Cardiologist WARNS: NEVER Take B12 With THESE 2 Common Medications After 60 — It Can Be Harmful.

#VitaminB12 #HeartHealth #SeniorHealth
What if the vitamin you take every morning to support your health is actually being blocked by the medications you rely on after 60? In this video, Dr. Robert Harrison reveals a hidden and often overlooked issue involving Vitamin B12 and two of the most commonly used medications among older adults — Metformin and Proton Pump Inhibitors such as Omeprazole.

These medications may interfere with proper B12 absorption, potentially contributing to elevated homocysteine levels — a lesser-known marker associated with heart health, stroke risk, and blood vessel damage. What makes this especially concerning is that the process can happen quietly over time, often without obvious symptoms, and may not be detected in routine bloodwork.

If you are over 60 and taking medication for diabetes, acid reflux, or general health support, this is important information you should know. In this video, you’ll learn:

✔️ How common medications may interfere with Vitamin B12 absorption
✔️ Why standard lab tests may not always reveal the full picture
✔️ The connection between homocysteine, heart health, and brain function
✔️ Better ways to take B12 for improved absorption
✔️ Simple changes that may help reduce long-term risk

This video is especially helpful for seniors who want to stay healthy, mentally sharp, and independent as they age.
