Rhodiola rosea Root Extract†
Rhodiola rosea has been categorized as an adaptogenic botanical due to its ability to increase resistance to a variety of stressors. Rhodiola has been studied extensively and is widely used in Eastern Europe and Asia to help support the nervous system, mood regulation, mental clarity, work performance and the sleep cycle. Within the central nervous system, Rhodiola has demonstrated an ability to preserve levels of neurotransmitters such as serotonin, dopamine and norepinephrine. In a randomized, double-blind, placebocontrolled study examining the effects of Rhodiola on fatigue and stress, 161 patients aged 19 to 21 years received Rhodiola twice daily resulting in a significant reduction in fatigue.  An additional study using Rhodiola extract in students showed significant improvements in mental performance, greater mood stability and improved sleep patterns. 
Eleuthero Root Extract†
Eleutherococcus senticosus has been identified as a strong adaptogenic botanical and is widely used in China to support general health, memory and endurance.  In addition to its ability to improve stress resilience and fight fatigue, Eleuthero has exhibited immune supporting effects.  In a double -blind study, 45 healthy volunteers received Eleuthero or placebo for 30 days. A cognitive challenge test was given to assess stress response, and heart rate. Unlike placebo, subjects receiving Eleuthero demonstrated a 40% reduction in heart rate in response to the stressor.  Eleuthero has also been shown to improve performance in runners. In a study on performance athletes, Eleuthero extract (2 or 4 mL) given 30 minutes prior to a race significantly reduced race time (48.7 minutes) compared to the control group (52.6 minutes). 
Schizandra Berry Extract†
Schizandra berry extract is an adaptogenic botanical that has been used for centuries in China and Russia to help support mental clarity, stress response and emotional wellness. In a double-blind, placebo-controlled study, athletes who were given an adaptogenic blend including Schizandra chinensis extract or placebo, had increased concentrations of nitric oxide, a molecule which causes the blood vessels to expand resulting in increased circulation, increased blood flow and nutrients throughout the body and healthy blood pressure.  The researchers concluded that Schizandra berry enhances physical performance in athletes.  Schizandra berry has also been shown to support learning and memory and may have a protective effect on brain health. 
Ashwagandha Root Extract
Ashwagandha’s strong adaptogenic properties provide an array of benefits for individuals that have compromised health due to extreme stress exposure. Ashwagandha’s benefits include improving stress resilience, supporting immune response, regulating the sleep cycle, supporting healthy thyroid function and protecting against exhaustion of the nervous system. Ashwagandha has also been shown to be beneficial in supporting proper mood regulation and restoring a sense of calmness under stress.
