Vitamin B12 deficiency is a common occurrence among people and because it helps serve several bodily functions, many resort to supplements. Since the body does not produce it naturally and one may miss out on the foods that possess this essential nutrient, supplements seem to be the best available alternative.
However, experts recommend getting your vitamin B12 from food, before trying a supplement. If you’re someone who has eliminated meat, dairy and fortified cereals from your diet, then it is possible that you may require supplements. However, it is best to talk to your dietician or physician.
Mostly, vitamin B12 is advised to be taken in the morning or with a meal, since it is associated with energy metabolism, which may interrupt your sleep if taken at night. Experts recommend taking B12 supplements with a glass full of water to optimize absorption.
