The only supplements that I can determine that are required on a plant based diets are B12 and EPA/DHA which source is lab grown algae.
The cheapest way to get our B12 is probably one 2500 microgram sublingual, chewable, or liquid supplement of cyanocobalamin once a week.

Don’t buy me.
- Methylcobalamin Form of B-12 (this type of B-12 is not good)
I buy this one. It is a two year supply. I have no affiliation with Swanson.
I take this once a day.
