It looks like you’re sharing a headline. If you’re asking whether it’s true, the claim is overstated.
Vitamin B12 is generally safe and is commonly recommended for older adults because B12 deficiency becomes more common with age. However, some medications can affect B12 levels or absorption, so timing and monitoring can matter.
Two common medication groups often discussed with B12 are:
- Metformin (commonly used for type 2 diabetes)
- Long-term use can reduce B12 absorption in some people. Doctors may check B12 levels periodically, especially in older adults or those with symptoms of deficiency.
- Acid-reducing medicines such as proton pump inhibitors (PPIs) and some H2 blockers (used for reflux/heartburn)
- Long-term use may reduce stomach acid needed to absorb B12 from food, potentially lowering B12 levels.
This does not mean people over 60 should “never take B12” with these medicines. Many people take B12 supplements while using these drugs under medical guidance. The right approach depends on your medication, dose, duration of use, diet, kidney function, and B12 level.
If you share the two medications named in the video/headline (or your own medications), I can help check whether there is a known interaction or concern.
