Public Health England advised the government on Thursday that people should consider taking a daily supplement of vitamin D in autumn and winter since it may be difficult to meet the average daily intake of 10 micrograms.
This advice is based on the recommendations of the Scientific Advisory Committee on Nutrition (SACN) following its review of the evidence on vitamin D and health.
Vitamin D is made in the skin by the action of sunlight and this is the main source of vitamin D for most people. SACN could not say how much vitamin D is made in the skin through exposure to sunlight, so it is therefore recommending a daily dietary intake of 10 micrograms.
PHE advises that in spring and summer, the majority of the population get enough vitamin D through sunlight on the skin and a healthy, balanced diet. During autumn and winter, everyone will need to rely on dietary sources of vitamin D. Since it is difficult for people to meet the 10 microgram recommendation from consuming foods naturally containing or fortified with vitamin D, people should consider taking a daily supplement containing 10 micrograms of vitamin D in autumn and winter.
People whose skin has little or no exposure to the sun, like those in institutions such as care homes, or who always cover their skin when outside, risk vitamin D deficiency and need to take a supplement throughout the year. Ethnic minority groups with dark skin, from African, Afro-Caribbean and South Asian backgrounds, may not get enough vitamin D from sunlight in the summer and therefore should consider taking a supplement all year round.
Children aged 1 to 4 years should have a daily 10 microgram vitamin D supplement. PHE recommends that babies are exclusively breastfed until around 6 months of age. As a precaution, all babies under 1 year should have a daily 8.5 to 10 microgram vitamin D supplement to ensure they get enough. Children who have more than 500ml of infant formula a day do not need any additional vitamin D as formula is already fortified.
Dr Louis Levy, Head of Nutrition Science at PHE, said:
A healthy, balanced diet and short bursts of sunshine will mean most people get all the vitamin D they need in spring and summer. However, everyone will need to consider taking a supplement in the autumn and winter if you don’t eat enough foods that naturally contain vitamin D or are fortified with it. And those who don’t get out in the sun or always cover their skin when they do, should take a vitamin D supplement throughout the year.
Vitamin D supplements are available free-of-charge for low-income families on the Healthy Start scheme.
Vitamin D regulates the amount of calcium and phosphate in the body, both needed for healthy bones, teeth and muscles. It is found naturally in a small number of foods including oily fish, red meat, liver and egg yolks and in fortified food like breakfast cereals and fat spreads.
Ms Geeta Sidhu Robb, a raw chef, nutritionist, holistic health and food technician and the founder of award winning Nosh Detox said:
“This is huge news, we at Nosh Detox have been talking about this for five years. Most people do not notice they are lacking and losing vitamin D until it’s too late. It takes 6 days of exposure to the sun to make up for 26 days of no, or very little exposure.
Vitamin D is in fact a hormone, which has a profound effect on how we feel and our moods. It is worth noting that people with darker skin pigmentation find it harder to absorb Vitamin D from the sun, as pigment slows down the absorption rate.”
