Rhodiola (Rhodiola rosea) thrives in the cold, mountainous regions of Europe, Asia, and the Arctic at high altitudes. Traditionally, northern communities have used it to address anxiety, stress, fatigue, anemia, sexual impotence, infections, headaches, and depression. It's also been employed to boost physical endurance, work performance, longevity, and resistance to altitude sickness.
Today, Rhodiola is popular as a dietary supplement for enhancing energy, stamina, and strength. It may offer nootropic effects, potentially improving attention, memory, and stress resilience. Typically, it's taken as root extracts in capsules or tablets.
Human studies on Rhodiola are limited in number and quality, making it challenging to draw firm conclusions on its efficacy.
Two review articles from 2011 and 2012 analyzed 15 studies involving 575 participants, testing Rhodiola's impact on physical and mental performance. They found evidence of improved physical endurance and reduced mental fatigue, but emphasized the need for higher-quality research to confirm these benefits.

In 2015, a small study funded by the National Center for Complementary and Integrative Health (NCCIH) compared Rhodiola to sertraline (Zoloft) and a placebo in people with mild to moderate depression. Rhodiola performed as well as sertraline in alleviating symptoms, with fewer side effects. Larger trials are needed to validate these findings on effectiveness and safety.
Overall, more robust, large-scale studies are essential. In the interim, consult reputable sources for deeper insights into Rhodiola's potential.
Key advice: Always inform your doctor about any supplements or integrative therapies. Share details on products, dosages, and quantities to ensure safe, coordinated care.
