![]() ![]() No increase in breastmilk DHA was seen during the study. The ALA content of milk reached a peak of 7.5% of fatty acids at the end of 4 weeks of supplementation and returned to near baseline of 1.9% after as little as one week after supplementation was discontinued. The ALA and docosapentaenoic acid (DPA) content of breastmilk increased markedly and EPA increased slightly during supplementation. Samples were collected at baseline, after the 2-week washout, weekly during supplementation, and for 4 weeks afterward. Ten breastmilk samples were collected at about the midpoint of nursing. The flaxseed oil was given as 1 gram capsules (Spectrum Essentials Veg-Omega 3 Cold Pressed Organic Flax Oil Spectrum Naturals Inc., Petaluma, CA) in 3 divided doses. Seven nursing women who were 2 to 11 months postpartum were given 4 weeks of supplementation with 20 grams flaxseed oil (10.7 grams of alpha-linolenic acid) daily after a 2-week washout period. More detailed information about dietary supplements is available elsewhere on the LactMed Web site. Flaxseed (sometimes spelled flax seed) has fiber and healthy omega-3 fatty acids, but when eaten without drinking enough water, side effects like digestive problems may occur. Because of the above issues, clinical testing results on one product may not be applicable to other products. A manufacturer may contract with an independent organization to verify the quality of a product or its ingredients, but that does not certify the safety or effectiveness of a product. Dietary supplements may contain multiple ingredients, and differences are often found between labeled and actual ingredients or their amounts. Manufacturers are responsible to ensure the safety, but do not need to prove the safety and effectiveness of dietary supplements before they are marketed. Freezing milk at -20 degrees C and thawing more than once decreases linolenic acid concentration by an average of 63%.ĭietary supplements do not require extensive pre-marketing approval from the U.S. Heating breastmilk to 63.5 degrees C reduces the concentration of linolenic acid by about 22%. Flaxseed oil can be used during lactation, but is not effective in counteracting a low maternal DHA intake, as in vegetarian or vegan diets. Flaxseed used by the nursing mother as a laxative or topical poultice are not expected to adversely affect the breastfed infant. However, supplementation of infant formula with ALA appears to improve the infant's DHA status. Very limited data exist on the safety and efficacy of flaxseed oil in nursing mothers or infants. FLEEX SEED SKINFlaxseed is generally well tolerated in adults, with occasional allergic skin reactions occurring. Maternal intake of preformed DHA, primarily derived from seafood or other marine oils, is required to increase breastmilk DHA content. Flaxseed oil increases the ALA content of breastmilk, but does not increase the DHA content. Flaxseed oil contains alpha-linolenic acid (ALA), which is partially converted into the omega-3-fatty acids, docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) in the body. Flax ( Linum usitatissimum) seed provides a nonabsorbable fiber which has been used as a laxative and has also been used topically to treat various skin conditions. ![]()
