Low levels of other B vitamins, such as B12 and B9, usually accompany vitamin B6 deficiency. This can lead to biochemical changes. Here are some causes and treatment tips you should know.

Sore Tongue

A deficiency of vitamin B6 can lead to glossitis, marked by a red and swollen tongue. People with glossitis also have difficulty chewing, talking, and swallowing.

Skin Rashes

Adults who are deficient in vitamin B6 may suffer from red itchy rashes on their skin.

Mood Swings

Inadequate Vitamin B6 affects one's mood and can lead to mental issues like depression, irritability, anxiety etc.

Weakness And Fatigue

Vitamin B6 helps in oxygen circulation throughout the body. Inadequate oxygen levels can cause anaemia, which results in weakness and fatigue.

Weakened Immune System

Low levels of vitamin B6 reduce the production of antibodies, white blood cells, and other immune factors, which are essential for preventing infection, inflammation, and various cancers.


If you are deficient in vitamin B6, taking vitamin B6 supplements by mouth is advisable. Taking vitamin B6 supplements usually corrects the deficiency in adults.
