Vegans only need multivitamins and omega 3s for supplementation, that’s it.

I'm not vegan, I'm vegetarian, but I don't need any supplements to be just fine. I know plenty of vegans who are happy and healthy without supplements. It isn't that hard to find sources elsewhere in your diet. I've never understood the malnutrition argument, when we've known that you can be perfectly healthy (and statistically healthier than otherwise) when eating vegan. You can't just eat salads and expect to be okay, but doesn't that sound like such a bland diet anyways? I prefer making stir fries, burritos, stews, and other mixed dishes where I can hit all the macro and micro nutrients my body needs. I'm very healthy and haven't eaten meat or animal products outside of humanely sourced eggs (my friend has chickens) for years.
