Just like Taylor Swift during her Eras Tour, it seems like weight loss supplements are everywhere right now—and that includes insulin resistance supps.

Supplement companies market insulin resistance supplements to help lower your blood sugar, curb glucose spikes, support consistent energy levels, combat sugar cravings, and help you maintain a healthy weight. These supplements also claim to help lower the risk of developing insulin resistance, a condition where your body doesn’t respond the way it should to insulin. If left unchecked, insulin resistance can lead to weight gain, prediabetes, and type 2 diabetes, per the Centers for Disease Control and Prevention (CDC). And managing your blood glucose levels—and making sure they’re not too high—is also key for preventing any future diabetic issues, per the National Institutes of Health (NIH).

Here’s the thing: The FDA doesn’t approve dietary supplements or set categories within them, so it’s unclear what it even means to be an insulin resistance supplement. But brands are creating all sorts of supps within the category—Apothekary sells Sugar Kick drops, Nourished has PCOS Blood Sugar Balance supps, and Walmart has an entire online selection.
