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.
It’s annoying to hear some push back against this when it’s as simple as taking relatively safe supplements (just make sure you talk to a doctor, and not a social media influencer, about how much you should take, and if you get a chance to regularly check your bloodwork don’t miss out).
