Sage extracts can lower blood glucose and blood lipids in people with diabetes or elevated lipids, but evidence for healthy adults is indirect. Menopausal hot flashes may improve, but combined results are not uniformly convincing. Short-term memory and attention findings are intriguing, although small studies and blends limit confidence. No human evidence shows longer life or slower biological aging. (Full Review)
| Marker | Target | Why |
|---|---|---|
| Fasting glucose | 70–90 mg/dL | Detects baseline status and excessive lowering |
| Glycated hemoglobin | 4.8–5.4% | Tracks approximately three-month glucose exposure |
| Fasting lipid panel | No sage-specific target; individualized cardiovascular targets | Tests the main metabolic claim |
| Alanine and aspartate aminotransferases | Stable within laboratory range and personal baseline | Screens liver change |
| Creatinine and estimated glomerular filtration rate | Stable versus baseline; estimated filtration generally ≥60 mL/min/1.73 m² | Screens kidney change |
Cadence: Tolerability and fasting glucose at 2 weeks; hot flashes or cognition at 4 weeks; metabolic, liver, and kidney markers at 8–12 weeks. Longer monitoring commonly uses 3–6-month intervals, although use beyond trial durations lacks controlled safety evidence.
