Vitamin B12 deficiency

vitamin b-12 in the United States have had enough of this nutrient. If you're unsure, you can ask your doctor if you should have a blood test to check your vitamin B12 level.With age, it can become more difficult to absorb this vitamin. It can also happen if you have had weight loss surgery or another operation that removed part of your stomach, or if you drink a lot.

I have taken some medications that interfere with the absorption of vitamin B12. This includes some heartburn medications, including proton pump inhibitors (PPIs) such as esomeprazole Natural treatment of ED  lansoprazole (Prevacid), omeprazole (Prilosec OTC), pantoprazole (Protonix) and rabeprazole (Aciphex), H2 blockers such as cimetidine (Tagamet) and famotidine  and some diabetes medications such as metformin 

You may also be deficient in vitamin B12 if you are on a vegan diet (which means you don't eat animal products, such as meat, milk, cheese, and eggs) or if you are a vegetarian and don't eat enough eggs or dairy products to meet your vitamin B12 requirement. Either way, you can add fortified foods to your diet or take supplements to meet this need. Learn more about the different types of vitamin B supplements.
