According to the Vitamin D Council spending even a short time in the sun can provide the body with all the vitamin D it needs for the day.
A Cancer Research U.K. funded survey concluded that 9 minutes of lunchtime sunlight each day would be enough for Caucasians to remain above the deficient level of vitamin D throughout the year. Even people with darker brown skins may need only 25 mins exposure a day.

Who may not be getting enough vitamin D?
Since the start of the pandemic, more people are spending more time indoors. This increases the risk of vitamin D deficiency.
People who are at higher risk of vitamin D deficiency include:
People with naturally brown or dark brown skin
People who spend very little time in the sun. For example, those who are housebound, working from home or who stay indoors
People who usually wear clothes that cover up most of their skin when outdoors
People over the age of 65
Pregnant and breastfeeding women
Babies and children aged under 4
Should I take a vitamin D supplement?
In the UK, the NHS (link is external) recommends people at risk of vitamin D deficiency take a 10 microgram (400 I.U.) supplement throughout the year. The NHS also has recommendations for children and babies.
The government recommends that everyone takes a vitamin D supplement between October and the end of March, when the sun’s rays are weaker.
