For some time, the Department of Health and Social care have recommended that vitamin D supplementation should be considered for all adults between October and March. However, this year, due to the Covid-19 pandemic reducing the amount of time spent out and about, they have upgraded that advice from ‘consider taking’ to ‘being important to take’. Lack of vitamin D has been linked to many health complaints, including dry eyes, glaucoma, macular degeneration and cataracts. So, for your eye health as well as your general health it is important to ensure you have enough Vitamin D. From the NHS website:
“It's important to take vitamin D as you may have been indoors more than usual this year.
Adults should take 10 micrograms (400 IU) of vitamin D a day between October and early March to keep your bones and muscles healthy. Breastfed babies from birth to 1 year of age should be given a daily supplement containing 8.5 to 10 micrograms of vitamin D to make sure they get enough. Formula-fed babies should not be given a vitamin D supplement until they're having less than 500ml (about a pint) of infant formula a day, as infant formula is fortified with vitamin D. Children aged 1 to 4 years old should be given a daily supplement containing 10 micrograms of vitamin D.”
Between late March/early April to the end of September, most people can get all the vitamin D they need through sunlight on their skin and from a balanced diet. However this was less likely to have been the case in 2020 and if the pandemic continues into 2021 you should check the NHS advice next March to see if it is recommended to continue taking Vitamin D supplementation through the spring next year.
There have been some reports about vitamin D reducing the risk of coronavirus (COVID-19). But there is currently not enough evidence to support taking vitamin D to prevent or treat coronavirus.
