Sure. But the vast majority of people are not deficient. 86% of Americans take vitamins or supplements of some sort. 21% have been diagnosed with kind of vitamin deficiency. And the vast majority of those could, to your point, eat more lettuce. [1]
"Most people have no need to take vitamins and are wasting their money on supplements that are unlikely to improve their health and may actually harm it." [1]
If you aren't deficient, you may end up with an excess of fat soluble vitamins (A, D) which may actually poison you.
