Sunflower Lecithin for Breastfeeding – What To Know

Check out these fun facts about sunflower lecithin and its benefits for breastfeeding mothers.

What Is Sunflower Lecithin?

Sunflower lecithin is a fat-like substance made from dehydrated sunflower seeds.

After dehydrating the seeds, the manufacturer will split them into solids, gum, and oil through a cold-press system. The gum is the lecithin.

Lecithin is used in processed foods as an emulsifier, which helps holds together two liquids without them separating.

Breastfeeding mothers prefer sunflower lecithin over other types of lecithin because of its all-natural ingredients and status as a non-GMO product.

Sunflower Lecithin Benefits for Lactation

Besides being an all-natural, non-GMO product, sunflower lecithin prevents clogged milk ducts and any unpleasant symptoms that come with them.

As a result of the change in your milk, you can benefit from the following:

  • Pain-free breastfeeding sessions
  • A calm, content baby during feedings
  • Less chance of developing mastitis, an infection from clogged milk ducts
  • Less chance of breast abscess, which can only be cleared by a medical professional

Is Sunflower Lecithin Bad for You?

No, sunflower lecithin isn’t bad for you, but like any supplement, it’s possible to consume too much of it.

If you have more than 5,000 milligrams of sunflower lecithin in one day, you may suffer from digestive issues, such as nausea, abdominal pain, bloating, and diarrhea.

Compared to other types of lecithin, sunflower lecithin is typically considered healthier.

Does Sunflower Lecithin Decrease Milk Supply?

No, sunflower lecithin doesn’t decrease milk supply. It makes your breast milk smoother and less sticky to help prevent clogged milk ducts.

As an emulsifier, sunflower lecithin breaks up the fat globules in breast milk to allow it to come out of the milk ducts more efficiently.

Sunflower Lecithin Breastfeeding Side Effects

Sunflower lecithin has very few side effects when used to help with breastfeeding. The Food and Drug Administration (FDA) claims that lecithin is safe for consumption.

If you take too much of it, you may experience stomach upset and diarrhea. Some babies and mothers are also allergic to lecithin, but since sunflower isn’t a common allergy, it’s usually safer to consume than soy lecithin.

Sunflower Lecithin Effects on Baby

There are no known side effects in breastfed babies whose mothers take sunflower lecithin. Since this substance reduces the stickiness of breast milk, it may make the milk easier for your baby to consume.

If you have any concerns, you should consult your doctor or your baby’s pediatrician before taking sunflower lecithin.

Sunflower Lecithin Breastfeeding Dose

The Canadian Breastfeeding Foundation suggests a sunflower lecithin breastfeeding dose of 1,200mg four times daily.

This amount is safe for consumption and effective in reducing the stickiness of a mother’s breast milk. For specific dosages, refer to the specific product’s nutrition information on the bottle.

Soy Lecithin vs. Sunflower Lecithin Breastfeeding

As the name suggests, soy lecithin is extracted from soybeans. It tends to be more economical than sunflower lecithin, but it’s not as healthy.

Sunflower lecithin doesn’t require a solvent during the extraction process, so the ingredients are more natural than soy lecithin.

Instead of using a solvent, manufacturers use a cold-press system, similar to how extra virgin olive oil is created. Sunflower is also a healthy alternative for babies who are allergic to soy.

  • The area around the lump you feel may be irritated and red.

Causes of Clogged Milk Ducts

Clogged milk ducts are caused by:

  • Missing feedings.
  • Making your breastfeeding sessions too short.
  • Spacing breastfeeding sessions too far apart.

How To Prevent Clogged Milk Ducts

  • Keep your baby on a consistent breastfeeding schedule, whether on demand or by the clock.
  • Wear loose clothing instead of tight-fitting bras, shirts, or dresses. You may even want to go up a cup size in bras.
  • Try different breastfeeding positions during a nursing session so your baby empties all areas of your breasts.
  • Stay hydrated to keep up your milk supply and flow.
  • When you want to wean your baby, do it slowly and gradually instead of all at once.
