Many animals are capable of synthesizing these compounds, but humans are not. Our bodies stopped producing them since we could get them through our omnivorous diet.

Vegans can of course take supplements for these, so you can get enough of them, but you do have to think about it and take the right supplements to prevent deficiencies.

All those plant based alternatives are significantly lacking in most of those nutrients, and aren't readily absorbed from plant based sources. You have to eat a shitton of them to reach the levels easily attained by eating a few animal products. Most vegans are absolutely deficient in them.

And for more you have Iron and Zinc which our bodies don't readily absorb from plant based sources.

Calcium and cholesterol are signifantly lacking in vegan diets. Carnatine and carnosine. The other vitamin Bs.

This is a blanket truism for any diet.

Sure, but it's extra true for vegan diets due to our bodies inability to fully digest most plants, and readily absorb the necessary nutrients from them.
