Sunlight isn’t always enough, Fultium D3 helps to fill the gap. Children from the age of 1 year and adults need 10 micrograms (mcg) of vitamin D a day. This includes pregnant and breastfeeding women, and people at risk of vitamin D deficiency. During the autumn and winter, you need to get vitamin D from your diet because the sun is not strong enough for the body to make vitamin D. But since it's difficult for people to get enough vitamin D from food alone, everyone (including pregnant and breastfeeding women) should consider taking a daily supplement containing 10 micrograms of vitamin D during the autumn and winter. Some people will not make enough vitamin D from sunlight because they have very little or no sunshine exposure. The Department of Health and Social Care recommends that adults and children over 4 take a daily supplement containing 10 micrograms of vitamin D throughout the year if they: are not often outdoors – for example, if they're frail or housebound are in an institution like a care home usually wear clothes that cover up most of their skin when outdoors If you have dark skin – for example you have an African, African-Caribbean or south Asian background – you may also not make enough vitamin D from sunlight. You should consider taking a daily supplement containing 10 micrograms of vitamin D throughout the year.
