High Sugar Content in Many Varieties
One of the most frequently cited drawbacks of Ensure is the high sugar content found in many of its products, such as the Original shakes. For individuals with diabetes or those simply trying to manage their sugar intake, this can be a significant concern. The inclusion of corn maltodextrin and added sugars can cause blood sugar levels to spike, potentially reducing the effectiveness of diabetes medication and contributing to weight gain over time. Even for those without diabetes, excessive sugar consumption can lead to negative health outcomes and is often viewed as a trade-off for convenience. For example, an 8-ounce serving of some Ensure shakes may contain as much as 14 grams of added sugar. This sugar content is especially concerning when the product is used as a consistent meal replacement, as the total daily sugar intake can become quite high. While low-sugar options exist, not all products within the brand cater to this need, and consumers must read labels carefully.
Potential for Gastrointestinal Distress
Many individuals who consume Ensure report experiencing gastrointestinal (GI) side effects, particularly during the initial stages of use. These effects can include:
- Diarrhea
- Constipation
- Bloating and flatulence
- Nausea and vomiting
For some, these symptoms may subside as their body adjusts to the supplement. However, for others, particularly those with sensitive stomachs or pre-existing digestive conditions, these issues may persist. Allergens and irritants present in some formulations, such as milk proteins, soy, or corn, can also trigger stomach problems. This can make relying on Ensure for consistent nutrition a challenge for those with significant GI sensitivities.
Risk of Dangerous Medication Interactions
Another critical con is the potential for serious interactions with certain medications. Ensure and similar nutritional drinks often contain high levels of specific vitamins, which can interfere with prescription drugs. A key example is Vitamin K, which is present in many Ensure products at levels that exceed 20% of the Recommended Daily Intake. This can be particularly problematic for individuals taking blood thinners, such as Warfarin (Coumadin), as high doses of Vitamin K can decrease the drug's effectiveness and increase the risk of blood clots. Anyone on a complex medication regimen should always consult a doctor before incorporating Ensure into their diet.
Inferior Nutritional Profile Compared to Whole Foods
While Ensure is fortified with a wide array of vitamins and minerals, it cannot fully replicate the benefits of consuming whole, unprocessed foods. Nutritional drinks are a processed food category, and they lack the natural fiber, antioxidants, and diverse phytochemicals found in fruits, vegetables, and whole grains. These natural compounds work synergistically in the body to promote optimal health, an effect that is not fully captured by synthetic fortification. Relying on Ensure as a long-term meal replacement can lead to an inferior nutrient intake and a missed opportunity to get the full spectrum of health benefits that a varied, whole-food diet provides. As Harvard Health points out, for most healthy people, there is no evidence that these supplements improve health over getting nutrition from a regular diet.
Comparison Table: Ensure vs. Real Food
| Feature | Ensure | Whole Foods |
|---|---|---|
| Nutrient Diversity | Fortified with a specific list of vitamins and minerals. | Offers a wide and complex range of nutrients, including phytonutrients and antioxidants. |
| Fiber Content | Low in fiber, can lead to digestive issues. | High in natural dietary fiber, essential for digestion and gut health. |
| Sugar Content | Many varieties contain significant added sugars. | Natural sugars from fruits and other sources are often balanced with fiber. |
| Absorption | Synthetic vitamins may not be absorbed as efficiently. | Nutrients in their natural form are highly bioavailable. |
| Satiety | Less satisfying than solid food, may not provide the same fullness cues. | Chewing and fiber promote satiety and a feeling of fullness. |
| Cost | Can be more expensive than obtaining nutrients from whole foods over time. | Cost varies, but often more affordable long-term, especially when buying seasonal. |
Disappointing Taste and Texture
Some consumers report a synthetic, unpleasant taste or an unappealing texture when consuming Ensure. Reviews on retail sites mention a bitter aftertaste or inconsistencies in batches, with some finding the texture too thick or clumpy. While flavor is subjective, these accounts suggest that for some, the experience is not enjoyable, which can make consistent consumption difficult. This stands in contrast to the enjoyment and sensory satisfaction derived from eating varied whole foods. While mixing Ensure with other ingredients can improve palatability, it adds an extra step to a product promoted for its convenience.
Potential for Weight Gain and Nutrient Overload
For individuals whose primary goal is not weight gain, using certain Ensure products can lead to unintended weight gain due to the calorie-dense nature of some formulas, like Ensure Plus. Ensure was originally designed to provide supplementary nutrition to those who are underweight or malnourished. Over-consuming these calorie-rich shakes, especially on top of a regular diet, can lead to gaining unwanted weight. Additionally, the fortification level can lead to a potential nutrient overload for some individuals, especially seniors who might not need such high percentages of every vitamin and mineral.
Conclusion
While Ensure serves a valuable purpose for individuals with specific medical needs, the cons highlight that it is not a perfect solution for everyone. The high sugar content in many standard products, the risk of digestive issues, potential drug interactions, and inferior nutritional profile compared to whole foods are all significant considerations. For most healthy adults, a balanced diet of whole foods offers a superior and safer source of essential nutrients. Those with underlying health conditions or on certain medications should always consult with a healthcare professional or registered dietitian before making Ensure a regular part of their regimen. Understanding these downsides allows for a more informed decision about whether a convenient nutritional drink outweighs the drawbacks for your personal health situation.

Frequently Asked Questions
Is it bad to drink Ensure every day?
It may not be bad for individuals with specific medical needs or malnutrition, but for most healthy people, relying on Ensure daily can be detrimental. It can lead to an inferior nutritional intake compared to whole foods, potential weight gain due to high sugar, and digestive issues.
Does Ensure cause bloating?
Yes, some individuals experience bloating, flatulence, and other forms of gastrointestinal distress from drinking Ensure. This can be due to ingredients like corn maltodextrin, milk proteins, or soy, to which some people are sensitive.
Can Ensure make you gain weight?
