With flu season well and truly upon us again, a pharmacist has explained an important piece of NHS guidance for managing your immune system. At present, the number of people in hospital with flu in England is at a record level for this time of year, as health officials warned the NHS is bracing itself for an "unprecedent wave" of infections.
With that in mind, it's in our best interests that we do everything we can to avoid being admitted ourselves. While cold and flu remedies are normally top of sufferers' priorities, according to pharmacist, Riya, we need to keep on top of our vitamins too - and there's one in particular you should consider.
"Before you rush out and buy your multivitamins, here is what the NHS actually recommends," she began in a TikTok video. Riya continued: "The only supplement recommended for the general population by the NHS is actually Vitamin D - not multivitamins, not Vitamin C, not zinc - just Vitamin D."
According to the pharmacist, the vitamin benefits us more in the autumn and winter months as we don't receive enough of it naturally due to reduced sunlight hours.
"Whilst Vitamin C is essential for your immune cell function, it doesn't actually prevent you from getting colds and flu and doesn't make the symptoms any milder," Riya elaborated.
She acknowledged, however, that Vitamin C may reduce the length of colds and flu by "half a day", while there "isn't strong enough evidence" for the NHS to recommend zinc as a "routine supplementation".
Riya continued: "So the only recommendation is Vitamin D. The NHS suggests 10 micrograms or 400 units of Vitamin D between October and March. Studies have found that adequate Vitamin D does reduce your risk of respiratory infections, especially in those who are deficient."
An average of 1,717 flu patients were in beds in England each day last week, including 69 in critical care, according to the first of this year’s NHS winter situation reports.
This is 56 per cent higher than the equivalent numbers for the same week in 2024, when the total was 1,098 with 39 in critical care. It is also well above levels seen at this point in both 2023 (243 patients) and 2022 (772).
The NHS has also reported that 30 per cent of patients arriving by ambulance at hospitals in England last week waited at least 30 minutes to be handed over to A&E teams.
Meanwhile, the UK Health Security Agency said respiratory syncytial virus (RSV) cases have also increased week on week. Hospitalisations rose from 2.38 to 3.75 per 100,000 people, while positive tests increased from 8.7 per cent to 10 per cent.
Positive Covid tests, however, fell from 2.3 per cent to 2.1 per cent, while hospitalisations with Covid increased slightly from 0.88 to 1.03 per 100,000 of the population.
