Flaxseeds: omega-3 ALA, fibre and allies of motherhood

graines de lin
Natural source of plant-based ALA omega-3

Flaxseed is one of the richest plant-based sources of alpha-linolenic acid, an essential omega-3 fatty acid and precursor to EPA and DHA. A valuable addition to support daily intake of healthy fats, particularly during pregnancy and breastfeeding when requirements increase.

Gentle support for digestion and bowel regularity

The nutritional richness of flaxseeds in soluble and insoluble fibre supports digestion, may help relieve constipation and provides comfort to the body in the post-partum period, a time when returning to normal bowel function can take time.

Comprehensive profile for skin and new mothers

beyond omega-3s, organic flaxseeds provide plant proteins, lignans, polyphenols with antioxidant action, minerals and vitamin E for the skin. A daily tablespoon fits easily into a new mother's dietary routine.

Origin and description

Flax (Linum usitatissimum) is a herbaceous plant of the Linaceae family, cultivated for more than 5,000 years for its textile fibres and for its seeds, which have remarkable nutritional properties.

Flaxseed comes in two main colours, with very similar profiles:

Brown flax

  • Flavour: more rustic, slightly pronounced
  • Appearance: dark brown
  • Omega-3 ALA: high (≈ 50%)
  • Lignans: very rich
  • Typical use: savoury recipes, breads

Golden flax

  • Flavour: milder, neutral
  • Appearance: light golden
  • Omega-3 ALA: slightly higher (≈ 55%)
  • Lignans: very rich
  • Typical use: yoghurts, smoothies, gentle recipes

Both contain a rare combination of nutrients: between 50 and 60% alpha-linolenic acid, an essential omega-3, alongside lignans, soluble and insoluble fibre, plant proteins, vitamin E and minerals such as magnesium and manganese. This richness makes them a valuable food to support maternal health during pregnancy, the postpartum period and breastfeeding. 

In their natural form, flaxseeds can be used whole or ground on yoghurts, salads and bowls, mixed into bread, pancake or galette batters, or steeped as a mucilage to replace eggs in vegan recipes. Cold-pressed flaxseed oil is another concentrated source of omega-3 ALA. Their nutritional cousins, chia seeds and hemp seeds, share similar omega-3 profiles. Stored in a cool place, they retain their freshness and nutritional value.

As a food supplement and functional snack, flaxseeds are available ground, as cold-pressed oil, as mucilage or incorporated into recipes. Choosing organic seeds, rich in lignans and kept refrigerated, helps preserve the integrity of omega-3s that are sensitive to oxidation. This is the approach taken by Jolly Mama in its maternity snacks such as Cho-Chocolat or Milk Cookies, where brown flaxseed is combined with other actives targeted at breastfeeding support, as well as in Tomato Croq, a savoury granola compatible with pregnancy and breastfeeding. To explore long-chain omega-3 intake, the Jolly Mama DHA range offers complementary direct sources. The quality criteria to look for are organic origin, freshness and traceability.

Why are flaxseeds your maternity allies?

  • Natural source of ALA omega-3

    The high alpha-linolenic acid content of flaxseed contributes to meeting daily essential omega-3 requirements.

  • Digestive and bowel support

    Soluble and insoluble fibre support digestion, relieve constipation and promote regular bowel movements in the post-partum period.

  • Satiety and nutritional balance

    Rich in fibre and protein, flaxseeds help prolong satiety between meals without feeling heavy.

  • Cardiovascular support

    Several clinical studies suggest that regular consumption may contribute to cardiovascular comfort and support of the body.

  • Vitamin E, lignans and skin support

    Vitamin E and lignans contribute to protecting cells from oxidative stress and to supporting the skin on a daily basis.

How does it work? (The science bit)

Flaxseeds work through a combination of active compounds that act in synergy within the body. The alpha-linolenic acid they contain in large quantities is an essential omega-3, meaning the body cannot produce it and it must therefore be obtained through diet. Once ingested, ALA is absorbed in the intestine and partially converted into EPA and DHA, long-chain omega-3s involved in cardiovascular health and nervous system development. This conversion remains limited, which is why direct sources of DHA, such as microalgae, remain of interest alongside flaxseeds during pregnancy and breastfeeding.

The soluble and insoluble fibre in flaxseeds forms a mucilage in the intestine that slows sugar absorption, supports digestion and nourishes the gut microbiome. Lignans, polyphenols for which flax is one of the richest dietary sources, are converted by intestinal bacteria into enterolactone and enterodiol, two compounds with antioxidant activity. Several meta-analyses have highlighted a favourable effect of regular flaxseed consumption on blood pressure and certain cardiometabolic markers. Vitamin E also contributes to supporting the skin and the body. In products such as Cho-Chocolat, Milk Cookies and Tomato Croq by Jolly Mama, organic brown flax is combined with actives chosen to support maternity.

Key takeaway: 1 tablespoon of ground flaxseeds per day is enough to provide a valuable dose of omega-3 ALA, fibre and lignans. Grind them just before use, keep the ground seeds for a maximum of 5 to 7 days in the fridge, and pair them with good hydration for digestive comfort.

Your questions, our answers.

Our practical routine: grind a portion for the week only, store whole seeds away from light and moisture, and keep the ground flaxseed in the fridge in an airtight jar for a maximum of 5 to 7 days. One tablespoon a day of this organic seed is more than enough to supplement your omega-3 and fibre intake: sprinkle it on a yogurt, in a porridge, a soup or a salad. Flaxseed oil is also an excellent source, to be used cold only.

Vegan mucilage tip: one tablespoon of ground flaxseed mixed with three tablespoons of water, left to swell for 5 minutes, replaces an egg in your recipes (pancakes, cookies, cakes). Ideal for plant-based recipes and compatible with a diet during pregnancy and breastfeeding.

Whole or ground flaxseeds, in the usual quantities incorporated into the diet, remain compatible with pregnancy. They provide ALA omega-3 and fibre that is valuable for digestion. Caution is advised with highly concentrated lignan supplements or oils at high doses, due to their potential phyto-oestrogenic activity. For snacks containing organic flaxseed, such as Tomato Croq, the quantities are perfectly suited to daily use.

Yes, flaxseed is generally very well tolerated. A gradual introduction is recommended to allow the digestive system to adjust to the additional fibre intake: at first, some people may experience mild bloating. Remember to drink plenty of water to support healthy digestion. Oils and ground seeds oxidise quickly when exposed to air: opt for fresh products, stored away from light.

Flaxseeds remain a safe food in usual quantities. If you are taking medication, particularly anticoagulants or hormonal treatments, or if you have a hormone-dependent condition, seek advice from a healthcare professional before consuming them very regularly, due to their phyto-oestrogenic lignans. 

Flaxseed is among the foods traditionally associated with the postpartum period and breastfeeding, particularly for its nutritional richness in ALA omega-3, a precursor of DHA which is important for infant brain development. They integrate easily into a routine of lactation support, in synergy with other active ingredients such as fenugreek or fennel. No direct galactagogue effect has been demonstrated, but their overall contribution is valuable.

Yes, flaxseed is an excellent ally during the post-partum period: its fibre supports digestion and bowel transit, which can slow down after giving birth; its ALA omega-3s contribute to maternal recovery; and vitamin E supports the skin. They fit naturally into a post-partum support routine, whether as seeds, oil, or functional snacks.
