Vitamin B12: symptoms that should alert you

Particularly vulnerable populations

Certain categories of people must be particularly vigilant:

• Seniors after 50 years : their intestinal absorption capacity gradually decreases.
• Followers of vegetarian and vegan diets : the main sources are animal.
• Individuals suffering from digestive pathologies : Crohn’s disease, ulcerative colitis or gluten intolerance.
• Patients taking specific medications : antacids, metformin or certain diabetes treatments.
• People who have had abdominal surgery : gastric bypass or intestinal resections.

Symptoms that reveal a deficiency

B12 deficiency can manifest itself in various ways:

• Persistent exhaustion and loss of muscle tone : as if your batteries were constantly flat.
• Dull or slightly yellowish complexion : result of deficient hemoglobin production.
• Tingling sensations in the extremities : a sign of early neurological damage.
• Cognitive problems and memory loss : difficulty concentrating, comparable to “brain fog.”
• Emotional instability : irritability, anxiety or depressive tendencies.
• Recurrent mouth inflammations : glossitis (sore tongue) or repeated mouth ulcers.
