Rhodiola rosea is one of the original and best-studied herbal adaptogens. Adaptogens help the body adapt to internal and external stressors, without stimulants or sedatives, by supporting normal physiological functions throughout the body.* Standardized higher than most, rhodiola rosea root extract provides 1 percent salidrosides and 5 percent rosavins. These important constituents ensure effectiveness and are only found in this tested species of rhodiola. Because adaptogens help reduce feelings of stress, many people feel increased energy and stamina while supplementing; for this reason, it’s best to take rhodiola rosea in the morning or mid-day.*
