Organ meats such as beef liver provide a significant amount of B12. If you are just eating muscle meat, then you will have to eat a lot.

  Excess liver consumption is a risk factor for vitamin A toxicity though, and the B12 amount varies wildly. Red meat consumption also increases cancer risk. It’s safer to take supplements from a reputable source.
