HelloPharmacist Scorecard of White Mulberry Leaf by ProCaps Laboratories

Four independent checks of what is known — a summary of the available information, not a grade of the product itself.

Evidence for Intended Use
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed
Not assessable

The stated purpose hasn't been mapped to our evidence data yet.

Why this rating?

Formula

Standardized to 1-deoxynojirimycin

Andrew Lessman's White Mulberry Leaf offers a targeted extract of White Mulberry Leaf standardized to deliver a 5% extract of the natural iminosugar 1-deoxynojirimycin. As one of the oldest traditional Chinese remedies, it should come as no surprise that modern science would one day recognize the health benefits of White Mulberry Leaf. In Asia, its leaves have been prized for centuries for their health promoting properties. More recently, White Mulberry Leaf has received scientific recognition for its unique ability to support healthy blood sugar balance, as well as healthy glucose and insulin metabolism. These benefits result from its apparent ability to reduce breakdown and absorption of dietary sugars and carbohydrate. Clinical research attributes these benefits to White Mulberry Leaf's high levels of the iminosugar 1-deoxynojirimycin. In short, if the extract is not specifically standardized to deliver high levels of this naturally occurring iminosugar compound then there is no way to expect or insure any benefits.

Antidiabetes Drugs

Theoretically, white mulberry leaf might increase the risk of hypoglycemia when taken with antidiabetes drugs.
Clinical research shows that white mulberry leaf can lower blood glucose levels. Advise patients to monitor glucose levels closely.

Likelihood Possible Evidence D
Organic Cation Transporter 2 (Oct2) Substrates

Theoretically, white mulberry leaf might slow the elimination and increase the adverse effects of drugs which are OCT2 substrates.
Animal research shows that coadministration of white mulberry leaf extract with metformin, an OCT2 substrate, slows the renal elimination of metformin via inhibition of OCT2 activity. OCT2 is expressed in the kidneys and is responsible for transporting cationic drugs into tubular epithelial cells in order to be excreted in the urine.
