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

Editor's Review: 3.3 / 5.0
Glucerna Review

Give me two minutes of your time and I’ll tell you whether Glucerna actually works. We did one of our deep reviews, examining the side effects, ingredients, clinical research and level of customer service. We additionally spent a lot of time reading user comments 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

To start, Glucerna is a line of products specifically marketed at people with diabetes. These products include shakes, bars and snacks. The purpose is to help you manage blood sugar levels and watch your weight. The original contains 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. It 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 and both chocolate and vanilla flavors are offered. Since these are prepackaged and ready-to-drink, they are easy to take anywhere, but read on…

Bad Taste – “Ewww?”

The first thing we noticed when reviewing dieter experiences with Glucerna ingredients is that they don’t exactly sit well in the mouth. According to our Research Editor, “We certainly noticed a lot of negative user reviews concerning the actual taste of the shakes. Unfortunately if a product is 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 – “No Support”

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 results for the long term is rather low. So, if these leave the dieter wanting for more, that could be a problem.

The Science – “Evidence?”

Fortunately there are some studies that support Glucerna products for regulating blood sugar levels, but this is not the same as promoting weight-loss.  At DietSpotlight, we prefer to see documented research that proves the formula works for weight management and when that’s not there we’re not sure if the dieter should be willing to stick around.

The Bottom Line – Does Glucerna Work?

So, what’s the real bottom line on this one? We are glad to see that Glucerna shakes and snacks are suitable for people with diabetes. However, we do not feel comfortable recommending these products for people who are trying to slim down and shed excess body fat. The truth is it is not specifically for weight reduction. Also, there are quite a few complaints concerning the taste. 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 that’s not associated with negative customer reviews.

Among the best products we’ve seen in 2016 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, we believe it’s with confidence that the company behind Leptigen is 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.

  • Readily available for purchase.
  • Contains some vitamins.


  • Pre-made food products are more expensive than homemade.
  • Not specifically targeted to weight management in diabetes sufferers.


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.

    Im type 2 and i drink the 8oz can. I dont mind the taste but i get severe, theres no waiting dirahhea. I mean no squeezing n pinching n running. Its straight get outta the way. .i need the bathroom. It happens 15 min to 30 min after i drink it. The belly pains are that leaving me thinking its a bad war in my belly. It does keep my snacking and appetite low n controlled. That alone has helped me not gain weight. This should come with a disclaimer saying only drink at home or on the pot in prep for the action your stomach will soon feel n wittness!

    Cameron (Editor)

    We have looked into this and we could not find research or evidence of this claim. Take the formula to your doctor just to be safe.

    I well know that not all products are good for all people. I can only say that I have absolutely no problems with Glucerna. It has a pleasant taste with no negative aftertaste. And it does not upset my stomach. I plan to purchase more Glucerna after my present supply runs out. To each his own.

    The only item I LOVE is the Hunger Smart Shakes. The other Glurcerna shakes are too thick and they coat your mouth. The Hunger Smart shakes are light yet filling. If I drink one before bed when I take my insulin I do not drop too low during the night. Unfortunately it is getting very difficult to find.

    I have diabetes type 2 and so far I only have take the pills but I found that it has suppressed my appetite to the point of being 160lbs before diagnosis to being 130lbs if that and I just want to put some of my weight back on and I was hoping glucerna can help me with that problem will it help?


    Stephen (Editor)

    Luckily, TeeTee, Glucerna is specially made for people with diabetes. However it doesn’t necessarily claim to cause weight gain, only to regulate blood sugar.

    do u have a lactose free drinks


    Arnold (Editor)

    Hey, Victoria! Because the main site only lists a few ingredients it’s difficult to say whether this product has lactose or if any others do or do not: chromium picolinate, omega-3 fatty acids, sucromalt, DAG oil, phytosterols, whole grains, and Vitamins C & E.

    Glucerna makes me very sick. After having only one this morning I suffered with the worst stomach pains I have ever had, followed by hours of intense diarrhea, and vomiting. It’s happened twice before. Never again for me. So grateful to be feeling better tonight.
