Soy lecithin is one of the most ubiquitous additives in our food supply. It’s used primarily as an emulsifier, and you can find it in everything from salad dressing to tea bags. Paleo dieters avoid the brunt of it by eliminating most processed foods, but it almost always pops up in chocolate (everyone’s favorite honorary Paleo food) and often appears in supplements.

I recommend avoiding soy as a general rule, but consuming small amounts of soy lecithin as an additive is very different from, say, eating a soy burger  topped with soy cheese or drizzling soybean oil on your salad. This article will probably be more than you ever wanted to know about soy lecithin, but I wanted to do my best to get all the facts out on the table.

What Is Soy Lecithin?

The term ‘lecithin’ can have different meanings depending on the context, but for our purposes, it refers to a mixture of phospholipids and oil. Phospholipids are a component of the cell membrane in all plants and animals, but lecithin is most often derived from sunflower kernels, rapeseed (canola), milk, soy, and egg yolks. (1)

The specific composition of soy lecithin varies depending on its manufacturer and intended use, but on average, it contains about 35% soybean oil and 16% phosphatidylcholine. (2) Phosphatidylcholine is a type of phospholipid that is abundant in liver and egg yolks, and is the primary form of choline found in foods. (3) The remaining percentage is other phospholipids and glycolipids.

To make soy lecithin, soybean oil is extracted from the raw soybeans using a chemical solvent (usually hexane). (4) Then, the crude soy oil goes through a ‘degumming’ process, wherein water is mixed thoroughly with the soy oil until the lecithin becomes hydrated and separates from the oil. Then, the lecithin is dried and occasionally bleached using hydrogen peroxide.

There are many claims online about soy lecithin being full of nasty chemicals left over from the production process. Not surprisingly, there aren’t many credible sources describing the chemical content of commercial soy lecithin, but I have found some relevant data about the safety of soy lecithin.

Before the ‘degumming’ step where lecithin is removed, the crude oil undergoes a multi-step process to remove the hexane. (5) However, it appears that the FDA doesn’t regulate the amount of hexane residue in food products, and one paper estimated that the residual hexane concentration of soy oil is 500-1000ppm. (6) So, it’s very possible that similar concentrations remain in the soy lecithin. (For comparison’s sake, the concentration limit for hexane in pharmaceuticals is 290ppm.) (7)

According to one analysis, total pesticide residues in crude soy oil are around 400ppb. (8) Since the pesticide concentration of the oil after degumming is similar, it’s pretty likely that some of those pesticides end up in the lecithin as well.

While it’s unfortunate that soy lecithin likely contains pesticides and solvents, I would just encourage you to keep this information in perspective. We’re exposed to hundreds of chemical toxins every day in our air, water, household products, and food, and contaminants in soy lecithin will contribute only slightly to your overall toxic load. After all, we’re talking parts per million and parts per billion, and soy lecithin itself usually makes up no more than 1% of processed foods. (9)

Of course, in an ideal world, we would be able to avoid these things altogether, and I certainly recommend reducing your exposure as much as possible. It’s also a good idea to make sure your detox systems are functioning effectively. But unless you have a severe chemical sensitivity to hexane or pesticides, occasionally consuming small amounts is not worth getting bent out of shape over.

Allergies

Soy allergies are triggered by soy proteins, so whether lecithin triggers an allergic response or not depends on its protein content. One analysis found protein concentrations ranging from 100 to 1,400ppm in six different soy lecithin samples. (10) (For reference, the new FDA gluten-free labeling law requires a gluten concentration of less than 20ppm.) (11) Another analysis of six different lecithin samples found that four had sufficient protein to trigger an IgE-mediated response in people with soy allergies, while two contained no detectable protein at all. (12) However, another study performed similar testing and concluded that even if protein is present in soy lecithin, it’s not a significant allergen for people with soybean allergies. (13)

It’s clear that the source of the soy lecithin is a major determinant in whether or not it will present a problem for those with soy allergies, but if you have a soy allergy, I’d say better safe than sorry. However, because protein is present in such a low concentration, and soy lecithin itself usually makes up no more than 1% of processed foods, it’s probably not a problem for those with minor sensitivities to soy.

