What are terpene lactones?

Terpene lactones are bioactive compounds in Ginkgo biloba, mainly ginkgolides and bilobalide. They are studied for effects on circulation, platelet signaling, and nervous system support.

What are terpene lactones used for?

They are most often used as part of Ginkgo biloba extracts to support cognitive function and peripheral circulation. Potential benefits are generally discussed in the context of standardized Ginkgo supplements rather than isolated compounds.

How do terpene lactones work?

Ginkgolides can act as platelet-activating factor (PAF) antagonists, which may influence platelet signaling and blood flow. Bilobalide is also associated with neuroprotective and antioxidant-related effects.

What is a typical dosage for terpene lactones?

Common dosing for Ginkgo biloba extracts providing terpene lactones is often in the range of 120–240 mg per day, depending on the product and goal. Follow the specific supplement label and clinician guidance.

Are terpene lactones safe and who should avoid them?

Ginkgo products can increase bleeding risk in some people, especially when combined with anticoagulants or antiplatelet drugs. Pregnant or breastfeeding individuals and those with upcoming surgery should consult a clinician before use.
