After a couple of years of mask-wearing, social distancing and hand sanitising, the common cold is back. And – according to some people – back with a vengeance. Some are calling it a “super cold” – others, “the worst cold ever”. Fortunately, there may be a way to reduce the duration of a cold: vitamin D supplements.
People take vitamin supplements for all kinds of reasons, from maintaining general health to preventing cancer. But there’s no convincing evidence that vitamin supplementation benefits people who don’t actually have a vitamin deficiency.
