Signs You Might Have a Vitamin B12 Deficiency

Feeling exhausted despite sleeping well? You could be low on vitamin B12—a key nutrient that helps

deliver oxygen through your blood. Without it, you may feel weak, sluggish, and short of breath.

Other common symptoms include tingling or numbness in the hands and feet, pale or yellowish skin, and a red, swollen tongue (glossitis).

B12 is crucial for brain health, so low levels can also lead to memory problems, trouble concentrating, mood swings, anxiety,

or depression. In severe cases, it can damage nerves, causing coordination issues, muscle weakness, or even vision problems due to optic nerve damage.

B12 deficiency is more common than people realize, especially in people over 50, vegans, those with digestive

disorders like Crohn’s or celiac, and anyone taking medications like metformin or proton pump inhibitors (PPIs).

What to Do:

Eat B12-rich foods (meat, fish, dairy, eggs, fortified cereals).

Take supplements if you’re at risk.

Get regular blood tests if you experience symptoms.

Talk to a doctor for diagnosis and treatment.

Bottom Line: Don’t ignore the signs. B12 deficiency is treatable—and correcting it can boost your energy, mood, and overall well-being.
