🍃 Antioxidants & Phytochemicals

Guava juice is rich in cancer-fighting compounds, including:

• Vitamin C – powerful antioxidant that boosts immunity
• Lycopene – known for reducing prostate cancer risk
• Flavonoids – such as kaempferol and apigenin, which help prevent inflammation and oxidative stress
• Terpenes – natural plant compounds with anti-tumor effects

🔬 Lab & Animal Research

• In vitro (cell-based) studies: Guava extracts—especially from red-fleshed fruit and leaves—have been shown to:
  • Inhibit cancer cell growth
  • Promote apoptosis (cell death)
  • Reduce metastasis (spread of cancer)
• Animal studies: Mice given guava extracts had slower tumor growth in various types of cancers

👥 Human Studies

• Human evidence is very limited
• One small study in prostate cancer patients showed a reduction in tumor markers
• No large clinical trials confirm guava juice as a proven treatment