GMO

Most of the soy grown in the US is genetically modified, so unless the label says ‘organic soy lecithin,’ it probably came from a genetically modified soybean. You know I’m not a fan of GMOs, due to the presence of potentially transferrable DNA and potentially immunogenic proteins. However, as I discussed in the section on allergies, soy lecithin contains very little soy protein, and lecithin from some sources contains no detectable protein at all. Soy lecithin also contains very little DNA, and the DNA present is usually degraded to the extent that it’s impossible to tell whether the soy is genetically modified or not. (14) Thus, most of the risks associated with consumption of GMOs aren’t relevant for soy lecithin, and shouldn’t be cause for concern.

Phytoestrogens

Soy is the greatest food source of phytoestrogens, and one group of researchers discovered significant estrogenic activity in soy lecithin. (15) Interestingly, none of the soy lecithin they tested contained genistein, which is the predominant phytoestrogen in soy. They concluded that “a so-far unidentified estrogen-like compound” is present in soy lecithin that accounts for its estrogenic activity.

We know how problematic phytoestrogens can be, but again, the dose makes the poison. Remember, soy isn’t the only source of phytoestrogens we’re exposed to. (Did you know that flaxseed is also a significant source of phytoestrogens? In fact, one study showed that supplementation with ground flaxseed altered estrogen metabolism even more than supplementation with soy flour.) It’s definitely best to keep phytoestrogens to a minimum, and individuals dealing with cancer or fertility problems might want to avoid them more strictly. But for most generally healthy people, the small amounts of phytoestrogens from soy lecithin shouldn’t be a problem.

Toxicity

One study that has been used widely as ammunition against soy lecithin is titled “Effects of a Commercial Soy Lecithin Preparation on Development of Sensorimotor Behavior and Brain Biochemistry in the Rat.” Researchers found that soy lecithin in concentrations of 2% and 5% in the diets of pregnant and newborn rats resulted in impaired reflexes and swimming ability, along with other cognitive deficiencies.

It’s important to understand that these effects are due to choline toxicity, not soy lecithin per se. The elevated brain/body weight ratios, plus elevated acetylcholine and choline acetyltransferase levels that resulted from soy lecithin supplementation were caused by the phosphatidylcholine, and would’ve still occurred even if they had used a source of phosphatidylcholine other than soy; even egg yolks.

It would be very difficult to consume as much choline as these rats did, especially from soy lecithin. In fact, most people are deficient in choline! This is just another case of a study being misinterpreted, and you certainly don’t need to worry about soy lecithin causing developmental problems.

Therapeutic Uses

I believe I’ve covered all of the main concerns about soy lecithin, but it’s worth mentioning that soy lecithin is also being recommended and consumed as a dietary supplement. There is a growing body of research supporting its use for improving blood lipids, reducing inflammation, and treating neurological disorders. (16) For instance, one study found that after 2 months of supplementing with 500mg of soy lecithin per day, total cholesterol levels fell by 42% and LDL levels decreased by 56%. (17)

However, most of these studies involve supplementation with a purified form of soy lecithin, which usually contains less soy oil and more phosphatidylcholine than the commercial soy lecithin that shows up in foods. Additionally, isolated phosphatidylcholine is often referred to as ‘lecithin’ in scientific contexts, so some studies supplementing with ‘soy lecithin’ are really just supplementing with phosphatidylcholine.

So once again, it’s not the soy lecithin; it’s the choline. Luckily, you can derive all the benefits of phosphatidylcholine supplementation just by increasing your consumption of choline-rich foods like egg yolks and liver.

So, What to Do?

The only people who need to make a point of avoiding soy lecithin are those with severe soy allergies or chemical sensitivities, and of course, those who notice that they personally react badly to it. And if you don’t have a soy allergy, almost all of the remaining concerns about soy lecithin (pesticides, solvents, and GMOs) can be completely eliminated by purchasing products that contain organic soy lecithin.

But for the vast majority of the population, even conventional soy lecithin isn’t worth worrying about one way or the other. If it’s just as easy for you to avoid it as it is to consume it, then do so. (For example, Enjoy Life is one popular brand of chocolate that is soy-free.) Ultimately, I think most people can just enjoy their occasional chocolate treat without worrying about whether it contains soy lecithin.

  1. I have hypothyroid disease and generally avoid soy because of the disease. How is this different then the soy that is in food that I avoid. If my multi-vitamin has soy lecithin in it should I also avoid that multi-vitamin since I avoid most of the soy I find in ingredients for my food? Thanks just curious.

