Lychee 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 Lychee interacts with.

Theoretically, lychee seed might increase the risk of hypoglycemia when used with antidiabetes drugs.
Animal research suggests that an aqueous extract of lychee seed reduces fasting and 2-hour postprandial blood glucose and improves impaired glucose tolerance in rats with type 2 diabetes. Additionally, retrospective research in children has found an association between lychee consumption and increased odds of acute hypoglycemic encephalopathy.
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 works to bring your blood sugar down. Lychee seed extract, at least in animal studies, also seems to lower blood sugar. Put the two together and there's a theoretical chance your sugar could dip a little lower than expected, which we call hypoglycemia.

I want to be honest about the strength of this. It's based on lab and animal research, not solid human studies, so it's more of a 'keep an eye out' than a red alert. Enjoying fresh lychee fruit as a snack is very unlikely to cause trouble. Concentrated seed extracts are the bigger question mark. Watch for shakiness, sweating, dizziness, or sudden hunger, and check with your pharmacist or doctor before adding any lychee supplement.

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.”

About Lychee

What is Lychee?

  • General nutrition and antioxidant support
  • Digestive complaints (traditional use)
  • Cough and sore throat (traditional use)
  • Blood sugar support (preliminary)
  • Weight and metabolic support (preliminary)

Lychee is a sweet tropical fruit that is nutritious and a source of vitamin C and antioxidant plant compounds. While the fruit is a healthy food for most people, supplement-strength extracts have only limited research behind specific health claims, and eating large amounts of unripe lychee on an empty stomach has been linked to dangerous low blood sugar in undernourished children. Talk to your pharmacist or doctor before using lychee extracts for any health condition.
