Vitamin B12 deficiency: 6 common signs and symptoms to watch out for | Health

Vitamin B12 deficiency is more common in elderly compared to young across the globe but vegans and vegetarians are more at risk of developing it. This is the reason at least 47% Indians have Vitamin B12 deficiency as they many of them either stay away from non-vegetarian food or consume it less frequently. An important micronutrient, Vitamin B12 can have a significant effect on various body functions. Since our body doesn’t naturally produce it, one must add its sources to the diet. Vitamin B12 is mainly found in animal products like dairy, meat and eggs. People who are vegetarians or vegans can have Vitamin B12-fortified foods or supplements to meet the required Vitamin B12 levels. This vitamin is stored in the liver for up to 5 years and if you are at risk of eventually becoming deficient if your diet doesn’t help maintain the levels.