    • I, too, have hypothyroidism (autoimmune) and I would like to know the answer to this, as well. I have read that there are many benefits from taking lecithin supplements but, from this article, it sounds like choline is actually doing the body good.

      I am going to research choline, but would still like Chris’ opinion.

  2. I’ve recently learned that my 7 year struggle with head pain is not actually an allergy to soy lecithin (I only reacted to soy lecithin, not whole soy). It’s a Hexane sensitivity and apparently soy lecithin retains higher quantities of Hexane from processing than other substances. AND it’s not required to be listed as an ingredient. 😛
    If you are looking into finding the source of certain symptoms, and have issues with chocolate, it’s worth googling Hexane sensitivity. My biggest symptom was severe sinus inflammation which were so severe that we believed to be migraines for the first few years.

    • For severe chronic sinus problems, read up on serrapeptase. I just recently started taking it so its too soon to tell but the information looks promising!

      • Chronic sinus problems are also linked to dairy and gluten sensitivity. Try eliminating both of these for a month and see if there is an improvement. If either are the culprit it will take this long to find relief with a strict diet excluding both.

        • Absolutely correct Naomi.
          I’m 61 years old and suffered from the following for over 45 years:
          1) Glue ear (excessive ear wax)
          2) Strep throat once or even twice a year
          3) Constipation
          4) Foul smelling gas – I could clear a room of people.
          5) Sinus congestion
          6) Ear infections one or more time a year
          7) Dry skin
          8) Dark circles under eyes
          9) Restless sleep
          10) Afternoon fatigue
          11) Blurry vision’
          12) Brain fog
          13) Low libido
          14) Bad breath
          15) Headaches
          and the list could go on.

          All the above stopped when I found out I have a Gluten Intolerance problem.
          Went 100% Gluten Free and after the first 30 days, all the above problems started to fade away.

          Been GF for over 4 years and have never been sick since then. Have more energy, including sexual, then I did in my 20/s and 30’s

          As for diary,Ive known the dangers of consuming that since I was a kid. Our Doctor when I was little told my Mom to keep it away from us. We’re not baby calf’s so there is no reason for us to eat it

          Christee, go Gluten and Dairy free for 30 days and see how you feel. Allergies will go away.

        • Casein in milk causes blocked sinuses. Those intolerant will find the symptoms pronounced if they supplement with Micellar Casien as found in protein shakes used by fitness enthusiasts. Similar reactions to other cassienates found in these shakes. A few days off it and the blocked noses clear up.

  3. Soy lecithin is a compound produced from soybean oil. Soy lecithin supplements may help decrease the symptoms of certain medical conditions and are often marketed commercially as a weight-loss aid. However, there is little reputable scientific evidence to indicate that using soy lecithin regularly has any beneficial effect on weight. Talk to your doctor about the possible drawbacks of making soy lecithin a part of your weight-management regimen and about other lifestyle changes that can contribute to enhanced health and sustainable weight loss.

    • I wonder if this research, refers to the promising studies surrounding the use of D Chiro Inositol, which have suggested improvements in insulin resistance for women with PCOS and Type 2 Diabetics .? Soy Lecithin is a dietary source, high in D Chiro Inositol.

  4. Taking 2400 mg (2 pills) with each meal along with Vitamin E and Omega-3 has been a miracle at disintegrating gall stones over the course of a couple months. So glad to have avoided gall bladder surgery.

    • Am really interested in Frank’s comments re getting rid of gallstones with soy lecithin tablets. Please tell me if you take organic tablets, and what make? Thank you.

  5. I use a weightloss product that it mainly soy/protein based. I would like to know, if it is chemicals, mostly vitamins or is the soy organic. The product is MediFast.

    • Medifast is soy based. I lost a lot of weight on it but then was diagnosed with estrogen positive Breast cancer and gained all my weight back!

  6. I am soy allergic and I have had reactions to both spy oil and Soy Lecithin. Just this past week another one to Soy Lecithin in a bread that did not have it before but they now they added it to the bread recently. Had a reaction a few months back when someone use a can of supposed canola oil spray and yup they also had started adding Soy Lecithin to it as well I get fairly severe reactions so all these manufactures using Soy Lecithin in everything they make is a real issue for me and others with severe Soy Allergies. FDA makes them put Soy on the package because there are more & more of us having these bad reactions.

