Colds and prevention

Did you know...

Today we talk about colds and prevention.


With the arrival of winter and falling temperatures, it is common to catch one of the cold viruses (it is estimated that there are more than 200 related viral strains).

The symptoms associated with a cold are, in particular, a runny nose, joint and bone pain, headache and chills.

These symptoms usually last from two days to a week, unless complications arise, such as bronchitis, in which case an antibiotic prescribed by a doctor is needed.

There are some precautions that can help prevent infection and strengthen the immune system.

First of all, you need to look after your gut: that is where 75% of our immune defences are produced; taking probiotics supports the well-being of the gut bacterial flora, which is essential as a first line of defence against oxidative stress and infections.

Getting vitamins and minerals from your diet is essential for strengthening your immune defences, so it is important to eat plenty of fruit and vegetables and, if that is not enough, to turn to specific supplements containing high concentrations of them.

Some vitamins are particularly recommended:

  • vitamin C: several studies have shown that vitamin C is genuinely effective in preventing colds and flu (a 50% lower likelihood), provided it is taken regularly as a deterrent. One gram a day is more than enough. Taking vitamin C once you are already ill, however, has no effect.
  • B vitamins: a group of vitamins (B1, B2, B3, vitamin PP, B5, B6, B8, B9, B12, vitamin H) which together help reduce the effects of stress, tiredness and nervousness, contributing to the normal functioning of the nervous system.
  • vitamin E: a powerful antioxidant that protects cell membranes from attack by free radicals, molecules that weaken the immune system. Vitamin E also has a vasodilating function. Read this post too for more information.
  • coenzyme Q10, vitamins A and C, lipoic acid and trace elements (selenium, manganese, copper and zinc): these substances also neutralise free radicals effectively.
  • vitamin D: helps to maintain normal bones.
