Rhodiola (Rhodiola rosea, also called golden root or arctic root) is a plant from cold, high-altitude regions whose root has been used traditionally for fatigue, endurance and mood. Today it is promoted for stress, energy, mood, thinking and athletic performance.
Also known as: Rhodiola rosea, golden root, arctic root, rose root.
Rhodiola has no intake value or upper limit, and the NIH National Center for Complementary and Integrative Health (NCCIH) does not give a standard amount. Extracts are standardized to different compounds, so amounts are not comparable across products.
It is sold in the US as a dietary supplement. Under the 1994 dietary supplement law (DSHEA), FDA does not approve dietary supplements before they are marketed, and the maker, not FDA, is responsible for safety and labeling. There is no FDA-approved rhodiola drug.
NCCIH says there is not enough reliable evidence to determine whether rhodiola or its components are useful for any health purpose; most research in people is of low to moderate quality.
NCCIH says rhodiola is possibly safe for up to 12 weeks. Side effects may include dizziness, headache, insomnia, and dry mouth or excess saliva. Interactions with losartan, a blood pressure drug, have been reported. Little is known about its safety in pregnancy or while breastfeeding.
We could not find a single published half-life or time to peak for rhodiola that applies to a supplement dose, so we do not list one.
