What Are Glucerna Shakes?
Glucerna is a brand by Abbott Nutrition specifically formulated for people managing diabetes or prediabetes. The shakes are designed as meal replacements or snacks that produce a lower glycemic response compared to standard nutritional drinks like Ensure.
The core innovation is Glucerna's CARBSTEADY® blend — a mix of slowly digestible carbohydrates that helps blunt post-meal blood sugar spikes, a critical concern in diabetes management.

Who Should Use Glucerna?
Glucerna shakes are best suited for people with Type 2 diabetes who need convenient meal replacements, struggle with portion control, or require structured caloric intake. They are also appropriate for prediabetes management.
People with Type 1 diabetes must still count carbohydrates carefully and dose insulin accordingly — Glucerna does not eliminate the need for blood sugar monitoring.
Monitoring Your Response
Every individual responds differently to meal replacements. The most reliable way to assess if Glucerna works for you is to test your blood glucose 1–2 hours after consumption. Using a quality blood glucose meter or continuous glucose monitor (CGM) gives you real data on your personal response.
MDS Diabetes offers a wide range of blood glucose meters, CGM supplies, and diabetes management tools to help you track your response to nutritional choices accurately.
Expert Recommendation
Glucerna shakes are a reasonable short-term tool for blood sugar management and convenience, but should complement — not replace — a whole-food diabetes diet. Work with a registered dietitian to integrate them appropriately into your meal plan.
