Salacia 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 Salacia interacts with.

Salacia might increase the risk of hypoglycemia when taken with antidiabetes drugs.
Clinical research suggests that salacia might lower blood glucose levels.
Severity Moderate Likelihood Probable Evidence D

Interaction has not been documented in well-controlled studies, however, the interaction has been demonstrated in some small human studies or in controlled animal studies in conjunction with multiple case reports..

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

Here's the thing to keep in mind with Starlix (nateglinide): it already works hard to lower your blood sugar by nudging your pancreas to release insulin, especially right after meals. Salacia comes at the same goal from a different angle, slowing how fast carbs from your meal turn into sugar in your gut. Stack the two together and they can pull blood sugar down further than either one alone.

That means a higher chance of low blood sugar (hypoglycemia), which can show up as shakiness, sweating, dizziness, hunger, or feeling foggy. This concern is based on how both products work rather than hard studies pairing them, so it's a reasonable caution, not a guarantee. Please don't change anything on your own. Let your pharmacist or doctor know before adding salacia so they can help you watch your numbers.

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…”

About Salacia

What is Salacia?

Salacia
  • Blood sugar control
  • Type 2 diabetes support
  • Weight management
  • Obesity
  • Traditional Ayurvedic remedy

Salacia is a plant used in Ayurvedic medicine, mostly studied for lowering blood sugar after meals. Some small human studies suggest it may modestly blunt blood sugar spikes, but the evidence is limited and far from conclusive. If you have diabetes or take other medicines, talk with your pharmacist or doctor before using it.
