Moringa (Moringa oleifera)

Tier 3 — weak evidence · Antioxidant · Glucose · Inflammation

A nutrient-dense plant with modest evidence for blood sugar reduction. A small number of RCTs in type 2 diabetes report reductions in fasting glucose, but trials are small, often open-label, and heterogeneous. Rich in antioxidants, vitamins, and minerals. NCCIH warns of limited safety data and possible interactions with thyroid and diabetes medications. Avoid seed and root extracts.

Dose: 1–2 g/day moringa leaf powder; avoid seed or root extracts (safety concerns)
