White mulberry leaf extract supplements are available in various forms, such as capsules, tablets, and teas. The key features of white mulberry leaf extract supplements include

 

 

Blood sugar-lowering effects: 

White mulberry leaf extract supplements may help reduce blood sugar levels by inhibiting the absorption of carbohydrates. The extract contains 1-deoxynojirimycin (DNJ), an alpha-glucosidase inhibitor. Alpha-glucosidase is an enzyme that breaks down carbohydrates into simple sugars, such as glucose, which are absorbed into the bloodstream. By inhibiting alpha-glucosidase activity, white mulberry leaf extract may slow down the absorption of carbohydrates, which can help lower blood sugar levels.

Studies have suggested that white mulberry leaf extract may effectively reduce blood sugar levels in people with type 2 diabetes. The extract has also been shown to lower hemoglobin A1c (HbA1c) levels, which is a measure of blood sugar control over some time.

Cholesterol-lowering effects: 

White mulberry leaf extract supplements may help control cholesterol levels by inhibiting the absorption of dietary fats. The extract contains compounds known as steroidal saponins, which have been shown to decrease the absorption of dietary fats by inhibiting the activity of pancreatic lipases. These enzymes are responsible for breaking down fats. By reducing the absorption of fats, white mulberry leaf extract may help lower cholesterol levels, particularly LDL (bad) cholesterol.

Several studies have suggested that white mulberry leaf extract may effectively reduce cholesterol levels, but more research is needed to confirm its effectiveness. The extract has been shown to lower cholesterol levels in animal and cell culture studies.

Antioxidant properties: 

White mulberry leaf extract supplements contain flavonoids and other beneficial compounds that may have antioxidant properties. Antioxidants help protect cells in the body from damage caused by harmful molecules known as free radicals.

Flavonoids are a type of antioxidant found in many plants, including white mulberry. These compounds have been shown to protect cells from damage by neutralizing free radicals and may also have anti-inflammatory properties. Moreover, white mulberry leaf extract also contains several other antioxidant compounds such as gallic acid, kaempferol, quercetin, and others.

Anti-inflammatory properties: 

White mulberry leaf extract supplements may have anti-inflammatory properties, which can help to reduce the production of inflammatory compounds in cells, such as prostaglandins and leukotrienes. Inflammation is a natural response to injury or infection, but chronic inflammation can contribute to the development of various diseases such as heart disease, cancer, and diabetes.

The flavonoids and other beneficial compounds found in white mulberry leaf extract have been shown to have anti-inflammatory properties. In some animal studies, it was also observed to reduce inflammation in several conditions, such as colitis, rheumatoid arthritis, and other models. However, more clinical research is needed to confirm the anti-inflammatory properties of white mulberry leaf extract in humans.

White mulberry leaf extract also contains compounds known as steroidal saponins, which have been shown to decrease the absorption of dietary fats by inhibiting the activity of pancreatic lipases. These enzymes are responsible for breaking down fats. By reducing the absorption of fats, white mulberry leaf extract may help lower calorie intake and aid weight loss.

The extract contains 1-deoxynojirimycin (DNJ), an alpha-glucosidase inhibitor. Alpha-glucosidase is an enzyme that breaks down carbohydrates into simple sugars, such as glucose, which are absorbed into the bloodstream.
