evidence for vitamin d3
Our honest take
A high-strength vitamin D oral spray giving 4,000 IU (100 µg) a day. That is the most the NHS says adults should take daily without medical advice, and ten times the 10 µg most people need in autumn and winter. It makes sense if a health professional has recommended a high dose; for everyday use the 1,000 IU version is the better choice.
- You have been advised by a health professional to take a high daily dose of vitamin D
- You find tablets hard to swallow
- You just want to follow the NHS winter advice: a 400 to 1,000 IU product is enough
- You take any other vitamin D product: this alone reaches the 100 µg daily limit
- You are pregnant, breastfeeding, have kidney disease or high calcium levels: ask your GP first
The science
Vitamin D3· evidence: Strong
Vitamin D3 (cholecalciferol) is the form the skin makes from sunlight. In the UK there is not enough strong sunlight from about October to March, so many people have low levels over winter. Good-quality trials show supplements reliably raise blood levels and correct deficiency, and that matters for bone health in people who are low.
The NHS advises everyone to consider 10 µg (400 IU) a day in autumn and winter, and all year round for people who get little sun, cover their skin, have darker skin or live in care homes. For people who already have adequate levels, large trials have not shown that extra vitamin D prevents falls, fractures or other illness.
In short: a modest daily dose is sensible and cheap insurance for most UK adults in winter. Very high doses are not better and should only be taken on medical advice.
Vitamin D contributes to the normal function of the immune system. Vitamin D contributes to the maintenance of normal bones. Vitamin D contributes to the maintenance of normal muscle function. Vitamin D contributes to the maintenance of normal teeth. Vitamin D contributes to normal absorption/utilisation of calcium and phosphorus. (Applies where a daily dose gives at least 15% of the NRV, i.e. 0.75 µg.)
Typical dose: 10 µg (400 IU) a day is the NHS advice for adults and children over 1. Doses of 25 µg (1,000 IU) to 50 µg (2,000 IU) are common and safe for adults. Babies under 1 need 8.5 to 10 µg a day unless they have more than 500 ml of formula.
Safety: Do not take more than 100 µg (4,000 IU) a day without medical advice (FSA/NHS); children aged 1 to 10 should not have more than 50 µg, and babies under 1 no more than 25 µg. Long-term very high intake can raise blood calcium, which can damage the kidneys and heart. People with kidney disease, sarcoidosis or high calcium levels should speak to their GP first.
