What issues?
Vegan milks, meats, etc are fortified with everything hard to get and most macro levels are naive and based on studies performed on the general population/omnivores. It’s actually harder as a vegetarian as you don’t get the metabolic pathway benefits like the improved omega6 conversion. This is why you don’t get actual negative outcomes shown for low levels of certain nutrients in vegans.
It’s effortless unless you’ve got a selective eating disorder. Just chuck some flax and nooch in sauces and you’re good to go.
