5 'essential' vitamins to boost health over winter – 'destroys virus-infected cells'


Vitamin B12

Research has shown that vitamin B12 can bear a significant impact on increased energy levels and mood boosts.

Ms Snover said: “This is because it plays a vital role in serotonin production, otherwise known as the happy hormone. If you’re someone who struggles with lethargy in the winter months – the dark evenings and cold weather do us no favours – this should be a staple in your vitamin routine.”

Vitamin B12 occurs naturally in some meat, fish and dairy products like cheese and milk.

However, Ms Snover continued: “A lot of us cannot absorb it properly. And vegans, because they are not consuming those products, are more susceptible to being deficient.

“For this reason, supplementation is a great idea as it can bypass that and ensure you are digesting appropriate levels to make an impact.”

Vitamin A

Another vitamin essential to beating winter colds is Vitamin A, which helps boost the production and growth of immune cells.

Public health nutritionist, Doctor Emma Derbyshire from the Health and Food Supplements Information Service (HSIS) told Express.co.uk: “Low intakes can increase the risk of pathogens invading the eye and the respiratory tract.

“One in ten toddlers and primary schoolchildren don’t get the recommended amount of vitamin A. All children under five should be given a supplement containing vitamins A, C and D, according to the Government.”

Otherwise, vitamin A can be found in a number of foods, such as carrots, leafy green vegetables, fish oils, and dairy products, to name a few.


With immunity in mind, zinc is another cornerstone vitamin, according to Ms Snover, for anyone looking to help shield themselves from winter bugs.
