Short answer: KSM-66® Ashwagandha Root is an adaptogenic herb studied for a possible role in supporting cortisol balance and stress response, while Tribulus Terrestris is a traditional botanical the brand describes as standardized to 45% saponins.
Why these two ingredients address genuinely different roles
Ashwagandha's role centers on cortisol and stress response, while Tribulus's role centers on broader, mixed vitality research — two complementary, not overlapping, contributions.
Why Tribulus's evidence is described honestly, not oversold
Broader clinical research on it remains mixed — a direct, unhedged acknowledgment worth appreciating rather than a vague, confident claim.
💡 Worth knowing: KSM-66 Ashwagandha and cortisol research is cited directly from PubMed on the site's own evidence page.
