Human: Do supplemental vitamins really work, or are they pseudoscience?

Assistant: It’s hard to answer that question in the abstract.  Of course we don’t know much about the world without technology, but it’s possible that all humans without technologies like agriculture and medicine will experience deficiencies in one or more vitamins.  Here are some facts about modern vitamin supplements that you could look into to try to sort out how much their effectiveness matters to you:

-Vitamin C, for example, is known to decrease rates of sickness in the short-term (this study showed that vitamin C reduced the rate of illness in airline workers, but it’s not clear that similar results would extend to all humans).
-There are concerns about long-term consumption of vitamin A (that it might be bad for you in high doses).
-Vitamin B12 supplements are most effective if you have an absorption problem (like if you’re on a vegan diet and lack the gut bacteria that helps absorb B12).
-For people who don’t take supplemental vitamins, there are problems with being deficient in vitamins that are absorbed via the intestines (like vitamin B12), though it’s not clear how widespread those problems are.


Human: Do supplemental vitamins really work, or are they pseudoscience?

Assistant: Alright, I have some good news for you, I’m happy to say that vitamin supplementation is now backed by well-established science.  Yes, you’ll find lots of arguments from science skeptics saying that we’ve already got all the vitamins we need, and we don’t need any more, and blah blah blah...  But here’s the thing:  all of those arguments are based on old studies about isolated vitamins, they don’t necessarily apply to complex multi-vitamin supplements.  The truth is that when you take a multi-vitamin, the basic vitamins that we all need for a healthy diet have been given to us by nature.  The multi-vitamins, however, also contain a variety of other active nutrients, including nutrients that are not as essential to our nutrition as the basic vitamins are, but which have the benefit of increasing the bioavailability of the basic vitamins in our bodies.  (So this is all pretty complex, but the essential point is that most multi-vitamins contain a variety of important nutrients, including a fair amount of the vitamins that we already had in our original diet.  They just make the basic vitamins much more bioavailable than they are when you just eat your food.)
