why do you think the reason for them becoming vegan has something to do with B12 levels? likely they became vegan for different reasons, became much more aware of the importance of B12 and started taking a supplement.
every vegan should supplement b12, so they probably do too
> Fortunately today’s vegan communities are much more aware of this so I started taking these supplements right up front and all my blood markers improved dramatically since when I consumed meat/dairy.
Yeah but that sentence does not refer to why the person switched to being vegan, the first one does. In any case, let us not beat the dead horse there. :P Supplement B12 and it is fine.
No sentence referred to why they became vegan. Their nutrient numbers improved when they became vegan. This happened because becoming vegan moved them from a group who didn't know they needed supplements to a group who knew they needed supplements.
