Rhodiola extract is a dietary supplement made from the root of the Rhodiola rosea plant, also known as golden root, Arctic root, or roseroot. This plant grows in cold, mountainous regions of Europe and Asia and has been used in traditional medicine for centuries.

Rhodiola extract is believed to have adaptogenic properties, meaning it can help the body adapt to stress and improve overall well-being. It is also thought to have antioxidant and anti-inflammatory effects.

There are several versions of Rhodiola extract available on the market, including standardized extracts and whole root extracts. Standardized extracts typically contain a specific amount of active compounds, such as rosavins and salidroside, while whole root extracts contain a wider range of compounds that may have additional health benefits.

The Latin name for Rhodiola rosea is also sometimes used to refer to the extract: Rhodiola rosea extract.

Some of the potential health benefits of Rhodiola extract include:

Improved mental performance and concentration

Reduced fatigue and stress

Improved mood and well-being

Enhanced exercise performance and recovery

Improved immune function

Reduced symptoms of depression and anxiety

Several studies have been conducted on the health benefits of Rhodiola extract. A systematic review and meta-analysis published in the journal Phytomedicine in 2016 found that Rhodiola extract can improve physical and mental performance and reduce mental fatigue in healthy individuals. Another review published in the journal Expert Opinion on Investigational Drugs in 2011 found that Rhodiola extract may be a useful treatment for mild to moderate depression.

The recommended dosage of Rhodiola extract can vary depending on the specific product and the desired effect. In general, doses of 200-600 mg per day of a standardized extract containing 3% rosavins and 1% salidroside are commonly used in clinical studies. It is always best to follow the dosage instructions provided by the manufacturer and consult with a healthcare provider before starting any new supplement regimen.