  7. Would you recommend a person with a history of thyroid disorder (particularly thyroid nodules) stay away from daily supplements that may contain soy lecithin?

  8. Thanks for the run down. I have an allergy to soy, such as tofu, edamame, soy milk. I have many other allergies and I know it depends on the amount and form of proteins – I have a severe reaction to some things raw, but once they are cooked beyond recognition I can tolerate them. Same with soy lectithin, it usually doesn’t cause a problem.

    • In about 2.5 million years evolution of modern men, we have been “civilized” and grown our own food for less than 10,000 years. So for almost 99.996% of the time we have been on this earth, we have lived and eaten as cave-people. Naturally, our biology and chemistry is more tuned to “cave-men” way of living.

      • This is untrue. Human lives longer as more and more caveman behaviors/traditions being abandoned. For the 99.996% of the time human live on the earth, average human only had life expectancy less than 30. Our body struggle to survive in nature because the nature is not specifically designed for us.

        • Better stats when comparing longevity, whether it be between our ancient brethren and us or across the last century (1015 years) is to compare adult death rates, not general populations that include infants and the young.

          Childhood illness, accidents etc., skew the stats. Adult comparison from age 20 gives about the best comparisons of longevity across the ages.

          Using this measure, our grandparents actually did very well compared to us (death rates 1900 and now). Cancer rates and heart disease in the adult set were very uncommon until the 1930s when they began to rise dramatically, due to denuding of grains in processing another factors (chemicals for one); today, both heart disease and cancer rates are skyrocketing and a decline in longevity is happening. The real boost in the last century to longevity were modern cleanliness, antibiotics and work related laws.

          Similarly, our adult ancient adult brethren did very well in this measure.

          Remember, survival depends on knowledge from the older generations, a vital link to past dangers. If few lived beyond age 30, it is unlikely our species would have survived.

        • Well, nature was made for us to enjoy! Its as simple as Adam n Eve who sinned and did not listen to God. Since then we all are born with sin and it has its effects on the mind(evil people putting chemicals in our foods), as well as sins effect on the physical body(sickness and age of dying). It comes down to your free will God gave you and how you use it. So those in the food industry who insist on changing things because they “think” they are creating a better crop, they will answer to God on judgement day! Believe what u want to believe, everyone has free speech, you said ur point of view about nature n man, n here is mine. As with every thing in this type of debate, you canʻt argue with truth, take or leave it, its your choice and free will. Have a good day.!

      • It is untrue because the Bible lets us know that Adam and Eve lived no longer then at most 7000 years ago. Please go to ICR, institute for creation research and check out the very qualified educated people who can back this up to anyone’s satisfaction who is not closing their minds to this truth. There is nothing wrong with eating any way you prefer to if it makes you feel healthy, but please do not base it on the lie of evolution. Not only your physical health and well being are at stake here, but your eternal destiny.

    • That’s what the establishment says. Out of place artifacts and other historical evidence suggest otherwise.

    • There is nothing wrong with eating like cave men. You say they all died young as if it was their diet that killed them, and that is a crock. Cave men and women died young because of exposure, accidents, animal attacks, insect bites, snake bites, drowning, bad weather, disease, and violence with other men and women…….but it sure as heck wasn’t their diet that made them go early. It’s foolish to make such a superficial and thoughtless assertion.

    • In response to the person who asked why would we want to eat like cavemen as they died young, you have to remember, that cave people also had environmental threats on their lives. For example, they could easily freeze to death, or be eaten by a larger animal. They could twist their ankle and be left behind by their tribe or clan because they were a burden. If food was scarce, they could starve to death. The bottom line is, they did not have all the modern day diseases that we suffer from today because we eat the standard American diet (SAD).

    • not true…hunter gatherers did not have the disease we have today…they had different problems such as predatory animals to contend with and the harsh elements of the environment. Meaning that a lot of people died but not from cancer, heart disease or diabetes which are diet related!!! The AVERAGE age of the hunter gatherers is not determined by them living to 35 years old…it’s an average for all the people who died as opposed to lived. Whether they died from hunger or cold at 2 years old or were eaten by a lion at 43 or injured themselves at 69 and bled out. There is plenty of evidence to suggest that hunter gatherers who survived the elements of their day lived very long healthy lives and because of their diets they didn’t have long term chronic health issues like we do today.

