Mulberry leaves help manage high blood sugar, particularly after meals, by using compounds like 1-deoxynojirimycin (DNJ) to inhibit carbohydrate absorption. They are best used as tea (brewed 5–10 minutes) or taken as a 1,000 mg extract three times daily before meals.
How to Use Mulberry Leaves for High Blood Sugar
Mulberry Leaf Tea:
Preparation: Boil 1–2 tablespoons of dried leaves (or a few fresh leaves) in 2 cups of water, then simmer for 5–10 minutes.
Consumption: Drink it before meals to help reduce post-meal glucose spikes.
Mulberry Leaf Extract Capsules:
Studies suggest taking 1,000 mg of extract three times daily before meals to significantly lower blood sugar and insulin levels in those with type 2 diabetes.
Powdered Leaves:
Dried, powdered leaves can be added to smoothies, beverages, or taken with water.
Key Benefits and Considerations
Effectiveness:
Studies indicate that mulberry leaves help regulate post-meal blood sugar and improve long-term HbA1c levels, according to research shared on Vinmec.
Heart Health:
In addition to lowering blood sugar, they help improve lipid profiles, reducing triglycerides and LDL cholesterol.
Precautions:
Because they are highly effective, they may cause low blood sugar (hypoglycemia) if taken with traditional diabetes medications. Consult a doctor before starting to prevent potential interactions, advises Healthline.
Side Effects:
Some may experience mild gastrointestinal upset, such as gas or loose stools
