Fisetin

Fisetin clears senescent cells (caspase-driven), boosts apoptosis (Bax/Bcl-2), inhibits PI3K/Akt/mTOR + NF-κB/STAT3/VEGF for anti-prolif/inflam/angio. Preclinical strong in breast/CRC/lung/prostate; pulsed 100–2000 mg safe but monitor CYP/GI—no human oncology trials yet.

Key Takeaway

Fights cancer by clearing “zombie” senescent cells and pushing tumor cells toward apoptosis while dialing down PI3K/Akt growth signals; evidence is mainly preclinical.

How it may work

Fisetin, a flavonoid found in strawberries and apples, acts as a senolytic agent by selectively inducing apoptosis in senescent cells through activation of caspases-8 and -9, clearing 'zombie' cells that promote tumor growth. It inhibits PI3K/Akt/mTOR signaling, reducing proliferation, and upregulates pro-apoptotic proteins like Bax while downregulating anti-apoptotic Bcl-2. Fisetin also suppresses NF-κB and STAT3 pathways, limiting inflammation-driven cancer progression, and inhibits angiogenesis via VEGF downregulation. Preclinical studies demonstrate efficacy in breast, colon, and lung cancer models.

Dose: as studied, not a recommendation

These are doses as studied or reported, never a recommendation. The right amount of Fisetin depends on you, your other medicines, and your situation; decide it with your oncology team and pharmacist, not from a web page.

Ranges seen in adjunct / practice use: 100–2000 mg (po) Dietary: 10–100 mg/day from food. Supplements: 100–500 mg/day continuous; senolytic protocols: 20 mg/kg (~1400 mg for 70 kg) for 2 days, repeated monthly. Preclinical HED from mouse (10–50 mg/kg) ~0.8–4 mg/kg (~56–280 mg daily); human trials explore 100–2000 mg pulsed., Pulsed for senolysis (e.g., 2 days on/month). Take with fat for absorption. Bioavailability moderate; piperine may enhance. Not Rx; monitor GI at high doses..
