What the trials show about timing.

Time-to-effect windows the engine read from the trial record. Each is a window a named study measured, cited and dated, never written by the brand.

• Siberian Rhodiola (Rhodiola rosea) root extractwithin the same test session after a single doseMeasured within a day

  A randomised double-blind placebo-controlled trial in 161 military cadets aged 19 to 21 measured capacity for mental work after a single dose of the standardised SHR-5 extract taken against a background of fatigue and stress. The antifatigue index was 1.0385 and 1.0195 for the two active doses against 0.9046 for placebo, a difference the authors report at p below 0.001 for both doses, with no significant difference between the two doses. The measure was a psychometric test score, not a subjective report.

• Siberian Rhodiola (Rhodiola rosea) root extractabout two to four weeks of daily useBuilds with daily use

  Two placebo-controlled trials measured the same daily-use window from different ends. In a phase III parallel-group trial, 60 adults aged 20 to 55 diagnosed with fatigue syndrome took 576 mg per day of the SHR-5 extract or placebo, assessed on day 1 and after 28 days. The active group differed from placebo on the Pines burnout scale, on three attention indices, and on the saliva cortisol response to awakening. In a double-blind crossover trial, 56 physicians on night duty took one low-dose tablet daily and showed a significant improvement in mental fatigue tests during the first two-week period. Both trials were conducted with the extract manufacturer, the Swedish Herbal Institute, among the authors.

• Rosavins

  Nobody has timed rosavin by itself. Studies of the whole root extract run one to four weeks of daily use before measuring anything.
