Cortisol plays a central role in the body’s stress response, but chronic elevation can negatively impact sleep, mood, and metabolic health. The 8-week randomized, placebo-controlled study in a moderately stressed heterogeneous group of adults evaluated the effects of ThymoQuin supplementation on key markers of stress physiology, including cortisol, dehydroepiandrosterone (DHEA), sleep quality, and mood. Results showed a coordinated pattern of improvements, including a 23% reduction in cortisol, a 10% increase in DHEA, a 29% improvement in the DHEA:cortisol ratio (stress resilience), enhanced vigor, and a 31% improvement in sleep quality.
“Stress is a system-wide challenge,” said Morris Zelkha, CEO of TriNutra. “What makes this study so compelling is that ThymoQuin demonstrated a coordinated effect across cortisol balance, adrenal function, sleep, and perceived energy. These findings build on previous ThymoQuin research around cortisol balance, further establishing the ingredient as a multi-system solution for modern stress management.”
Cortisol and DHEA are key components of the body’s stress response, and their balance is often used as an indicator of how the body adapts to ongoing stress. In this study, changes in these markers were aligned with improvements in sleep quality and vigor, suggesting a broader pattern of physiological adjustment rather than an isolated effect.
Importantly, improvements in endocrine markers were aligned with meaningful benefits in sleep quality and subjective vitality, suggesting that ThymoQuin supports the body’s natural recovery processes rather than acting as a stimulant or sedative. The study also introduces the Stress Resilience Index (SRI), an emerging composite measure designed to capture multi-system adaptation across endocrine, psychological, and sleep domains. This approach reflects a growing shift in clinical research toward evaluating whole-body resilience rather than isolated biomarkers.
“As consumers increasingly look for solutions to manage and balance everyday stress, the industry needs ingredients backed by meaningful, system-level science,” said Zelkha. “ThymoQuin represents the convergence of traditional wisdom and modern clinical validation as an adaptogen for today’s stress challenges.”
