Normally we associate Vitamin B12 deficiencies with people on a vegetarian or vegan diet. But is this a true fact? No, it is not. People over the age of 50 have a lower stomach acid thus making it harder for the body to absorb the vitamin B12. The National Health and Nutrition Examination Survey found that an estimated 3.2 percent of adults over the age of 50 have a severely low B12 level, and up to 20 percent may have a borderline deficiency. Some sources claim that 50 percent of older people have a deficiency. For some, no matter how much animal products you eat you will not get enough vitamin B12.
Alcohol and B12
Alcohol no matter how you look at it may damage the lining of your stomach. Even though you may only drink in moderation- this is something that your stomach does not care about. The damage to the stomach lining will decrease the gastrointestinal tracts ability to absorb vitamin B12.
Alcoholism changes the way in which many nutrients, including B12, are transported and stored in the body, as well as how they are excreted. This according to the National Institute on Alcohol Abuse and Alcoholism.
B12 and acid reflux
Stomach acid is needed to absorb vitamin B12 and commonly prescribed acid reflux drugs reduce the acid production in the stomach. And we see deficiency risk in people taking these heartburn medications. Also, digestive conditions such as Celiac disease and Crohn’s disease makes it hard for your body’s ability to absorb vitamin B12.
B12 – veganism and vegetarianism
If you are a vegetarian or vegan you could have a hard time getting vitamin B12. Even if you are a vegan or vegetarian for moral reasons you can get B12, by supplementation. Vitamin B12 supplements are among the safest supplements out there. It would be very hard for you to overdose on this vitamin since it is water-soluble. Any excess B12 is eliminated through the kidneys.
