Understanding symptoms during your COVID-19 recovery

Information on how your symptoms might affect your food and drink intake

On this page you will find some information to help you understand how your symptoms are linked to nutrition.

Choose a part of the body or health aspect to find information on:

  • symptoms
  • how the symptoms are linked to diet and nutrition
  • relevant links for more information and useful tips.

The advice given here will help you improve your symptoms to minimise the impact on your nutrient intake. It is not possible to give highly specific advice since a change in one aspect of your diet will change your diet overall. This means that you need personalised advice from a dietitian or registered nutritionist.

It is important to remember that some symptoms caused by the COVID-19 virus can be improved by changing your diet. Changing your diet cannot cure them.

There are also useful resources related to:

  • supplements
  • monitoring
  • post-critical care recovery, mental health and myalgic encephalomyelitis (ME) and chronic fatigue syndrome (CFS).

Useful resources


To date, it is unknown if over the counter vitamins and supplements in general are helpful, harmful, or have no effect in treatment of ongoing symptoms of COVID-19.

Vitamin D plays a role in preventing COVID-19. For long term consequences of COVID-19 this can be helpful particularly when living in an environment with lack of sun or during UK winter (10 micrograms or 400 International units) per day between October and March. More than this can weaken bones and harm kidneys. Obtaining advice from healthcare professionals is vital.

You can watch our Q&A session with topic experts where they discuss the use of supplements.

Keeping a diary

It can help to keep a diary of your symptoms. This will help you to learn what works best to manage your symptoms. It can also help health care professional understand the pattern of your symptoms. There are many ways to keep a diary by using an app or keeping a paper copy.
