Vitamin B5, also known as pantothenic acid, plays a critical role in the synthesis of coenzyme A, which is essential for fatty acid metabolism and energy production within the body. The adrenal cortex requires coenzyme A for the biosynthesis of steroid hormones, including cortisol, which is central to the body's stress response. There is some scientific rationale for the use of Vitamin B5 to support adrenal function, primarily based on its involvement in steroidogenesis.

Animal studies (e.g., in rats) have shown that pantothenic acid deficiency can lead to impaired adrenal function and reduced production of adrenal hormones. Early research from the 1950s and 1960s suggested that supplementation could support adrenal health, particularly under conditions of stress. However, robust clinical trials in humans are lacking. No high-quality, large-scale studies have demonstrated that Vitamin B5 supplementation has direct, significant benefits for adrenal cortex function in healthy individuals or those with adrenal fatigue/exhaustion syndromes.

In summary, while there is a biochemical basis and limited animal data supporting the role of Vitamin B5 in adrenal hormone synthesis, the direct evidence in humans is weak. Thus, its use for adrenal cortex support is based on plausible scientific reasoning but is not strongly validated by clinical research.
