The headline “Cardiologist warns: never take B12 with these 2 common medications after 60” is likely an attention-grabbing claim rather than a general medical rule. There is no universal warning that people over 60 should never take vitamin B12 with certain medications, but some medications can affect B12 levels or change how the body uses it.
Common medication groups associated with lower vitamin B12 levels include:
- Metformin (commonly used for type 2 diabetes)
- Long-term use can reduce B12 absorption in some people.
- Doctors may monitor B12 levels, especially if there are symptoms such as numbness, tingling, fatigue, or anemia.
- Acid-reducing medications (such as proton pump inhibitors and some H2 blockers)
- Examples include medicines used for reflux or ulcers.
- Long-term use may reduce stomach acid needed to release B12 from food, which can contribute to deficiency.
This does not mean B12 supplements are dangerous with these medications. In many cases, supplementation may actually be considered if a deficiency is found.
A few cautions:
- Check with a healthcare professional before taking high-dose supplements if you have kidney disease, certain medical conditions, or take multiple medications.
- B12 deficiency is more common with age, so testing may be appropriate when symptoms or risk factors are present.
- Avoid stopping prescribed medications because of a headline.
If you tell me the two medications named in the article (or your own medications), I can help explain whether there is a real interaction or just a misleading warning.
