Depending on whom you ask, lecithin has two definitions. First, it refers to commercial lecithin, such as lecithin supplements, that come either from soybeans or egg yolk. Second, lecithin is a term used synonymously with phosphatidyl choline (PC), a phospholipid that is found in the cells of all living organisms, plant and animals alike.
As a phospholipid, lecithin or phosphatidyl choline composes one of the 10 main types of lipids in cell membranes, including cholesterol, glycolipids, spingomyelin, phosphatidylethnolamine, phosphatidyl inositol, phosphatidyl serine, phosphatidyl glycerol, diphosphatidyl glycerol (cardiolipin), and phosphatidic acid. Phospholipids have hydrophobic tails, which means they continually push away from the watery areas surrounding the cell and maintaining the fatty cholesterol, which gives rigidity to the cell membrane. This function of lecithin is often termed as its “emulsifying action,” and one of the main uses of commercial lecithin is actually as an emulsifying agent used to keep butter, margarine, chocolate bars, etc.
However, when talking about lecithin supplements, what people generally refer to is phosphatidyl choline, or more specifically its purified form, which is choline, a B-vitamin and an essential nutrient.
There is much health benefit attributed to both phosphatidyl choline and choline found in lecithin supplements. The compound has been associated with treatments for a variety of diseases from lowering high blood cholesterol, to reducing heart attacks and stroke, atherosclerosis, dispelling symptoms of cirrhosis of the liver and gall stones, and improving memory loss. Lecithin supplements are even currently marketed as aids to weight loss.
However, it should be noted that phosphatidyl choline itself is not an essential nutrient. Our bodies already have it and can produce more of it should the need arise. Choline, on the other hand, can only be derived from the foods we eat. A deficiency in this compound could lead to various debilitating diseases, not least of which is cirrhosis of the liver. The good thing about it is that phosphatidyl choline is normally synthesized by the body to form choline, so taking in lots of lecithin supplements containing a high percentage of the compound could help boost your supply of choline and overcome a potential deficiency.
Lecithin supplements are one of the few emulsifiers approved by the United States Food and Drug Administration as GRAS or Generally Recommended as Safe for consumer use. There are no Recommonded Dietary Allowances for lecithin supplements; however some scientists do recommend an Adequate Intake for choline. For men, 550 mg is often recommended as adequate for daily use while for women, 425 mg is needed.
Both choline and lecithin supplements are available in the market. However, if you want the most effective way to elevate your choline levels, the intake of lecithin supplements is often recommended. Anyway, your body will just synthesize the phosphatidyl choline into choline for use. Another reason that choline supplementation is sometimes discouraged is that taking large amounts of choline supplements has been known to produce a fish-like smell in the user.
Taking lecithin supplements with meals is the best way for your body to absorb the nutrients. Consider sprinkling lecithin supplements in granular form unto your food.

Lecithin Sources
... of lecithin in the body, we need to turn to other lecithin sources, over and above the normal diet. Soy Foods One of the most popular lecithin sources is soy. In fact, most lecithin sources sold commercially today are derived from soybean oil. In the United States, soy food consumption is increasing annually. This may help to increase the level of lecithin consumption. Soy food is one of the most versatile of lecithin sources. The soybean can be eaten whole after it has been boiled or roasted. It can also be transformed into a great variety of foods, the more popular of which are tofu, meat alternatives, soy sauce, soy flour, and soybean oil (usually called vegetable oil). Supplements Another alternative to getting adequate supply of lecithin is supplementation. Supplements are excellent lecithin sources; one tablespoon of lecithin granules contains as much as a 1, 725 mg/serving. A soft gel...
Lecithin Weight Loss
Lecithin weight loss supplements are highly filtered. That means they contain less than 35% of phosphatidyl choline while the rest are made of various substances. Majority of these lecithin weight loss supplements are derived from soybeans, although egg yolk lecithin weight loss supplements can also be found. But while lecithin weight loss supplements are valued for their phosphatidyl choline content, the real benefit you get from supplementation is Lecithin Supplements the boost in choline levels your body receives. As an essential nutrient, your body cannot manufacture choline and hence you always depend on the foods that you eat and supplements in order to get your supply. However, there have been reports that people who take large amounts of choline supplements end up emitting a fish like smell, discouraging others from taking the...
