Vitamin B6 (pyridoxine) has some scientific basis for its use in supporting the nervous system, though the evidence specifically for "nervous exhaustion" is limited and not robust. Pyridoxine is an essential cofactor in the synthesis of various neurotransmitters, including serotonin, dopamine, and gamma-aminobutyric acid (GABA), all of which play key roles in maintaining normal nervous system function and mood regulation. Deficiency in vitamin B6 can lead to neurological symptoms such as irritability, depression, and confusion. Some studies have shown that supplementation with vitamin B6 may help alleviate symptoms of mild depression, premenstrual syndrome (PMS), and stress-related symptoms, which can overlap with what is sometimes described as "nervous exhaustion." However, there is limited research specifically addressing the effect of B6 on the broad, non-specific condition of "nervous exhaustion."

Traditionally, "nervous exhaustion" is a loosely defined term historically associated with symptoms like fatigue, anxiety, and low mood, and is not widely used in modern medical diagnosis. While vitamin B6 is often included in B-complex formulations marketed for stress and nervous system support, clinical trials directly evaluating B6 for "nervous exhaustion" are lacking. The available evidence supports its use in preventing deficiency and possibly improving mood in certain populations, but does not strongly validate its use as a primary treatment for nervous exhaustion.
