Lycium barbarum (goji berry extract, standardised)

Tier 2 — promising · Eye health · Antioxidant · TCM longevity

Goji berry has been used in TCM for thousands of years as a liver and kidney yin tonic for eye health and longevity. Contains zeaxanthin dipalmitate, a highly bioavailable carotenoid. The Li et al. 2021 RCT (Nutrients, 27 healthy adults, 28 g/day dried goji berries for 90 days) found significantly increased macular pigment optical density and skin carotenoid scores. Extract forms standardise the active carotenoids.

Dose: 15–30 g/day dried berries or 500–1,000 mg/day standardised extract; rich in zeaxanthin dipalmitate
