Siberian Eleuthero (Eleutherococcus senticosus) root extract is a standardized adaptogen. The root yields a consistent dose of active compounds called eleutherosides, the form studied most often.
People use it to handle physical and mental stress, sustain steady energy, and reinforce immune defenses during demanding periods. Root extracts are more potent and reliable than leaf or stem preparations.
A typical dose is 300 to 400 mg of a standardized extract (for example, 0.8% eleutherosides) taken two to three times a day with meals. Taking it with food improves absorption and reduces stomach upset. Many people follow a cycle of six to eight weeks on, then a short break.
Eleuthero can interact with blood thinners (anticoagulants and antiplatelets), raising the risk of bleeding. It also can affect blood pressure and diabetes medications. Do not take it during pregnancy or while breastfeeding. Stop use at least two weeks before any surgery. Check with a healthcare professional if you have a medical condition or take other medicines.
