Did you know that Spirulina….
Vitamin B12 is deficiency more common in vegans and some vegetarians because B12 is found in animal products. If you are feeling really tired and rundown, you might not be getting enough.
But you already knew that. What I did not know that there is no whole food source of B12 for vegans, except for spirulina which is blue green algae that also has iron in it.
