What it is
Rhodiola rosea is a small flowering plant that grows in cold, high places: the Arctic, Scandinavia, Siberia and mountain ranges of Europe and Asia. The root has been used for centuries in Scandinavian and Russian tradition. Extracts are usually described by two groups of compounds, rosavins and salidroside.
What studies observed
In 60 adults with fatigue, 28 days of a rhodiola extract (576 mg a day of the SHR-5 extract) improved fatigue levels and attention compared with placebo (Olsson et al., 2009).*
In an earlier trial, 56 physicians on night duty took rhodiola extract for two weeks and scored better on tests of mental fatigue: associative thinking, short-term memory and concentration (Darbinyan et al., 2000).*
In this formula
A serving has 150 mg of rhodiola rosea. The amounts above are per serving, from the Supplement Facts panel. Research cited on this page studied the ingredient on its own, usually in a different form or dose, and is not a claim about this product.
Good to know
Rhodiola is usually taken earlier in the day. Talk to your healthcare provider before taking any supplement if you are pregnant, nursing, taking medication or have a medical condition.
