Our honest take
One small tablet gives 50 µg (2,000 IU) of vitamin D3, 1,000% of the daily reference intake, and the pot lasts four months, so it is cheap per day. The NHS advises everyone to consider 10 µg a day in autumn and winter, so this is five times that: fine for most adults, as it is half the 100 µg upper limit, but do not combine it with another vitamin D product or high-strength multivitamin without advice. A simple, no-frills option.
- You want a higher-strength daily vitamin D3 at a low cost
- You get little sun, cover your skin outdoors or have darker skin
- You only want the NHS-recommended 10 µg a day: a lower-strength product is enough
- You already take a multivitamin or D3 + K2 with vitamin D
- You have high calcium levels, kidney stones or sarcoidosis, without speaking to your GP
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.
