Glucerna Review - Does This Diet Shake Actually Work? Are bad taste and negative feedback deal breakers?

Editor's Review: 3.3 / 5.0

08-05-2013-01-50-32_59856-GSS-Van-8oz-CanThere’s been plenty of gossip about Glucerna shakes, so we did one of our in-depth reviews, examining the side effects, ingredients, clinical research and level of customer service. We additionally spent a lot of time reading user comments and customer reviews that are posted online. At this point we summarized and compressed all of the facts and feedback to give you the bottom line.

EDITOR'S TIP: Combine Glucerna with a proven fat burner such as Leptigen for better results.

What You Need To Know

Glucerna is a line of products specifically marketed at people with diabetes. These products include the following; Glucerna Shakes, Glucerna Advance Shakes, Glucerna Hunger Smart Shakes, and Glucerna Mini Snack Bars and Crispy Delight Bars. The purpose of these products is to help you manage blood sugar levels and watch your weight. These shakes and snacks assist by minimizing blood sugar spikes. The original Glucerna shake contains the following; 190 calories, 7 grams of fat, 5 milligrams of cholesterol, 210 milligrams of sodium, 10 grams of protein, 6 grams of sugar, 3 grams of fiber and 23 grams of carbohydrates. This shake also provides 27 vitamins and minerals.

Glucerna is made by Abbott Global, and has been available since at least 2007. This shake can be purchased online for $40 (24-pack) and both chocolate and vanilla flavors are offered. Since these shakes are prepackaged and ready-to-drink, they are easy to take anywhere, but read on…

Bad Taste!

According to our Research Editor, “We certainly noticed a lot of negative user reviews concerning the actual taste of Glucerna shakes. Unfortunately if a product tastes unpleasant, people are unlikely to use it regularly. This makes it ineffective.”

One customer complained, “This stuff is nasty! Like it was ran through a hot garden hose nasty. I will be throwing the rest of this stuff out.”

Another user said, “I hated the taste! Not good at all for me.” Yet another person stated, “Awful tasting!”

Negative Customer Feedback

If you take a look at dealer websites such as Amazon, you will find numerous user complaints regarding Glucerna shakes. One dieter stated, “I tried the vanilla and chocolate and both gave me diarrhea. The taste was tolerable, not wonderful. I wished it didn’t make me sick.”

“I tried one this morning. After about 20 minutes I felt nauseous and had a severe gastrointestinal reaction,” said another person.

The research we have done has proven that if there is some particular facet of a diet shake or weight loss system that is especially concerning or difficult (bad taste, very high cost, too many customer complaints) the probability of weight loss results for the long term is rather low. So, if Glucerna shakes do result in a lot of negative customer feedback, this could be a serious dilemma.

The Science

Fortunately there are some studies that support Glucerna products for regulating blood sugar levels and not causing blood sugar spikes. This makes these shakes okay for people with diabetes. On the other hand, we did not find clinical evidence that links Glucerna shakes to weight loss. At DietSpotlight, we prefer to see documented research that proves the diet product works for weight management.

The Bottom Line

We are glad to see that Glucerna shakes and snacks are suitable for people with diabetes. However, we do not recommend these products for other people who are trying to slim down and shed excess body fat. The truth is Glucerna is not specifically for weight reduction. Also, there are quite a few complaints concerning the taste of these shakes. Some users even complained about intestinal pains and diarrhea.

For dieters who wish to see more weight loss results, we encourage you to choose a diet product that contains clinically proven ingredients specifically for boosting metabolism and speeding up fat loss.

Among the top-rated products we’ve seen in 2015 is one called Leptigen. This supplement uses a blend of four important ingredients, which have been proven in published scientific studies to increase metabolism and encourage fat loss. Moreover, we can’t find any discussion of negative side effects and user comments posted online show people are seeing solid results.

Also, the makers of Leptigen are so confident in their product they’re offering a Special Trial Offer, which is a good sign.

Glucerna SR is a diet supplement aimed at diabetes sufferers made by Abbott Labs. Glucerna SR comes in several forms including shakes, powders, bars, and chews. These are sold as meal replacements that manage glucose levels and improve lipid levels. Glucerna cannot be purchased directly from the manufacturer's website but appears to be widely available in pharmacies and grocery stores. The website does offer a discount coupon to try the product. There does not appear to be any free samples or trial sizes so that consumers can try out the product first. The website is informative and easy to navigate. The company provides details of active ingredients in the Glucerna products and references them to clinical studies supporting their effectiveness. They also provide a full description of the purpose of each of the ingredients in the formulation. A full ingredient list is provided for each product along with the Nutrition Facts label. There is also a page for customer testimonials for all of the products.


According to the Glucerna website, some of the common active ingredients in the Glucerna products are: chromium picolinate, omega-3 fatty acids, sucromalt, DAG oil, phytosterols, whole grains, and Vitamins C & E.

Product Features

The main purpose of Glucerna products is to help those with diabetes eat healthy with better management of blood glucose levels than with regular snacks. A side benefit is that many physicians and nutritionists believe that if blood glucose levels are moderated, the body stores less fat. This feature of Glucerna may help in weight management in those with diabetes and even those without. The ingredients in the Glucerna products are similar to those in many nutritional supplements. The addition of Vitamins C & E provides anti-oxidants which can improve overall health by destroying the free radicals that can cause disease in the body. The whole grains ensure that the products contain fiber and they also regulate blood glucose.

Glucerna SR products are handy ways for those with diabetes to help manage their condition while providing healthy snack alternatives. Glucerna SR products may also help those trying to lose weight, but as the products are not specifically designed for that purpose, they may contain more than the recommended calories for weight loss. There are many weight loss aids on the market today that contain clinically proven ingredients like green tea extract and Citrimax. If weight loss is your primary goal, you may wish to research these products before trying Glucerna.
