Vitamin B12 is essential for healthy life, playing a key role in the normal functioning of the brain and nervous system, whether you have diabetes or not. It’s found in food sources such as meat, fish, dairy products and eggs. B12 deficiency(anaemia) can be more common in older people not eating enough of these major food sources.
