I'm not a vegetarian, I don't eat red meat, but I do eat a lot of poultry (white chicken meat, eggs),yogurt, and cheese in moderation. I also take b12, and for the past year i've been taking about 1,000 mcg's a day and I was thinking of upping it to 2500 mcg's or even 5,000. I hear too much b12 can have adverse digestive effects etc etc, any answers would be helpful.
