Over the winter period, our immune systems need a boost. With the onset of winter, the cold weather makes our immune responses more sluggish. That’s why it’s so important to take care of our bodies’ natural defences: so they can keep on playing their vital role.
Wat is immunity ?

Immunity refers to the human body’s ability to defend itself against harmful micro-organisms (bacteria, parasites, viruses) to remain healthy.
- Regular physical activity
- Good quality sleep
- A healthy and balanced diet
These are the three basic recommendations for maintaining a strong immune system.
Taking food supplements can also help you achieve this.
What are the natural solutions for boosting your immune system ?
Vitamin C.
Vitamin C for your body’s natural defences1.
Vitamin C, also known as ascorbic acid, is a water-soluble vitamin which is naturally present in the human body. It plays a number of different roles:
- It is an integral part of the immune system.
- It contributes to protecting cells from oxidative stress.
- It plays a part in energy metabolism, helping to reduce tiredness.
- It is involved in iron metabolism - helping the body to absorb iron.
It is vital to provide for daily Vitamin C needs because this nutrient is involved in a whole range of physiological processes. How can you do this? By drawing vitamin C from key foods (citrus fruits, red berries, kiwis, peppers, fennel, parsley, potatoes, etc.). The recommended daily amount is around 80 mg/day for adults.
Anyone not regularly eating foods which contain vitamin C should take a vitamin C dietary supplement to ensure they are getting their recommended daily intake.

La vitamine D.
Vitamin D to regulate your immune function2.
Vitamin D, D3, or≪ cholecalciferol ≫ to scientists is a fat-soluble vitamin which performs a range of functions.
Also known as the “sunshine” vitamin, it contributes to maintaining a healthy immune system. But it also does more!
- It contributes to maintaining good bone health.
- It contributes to maintaining proper muscle function.
If one of your priorities is to ensure you meet your daily vitamin D nutritional requirements, it is important to include certain foods in your diet such a cod liver oil, salmon, herring or dark chocolate. These foods mainly include fatty fish and oils.
Furthermore, a vitamin D supplement may be useful in the event of a deficiency, in particular at times of year when there are fewer hours of sunlight, such as autumn and winter.
