B12 absorption is finicky, and meats contain rather small amounts. Injections and sublinguals are actually better at increasing levels than meat.

  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.
