Buy vitamins to boost immune system defences

Table of contents

Some of the factors that can affect our defences, weakening them and causing colds include exposure to cold, sudden changes in temperature, a diet low in fruit and vegetables, and stress at work.

One of the foundations for a healthy immune system is a balanced diet, in which basic nutrients and vitamins should have a special place. At HSNstore.eu we give you an extra boost with a wide range of products designed to enhance your immune system's defences*.

*Vitamin A contributes to the normal function of the immune system.

How can supplements help to boost the immune system?

Supplements to strengthen the immune system are made from vitamins, minerals, and ingredients of natural origin with immunostimulant action. In other words, they support the body's immune system, such as vitamin B12.

What compounds help us to maintain our defence system?

Among the compounds present in natural supplements to maintain the defence system, we can highlight:

  • Vitamins contribute to the protection of cells from oxidative stress (C and E) and support the proper function of the immune system (C, B6, B12 and D). You can find them all together in the multivitamin Seasonal Change Vitamins.
  • Minerals such as zinc and selenium also contribute to the normal function of the immune system and protect against oxidative stress.
  • Bee pollen contains protein and fibre, both of which help prevent nutritional deficiencies.
