By Constipation is a common digestive issue that can affect anyone, regardless of age or lifestyle. It is often defined as having fewer than three bowel movements per week or experiencing hard, difficult-to-pass stools. While occasional constipation is normal, chronic constipation can negatively impact quality of life and may point to dietary or lifestyle imbalances. One food group often questioned in this context is milk and milk alternatives. Many people report that dairy can worsen constipation, which has led to growing curiosity about whether plant-based milks, like almond milk, might have the same effect.
Almond milk is one of the most popular non-dairy alternatives worldwide. It is lactose-free, widely available, and often fortified with vitamins and minerals to mimic the nutritional profile of cow’s milk. But as more people make the switch, a question arises: Does almond milk cause constipation, or can it actually help? In this article, we’ll explore research, health benefits, risks, and practical advice to help you understand the effects of almond milk on your digestion.
What is Almond Milk?
Before discussing Does almond milk cause constipation, let’s understand what it is in the first place. Almond milk is a plant-based beverage made by blending almonds with water and then straining the mixture to remove solid particles. Unlike dairy milk, it is naturally lactose-free, making it a popular choice for people who are lactose intolerant or allergic to cow’s milk proteins. Unsweetened almond milk is low in calories and typically fortified with nutrients such as calcium, vitamin D, and vitamin B12, providing health benefits similar to those of dairy milk.
In recent years, almond milk has become one of the most widely consumed plant-based milks globally. According to data from the Plant Based Foods Association, sales of plant-based milk alternatives in the United States grew by 33% between 2019 and 2022, with almond milk accounting for the largest share of this growth. (Source: Plant-Based Foods Association, 2023).
Its rise in popularity is driven by health-conscious consumers seeking dairy-free options, as well as by people following vegan or plant-based diets. Moreover, its mild flavor, creamy texture, and adaptability in coffee, smoothies, and cooking have made it a mainstream alternative to traditional milk.
What is Constipation?
Constipation is a common digestive condition characterized by infrequent bowel movements, difficulty passing stools, or a sensation of incomplete evacuation. Medically, it is often defined as having fewer than three bowel movements per week. (Source: Mayo Clinic) Symptoms may include hard or lumpy stools, abdominal discomfort, bloating, and straining during bowel movements.
The impact of constipation on daily life can be significant. Studies estimate that up to 16% of adults worldwide experience chronic constipation, with prevalence increasing among older adults and women (Source: National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK)). Beyond physical discomfort, persistent constipation can affect sleep, work productivity, and overall quality of life. In some cases, it may also signal underlying health conditions, such as irritable bowel syndrome (IBS) or metabolic disorders. Because of this, understanding potential dietary triggers and remedies—including plant-based milks like almond milk—is important for managing digestive health.
Milk and Constipation: The Debate
Traditional cow’s milk has long been associated with digestive discomfort in sensitive individuals. For people who are lactose intolerant, dairy can cause bloating, gas, and sometimes constipation. A study published in the New England Journal of Medicine found that lactose intolerance is especially common among Asian, African, and Native American populations, affecting digestion when dairy is consumed in excess.
This background is important because many people who switch from dairy to almond milk are specifically looking for digestive relief. Since almond milk is lactose-free, it is generally considered a better choice for those who experience constipation due to dairy intolerance. However, confusion remains, partly because almond milk is often fortified with calcium and thickeners, which some claim may worsen constipation. To clarify, we need to dive into the research.
What Research Says About Almond Milk and Digestion
- Whole Almonds and Gut Health
Almonds, the primary ingredient in almond milk, are widely recognized for their digestive benefits. They contain fiber, magnesium, and prebiotics, all of which support healthy bowel function. A randomized controlled trial published in The American Journal of Clinical Nutrition showed that almond consumption did not slow gut transit time or worsen constipation but instead improved the growth of beneficial gut bacteria and increased short-chain fatty acid (SCFA) production, such as butyrate, which is linked to better colon health (NCBI).
