Will all my B12 deficiency symptoms resolve with treatment
People with low B12 may experience: Persistent fatigue or low energy Weakness Brain fog, concentration issues, or memory changes Low mood or irritability Pins and needles, numbness, or nerve-type sensations Mouth ulcers or a sore tongue Paleness or shortness of breath (if anaemia is present) Some symptoms can become more serious if deficiency is prolonged, particularly neurological symptoms
Oral vitamin B12 is generally safe to take at recommended doses
