9 effects of vitamin B12 deficiency! (Page 2 ) | May 18, 2025

5. Balance and Coordination Problems
As nerve damage progresses, it can affect your motor control. You may see unsteadiness when walking, frequent stumbling, or difficulty with coordination. This effect is particularly dangerous in older adults, as it can grow the risk of falls and related injuries.

6. Memory Loss or Cognitive Decline
Low levels of vitamin B12 have been connected to memory problems, confusion, and even dementia-like symptoms in severe cases. The vitamin plays a vital role in brain function, and long-term deficiency can impact concentration, thinking, and overall mental clarity.

7. Mood Changes: Depression and Irritability

Vitamin B12 influences the production of brain chemicals like serotonin and dopamine, which are crucial for regulating m00d. A deficiency can cause depression, anxiety, irritability, or general m00d swings. Several studies recommend that B12 supplementation may boost mood in individuals with low levels.

8. Glossitis and Mouth Ulcers
B12 deficiency can cause glossitis—a swollen, red, and painful tongue. It can alsocáue mouth ulcers, a burning sensation in the mouth, or even a reduced sense of taste. These effects can make eating and speaking uncomfortable and may be mistaken for other conditions at first.

9. Blurred or Disturbed Vision
In rare cases, vitamin B12 deficiency can affect your vision. Damage to the optic nerve (optic neuropathy) can result in blurred or double vision, sensitivity to light, or visual disturbances. Though uncommon, this effect is a warning sign that your deficiency is becoming severe.

Who’s at Risk?

Certain groups are more likely to suffer from vitamin B12 deficiency, including:

People over 60 (due to reduced stomach acid production)
Vegans and vegetarians (B12 is mostly found in animal products)
Individuals with digestive disorders (like Crohn’s or celiac disease)
People taking certain medications (like metformin or acid reducers)
What You Can Do
If you’re suffering from any of the above symptoms—especially if you fall into one of the higher-risk categories—it’s a good idea to talk to your healthcare provider. A simple bl00d test can check your vitamin B12 levels.

Final Thoughts
Vitamin B12 might not get as much attention as other nutrients, but its impact on your body and mind is significant.
