Kaempferol is a common plant antioxidant in leafy greens, brassicas, capers, and tea. People eating more of it tend to live longer with less heart disease and cancer, though this tracks with healthier diets overall. Lab and animal work is promising, but supplement benefits in people remain largely unproven and absorption is poor. (Full Review)
| Marker | Target | Why |
|---|---|---|
| hs-CRP | < 1.0 mg/L | Tracks systemic inflammation, the pathway kaempferol is proposed to act on |
| Fasting glucose | 70–90 mg/dL | Screens metabolic health given preclinical blood-sugar effects |
| HbA1c | < 5.4% | Reflects 3-month average blood sugar; context for metabolic claims |
| ALT / AST | ALT < 25 U/L (men < 30); AST < 25 U/L | Liver is the main site of metabolism; screens for hepatic stress with concentrated supplements |
| Lipid panel (LDL-C, HDL-C, triglycerides) | Triglycerides < 80 mg/dL; HDL-C > 50 mg/dL; LDL-C context-dependent | Context for cardiovascular benefit hypothesis |
| CBC with platelets | Platelets 150–400 ×10⁹/L | Relevant if combined with blood-thinning drugs given theoretical antiplatelet effect |
Cadence: Baseline, then re-check at 8–12 weeks after starting a concentrated supplement, then every 6–12 months
