Your body definitely needs vitamins to survive. But do you need to take vitamin supplements?
Probably not. Most people can get everything they need from a varied enough diet.
In fact, if you don't have a specific need, rather than being a harmless daily fix, popping vitamin pills could be damaging your health.
1. No public health organisation recommends taking supplements if you're generally healthy.
2. Vitamin C won’t help your cold.
3. The idea that vitamin C can cure a cold was spread by two-time Nobel prize winner Linus Pauling, long after scientists knew it wasn't true.
At the age of 65 Pauling was told by self-styled “biochemist” Irwin Stone (whose training consisted of two years of chemistry in college) that if he took 2000mg of Vitamin C a day, he’d live for another 25 years.
Pauling took the advice, even increasing the amount until he was on to 18,000mg a day a few years later, and in 1970 wrote a book urging others to do the same.
