Linseed oil is a vegetal source of Omega 3. It is obtained from the flax plant (Linum usitatissimum) which contains high amounts of alpha-linoleic acid (ALA). ALA is a precursor of DHA (a type of Omega 3), which means humans have to convert ALA to DHA when attempting to obtain DHA from linseed).10
Why is plant derived Omega 3 less effective?
Research indicates that the conversion of plant-based Omega 3 (ALA) to DHA is unreliable, which suggests that getting Omega 3 from linseed is an inefficient way. Keep in mind that linseed needs to be ground up in order for the body to absorb the nutrients. This also explains why people obtain them from processed linseed oil.
