These active ingredients boost your immune system

When the days become shorter, colder and darker, immune boosters are needed. Especially in times of corona. Read the current health tips from the Victoria Pharmacy Zurich on how you can strengthen your immune system with simple means.

One vitamin that is often recommended to strengthen the immune system is vitamin D3. But wait: Vitamin D3 is actually not a vitamin at all. Because vitamin D is also produced by the body itself in combination with sunlight, which is why it is actually a hormone.

Triple effect: Vitamin D3 

Since in the winter months the sunlight in Switzerland is too weak for sufficient production of vitamin D3, it should be taken as a dietary supplement. Two further advantages of vitamin D3: The hormone not only supports the absorption of calcium, but also contributes to a strong immune system.

Ginger, the supertalent

Even our grandparents knew the home remedy hot lemon with ginger. Now it has also been scientifically proven that the spicy ginger root and the acidic lemon already in the saliva in the mouth have a strengthening effect on the immune system. Ginger, which was named medicinal plant of the year in 2018, also has antioxidant, antibacterial, muscle-relaxing effects and promotes blood circulation and digestion.

Good for the intestine - good for me

At the latest after the book "Intestine with Charm" we know how important intestine health is. Since the immune system is largely located in the intestine, probiotics, which build up the intestinal flora, also have a positive effect on the immune system. Vitamins B6 and B12 also act in the intestine and are therefore immune boosters.

Vitamin C

Vitamin C supports the body's immune system by promoting the formation of antibodies, among other things. The direct fight against bacteria in the body is carried out by white blood cells, which consume a large amount of the vitamin in the process. In addition, it acts as an antioxidant and eliminates free radicals in the body, which serves to protect blood vessels and organs.


A sufficient supply of zinc stabilizes the immune system. In addition to its antiviral effect, the trace element also strengthens the structure of the mucous membranes, which makes it more difficult for viruses to penetrate the body


Preparations with Echinacea are said to have immunostimulating and immunomodulating properties. Echinacea is said to reduce susceptibility to colds, promote the healing process and reduce the duration of illness.

Lots of movement – lots of sleep

It is also recommended to get plenty of exercise - at least 20 minutes a day. Sufficient sleep and a balanced diet also help to strengthen the body.
