Terminalia Bellirica and Nateglinide

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

Moderate

ANTIDIABETES DRUGS

Why this applies to Nateglinide

Nateglinide falls under ANTIDIABETES DRUGS — the group Terminalia Bellirica interacts with.

Theoretically, concomitant use of Terminalia bellirica with antidiabetes drugs could affect blood sugar control and increase the risk of hypoglycemia.
Animal research suggests that Terminalia bellirica fruit extract, alone or in combination with Terminalia chebula and Indian gooseberry, has hypoglycemic effects. This activity has not been shown in humans.
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 explains PharmD, Clinical Pharmacist

Here's the gist for Starlix (nateglinide): this pill prompts your pancreas to release insulin around mealtimes to lower your blood sugar. Terminalia bellirica (Bibhitaki) may have its own mild blood-sugar-lowering effect, at least in animal studies. So the worry is simple addition, two things nudging your sugar down at once, which could tip you into low blood sugar (hypoglycemia). Watch for shakiness, sweating, dizziness, a fast heartbeat, confusion, or sudden hunger.

I want to be honest about the strength here: this is theoretical, based on lab and animal research, not proven in people. It's not a reason to panic. Still, if you'd like to try this supplement, check your readings closely and talk with your pharmacist or doctor first.

From our pharmacist’s overview on the Nateglinide page

“People who take nateglinide (Starlix) with meals for type 2 diabetes are often drawn to supplements marketed for blood sugar, and that overlap is why these 290 interactions warrant real caution. Some 239 of the ingredients affect blood sugar on their own, most pushing it lower, so stacking them on nateglinide raises the odds of hypogly…”
