Lechner & Stoner, 2019 — Red Beetroot Review (PubMed/PMC)
Betalains exhibit strong antioxidant and free radical scavenging activity comparable to synthetic antioxidants. This comprehensive review found chemopreventive potential against various cancers, with betalain-rich extracts demonstrating protective effects in models of esophageal, lung, skin, and other cancers. Key mechanisms include reducing inflammation and oxidative stress linked to carcinogenesis.
Anticancer Properties of Red Beetroot Extract and Betanin on Colorectal Cancer Cell Lines
Saber et al., 2023 (PubMed/PMC)
Beetroot extract and purified betanin inhibited the growth of colorectal cancer cells (HCT116 and HT-29 lines) in a time- and dose-dependent manner. The compounds induced apoptosis by downregulating anti-apoptotic genes (such as Bcl-2) and modifying other key genes, while showing selective effects on cancer cells rather than healthy tissue.
Betalains: A Narrative Review on Pharmacological Properties
Martinez et al., 2024 (PubMed/PMC)
This review summarizes multiple studies showing betalains — especially betanin — induce apoptosis via mitochondrial pathways, caspase activation, and DNA fragmentation in various cancer cells including breast cancer and leukemia. Betavulgarin was found to inhibit proliferation, migration, and self-renewal of breast cancer stem cells. Effects were observed in cell lines and some animal models. Additional mechanisms cited include cell cycle arrest, ROS modulation in cancer cells, and epigenetic effects.
Betanin-Enriched Red Beetroot Extract Studies
Nowacki et al., 2015 & related research (PubMed/PMC)
Beet extracts rich in betanin showed cytotoxic activity against breast and prostate cancer cells, as well as preventive roles against tumor formation. Synergistic effects with chemotherapy drugs such as doxorubicin were observed in pancreatic, prostate, and breast cancer cell lines — potentially allowing lower chemotherapy doses. Additional in vitro findings include inhibition of tumor cell growth in stomach, breast, lung, colon, and leukemia cell lines; apoptosis induction in K562 leukemia cells; and reduced tumor angiogenesis in animal models.
Additional Findings Across Research
Other Supported Health Benefits
- Blood sugar balance — Betalains and fiber content support healthy glucose metabolism, with positive outcomes reported in individuals managing diabetes and insulin resistance.
- LDL cholesterol reduction — Soluble fiber in prickly pear has been shown to strongly reduce LDL (bad) cholesterol levels.
- Liver protection — Betalains provide significant protection from toxins that directly affect the liver, and may reduce the effects of alcohol-related oxidative stress.
- Anti-inflammatory action — Betalains help fight inflammation at the cellular level, with broader organ-protective properties noted across multiple studies.
