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.
Boost your defences with vitamin C
Vitamin C 500mg by EssentialSeries is a food supplement in vegetable capsules made from L-ascorbic acid as a vitamin C form, and 12:1 Citrus aurantium extract standardised to 60% bioflavonoids.
The properties of vitamin C contribute to normal energy metabolism, and proper function of the immune system and protect cells from free radicals.
It's suitable for vegetarians and vegans!
Support your immune system with probiotics*
*The vitamin D in HSN Biotics formulas contributes to the normal function of the immune system.
Immu Biotics (Ferments) 25B CFU by EssentialSeries is a product formulated from a combination of 6 strains of Lactobacillus ferments and 3 strains of Bifidobacterium, with fibres such as Inulin and Fructooligosaccharides in its composition.
It is rich in vitamin D3, which also contributes to the normal function of the immune system.
The bacteria that have been used in Immu Biotics (Ferments) 25B CFU come from cultures extracted from human samples, making this condition fulfilled and the quality of the product superior.
Protect your immune system with zinc bisglycinate
It is a supplement in vegetable capsules made from the zinc salt of glycine, i.e., chelated zinc. The minerals in Zinc Bisglycinate help to maintain the function of the immune system.
