What are the symptoms of vitamin B12 deficiency?

Vitamin B12 is an indispensable trace element for the human body. If there is a lack of vitamin B12, it will easily lead to memory loss and pale complexion. These people are more likely to have psychological problems such as anxiety and depression.

1. Memory loss: Do you often suffer from memory loss? At this point you may be worried about whether you have early-stage Alzheimer's, but in fact it may be a lack of vitamin B12 that is at work.

2. Paleness: If your originally rosy complexion gradually turns sallow, a lack of vitamin B12 may be the culprit. Insufficient red blood cells in your blood vessels make you very fragile, and a lack of bilirubin pigment causes your skin to turn yellow.

3. Smooth and red tongue: About half of people who are severely deficient in vitamin B12 lack the milky protrusions on their tongue, especially on the edges of the tongue. This is accompanied by a burning sensation, especially under the tongue. Since most of the papillae contain taste buds, you lose the ability to distinguish flavors.

4. Anxiety and Depression: Do you feel more depressed or anxious than usual? A B12 deficiency ruins your mood and can lead to depression or anxiety. Because vitamin B12 is involved in the synthesis of brain chemicals such as serotonin and dopamine, which help regulate mood.

5. Vision impairment: Lack of B12 can damage the optic nerve or block the blood vessels on the retina, leading to blurred vision, photophobia, and even blindness. Timely and appropriate supplementation of vitamin B12 can relieve the symptoms.
