WHAT TO EXPECT - HONESTLY
Why it’s in: chosen over ashwagandha deliberately - better tolerated for daily use, well-evidenced for stress and fatigue at 200mg per the trials we cite.
EVIDENCE: 4 RCTS CITED - MECHANISM: HPA-AXIS MODULATION - FULL PAGE >Because a daily formula should replace a shelf, not join it. Every ingredient earns its place with published evidence and a clinical dose - the full reasoning is in the formula changelog.
THE FIT CHECK - 60 SECONDS - 4 QUESTIONS
Is Rōnin for you?
Four honest questions. If the answer is no, we will tell you no - and why. A supplement you take every day should be a considered decision, and it is not right for everyone.
