Flaxseed Water Calories: How Much Is in a Glass?

A 250 ml serving of flaxseed water contains approximately 27–53 kcal when you eat the 5–10 g of flaxseed in it. Use the ai nutrition analyzer to estimate a serving based on how much flaxseed you consume, whether you strain it and whether you add other caloric ingredients. For more on the drink, see the flaxseed water guide.

How many calories are in flaxseed water?

The calories depend mainly on how much flaxseed ends up in your glass and whether you consume it. Water itself has no calories, while flaxseed contains 534 kcal per 100 g, according to USDA FoodData Central.

If you consume all the flaxseed used in a 250 ml serving, the following estimates apply:

These are estimates for the flaxseed, not laboratory measurements of a prepared drink. They assume plain water and no other caloric ingredients. Additions such as sugar, honey or juice increase the total; use their package information to account for the amount added.

If you strain out the flaxseed, do not count all the seed’s calories as calories in the liquid. Some material can remain in the water, including the gel that forms around flaxseed, but the calorie content of that liquid is not established by the USDA data for whole flaxseed. Without a measurement of the finished drink, a precise number would be guesswork.

For a practical estimate, weigh the flaxseed you add and decide whether you will consume it all. If some is discarded, the whole-seed calculation is an upper estimate for that batch, not an exact value for the strained portion.

What are the nutrition facts per 250 ml?

The table below uses the USDA FoodData Central entry “Seeds, flaxseed” to calculate the contribution from 10 g of flaxseed. The example assumes you consume all 10 g, with enough plain water to make a 250 ml serving. The USDA entry describes the seed, not a tested flaxseed water product.

The nutrient values come from the flaxseed alone; mineral content in water can vary. If you use twice as much flaxseed and consume it all, the seed’s calculated nutrient contribution doubles. If you consume half as much, it halves.

Flaxseed supplies fat, fiber and protein. A 2019 review of dietary flaxseed discusses these components in flaxseed, but it does not establish how much transfers into a particular glass of strained flaxseed water. The table should not be used as a nutrition label for strained flaxseed water.

How does flaxseed water compare with juice and soda?

The useful comparison is the same serving volume, not just the same glass or bottle. Plain water has 0 kcal, while the example flaxseed water with 10 g of flaxseed consumed has approximately 53 kcal per 250 ml.

Juice and regular soda often contain more calories than plain water, but their labels vary by product. Check the package and adjust its serving to 250 ml: for example, halve the listed calories if they are given per 500 ml. Compare that number with a flaxseed water estimate that matches what you actually drink and eat.

A strained glass may have fewer calories than the whole-seed example, but its exact value remains unknown. Adding a sweetener or another caloric ingredient can also change the comparison, so include those additions rather than assuming every flaxseed water preparation has the same calorie count.
