What is flaxseed water?

Flaxseed water is water steeped with flaxseed and then usually strained. The seeds release a gel-forming fiber into the water, giving it a thicker texture than plain water and a mild flavor.

It is one option in the broader category of spice and seed water. You can drink it chilled and decide whether to keep or discard the softened seeds.

What ingredients and ratio do you need?

For one serving, use 1 tablespoon of whole flaxseed per 1 cup of water:

10 g whole flaxseed (about 1 tablespoon, or 1/16 cup)
240 mL drinking water (1 US cup)

Use a clean jar or covered container and a fine-mesh strainer. Whole flaxseed is easier to strain than ground flaxseed, and the small batch lets you try the texture before making more.

How do you make flaxseed water?

Measure the flaxseed and water.
Combine them in a clean jar or other covered container.
Cover the container and refrigerate for 2 hours.
Stir the mixture, then pour it through a fine-mesh strainer into a glass if you prefer a smoother drink.
Serve chilled. Discard the strained seeds or eat them if you prefer a thicker drink.

Allow about 5 minutes for measuring, mixing and straining, in addition to the 2-hour refrigerated steep. The yield is approximate because some water and gel may remain with the seeds.

How long should flaxseed water steep?

Steep flaxseed water in the refrigerator for 2–4 hours. The 2-hour steep in this recipe is a starting point; a longer steep within that range can produce a thicker texture.

Stir before straining, since the gel can collect around the seeds. Strain when the texture suits you, then keep the finished drink refrigerated.

How should you store flaxseed water?

Keep flaxseed water in a clean, covered container in the refrigerator. Drink it within 24 hours for the best flavor, and discard it after 2–3 days. Do not leave it at room temperature for more than a few hours.

Discard it sooner if it becomes unusually cloudy or slimy, or develops a sour smell. Some gel-like thickening is normal for flaxseed water; if you cannot tell whether a change is expected, discard the drink.

What variations can you make?

For a citrus variation, add a thin slice of lemon before steeping and strain it out by 4 hours to limit bitterness. For a different flavor, steep a small piece of fresh ginger with the flaxseed, then strain both out before serving.

These additions change the flavor, not the basic method. Keep the drink refrigerated while it steeps, including when you add fresh ingredients.

What are the benefits of flaxseed water?

Flaxseed water can help you stay hydrated. Whole flaxseed also contains fiber, but the amount that ends up in strained flaxseed water is not established; eating the seeds is different from discarding them. Read more about flaxseed water benefits.

There is no established evidence that flaxseed water causes weight loss; see flaxseed water for weight loss for more on that goal. Your liver and kidneys do most of your body's detoxification, while the lungs and gut help eliminate waste and sweat removes only trace amounts.

Who should avoid or be careful with flaxseed water?

Avoid flaxseed water if you are allergic to flaxseed. If you have trouble swallowing or a history of bowel obstruction, ask a clinician before consuming it, especially if you plan to eat the seeds.

Flaxseed may cause digestive discomfort, including bloating, in some people. If you take oral medication, ask a pharmacist or clinician about timing, particularly when eating the seeds; fiber can affect how some medicines are absorbed. See more on flaxseed water side effects.

Seek medical advice for persistent digestive symptoms. Get urgent help for severe abdominal pain, repeated vomiting, or difficulty breathing or swallowing.

Flaxseed water FAQs

Can you use golden flaxseed? Yes. Golden or brown whole flaxseed can be used in the same ratio; either will give the water a mild flavor and some gel-like texture.
