What Is Eleuthero Root (Eleutherococcus Senticosus)?
Eleuthero root (Eleutherococcus senticosus) is an adaptogen with a therapeutic history of use in many Asian countries such as China, Japan Korea, and also in Russia. Owing to its use in the latter country and its resemblance to ginseng, this supplement is also called Siberian ginseng. The root is traditionally utilized for anti-fatigue, pro-vitality, and longevity purposes. The main bioactive ingredients in the root are thought to be eleutheroside B and eleutheroside E, which are lignans. 
Eleuthero Root Benefits
Cognition and Mood
Eleuthero root may be capable of supplementing neurotransmitters in the body such as dopamine, serotonin, and noradrenaline. These neurotransmitters are partly responsible for promoting positive mood and cognitive capabilities.  Additionally, eleutheroside B has been implicated in supplementing neurite outgrowth in the brain.  Neurites are projections from the cell body of a neuron, and can be either an axon or a dendrite. These outgrowths help cells to transmit electrochemical signals; axons transmits signals away from the cell body while dendrites transmit signals into the cell body.
Eleuthero root can also be beneficial to enhancing your workout. One study found that Eleuthero supplementation improved both anaerobic performance and increased time to fatigue, with time to exhaustion increased by 16.3%.  Another study found that Eleuthero supplemented VO2 max levels . Your VO2 max is the maximum rate at which your body can consume oxygen. A higher VO2 max allows you to endure intense physical activities for longer periods of time. Supplementation with Eleuthero root can also maximize the effects on body composition from exercise.
