Black Mulberry and Liraglutide Recombinant

Here is the interaction we found between these two, with the evidence behind it.

Moderate

ANTIDIABETES DRUGS

Why this applies to Liraglutide Recombinant

Liraglutide Recombinant falls under ANTIDIABETES DRUGS — the group Black Mulberry interacts with.

Theoretically, black mulberry leaf might increase the risk of hypoglycemia when taken with antidiabetes drugs.
One small clinical study shows that black mulberry leaf extract has hypoglycemic effects. This is supported by in vitro research which also suggests that constituents in black mulberry twigs and leaves might have hypoglycemic effects.
Severity Moderate Likelihood Possible Evidence D

Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists.

Dr. Brian Staiger, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the simple version: liraglutide (Saxenda or Victoza) already lowers your blood sugar, and black mulberry leaf may nudge it down a little further. Mulberry leaf contains a compound (called DNJ) that can slow how your body absorbs sugar from food. So when you stack the two together, the worry is that your blood sugar could dip too low, what we call hypoglycemia. That can show up as shakiness, sweating, a racing heart, dizziness, confusion, or feeling unusually hungry.

Keep in mind this is a theoretical concern based mostly on early lab work and one small study, not strong proof. Eating mulberries as a fruit is very unlikely to matter. Concentrated leaf extracts are where I'd be more cautious. Please check with your pharmacist or doctor before adding one, and don't change your liraglutide on your own.

From our pharmacist’s overview on the Liraglutide Recombinant page

“If you take liraglutide (Saxenda), handle this page with real care, because all 239 ingredients on it act on the same thing the drug does, your blood sugar. The one major entry, Siberian cocklebur, has caused severe hypoglycemia, dangerously low blood sugar, in people and should never be combined with a glucose-lowering medicine.”
