The NHS has issued a UK-wide alert urging millions of people to take a daily vitamin D supplement costing as little as 2p per pill. The advice comes as the UK faces several more weeks of early sunsets and limited daylight, which is essential for the body to produce vitamin D naturally.
From October to March, sunlight is not strong enough for the body to make sufficient vitamin D, so the NHS recommends a daily 10 microgram (400 IU) supplement to maintain healthy bones and muscles. The alert was shared on the NHS X account, emphasising that vitamin D can be purchased from most pharmacies and retailers.
Vitamin D is crucial for calcium absorption, bone health, and immune system support. While the body can produce it from direct sunlight on skin during summer months, autumn and winter require dietary sources or supplements. Foods rich in vitamin D include fatty fish, egg yolks, and fortified products, but supplements are often the most reliable source.
The government, NHS, and Public Health England advise everyone to consider a daily supplement during autumn and winter. Certain groups, such as people with dark skin or those who rarely go outdoors, should take it year-round. Boots offers a pack of 180 tablets for £4, working out to 2p per pill.
Excessive intake (over 100 micrograms daily) can lead to hypercalcaemia, causing nausea, weakness, and kidney damage. People with kidney problems, sarcoidosis, or primary hyperparathyroidism should consult a GP before taking supplements. Vitamin D may also interact with certain medications, including cholesterol-lowering drugs and steroids.
