Is Almond Milk Gluten-Free?

From The New Day Notebook · Facts last checked October 21, 2026 · General information, not medical advice

Yes, plain almond milk is naturally gluten-free. The main ingredient, almonds, does not contain any gluten. This makes it a popular plant-based milk alternative for people following a gluten-free diet.

While the basic ingredients are safe, some flavored varieties, sweetened versions, or special barista blends can contain added ingredients that introduce a risk of gluten. Reading the label is always the best way to ensure the almond milk you choose is suitable for your needs.

Almond milk and gluten at a glance

Why almond milk is naturally gluten-free

Almond milk in its simplest form is made from just two ingredients: almonds and water. Nuts are naturally gluten-free, so the foundation of this beverage does not contain gluten. The process typically involves soaking almonds, blending them with water, and then straining the mixture to create a smooth, milky liquid.

Because of this simple composition, plain, unsweetened almond milk is considered gluten-free. This applies whether you make it at home or buy it from a store. It is a reliable choice for those who need to avoid gluten for medical reasons, including individuals with celiac disease.

Where gluten can sneak in

Gluten can sometimes be found in almond milk products due to added ingredients used to create different flavors, textures, or shelf stability. The primary concern is with flavored versions and specialty blends, such as those formulated for coffee shops.

Some potential sources of gluten include:

• Flavorings: Certain natural or artificial flavors, particularly those mimicking baked goods like cookies or cake, can contain gluten derivatives.
• Thickeners: While most thickeners are gluten-free, some formulations might use gluten-containing ingredients to improve texture.
• Added Oats: Barista blends are sometimes formulated with oat milk to improve frothing. Oats are at high risk for cross-contact with gluten-containing grains during growing and processing, and only oats specifically labeled gluten-free are considered safe for a strict gluten-free diet.

Cross-contact can also occur in manufacturing facilities that process products containing wheat, barley, or rye. Choosing products with a gluten-free label provides an extra layer of assurance.

Shopping, cooking and eating out

When buying almond milk, always check the ingredient list. Look for a “gluten-free” label on the package. Under United States regulations, a product labeled gluten-free must contain fewer than 20 parts per million (ppm) of gluten.

If you enjoy coffee drinks at a cafe, it is wise to ask questions. Ask the staff if the almond milk they use is labeled gluten-free. Also be aware of potential cross-contact from shared equipment, like milk steaming wands that may have been used with oat milk that is not gluten-free.

In your own kitchen, using plain, unsweetened almond milk is a straightforward swap in most recipes, from smoothies to sauces. As with all foods, read labels carefully and store gluten-free products separately to maintain a safe kitchen environment.

When to loop in your doctor or dietitian

For people with celiac disease, a strict gluten-free diet is the only treatment. If you are experiencing symptoms or have questions about your dietary needs, talk to your doctor or a registered dietitian. Do not start a gluten-free diet before being tested for celiac disease, as the tests require gluten to be present in your system for an accurate result.

• If you think gluten is making you unwell, ask about celiac disease testing before cutting gluten out: testing needs gluten in the diet
• If you have celiac disease and still have symptoms on a gluten-free diet
• If you are unsure whether oats, wheat starch or a specific ingredient suits you
• For help planning a gluten-free diet that still meets your nutrition needs
