Some people assume for whatever reason that vegetarians need to take a multitude of vitamins. I guess they think we don’t get enough from the vast array of fresh fruits and vegetables compared to their menu of three or four animals.
The first people I knew of who took vitamins daily were not vegetarian. In fact, I’d be willing to bet that the majority who do aren’t. The vitamin and supplement industries were built to take advantage of everyone’s insecurities, not just the veg*ns.
The only supplement I use regularly is B12. I have 2000 mcg weekly and that’s it. I do have a bottle of multi-vitamins but I really don’t recall when it was I had one last. B12 is important for both veg*ns and omnivores. A deficiency there (which takes years to develop) can lead to problems with your nervous system - and that’s serious.
If you want vitamins and minerals, get them from fresh, whole, ripe, raw, organic plant foods. That’ll be your best source. And don’t fall for that “plants today don’t have enough” talk. Where do you think the manufacturers get them? Magic?
There are those who prefer not to use vitamins and supplements. That’s a personal choice, but if you feel you should, or your nutrition advisor suggest that you do, go ahead.
A good vegan diet should provide you with what you need, but a little security for serious issues is a good thing.
