Synopsis

Source of validity: Scientific
Rating (out of 5): 2

Tyrosine is an amino acid that serves as a precursor to catecholamines, including dopamine, norepinephrine, and epinephrine, all of which are synthesized in the adrenal medulla. The rationale for using tyrosine to support adrenal medulla function is primarily grounded in its biochemical role as a substrate for these neurotransmitters and hormones. Several studies have examined the effects of tyrosine supplementation under conditions of acute stress (such as cold exposure, sleep deprivation, or military training), finding that it may help mitigate declines in cognitive performance by supporting catecholamine synthesis during periods of increased demand.

However, while these findings suggest a mechanistic link between tyrosine supplementation and adrenal medulla activity, clinical evidence for routine use of tyrosine to "support" adrenal medullary function in healthy individuals is limited. Most studies focus on short-term, high-stress scenarios rather than chronic use or general adrenal health. There is little evidence that supplemental tyrosine is needed or beneficial for adrenal medulla function under normal physiological conditions. Thus, while the use is scientifically plausible and has some supportive evidence in acute settings, the overall strength of evidence is modest, justifying a rating of 2 out of 5.
