All pregnant and breastfeeding women Infants and children under 5 years old People who have low or no exposure to the sun, for example those who cover their skin for cultural reasons, are housebound, confined indoors for long periods or live in an institution such as a care home People from minority ethnic groups with dark skin such as those of African, African-Caribbean and South Asian origin, who require more sun exposure to make as much vitamin D Guidance from Scottish Government 10–15 minutes of unprotected Scottish sun exposure is safe for all. Once sunscreen is correctly applied, vitamin D synthesis is blocked. Staying in the sun for prolonged periods without the protection of sunscreen increases the risk of skin cancer. Too much vitamin D may be harmful Daily supplements at the recommended amounts will be enough Avoid daily high dose vitamin D supplements More than 100 micrograms for adults and children from age 11 More than 50 micrograms for children age 1-10 years More than 25 micrograms for infants under 12 months.
