Vitamin B complex, particularly vitamins B6, B12, and pantothenic acid (vitamin B5), has a scientifically supported role in supporting the adrenal medulla, though the evidence is moderate rather than robust. The adrenal medulla is responsible for producing catecholamines such as adrenaline and noradrenaline in response to stress. Vitamin B5 is especially notable, as it is a precursor for coenzyme A, which is essential in the synthesis of adrenal hormones. Some animal and in vitro studies indicate that B vitamins are necessary for optimal adrenal function and hormone production. For instance, pantothenic acid deficiency in animals leads to impaired adrenal function and decreased production of adrenal hormones. Additionally, B vitamins play a general role in energy metabolism and the body's stress response, both of which are linked to adrenal activity.

However, high-quality human studies specifically examining the effect of B vitamins on the adrenal medulla are limited. Most clinical evidence relates to the broader effects of B vitamins on stress and energy metabolism rather than direct effects on adrenal medulla hormone output. The use of B vitamins for adrenal support is also present in some traditional naturopathic and integrative medicine practices, but the main justification remains based on biochemical roles and indirect evidence rather than direct clinical trials. Overall, there is moderate scientific support for vitamin B's role in supporting the adrenal medulla, primarily through its involvement in hormone synthesis and the stress response.
