Not to be confused with the lecithin we already make in our bodies, sunflower lecithin is made by – you guessed it – sunflowers!1
Sunflower lecithin, and other plant sources of lecithin, were originally viewed as mere by-products of the oil refining process, e.g. removing it from sunflower oil better to give it better stability, so we could cook with it.2
Nowadays, sunflower lecithin has been upgraded in the eyes of many and is used as an emollient in medicines, cosmetics, dietary supplements and food.3
What is sunflower lecithin used for?
You have most likely already eaten some foods containing sunflower lecithin as it’s a popular additive in chocolate, mayonnaise, margarine, bakery and instant products as an emulsifier for its unique fat composition.4
Its job is to suspend oils and fats and keep them away from other substances so they can’t mix.
It also occurs naturally in some foods, including5:
- Nuts
- Wholegrains
- Egg yolks
- Soya beans
- Sunflowers
You will also see it on the ingredients of some beauty products, like moisturisers and serums, as emollients can help draw moisture into the skin and make it feel nice and smooth.
There are other claimed health benefits of sunflower lecithin, but we’ll get onto those below!
Is there a difference between sunflower lecithin and lecithin?
Not much of one, no. Whether it is made in the human body, in animals and animal products, or found in plants (mainly their seeds), lecithin is simply a mixture of fatty acids called glycerophospholipids, including:
- Phosphatidic acid
- Phosphatidylserine
- Phosphatidylinositol
- Phosphatidylethanolamine
Soy lecithin is the most popular plant source of the compound, but some people are allergic to soy or are concerned about its GMO status and so opt for sunflower lecithin.

The top 7 sunflower lecithin benefits
-
Helps lower cholesterol
Research suggests that lecithin could lower levels of LDL (bad) cholesterol, while raising levels of HDL (good cholesterol). One study in 2009 found that participants who took 500mg of lecithin daily lowered their cholesterol by 56% in just 2 months.1
-
May support breast-feeding
According to anecdotal evidence, there are some potential sunflower lecithin breastfeeding benefits.
Lecithin is already found in human breast milk. Some women like to take lecithin supplements to help prevent blocked milk ducts and reduce the thickness of their breast milk, so they can have an easier time breastfeeding their children. However, there are no current studies that can prove that it works in this way.2
However, some breastfeeding experts, like the British organisation NCT, do suggest that taking a lecithin supplement may help to get rid of milk blisters that form on blocked milk ducts of breastfeeding mothers.3
-
Could help reduce feelings of tiredness and weakness
According to the EU’s Committee on Herbal Medicinal products, lecithin can help to reduce feelings of weakness and tiredness.4
Similarly, a study in 2018 in Nutritional Journal found that women who were going through the menopause experienced reduced tiredness and increased energy when taking a high daily dose (1200mg) of lecithin.5
-
May provide support for your cardiovascular system
When you consume lecithin, your body breaks it down into a vitamin-like essential nutrient called choline.
Some research suggests that choline can help support cardiovascular health by altering lipid (fat) profiles, helping to maintain normal blood pressure and reducing levels of plasma homocysteine.6
-
May support cognitive function in elderly adults
Although research is limited, the way that choline reacts in brain seems to help support the structure of neurons and promote cognitive function in older people.7
-
Can help moisturise skin
When applied directly onto the skin in beauty and skincare products, lecithin has been seen to soothe and soften the skin.
This may be because of its emollient properties, which typically help to create a barrier on the skin to seal moisture in, making it potentially beneficial for dry and ageing skin.8
-
Can be safer than other lecithin
Sunflower allergies are quite rare, whereas soy allergies are more common, making sunflower lecithin potentially less risky than soy lecithin.
Does sunflower lecithin have lectins?
No, sunflower lecithin does not contain lectin.
