Our bodies need B12 to make red blood cells , which carry oxygen through the body. Not having enough B12 can lead to anemia, which means your body does not have enough red blood cells to do the job. This can, not only make you feel weak and tired but can also cause damage to your nerves and affect your memory.
Vitamin B12 also helps to build your immune system, and if you're pregnant or trying to get pregnant, your intake is extremely important
Vitamin B12 is found in animal foods, such as meat, seafood, milk products, poultry, and eggs. It is not in foods from plants unless it has been fortified, like some cereals, are fortified with vitamin B12.
Since we obtain vitamin B12 only from animal foods in our diet, deficiencies tend to develop among strict vegetarians and vegans, especially vegan children, who eat no animal products. However, the elderly, and those who are unable to absorb vitamin B12 from the intestinal tract are also at B12 deficiency risk.
Symptoms of Vitamin B12 Deficiency
Vitamin B12 absorption and/or depletion may occur in those;
who use alcohol excessively
who take antibiotics
who use stomach-acid controlling drugs, including H-2 blockers and proton pump inhibitors
who take Metformin to treat type 2 diabetes
who use Nicotine products
Which B12 supplements are good?
Your B12 supplement should be "sublingual" (meaning it melts under-the-tongue), and should be made with methylcobalamin, which is the natural kind of B12 that comes from bacteria and is more readily used by your body.
You can also get shots of vitamin B12. These shots are given once every week for a month and after this, a shot is given once every month. But this all depends on your deficiency level and your doctors recommandation.
Vitamin B12 is considered safe and non-toxic, so it's not a problem if your supplement contains more than the amount you need, what your body doesn't use is just flushed away.
