Vitamin B12: Why Your Levels Matter in 2026
Vitamin B12 is essential for healthy nerves, brain function, and red blood cell production. Yet deficiency remains common worldwide and can lead to fatigue, memory problems, balance issues, anaemia, and even permanent nerve damage if not detected early.
In this video, we explain in simple terms:
• Why vitamin B12 is vital for brain and nerve health
• What a very large population study (84 million tests) has shown
• Who is most at risk (older adults, vegetarians, people on metformin or acid-reducing drugs, and those with gut conditions)
• How to increase B12 through diet (non-vegetarian and vegetarian options)
• When supplements or injections may be needed
• Why mega-dose advertising can be misleading
• How often B12 should be tested
• Why B1 and B6 can also be low together with B12
Key message:
Test first, treat if low, then maintain — do not guess and do not megadose without medical guidance.
This video is for education only and is based on scientific evidence. Always discuss testing and supplementation with your doctor.
