Should senior citizens take vitamin B12?

Yes, most seniors should take Vitamin B12 supplements or consume fortified foods because aging reduces stomach acid needed for absorption, leading to common deficiencies that impact nerve function, memory, and red blood cell production, potentially causing fatigue, weakness, or cognitive issues. While the daily need is 2.4 mcg, absorption from food is tricky, so supplements with free B12 are recommended, but always check with a doctor due to potential medication interactions and to determine the right dosage for you.

Is vitamin B12 safe for seniors?

The foods highest in Vitamin B12 are organ meats (like liver and kidney) and shellfish (especially clams), offering thousands of percent of the daily value in small servings, with fortified cereals, dairy, fish (salmon, tuna, sardines), and eggs also being excellent sources. For vegans, fortified foods like nutritional yeast and plant milks are key, as B12 is naturally found in animal products.
 

What medications affect the absorption of vitamin B12?

Common medicines affecting vitamin B12 absorption include Proton Pump Inhibitors (PPIs), H2-receptor antagonists (H2RAs), and the diabetes drug Metformin, all reducing stomach acid or altering gut function needed for B12 release and absorption, plus antiseizure drugs like phenytoin, anti-gout meds like colchicine, and some antibiotics. Chronic use can lead to deficiency, causing fatigue, nerve issues, or anemia, requiring monitoring by a doctor, says The Economic Times and the NHS. 

What is the cut-off for B12 in the elderly?

Thus, older adults with B12 deficiency may have a reversible or preventable form of cognitive deterioration if identified and treated timeously.

Also, avoid combining B12, folate, and B6 after a stent placement due to increased risk of blood vessel narrowing, and consult a doctor about other potential interactions like with chloramphenicol. 

What do you crave when your B12 is low?

B12 deficiency can cause specific food cravings, particularly for meat, fish, or eggs, as your body seeks sources of the vitamin, and may also lead to sugar cravings due to its role in serotonin and energy regulation, but it can also manifest as pica (craving non-food items like ice or even bleach in severe cases). These cravings signal your body trying to correct a nutrient imbalance, but clinical testing is needed for a proper diagnosis, as emotional factors also drive cravings.

What does B12 fatigue feel like?

B12 fatigue feels like extreme, persistent tiredness and weakness, a lack of energy even after rest, and "brain fog," often accompanied by shortness of breath, pale skin, pins and needles, and a sore tongue, because your body can't produce enough healthy red blood cells to carry oxygen.
