How to Ground Flax Seed

Flax seed provides an abundance of nutritional benefits. It is high in fiber, which helps improve your digestive system. Flax seed is also full of alpha-linolenic acid, which is an omega-3 fatty acid that can help combat arthritis, inflammatory bowel disease and heart disease. The outside of a flax seed is very hard to crack -- it will likely pass undigested through your body if you eat it whole. Grinding flax seed first makes it easier to digest and ensures that you absorb all of the nutrients.

Step 1

Measure out the desired amount of seeds and pour them into a clean coffee grinder, blender or food processor.

Step 2

Turn the setting to the finest grind possible and close the lid. Turn the grinder on.

Step 3

Grind the flax seed for 10 to 15 seconds, or until the seeds have turned into a very fine, ground meal.

Step 4

Store the ground flax seed in an opaque, airtight container in the refrigerator for as long as 90 days if you don't use it immediately.


For best results, clean your grinder, blender or food processor thoroughly before and after you grind flax seed. Food flavors can easily cross over into the flax seed and ruin the taste of your recipe.


Consult your doctor before eating flax seed. Flax seed can interact with some medications, decreasing their effectiveness or resulting in uncomfortable gastrointestinal side effects like nausea and gas.
