I read years ago that vitamin, “I think C” would prevent scurvy. If so there is no question that vitamins have a potential benefit.
I think if you eat a healthy diet then they are not necessary but some of us do not eat a healthy diet.
I remember in Churchill’s six volume “History of WWII”, he was trying to figure out ways to supply Malta. He suggested that maybe they could parachute vitamins to them. A docter explained to him that you need a lot more than vitamins. At least Churchill was thinking.
If people eat their veggies and their greens and have a healthy diet then there’s no need for vitamin supplementals. But who does that? Really?

The man who discovered vitamin C found that the vitamin alone will not cure scurvy, one has to consume the whole flesh of the fruit to cure scurvy.
