Why do people take specific vitamin supplements when their multi-vitamin already covers 100 pct of the daily requirement of that vitamin?

Update:

A pharmacist told me that anything above and beyond the minimum daily requirement of a vitamin gets flushed down the toilet since the body doesn't store up the extra. He had no reason to lie. Yet people will take a multi-vitamin pill that contains 100% of things like B-12, iron, and C, plus an additional B-12, iron, or C pill on top of that for some reason.

    Everything you need could not possibly fit in a 500 mg vitamin. Or even several supplements. Potassium RDI alone is 4,700 mg. Plus there's calcium, magnesium, essential fatty acids, choline, antioxidants, flavanoids, etc., etc. Plus many known and unknown nutrients that they don't bother putting in the multi-vitamin at all because it's a lot of trouble. That's why it's better to always get everything you need from food, to get all that "misc" stuff which is actually more like the majority. But barring that some other supplements can help such as fish oil, choline/lecithin and 2,000 i.u. vitamin D. Since most multis don't have the ideal amount of vitamin D and low blood vitamin D is very common. Or you could just eat fish, egg yolks and/or get a little bit of a tan for something better, but not everyone does.

    Some supplements do contain 3,000% of this or that which is in fact a waste. That part is true. And such a supplement still doesn't contain the many other things you need. Even nutrients related to the one thing it does contain are typically missing.

    Your pharmacist has no reason to lie but he does have reason to repeat what he's been told. They aren't educated on nutrition, that's what a nutritionist is for. So they get told the basics of just take 1 multivitamin and more than 1 is pointless. And since they're told to watch out for snake oil they get overly skeptical of anything they don't know about. Plus there's a lot of misinformation floating around on basic critical nutrients your body is *made of*, such as essential fatty acids. Particularly as materials for the heart and brain. So not being a nutritionist they might get skeptical of those. Even as the government dietary guidelines are pushing for more fish, *especially* in pregnant women to prevent birth defects (often heart development issues) from the lack of this raw material. They're trying to get the FDA to update their poorly worded warning too.

    So long story short get your needs from learning about food sources, and multi-vitamins aren't even close to complete. But adding other supplements with *missing* nutrients (not the same nutrients), while still not even close to complete, is the next best thing.

    A multi vitamin DOES NOT contain 100% of anything. It is usually less and in some cases like vitamin C can be way over like 500% or more.

    So you have to take supplements of individual that you do not get or get enough of in a vitamin.

    And for some health reasons like iron or calcium or vitamin D. Are more common ones as well as C and B complex.

    So what ever u were thinking is wrong. A multi is a good start and you add from that according to certain needs.

    biotin 10%

    Deficiencies, medical issues, etc. Multivitamins rarely give women enough iron, or give men enough zinc. Looking at my multivitamin right now it doesn't give me nearly enough iodine. I'm sure there are other things that it doesn't cover 100%.
