What it is

An adaptogen that helps your body handle physical and mental stress more efficiently. A 2025 review of 26 trials found it meaningfully improves aerobic capacity, time-to-exhaustion, and burnout symptoms. Benefits for acute stress can appear within days. Cycling prevents tolerance. Look for extracts standardised to at least 3% rosavins and 1% salidroside.

Take on an empty stomach in the morning. Avoid taking in the afternoon or evening — it is stimulating and can disrupt sleep. Take at least 30 min before breakfast.

Cycling
