I found this interesting.  Back to cod liver oil supplements,
I guess, if one have a good working gallbladder.  Dr. Mercola's 
comments on this study appear afterwards.  I have not included 
them due to his advertising.  Original URL appears at the end.

Flaxseed Oil Does Not Increase Essential DHA in Breast Milk
 
Human breast milk is made up of fifty percent fat, a necessary component
to the growth of the newborn baby. The fat contains omega-3 and omega-6
essential fatty acids that facilitate the development of the brain,
retina and other organs. These fatty acids in human milk come from three
sources, body stores of fatty acids, synthesis of fatty acids by the
liver or breast tissue and the diet. 
Omega-3 fatty acids, including DHA, are particularly important because
they play a major role in the development of the newborn’s brain and
retina. The make up of fatty acid in breast milk is a reflection of the
type of dietary fat consumed by the mother both short and long term. For
example, women who took fish oil supplements, rich in DHA, for one to
four weeks were found to have increased levels of DHA in their breast
milk. Comparatively, women who eat fish on a regular basis have higher
quantities of DHA in breast milk than those who do not.
Flaxseed oil is a source of another fatty acid, ALA, the precursor fatty
acid in the synthetic steps that result in DHA, however studies have
shown that humans convert very little ALA from flax to EPA or DHA. One
study found that in the conversion of ALA to DHA, only .05 percent of
ALA was available for synthesis of DHA.
In one recent study, participants were given 15,000 mg flaxseed oil
daily for 12 weeks. Quantities of EPA, DPA, DHA or total omega-3 fatty
acids did not increase in plasma or erythrocytes. Moreover, after the
flaxseed oil supplementation was stopped, ALA concentrations in the
blood and breast milk had reverted to the original concentrations. 
Therefore, the study indicates that flaxseed oil is not an ideal source
of fatty acids for breast-feeding mothers.
