Can I buy pre-ground flaxseed?

Yes, but it oxidizes (goes rancid) quickly due to the oils. It is best to buy whole seeds and grind/weigh them as needed, or store bought meal in the freezer.

Ground Flaxseed (Flax Meal)

Flaxseeds must be ground for your body to absorb their nutrients, but grinding changes their volume drastically. A cup of whole seeds does not equal a cup of ground meal. In vegan baking (flax eggs) or keto recipes, gram-level precision is vital for the binding chemistry to work.
