Flax Milk
RegionalLimited commercial production
A seed-based plant beverage produced from flaxseed and water. Both laboratory-prepared and commercial flaxseed beverages exist, but their formulations are not standardized.
About Flax Milk
Flax milk is a plant-based beverage made from flaxseeds (Linum usitatissimum), also known as linseeds. Flax is one of the oldest cultivated plants in human history, grown for at least 10,000 years for its oil-rich seeds and strong bast fibres (used in linen production). Flaxseeds are nutritionally notable for their exceptionally high content of alpha-linolenic acid (ALA), a plant-based omega-3 fatty acid, as well as lignans (plant compounds with antioxidant properties) and soluble fibre.
Flax milk is produced by pressing flaxseeds to extract flaxseed oil, then blending this oil with water and other ingredients to create a stable emulsion. Unlike most nut or grain milks, flax milk sold commercially is typically made from cold-pressed flaxseed oil rather than whole ground seeds, as whole flaxseed milk can develop a thick, gelatinous texture due to the seeds' high mucilage content. Commercial flax milk is usually thin and neutral in flavour, with added pea protein for a protein boost, and fortified with calcium, vitamins D and B12, and other nutrients.
Flax milk is free of nuts, soy, gluten, and dairy, making it one of the most allergy-friendly plant milks available. It is suitable for people with multiple food allergies or intolerances. The ALA omega-3 content is its most distinctive nutritional feature compared to other plant milks, though the body's conversion of ALA to the longer-chain omega-3s EPA and DHA (found in oily fish) is limited.

Nutrition
Finished flax-milk nutrition varies by formulation, and many commercial products add other proteins or fortification. Raw flaxseed composition is background evidence, not a direct measure of a strained drink.

Flax milk is one of the few plant milks with a meaningful omega-3 ALA content. It is naturally low in protein (unfortified versions), though many commercial products add pea protein to improve their nutritional profile. It is free of dairy, nuts, soy, and gluten, making it suitable for people with multiple food allergies.
Common Uses
◌ Drinking◌ Coffee & tea◌ Smoothies◌ Cereal◌ Baking
Flax milk can be used like other plant milks in coffee, tea, smoothies, and cereal. Its flavour is relatively neutral, making it versatile in cooking and baking. It froths reasonably well for coffee drinks. Its allergy-friendly profile makes it a useful option for households with multiple dietary restrictions where other plant milks may be unsuitable.
Interesting Facts
- Flaxseed must be ground to release its nutrients — whole flaxseeds pass through the digestive tract largely intact. Flax milk typically uses flaxseed oil rather than whole ground seeds.
- Flax is one of the oldest textile fibres — linen, made from flax stems, has been woven for at least 30,000 years, with fragments of dyed linen found in a prehistoric cave in Georgia.
- Ground flaxseeds mixed with water form a gel that acts as an egg replacer in vegan baking — known as a "flax egg," this mixture mimics the binding properties of egg yolk.
- Flax milk is one of the few plant milks completely free of the top eight food allergens (milk, eggs, fish, shellfish, tree nuts, peanuts, wheat, and soy), making it exceptionally allergy-friendly.
- Canada is the world's largest producer and exporter of flaxseed, accounting for approximately one-third of global production.
