Ginkgo Biloba

• Cognitive Support & Mental Clarity
• Circulation & Vascular Support
• Antioxidant Protection
• Stress & Age‑Related Wellness (Emerging Research)

Ginkgo is one of the world’s oldest living tree species — often called a “living fossil” — traditionally used to support circulation, cognitive clarity, and overall vitality. Modern research highlights ginkgo’s flavonoids and terpene trilactones, which contribute to its antioxidant and neuroprotective reputation. Most consumer products are made from the leaf extract, not the seed (which contains compounds requiring caution).

4) Stress & Age‑Related Wellness (Emerging Research)
Some studies explore ginkgo’s potential role in healthy aging, cellular protection, and resilience to stress. These findings are early-stage and should not be interpreted as disease‑treatment claims.
