Betalains are the natural pigments of beetroot, chard, prickly pear, and dragon fruit, studied for fighting oxidative damage and calming inflammation. The clearest signals are less exercise soreness and lower inflammation markers; blood pressure, cholesterol, and blood sugar effects are weaker. Safe overall, with harmless red urine the usual effect. Independent benefits remain unsettled. (Full Review)
| Marker | Target | Why |
|---|---|---|
| Blood pressure | ~110–120 / 70–75 mmHg | Tracks the main vascular outcome |
| hs-CRP | < 1.0 mg/L | Tracks the anti-inflammatory effect |
| LDL cholesterol | < 100 mg/dL | Tracks the lipid-related signal seen in small trials |
| Triglycerides | < 80 mg/dL | Tracks cardiometabolic response |
| Fasting glucose | 80–90 mg/dL | Tracks the glucose signal reported in small trials |
| Homocysteine | < 8 µmol/L | A coronary-heart-disease betalain trial reported reductions |
Cadence: Baseline, then ~4–8 weeks after starting, then every 6–12 months for sustained use; blood pressure checkable at home during the first 1–2 weeks if combining nitrate-containing products with medication
