How vitamin B12 deficiency manifests itself in the body

Where can you find it, exactly?

Vitamin B12 is mainly found in foods of animal origin: beef liver, oysters, herring, eggs, cheeses

such as Emmental or Camembert, etc. If you are vegetarian or vegan, it may be more difficult to absorb enough. In this case, supplements are a solution recommended by health professionals.

At the slightest warning, it is best to consult a health professional to take stock and stay in good shape all year round.
