Total Terpene Lactones
Also known as: Ginkgo terpene lactones, Ginkgo diterpene lactones, TTLs, Total Terpene Lactones
Overview
Total Terpene Lactones (TTLs) are bioactive compounds primarily composed of bilobalide and ginkgolides A, B, C, and J, extracted from the leaves of *Ginkgo biloba*, a plant notable for its traditional medicinal uses. TTLs are recognized for their antioxidant and anti-inflammatory properties and are typically found in higher concentrations in standardized extracts used for enhancing cognitive function and promoting cardiovascular health. They hold potential as adjunctive treatments for conditions such as ischemic stroke. The body of research evaluating TTLs suggests a moderate level of evidence, with some significant clinical trials and meta-analyses available, although variability in study quality has been noted.
Benefits
The primary and most substantiated benefit of Total Terpene Lactones is their efficacy in the treatment of ischemic stroke, with meta-analyses indicating a relative risk of 1.18 (95% CI: 1.12, 1.24) for improved clinical outcomes compared to controls. Evidence supporting cognitive enhancement is noted, though results are mixed and less robust than for stroke. Secondary effects related to cardiovascular health and anti-inflammatory properties show promise but vary in strength across research studies. Clinical significance, especially regarding ischemic stroke outcomes, is clear, with most studies focusing on adults with cardiovascular or cognitive concerns. Typically, benefits manifest within weeks to months of consistent use.
How it works
Total Terpene Lactones exert their effects primarily through antioxidant and anti-inflammatory mechanisms. They modulate biological pathways associated with vascular health by enhancing blood flow and influencing platelet aggregation via interactions with platelet-activating factor (PAF) receptors. These actions primarily affect the cardiovascular and nervous systems, offering neuroprotective effects. TTLs are well-absorbed in standardized extract forms, though bioavailability may be impacted by various factors, including dietary components.
Side effects
Total Terpene Lactones are generally regarded as safe when taken as directed, with common side effects occurring in over 5% of users, including gastrointestinal issues and headache. Less common effects (1-5%) may include dizziness and allergic reactions, while severe allergic reactions occur infrequently (less than 1%). It's crucial to consider potential drug interactions, particularly with anticoagulants and antiplatelet medications, given the risk of bleeding. Contraindications include existing bleeding disorders and usage during pregnancy or breastfeeding. Caution is advised for individuals at higher risk of bleeding or currently on anticoagulant therapy.
Dosage
The recommended dosage for Total Terpene Lactones varies based on the preparation form, with a typical effective dose ranging from 120 to 240 mg of standardized extract that contains at least 24% flavone glycosides and 6% terpene lactones. While there is no universally established maximum safe dose, caution is warranted at higher dosages due to increased side effect risks. Consistent daily dosing, ideally with meals to enhance absorption, is encouraged, utilizing standardized extracts for reproducibility.
FAQs
Is it safe to take Total Terpene Lactones with other medications?
Yes, it's advisable to consult a healthcare provider before combining TTLs with medications, particularly anticoagulants due to potential interactions.
When is the best time to take Total Terpene Lactones?
For optimal effects, take TTLs consistently with meals to improve absorption.
What results can I expect from using Total Terpene Lactones?
Effects vary, but some users may experience improvements in cognitive function and cardiovascular health within weeks to months.
Are Total Terpene Lactones a cure for cognitive decline?
No, TTLs are not a cure-all; their benefits are condition-specific and should be part of a broader health strategy.
