The best vitamins for colds

Which are the best vitamins for colds?

Seasonal changes, cold weather and daily stress can weaken our natural defences, making us more vulnerable to colds and flu. That is why strengthening the immune system through proper nutrition and targeted supplements is essential for staying healthy. In this article, we explain which vitamins are best for preventing and fighting colds, and which products can help you avoid them.

Which vitamins are good for preventing colds?

  • Vitamin C

This vitamin is perhaps the best known for its role in preventing colds. Vitamin C boosts the production of white blood cells, which are essential for fighting infections. It is also a powerful antioxidant that can reduce how long symptoms last if you do become unwell. Natural sources such as citrus fruits, kiwi and strawberries are ideal, but you can also find it in specialised supplements.

  • Vitamin D

Known as the "sunshine vitamin", vitamin D is crucial for a strong immune system. A deficiency can increase susceptibility to respiratory infections. If you spend little time in the sun, vitamin D supplements are an excellent option.

  • B vitamins
  1. Vitamin B6: Helps maintain hormonal balance and improves immune function.
  2. Vitamin B12: It is key to the production of red blood cells and strengthening the nervous system.
  3. Vitamin B3 (niacin): Contributes to DNA repair and improves the immune response.
  • Vitamin K2

Although better known for its role in bone health, vitamin K2 also has properties that support the immune system by improving the body's overall health.

  • Zinc and selenium

These minerals, although not vitamins, are essential for strengthening your natural defences and preventing recurring infections.

How can I strengthen my defences against flu?

As well as including these vitamins in your diet, there are specific products designed to support your immune system, as sometimes our diet does not provide the amounts we need:

  • Inmunoferon: Its formula based on AM3 (glucomannan and soya protein) naturally stimulates the body's defences. It is ideal for people with weakened immune systems or those who suffer from frequent colds.
  • Aboca Natura Mix Refuerzo: This product combines natural ingredients such as echinacea extracts, acerola and other antioxidants that enhance the immune response. It is perfect for preventing and treating the first symptoms of a cold.
  • Bion3 Defense: This supplement combines essential vitamins, minerals such as zinc and selenium, and probiotics that improve gut health, which is key to a strong immune system.
