Data coverage and detailed study classifications

Paper counts are separated by research topic below. One paper may contribute to multiple findings.

Analysis status: Public-ready

Ingredient analysis date:

How the grade was determined: B

The 60.9 evidence score includes 8 independent human studies and 8 clinical studies in the representative benefit area. The B tier remains conservative because of limited repetition across independent human clinical studies.

The grade is based mainly on the research area with the most evidence. It does not mean the same result was found in other areas.

Side effects and combination findings

Findings from this ingredient alone are shown separately from those involving another supplement or medication.

No reviewed caution rules are available yet. Reported caution findings are shown below.

Review 1 combination findings and 0 findings that outperformed an ingredient alone.

Findings to review with care

Side effects reported for the ingredient alone are separated from findings involving another supplement or medication.

Cautions reported with another supplement or medication

These studies reported worsening outcomes, reduced absorption, or other cautions with combined use. They do not predict an individual's outcome.

SSRIsPotential risk of serotonin syndrome when combined with SSRIs.
Tricyclic antidepressantsPotential risk of serotonin syndrome when combined with tricyclic antidepressants.

Reported improvements with combinations

Combination findings are grouped by how the study compared them. This is not a recommendation to combine ingredients.

Combinations with reported improvement

The combination showed improvement, but each ingredient's contribution is unclear.

CaffeineA randomized, double-blind, placebo-controlled trial in 48 male volleyball players found that combined Rhodiola rosea and caffeine supplementation significantly improved jump height, reduced power decline during high-frequency jumps, and lowered perceived exertion compared to placebo and single-agent groups.