    • What is the nature of your worry?
      By the way you should explore the Budwig diet on the astounding applications of the stuff.

    • I was diagnosed with er pr positive breast cancer, it’s hard to avoid soy and products- bpa bht parabens -which mimic estrogen in our bodies which can feed cancers.. Even buying chicken and beef is hard these days bc animals are fed vegetarian diets containing soybeans to bulk them instead of hormone injections.. Even meat that says from grass fed cows still can contain soy bc they are given soybeans too is what a local farm representative told me. I believe flaxseed contains high phytoestrogens I started using ground organic flaxseed over my yogurt and I had pain etc in my breast and had to work hard to get an order for diagnostic mamogram I’m 33 and diagnosed with idc.. Long story but hopefully caught early..
      Thx for all who research about soy and soy lecithin.. I try to not google much but when I saw the jelly beans I have for my kids (and I love them too) contains soy lecithin I was shocked and my husband said that product is in a lot of candy.

    • You do not stay need to stay away from flaxseed. It is about the healthiest thing you can eat combined with cottage cheese, neither the CC nor the Flax seed seed retain their original state but turn into a very healthy supplement. Please do check out the Budwig diet. It is a miracle that has healed many of cancer and heart disease and diabetes.

    • I agree with you 158% regarding too many should be okay responses. A little bit of this “might” not hurt you or cause problems but what about 60 ingredients which are “should be okay” and then find out you have reached a toxic level?? My daughter is allergic to soy and almost died due to the soy lecithin which was hidden on the ingredients list. Thank G-d she was close to a hospital where they were able to get an epi-shot into her. She MUST carry an epi-pen with her at all times. I am also a non-gmo freak and there is no way anyone can tell me the stuff is safe.

  9. The myth, and that is what it is- a myth that soy is in someway bad for you is an unfortunate lie being told over and over again! Soy is nearly a perfect food, the phytoestrogen it contains is nothing like animal estrogens that have been linked to cancer. God gave us soy to eat, buy organic and eat to your hearts content! Don’t believ to bogus info that soy is harmful, these reports are false!

    • 1./ This is a Senior comment thread here.
      2./ 96-98% of soy in the USA is GMO. Is that included in what’s God’s gift? Or in your classification of organic? If not, do you have a good source for organic – that 2% – so we could “eat to our hearts content”?
      3. Is MSG God’s gift too? Or is it a myth that soy converts to MSG in the body?

    • Yeah, that’s why six year olds all over the world, (mostly those on the Western diet), are sprouting body hair and getting their periods.

    • Yes, allergy to soy is a lie. Next time I am in the er in anaphylaxis I will just say to myself, walk it off. Soy allergy is a lie. Silly me. I am totally sure the blood allergy tests are a lie too. I am also allergic to nuts and eggs. My son is allergic to beef and pork, although just hives. But I am sure it’s all a lie. Unless you have had your airway almost swollen shut then you should really keep your uneducated opinion to yourself.

    • Please check your information before posting. Soy especially GMO soy contains phytoestrogens which even though may be natural is not good for everyone. Estrogen driven cancers are worsened with phytoestrogens.

    • Soy lecithin is poisonous to me. Soy was good at one point, but in this case if you eat it raw it will kill you because its poisonous in its basic form. Fermented in low quantities has been OK for thousands of years in the Orient. But some idiot found that processing the Tard out of it was soo cheap the money was so easy to be made from it. They paid for US to use it and enough paid out to look away from the bad side of it.

  10. What about soy lecithin and hypothyroidism? I know it’s important to avoid soy. Is it a problem to have some in my organic acai breakfast smoothie. Sambazon “brand” acai smoothie.
    Thanks

  11. I bought protein powder and they say that it contains 240mg of soy lecithin per serving. I drink it twice a day so its 480mg. Is this to much? Oh and they also say is NO-GMO.
    I am TTC and a acupuncture lady said no soy for me. But its hard to find price decent protein powders with NO soy

    • Kamila, I have never understood why anyone would use protein powders. Protein is so complex and is found in animal and plant sources (when combined properly—if you are vegetarian).

