Astragalus is a traditional root tonic whose longevity use depends on the product. A purified extract lengthens white-cell chromosome end-caps without matching strength, walking, or inflammation gains. Add-on blood-sugar, kidney, and heart results are weaker. Oral use is mostly limited by nausea and stomach discomfort. Autoimmune disease, transplant drugs, pregnancy, allergy, and unsupervised injection sit on the avoid list. (Full Review)
| Marker | Target | Why |
|---|---|---|
| Fasting glucose | 70–85 mg/dL (3.9–4.7 mmol/L) | Tracks add-on glucose lowering |
| HbA1c | 4.8–5.3% | 90-day glucose exposure |
| hs-CRP | <0.7 mg/L | Inflammation; TA-65 secondary endpoint |
| eGFR | >90 mL/min/1.73 m² | Kidney filter function |
| Urine albumin–creatinine ratio | <10 mg/g | Early kidney protein leak |
| ALT | <25 U/L (women), <30 U/L (men) | Liver safety |
| Sitting and standing blood pressure | 110–120 / 70–80 mmHg | Additive pressure lowering |
| CBC with differential | Track change from own baseline | Lymphocyte remodeling; allergy signal |
Cadence: Baseline; repeat at 4–8 weeks, again at 3–6 months, then every 6–12 months if use continues. Matching drug-level or disease-activity checks on that cadence for lithium, insulin, or anti-rejection or immune-suppressing drugs
