7 Silent Signs You May Have Vitamin B12 Deficiency

You may think it’s just stress or a busy schedule, but persistent tiredness can be a sign of low B12 levels. Vitamin B12 is crucial for energy production, and a deficiency may leave you feeling drained even after a good night’s rest.

Struggling with concentration or memory problems could indicate a lack of Vitamin B12. This vitamin plays a key role in brain function and cognitive health. If you find yourself forgetting things more often, B12 deficiency may be the culprit.

A B12 deficiency can damage the nerves, leading to feelings of numbness or tingling, especially in your hands and feet. This condition is known as "peripheral neuropathy" and requires attention.

Vitamin B12 helps produce red blood cells, and a deficiency can lead to anemia. If your skin looks paler than usual or has a yellowish tint (jaundice), it may signal a B12 deficiency.

Low B12 can lead to anemia, which reduces the number of red blood cells needed to carry oxygen throughout your body. This can result in shortness of breath, even during mild physical activities.

Vitamin B12 plays a role in producing brain chemicals that regulate mood. A deficiency might lead to feelings of depression, irritability, or anxiety, even without any clear external cause.

A swollen, inflamed tongue (glossitis) or recurring mouth ulcers can be signs of B12 deficiency. This happens because B12 is necessary for proper cell growth and repair, including cells in the mouth.
