So the question of wether it is necessary to take supplements or not will be discussed in this post. My simple answer to this question is YES, I recommend taking following 4 Supplements: Vitamin B12 Vitamin D3 Omega 3 (DHA, EPA) Iodine Important to mention here is the fact that this recommendation is not only for people on a vegan diet but also for people on an omnivorous diet.