    • Have you tried hemp protein? Or hemp seeds? Hemp seed are a complete protein, which are easily digested, and if grown in Australia they are also organic. It is legal to purchase them in Australia and take them overseas to be consumed however it is illegal to eat them in Australia. They do not have the effects of marijuana.

  12. I have a question. I was told by a midwife that if I take a soy lethicin supplement it will help me heal from ligament stretching in my pelvis. I was unable to walk for two months after the last baby I had and am now pregnant again. Right now I avoid most soy in processed food unless it happens to be in chocolate or eggs in the wintertime feed. What can I do as I have been told that soy is bad. Your article is saying different and unfortunately I am just taking peoples word about soy because I am not a nutritionist. I do not want to harm the baby as it grows but also would like to avoid this pain after the birth too. Any advice?

    • Hello Kim, If your midwife thinks lecithin is a good idea, you could try either sunflower or eggyolk lecithin. My family has soy allergies, so we don’t use soy either.

    • As long as the soy is non gmo and you do not have a soy intolerance then you don’t really have anything to worry about. You don’t want to consume large amounts of soy each day but small to moderate amounts here and there are completely harmless.

    • I would not take it, Drs mid wife’s and nurses only pass on what they are taught and usually it’s not nutrition based..
      I had a split pelvis with my second and wore a girdle and it’s the worse pain ever.. I had to use crutches and cried in pain everyday. Knowing then what I know now I would stay clear of all prescribed drugs and take serrapeptase it’s a natural enzyme that deals with information.. Good luck and always heal yourself naturally xx

      • So true, Jo. Our cultures have lost the ancient wisdoms handed down by mid-wives and natural healers. The accepted medical supporters today regurgitate what they have been taught, much of which is good, other stuff, not so much. Anything not accepted by Big Pharma and the bought medical system are tossed out as quackery.

        My mum was killed by the med profession when in hospital when she was not allowed to bring in her magnesium supplements, so I speak from experience, and resentment. She was simply being assessed at the age of 74, in a hospital suite, for independent living.

      • RiboCein is what we use to increase the natural production of intracellular glutathione and by increasing glutathione gsh inflammation goes down and pain disappears.
        Usually allergies are a result of less than perfect immune system and this some times can be corrected. The benefits of increasing glutathione production are too many to list here but allergies gone could be one of them.

  13. What about lecithin supplements derived from sunflower seeds? Your article mentions various sources for lecithin, but discusses only soy-derived lecithin. Thanks.

  14. I have a problem with soya and soya products. Anything containing soya automatically constipates me, whether it’s soya milk, soya powder, soya yogurt or soya lecithin I end up being constipated. It’s frustratingly obvious I cannot use it while other people don’t seem to have this problem. But what is the reason behind this?

  15. Just read another article, which says that only 70% of the protein can be extracted. The other 30 converts to MSG and describes a handful of negative effects all the way to liver failure… Article is http://www.ncrf.org/summary.html
    Good luck to us,
    George

    • Dear George,

      Whom ever wrote that about soy lecithin containing 70% protein is not even close to correct. By law lecithin sold in the US cannot contain more than 0.3%. I know this as fact as my company was the first manufacturer of certified organic soy lecithin in North America and regulated by the FDA as well as the USDA. The internet is a wonderful thing anyone including me can write it and it becomes fact or truth.

      Regards,
      CB

      • You (CB) are right about one thing: the Internet is a wonderful place because as you said you can post too, despite the fact that you could not quote and so apparently understand my post in more than one instances.
        1. If they extract 70 percent protein from the soy then it is not 70 that stays in it. The formula used is 100-70=30
        2. This extraction (in the article par.34) was not related to lecithin but to soy products in general, so you rambling about me having stated that soy lecithin contains 70% shows serious detoxification in a good case, permanent brain damage (together with bias) in a bad case.

  16. I take soy lecithin as a supplement because of the high phosphatidyl serine content. I don’t seem to react to it at all. Should I stop taking it?

  17. Hi,

    My daughter suffered from severe eczema last year but now it is under control. I have however noticed that eating kinder chocolate or tunacks tea cake she breaks out in a nettle like rash and is very itchy, both these products contain soya leithcin. She is still young to get an allergy test but was wondering if she has a soya allergy?

    Thanks
    B.
