Your dietitian can help you determine how to best incorporate Glucerna into your diabetes meal plan.

Why is Glucerna a good snack replacement?

Glucerna contains slow-release (low glycaemic index) carbohydrates, together with other nutrients including 28 essential vitamins and minerals, making it a great snack option for people trying to manage their blood glucose as well as meet their nutritional requirements.1,2 It is also quick to prepare and therefore has the added benefit of convenience.

What is the glycaemic index of Glucerna?

Glucerna has a low Glycaemic Index (GI); the powder (mixed with water) has a GI of 35 (Vanilla) and 29 (Chocolate), and the 220 mL Ready-to-Drink (liquid) Glucerna has a GI of 27.3-5

What are low-glycaemic carbohydrates?

Low-glycaemic carbohydrates (those with a low glycaemic index) are processed more slowly by our digestive system, and therefore cause a lower and slower rise in blood glucose.6

Glucerna Powder contains: Modified maltodextrin, sucromalt, maltitol, fructose, fructo-oligosaccharides, isomaltulose and oat fibre.1

Together, this combination of carbohydrates produces a lower blood glucose response compared with that of higher-glycaemic carbohydrates.2 Visit our science behind Glucerna page to learn more about how Glucerna can help manage your blood glucose levels.

Will Glucerna help me manage my weight?

Glucerna has been clinically shown to to help achieve (4 – 6%) weight loss in 6 months when used as part of a diabetes management plan.*7

Your dietitian can help you determine a diet plan that can help you safely and effectively manage your weight.

*As part of a lifestyle intervention. A weight loss of 4 – 6% of initial body weight was observed in overweight/obese diabetes patients receiving structured lifestyle intervention with Glucerna.

Have any scientific studies been done to support Glucerna’s claims?

Yes, Glucerna has been studied in more than 50 clinical studies and has over 30 years of scientific evidence.1

Will I be hungry again soon after drinking a Glucerna health shake?

Glucerna has a low glycaemic index (GI); the powder (mixed with water) has a GI of 35 (Vanilla) and 29 (Chocolate), and the 220 mL Ready-to-Drink (liquid) Glucerna has a GI of 27.3–5 This is because the carbohydrates in Glucerna are digested more slowly than refined carbohydrate foods, helping to keep you feeling fuller for longer.1,3–6

Is Glucerna a good choice for low blood glucose (hypoglycaemia)?

For people with diabetes, Glucerna products should not be used to treat hypoglycaemia, insulin shock, or insulin reaction. The carbohydrates in Glucerna are not absorbed quickly enough to restore blood glucose to a target level fast enough. Talk to your healthcare professional about appropriate treatment options for low blood glucose episodes.

Can Glucerna be used by people without diabetes?

It is safe for someone without diabetes to consume Glucerna. However, Abbott Nutrition has many other options, such as Ensure®, for people without diabetes to integrate into their meal plans.

Glucerna health shakes are specially designed for people with diabetes. Glucerna products are intended to be used under medical supervision to support the dietary management of diabetes.

Are Glucerna products appropriate for people with type 1 diabetes?

Glucerna products are appropriate for people with type 1 diabetes. However, it is important to monitor your blood glucose regularly to see how Glucerna affects it, as well as your insulin needs.

As always, we encourage you to speak with your healthcare professional before making any changes to your diabetes management plan.

Can Glucerna products be used during pregnancy for women with gestational diabetes?

Nursing and pregnant women should consult their healthcare professionals to see how Glucerna would best fit into their lifestyle.

In particular, be aware of the vitamin and mineral content of Glucerna when used together with other supplements (maternal vitamins and minerals) and with daily food intake, as it may exceed the recommended dietary intake (RDI) for some of the vitamins and minerals, such as vitamin A, folic acid and iron.

Consult your healthcare professional before starting Glucerna.
