Neurological symptoms of vitamin B12 deficiency can be as far reaching as general weakness, difficulty controlling the bladder and bowel, memory loss, numbness or tingling in the hands or feet, and even dementia, depression, psychosis and seizures. It can be very serious if we do not take adequate action to ensure regular intake and many of the symptoms are irreversible even once the deficiency is treated.
Our bodies can store B12 for 3 to 5 years, so people following a vegan diet and not regularly taking B12 supplements may not realise they're not consuming enough for quite some time. Eat Sustainably recommend you seek seeking individual advice from an Accredited Practising Dietitian or your GP if you are pregnant, breastfeeding or have children on vegan diets.
