The claim that “cardiologists warn never to take B12 with these 2 common medications after 60” is a common style of online health headline, but it is misleading without specific medication names and medical context. There is no general rule that people over 60 should never take vitamin B12 with two particular common medications.
However, some medications can interact with vitamin B12 levels or absorption, especially in older adults:
- Metformin (commonly used for type 2 diabetes)
- Long-term use can reduce vitamin B12 absorption and may contribute to B12 deficiency.
- Doctors sometimes monitor B12 levels in people taking metformin.
- Acid-reducing medications (such as proton pump inhibitors and some H2 blockers)
- Examples include long-term use of medicines that reduce stomach acid.
- Lower stomach acid can make it harder for the body to absorb B12 from food.
Other considerations:
- High-dose B12 supplements are usually considered safe, but people with certain medical conditions or abnormal lab results should discuss dosing with a clinician.
- If someone takes multiple medicines, the issue is usually monitoring and correcting deficiencies, not automatically avoiding B12.
If you share the two medications named in the warning (or paste the article/video text), I can check whether the claim is accurate and explain the actual interaction.
