There’s something strangely comforting about a chilled bottle of Ensure. For many, it’s the go-to shake when meals become a chore, when illness steals appetite, or when the body simply needs a quick shot of nutrition.
But there’s a question whispered in hospitals, care homes, and kitchen counters alike: Can Ensure cause constipation?
Let’s unravel this, with science, a bit of storytelling, and a touch of human common sense.
What Exactly Is Ensure?
Ensure is a nutritional supplement drink made by Abbott Nutrition. It’s designed to provide calories, protein, vitamins, and minerals in one convenient bottle.
It’s often used by people who struggle to eat enough food, the elderly, recovering patients, or those seeking weight gain.
You’ll find variants like Ensure Original, Ensure Plus, Ensure High Protein, and even Ensure Max Protein.
Each bottle usually delivers around:
-
9–30 grams of protein (depending on the version)
-
220–350 calories
-
A mix of vitamins and minerals
-
Some sugar and fiber
Sounds balanced, right?
Yet, behind the smooth vanilla or chocolate taste, some users notice a rather uncomfortable side effect, constipation.
Does Protein Make You Constipated?
Let’s start there.
In theory, protein itself doesn’t directly cause constipation.
However, when you consume a high protein diet, especially with insufficient fiber, your digestive system can slow down.
Here’s why:
Protein-heavy diets often replace fiber-rich foods like fruits, vegetables, and whole grains. Without enough fiber, the intestines lack the “bulk” needed to move stool easily.
So, yes, while protein doesn’t cause constipation, a high-protein diet can lead to it indirectly.
It’s not the protein, it’s the imbalance.
And since Ensure High Protein or Ensure Max Protein shakes pack significant protein but relatively little fiber, they can contribute to slower digestion if not balanced with other foods.
Can Ensure Cause Constipation?
The answer depends on the person, and the type of Ensure consumed.
Some people tolerate Ensure beautifully. Others, especially those with sensitive digestion or low daily fiber intake, may experience constipation, bloating, or even mild stomach discomfort.
Possible Reasons Include:
-
Low Fiber Content:
Most Ensure formulas have little or no fiber. The bowels depend on fiber to keep things moving. -
High Protein Load:
As mentioned, high protein diets (and shakes) can slow transit time if not balanced. -
Sugar and Fat Mix:
Some Ensure versions contain added sugars and fats, which may slightly alter gut motility in sensitive individuals. -
Reduced Water Intake:
If you’re drinking Ensure instead of eating whole foods, you may also be drinking less water. Dehydration is a major cause of constipation.
In short: Ensure doesn’t directly cause constipation, but it can contribute if fiber or hydration are lacking.
Does Protein Powder Cause Constipation Too?
A fair question.
Like Ensure, protein powders can cause constipation if they crowd out fiber.
Most protein powders, whey, casein, or plant-based, have little or no fiber.
Some also contain artificial sweeteners like sucralose or sugar alcohols that can irritate the gut or slow digestion.
If you experience bloating or constipation from protein shakes, consider adding:
-
Ground flaxseed or chia seeds (for fiber)
-
More fruits and vegetables
-
Extra water intake
Your digestive system loves balance, not overload.
Can You Drink Ensure While Pregnant?
Pregnancy is a time when nutrition matters more than ever. Many expectant mothers wonder if Ensure is safe to drink during pregnancy, especially when appetite dips or morning sickness hits.
The good news?
Ensure is generally safe for most pregnant women, as long as it’s used as a supplement, not a full meal replacement.
However, if constipation is already an issue (and it often is during pregnancy), choose Ensure versions with added fiber or balance it with high-fiber foods like oats, berries, and vegetables.
Always check with your doctor before adding any supplement, especially if you’re managing conditions like gestational diabetes or high blood pressure.
High Protein Diet Constipation: The Common Thread
Constipation is a quiet side effect of many modern diets, from keto to low-carb to high-protein plans.
Why? Because when people focus on protein, they often forget about fiber.
Fiber adds weight and softness to stool. Protein, though essential for muscle repair and energy, doesn’t.
To fix this, balance is everything. For every protein shake or meal, aim to add a fiber source, a handful of nuts, a piece of fruit, or some leafy greens.
Also, drink plenty of water. The intestines need moisture to move stool smoothly. Without it, digestion slows down like a traffic jam.
Ensure or Boost, Which Is Better for Digestion?
Ah, the classic rivalry: Ensure vs Boost.
Both are nutritional drinks packed with vitamins, minerals, and protein. But which one’s easier on digestion?
Here’s a quick comparison:
| Feature | Ensure | Boost |
|---|---|---|
| Protein Content | 9–30g depending on type | 10–20g depending on type |
| Fiber | Some versions low in fiber | Boost High Protein often includes fiber |
| Sugar Content | Moderate to high | Slightly lower in some formulas |
| Digestibility | Creamy, may feel heavy for some | Often lighter, but still varies by person |
| Best For | Weight gain, recovery, added calories | Balanced nutrition, lighter digestion |
So, Boost may edge out Ensure for those prone to constipation, especially with its fiber-enriched versions.
But again, what works best depends on your body, taste preference, and tolerance.
How to Prevent Constipation from Ensure
Here’s how to keep your digestion on track:
-
Stay hydrated — drink 6–8 glasses of water daily.
-
Add fiber — fruits, oats, or psyllium husk help balance Ensure’s smooth texture.
-
Stay active — movement stimulates the intestines naturally.
-
Use Ensure in moderation — as a supplement, not your main diet.
-
Try different formulas — some Ensure products have fiber or prebiotics.
Final Thoughts
So, can Ensure cause constipation?
Not directly, but under the wrong conditions, yes, it can contribute.
Constipation from Ensure is less about the drink itself and more about what’s missing around it: fiber, hydration, and variety.
Think of Ensure as a helper, not a substitute. It supports recovery, boosts nutrition, and keeps you strong, but your body still craves the colors, textures, and fibers of real food.
Feed your body balance, and it will reward you with comfort, inside and out.
FAQs
1. Does protein make you constipated?
Not on its own. But high-protein diets with little fiber can slow digestion and cause constipation.

Yes, Ensure is generally safe in pregnancy when used as a supplement. Always consult your healthcare provider first.
3. Does protein powder cause constipation?
It can, especially if you don’t consume enough fiber and water.
4. Is a high-protein diet linked to constipation?
Yes, because it often lacks fiber-rich foods that keep digestion smooth.
5. Ensure or Boost — which is better?
Both are good, but Boost may be gentler for those prone to constipation, thanks to its fiber options.
