What is the difference between being vegan and vegetarian?
Vegetarians do not eat meat, and depending upon their morals or preferences, may or may not eat eggs or dairy. Most commonly, they do eat eggs and dairy.
Vegans do not consume, use, or buy any product derived from animals, including eggs, milk, honey, leather, wool, beeswax, and anything dyed red, in case it’s an insect based dye.
Nutritionally, the only difference is that vegans need to take a B12 and amino acid supplement, since they have no dietary source of these nutrients.
You can get all the nutrients you need on a lacto-ovo (eggs and milk) vegetarian diet without supplements.
