Consumption of flaxseed is well-tolerated in adults. Its safety and efficacy during lactation are not well researched (1), but it is considered safe to have them in small quantities.

Can Flaxseed Increase Breast Milk Supply?

There is an anecdotal belief that omega-3 fatty acids and phytoestrogensiBioactive compounds found in plants that may either inhibit or carry out the functions of estrogen. found in flaxseed can increase breast milk supply. Although lactating mothers use flaxseed as lactogenic food, there is no clinical indication of its use to regulate (increase or decrease) breast milk production. However, their intake in moderate amounts, with a well-balanced diet, can provide some health benefits.

Possible Health Benefits Of Flaxseed When Breastfeeding

Here are some benefits of consuming flaxseeds.

  1. Supply of nutrients: One tablespoon (10g) of flaxseed seed provides 1.8g of protein. The seed also contains essential micronutrients, such as magnesium, calcium, potassium, phosphorus, zinc, copper, and selenium (2).
  1. Source of DHA and EPA: Flaxseeds contain ALA (alpha-linolenic acid), one of the essential polyunsaturated fatty acids, which our body converts into DHA (docosahexaenoic acid) and EPA (eicosapentaenoic acid). Nursing mothers and their breastfed infants need essential fatty acids to perform various body functions important for growth, development, and sustainment (3).
  1. Essential fiber: The non-absorbable fiber found in flaxseeds helps keep constipation away. The fiber acts as a prebiotic for gut bacteria, boosts intestinal health, and in the long run, helps in weight management, too (4).
  1. Antioxidant effects: Flaxseeds are a good source of secoisolariciresinol diglucoside (SDG) and lignans that have potential antioxidant effects (5). Antioxidants are essential to combat oxidative damage that occurs due to free radicals.
  1. Anti-inflammatory properties: Research shows that flaxseed products, such as flaxseed oil, have anti-inflammatory, antipyretic, and analgesic properties (6) (7). Its topical use as a poultice to relieve inflammation and soreness in conditions like osteoarthritisiA form of arthritis that only impacts the joints causing inflammation and pain. is also documented (1) (8).

  1. Overall health benefits: Regular consumption of flaxseed with a well-balanced diet may help control blood sugar level, improve cholesterol levels, lower blood pressure, and improve heart health (9) (10) (11). Most of these flaxseed benefits are due to the presence of omega-3 fatty acids, insoluble fiber, and bioactive plant compounds, like lignans.

Besides these benefits, flaxseeds may help in treating health issues, such as bladder inflammation, vaginitis, and gastritis (12).

Precautions To Take While Consuming Flaxseed

Flaxseed should be consumed in moderation and with plenty of water as it could worsen constipation. Follow these precautions to avoid any possible side effects of the dietary intake of flaxseed (12).

  • Flaxseed is not a common allergenic food, yet some allergic reactions to flaxseed and flaxseed oil have been documented. Check for possible reactions if you are planning to include it in any form for the first time.

  • Avoid using flaxseed immediately after taking medicine, as it can delay the absorption time for certain medications.
  • Breastfeeding mothers with any bleeding disorders or those on blood thinners should avoid flaxseed as it might slow blood clotting.
  • Flaxseed contains phytic acid, an anti-nutrient that may reduce the absorption of micronutrients such as zinc and iron (13) (14). Therefore, excess intake of flaxseed must be avoided.
  • Lactating mothers on medications for diabetes and blood pressure (high or low) should consult a doctor before starting the consumption of flaxseeds as they are known to have anti-diabetic and hypotensive effects.
  • Avoid consuming partially defatted flaxseed meal as it might increase triglyceride levels in individuals suffering from high triglyceride levels.
  • Those with a history of thyroid problems must consult a doctor before ingesting ground flaxseed, flaxseed oil, and supplements (15).
