When B12 levels are low, the signs can be varied: Anemia: fatigue, weakness, pale skin, and dizziness Fatigue: a deep-seated weariness that doesn't improve with rest Nerve Damage: tingling or numbness in hands and feet, balance problems, and memory loss (seek medical advice promptly) Mood Disturbances: depression, irritability, and personality changes While our bodies can store B12 for years, some groups are more susceptible to deficiency, often because of absorption issues rather than diet
