White Mulberry Extract (Morus alba)

Also known as: Morus alba leaf extract, mulberry leaf extract, white mulberry leaf powder

C
Evidence

White mulberry leaf extract contains polyphenols and alkaloids that may help moderate blood sugar levels and support cardiometabolic health. Most evidence comes from in vitro and animal studies, with limited human clinical data.

Primary uses

  • Blood sugar management
  • Cardiometabolic support
  • Antioxidant support

How it works

  • α-glucosidase inhibition (delays carbohydrate absorption)
  • Antioxidant activity via polyphenols
  • May improve insulin sensitivity

Dosage

Typical range
500–2000 mg daily
Timing
With meals, particularly before carbohydrate-heavy meals
With food
Recommended; may be taken with food to enhance effect on glucose
Duration
Effects on glucose are typically assessed within 2–4 weeks; long-term safety data limited beyond 12 weeks
Special populations

Forms

  • Powder extract· 70/100
  • Leaf powder· 70/100
  • Capsules· 70/100

Safety

Common side effects

  • Mild GI upset
  • Constipation
  • Dizziness (rare, at high doses)

Contraindications

  • Concurrent use with diabetes medications without medical supervision (hypoglycemia risk)
  • Pregnancy and lactation (insufficient safety data)

Evidence notes

Several human studies show modest effects on postprandial glucose, but sample sizes are generally small and study quality is mixed. Stronger evidence exists for related compounds like mulberry leaf tea in Asian populations. More rigorous RCTs needed.

Grade C: Mostly observational or small trials; mechanism is plausible but unproven at scale.
