There has been a lot of noise in the media recently about vitamin D, COVID19 and immunity.

You may be are aware that vitamin D is produced in the skin after exposure to sunlight and that it promotes calcium absorption from food to keep bones strong and free from osteoporosis.
But were you aware of its role in ensuring a healthy immune response?

Research shows that vitamin D plays a role in priming infection fighting ‘T’ cells and regulating the production of inflammatory proteins called ‘cytokines’.

Everyone should take 10 micrograms of vitamin D per day

Whilst there is still insufficient evidence to conclusively prove that vitamin D beneficially affects COVID19 outcomes, there is plenty of evidence to support the importance of adequate vitamin D intake for immune support and the maintenance of bone and muscle health.

In fact, the governments updated advice around vitamin D during the pandemic is that everyone should consider supplementing with 10 micrograms of vitamin D per day.

So how can you ensure you are getting enough vitamin D?

Many of us struggle to get enough vitamin D from sunlight exposure and diet alone.  Less time spent outside, SPF and limited food sources of vitamin D make it difficult to maintain optimal circulating levels.

Good Dietary Sources of vitamin D

  • Oily fish like salmon, herring, tuna and mackerel
  • Liver
  • Egg yolks

As an alternative to a vitamin D supplement, consider taking cod liver oil.  You only need 1 tsp per day (or 2 capsules if you prefer), and this should provide your daily recommended dose of 10 micrograms.  It’s a great source of vitamin A too.  Don’t take more than the recommended daily dose, and don’t take fish liver oils if you are pregnant.

The future of optimum health lies with a better understanding of the interaction between your genes and your diet. Talk to the DNA Nutritionist to arrange your test and achieve the best version of yourself.
