Goji Berry Powder

Also known as: Lycium chinense, Wolfberry, Chinese wolfberry, Goji

C
Evidence

Goji berries are nutrient-dense dried fruits traditionally used in Chinese medicine, containing polysaccharides, carotenoids, and antioxidants. Limited clinical evidence exists for most marketed health claims, though observational studies suggest potential benefits for eye health and immune function.

Primary uses

  • Antioxidant support
  • Eye health
  • Immune system support
  • General wellness

How it works

  • Polysaccharide-mediated immune modulation
  • Carotenoid (zeaxanthin, lutein) antioxidant activity
  • Free radical scavenging via phenolic compounds

With food
No strict requirement; may enhance absorption if consumed with fat
Duration

Safety

Common side effects

  • Mild digestive upset
  • Allergic reactions (rare)
  • Potential stimulant effects in sensitive individuals

Contraindications

  • Concurrent use with warfarin or other anticoagulants (theoretical risk)
  • Nightshade sensitivity (goji is in Solanaceae family)
  • Pregnancy/nursing (insufficient safety data)

Evidence notes

Most claims lack robust RCT evidence. Traditional use and preliminary in vitro/animal studies support antioxidant potential, but human clinical trials are limited and often small. Eye health claims (zeaxanthin content) are plausible but not definitively proven in humans.

Grade C: Mostly observational or small trials; mechanism is plausible but unproven at scale.
