Carla Kaufman“ The only food source of b12 is from animal products.”
You are incorrect. B12 is only produced by bacteria please stand down.
“ Vitamin B12 (Cobalamin) is a complex cobalt-based organic compound that is produced naturally only by bacteria, especially those that are anaerobic (e.g., environments that lack oxygen such as large intestine). Animals, plants, or fungi don’t have the enzymes to produce B12.”
