Catuaba bark extract concentrates the bark of Brazilian trees from the Erythroxylum or Anemopaegma genus. Unlike whole bark powder, the extract standardizes active compounds for more consistent effects and possibly better absorption.
Traditional Brazilian medicine uses catuaba to boost energy, mental alertness, and overall vitality. Some people also take it for mood or libido. These uses rest on folk tradition, not robust clinical studies.
The extract may have stimulating effects, so most people take it in the morning or early afternoon to avoid sleep trouble. Standardized extracts are common, but the right dose varies by product.
Side effects can include restlessness, insomnia, or digestive upset. Its safety during pregnancy, breastfeeding, or with health conditions is not well studied.
