Earlier this 12 months, the Nationwide Institute for Well being and Care Excellence (NICE) reported that 6% of the inhabitants beneath 60 had vitamin B12 deficiency, rising to 11% amongst vegans.
Though Carly nonetheless ate cheese and eggs and drank milk, her consumption throughout these years of vegetarianism was not sufficient and her vitamin B12 ranges had dropped.
