Not sure if I'm getting enough omega-3 as a vegan but hopefully. Eat quite a bit of nuts, and ground flax every morning. I take an algae-oil supplement for EPA and DHA, but not sure if there's some other easy addition to my diet.
This is my biggest uncertainty with a vegetarian diet as well. Algae oil seems like the best bet but has much less DHA than fish oil, is more expensive and doesn't have as many studies yet from what I can tell.
