrier for pathogens. This way, pathogenic viruses and bacteria don't even get into your body, and you don't get sick.

Minerals to Strengthen the Immune System

Additionally to vitamins, you can try some minerals to strengthen the immune system. Just like vitamins, these can be found in a healthy diet.


Zinc has a very similar effect to Vitamin C for the immune system. On the one hand, it serves as an antioxidant and thus reduces oxidative stress. On the other hand, it is involved in forming white blood cells.

Ensure an optimal supply of Zinc with ZINC from CLAV. The contained Zinc Chelate Complex is remarkably well-tolerated and has a high bioavailability.


Copper also has an antioxidant effect. It stabilizes the cell membrane and thus extends the survival time of immune cells.


A Selenium deficiency weakens the immune system. Because it has a crucial part in immune cells formation. In addition, Selenium has an antioxidant effect and thus additionally strengthens the immune system.