- Almond Milk’s Composition
Unlike whole almonds, almond milk is mostly water (about 98%) and contains little actual almond content. This means that while it delivers hydration,a key factor in preventing constipation, it does not contain as much fiber as eating whole almonds. Its gut benefits largely depend on whether the product is unsweetened, fortified, and free from problematic additives.
- Additives and Processing
Some brands of almond milk include additives like carrageenan or thickeners to improve texture. While generally recognized as safe, carrageenan has been linked in some studies to gastrointestinal irritation, which could worsen constipation in sensitive individuals (Verywell Health). Therefore, choosing almond milk with minimal ingredients is crucial for digestive health.
Does Almond Milk Cause Constipation: Myths vs. Facts
- Myth: Almond milk causes constipation.
Fact: There is no direct evidence linking almond milk to constipation. Its high water content may actually help ease digestion. Problems usually arise from additives or overconsumption. - Myth: Almond milk is high in fiber, so it prevents constipation.
Fact: Almond milk itself contains very little fiber, so its role in digestion is not as strong as whole almonds. Its main benefit is hydration. - Myth: All almond milk products are equally healthy.
Fact: Unsweetened almond milk with no carrageenan or artificial thickeners is the best choice. Sweetened or highly processed versions may negatively affect gut health.
Benefits of Almond Milk for Digestion
- Hydration and Regularity
Because almond milk is mostly water, it can support hydration, one of the most overlooked contributors to constipation relief. Dehydration makes stool harder and more difficult to pass, and adding almond milk to your diet can contribute to daily fluid intake (Allrecipes). - Gentle on Sensitive Stomachs
Almond milk is lactose-free and considered low-FODMAP, meaning it does not ferment in the gut in the same way as dairy or certain plant foods. This makes it suitable for people with IBS (Irritable Bowel Syndrome) or those prone to bloating and discomfort. (Verywell Health) - Nutrient Contribution
Almond milk is often fortified with calcium, vitamin D, and vitamin E. Vitamin E acts as an antioxidant that supports overall gut health, while magnesium, a mineral naturally found in almonds, helps relax muscles in the digestive tract, making bowel movements easier.
Does Almond Milk Cause Constipation: Risks and Considerations
- Additives and Preservatives
As mentioned, carrageenan and other thickeners may irritate the gut in certain individuals. If you notice constipation or bloating after drinking almond milk, check the ingredient list first. - Overconsumption
While almond milk is safe, drinking more than 2–3 cups per day, especially fortified varieties, may lead to excess intake of calcium carbonate or sodium, which could contribute to constipation in sensitive individuals (MedicineNet). - Lack of Protein and Fiber
Unlike cow’s milk, almond milk contains very little protein and fiber. If used as your only milk substitute, it should be paired with a balanced diet rich in whole foods to avoid nutritional gaps.
Finding the Right Balance
If you’re considering almond milk for constipation relief, balance is key:
- Stick to unsweetened varieties with minimal additives.
- Limit intake to 1–2 cups daily unless otherwise advised by a healthcare professional.
- Combine with fiber-rich foods such as vegetables, legumes, and whole grains.
- Ensure proper hydration and physical activity, which play equally important roles in digestion.

Conclusion
So, does almond milk cause constipation? The evidence suggests that almond milk is unlikely to be a direct cause of constipation. In fact, its hydration potential, lactose-free nature, and gentle digestibility make it a suitable choice for most people seeking a plant-based milk alternative.
However, results vary from person to person. For some, especially those sensitive to additives like carrageenan, almond milk could contribute to digestive discomfort. The key lies in choosing high-quality, unsweetened brands, moderating your intake, and maintaining an overall balanced diet.
If constipation persists despite making dietary changes, it is always wise to consult a healthcare provider. Remember, there is no one-size-fits-all approach to gut health, but small adjustments like switching to almond milk can make a positive difference when tailored to your body’s needs.
