Synopsis

Source of validity: Scientific
Rating (out of 5): 3

Vitamin C (ascorbate) has a well-established role in adrenal gland function, including the adrenal medulla. The adrenal glands, particularly the adrenal cortex and medulla, contain some of the highest concentrations of vitamin C in the human body. Scientific studies have shown that vitamin C is involved in the biosynthesis of catecholamines (such as adrenaline and noradrenaline) in the adrenal medulla. Specifically, vitamin C acts as a cofactor for dopamine β-hydroxylase, an enzyme that converts dopamine to norepinephrine, a critical step in catecholamine synthesis. Animal studies and limited human studies indicate that vitamin C levels may decrease in response to physiological stress, which stimulates adrenal activity and catecholamine output. Supplementation with vitamin C has been shown in some models to support adrenal function during stress, though the direct clinical benefits in healthy humans remain less clear.

While there is scientific validation for the biochemical necessity of vitamin C in adrenal catecholamine synthesis, robust clinical trials demonstrating significant benefits of supplementation for adrenal medulla support in the general population are limited. Most evidence supports its role in conditions of deficiency or increased physiological demand (e.g., stress). Thus, the use of vitamin C for adrenal medulla support is grounded in its biochemical function, with moderate scientific support but lacking large-scale clinical outcome trials.
