We cold-press the whole seed which means we don't extract every last drop of oil out of the seed through the expellers. Our expellers extract two products; Flax Seed Oil and Flax Seed Flake. The Flax Seed Flake is then milled down to a very fine powder to form the Flax Seed powder used in many of our powder supplement blends. This means there is a very low oil content, but overall the powders are very shelf stable.
