Low B12 levels have been tied to “memory problems, confusion,” and even dementia-like symptoms. It also affects mood by lowering serotonin and dopamine, causing “depression, anxiety, irritability, or general mood swings.”
5. Mouth Pain and Vision Trouble
You may notice glossitis—a swollen, red, painful tongue—and mouth ulcers. In rare cases, optic nerve damage can lead to “blurred or double vision” and light sensitivity.
Who’s at Risk?
Higher-risk groups include older adults, vegans, people with digestive disorders (like Crohn’s), and those on certain medications like metformin.
Take Action
If you have these symptoms, see your doctor. A simple blood test can check B12 levels, and early treatment can prevent lasting damage.
Final Thought:
“Vitamin B12 might not get as much attention as other nutrients, but its impact on your body and mind is significant.”
