Fair questions
Does Rhodiola rosea work?+
For endurance, it is not settled. Results lean positive, but there is not much yet.
Is Rhodiola rosea safe?+
No caution is recorded on this page. That is not a safety guarantee; the studies we read were not safety trials.
Why only 1 source, when PubMed lists 50?+
The 50 is every paper that mentions Rhodiola rosea in any way: animal studies, blood measurements, papers where it is a side note. The strongest sources are combined reviews, and each one already gathers every trial its authors could find. Our 1 cover 13 trials between them, and every one is linked above. Both counts are measured, not estimated.