Lecithin Supplement
... nutrition at the University of North Carolina in Chapel Hill Steven Zeisel, M.D., Ph.D. says that lecithin also helps to maintain the structural integrity of cells. He explains, "Without lecithin, nothing would survive, because you wouldn't be able to separate the various compartments within cells, nor would you be able to separate cells from each other." When phosphatidyl choline enters the body, it turns into choline, an essential nutrient. The claims revolving around lecithin supplement can all be traced back to this element - choline. As an essential nutrient, choline cannot be manufactured inside the body. In order to get our supply of it, we must turn to our daily diet and supplements such as lecithin supplement. Choline is very important because it is one of only two nutrients needed by the liver to promote the breakdown of fats. The other nutrient is methionine, an essential amino acid. Fat-Emulsifier Choline is a lipotropic agent. As such, it promotes or encourages the export of fat from the...
What is Lecithin
... of commercial lecithins sold in the market today come from soybean (mostly), sunflower, and grape seed. When talking about plant lecithins, the most common source is soybean. When Maurice Gobley, the French scientist discoverer of lecithin, found lecithin in egg yolk in 1950, egg yolk was the sole source of lecithin used by Lecithin Supplements the commercial food industry. However, by the 1930s, the time when soybean lecithin was discovered, egg yolk no longer held its former place of being the major source of lecithin for commercial use. Today, it is not even a major source of lecithin in nutritional supplements. The reason may be that lecithins that come from plants are GRAS or generally regarded as safe. Who needs to take lecithin? When you know all there is to know about what is lecithin, then you probably know already that the substance is synthesized by the body from food. This means that it...
Health Lecithin
... we have for our daily diet. However, if you want foods that are rich in lecithin, then turn no further from those same foods that are high in cholesterol and fats. The most concentrated sources of dietary lecithin are organ meats, red meats, and eggs, which is where lecithin got its name by the way - lekithos, Greek for "egg yolk." But with today's current trend in low-fat, low-calorie diet, many have turned away from lecithin-rich foods. This reduction may likely result in an inadequate dietary intake of lecithin and choline, a component of lecithin. In order to make up for the lecithin lost through reduction of egg consumption, organ meats, and red meats, health lecithin supplements are taken. Why is it Good? As a phospholipid, lecithin is both phosphorus and fats (lipids). As such, it is an excellent source of essential fatty acids, which are a part of each molecule. Because phospholipids are both fat loving (lipophilic) and water loving (hydrophilic), lecithin helps protect the cell's essential fatty acids, which...
Lecithin Side Effects
... run out of lecithin anytime soon. You can always get your supply of lecithin from the foods that you eat, like eggs (yolks), soybeans, sunflower, grape seed, wheat germ, to name a few. Lecithin has been the subject of various extensive research studies, particularly concerning its role in degenerative diseases. Because of its being a major component in the structure of myelin sheath and nerve cells, scientists believe that lecithin side effects include a Lecithin Supplements possible cure for conditions involving cognition or those that affect the mental processes used to acquire, maintain, retrieve, and utilize information. One example is dementia, which is a mental condition that may due to stroke. It has been observed that people who suffer form this condition often have a low level of a natural chemical known as...

... neurotransmitter, acetylcholine. This led others to believe that lecithin may help improve the cognitive functions Lecithin Supplements of the brain, even going so far as to help enhance our memories. But while there are quite a number of studies that seem to show evidence of the benefits of lecithin, there is little in the way to show a real connection between improved conditions and the taking of lecithin supplements. Instead, what doctors have observed is a concerning number of reports of soy lecithin allergens. Soy Allergy In line with the increasing use of soy products today, soy lecithin allergens also arose and allergic reactions arose. It was in the early 1980s that Stuart Berger, MD, labeled soy lecithin allergens as one of the top seven allergens - sometimes known as...
Organic Lecithin
... lecithin could also be added into recipes to improve flavor and to act generally as an emulsifier. Then, in the 1930s, soybean consumption experienced a boom and that when it was discovered that the sludge that was the by product of soybean processing actually contains about 1.8% hydrophosphatides, which consist of organic lecithin. Through a process called "degumming," organic lecithin was extracted from the sludge and sold as an alternative to egg lecithin. Organic lecithin that comes from plants is generally regarded as safe. That is because animal lecithins are often excreted through the kidneys which may contain toxins and harmful substances, whereas you will never face that kind of danger with organic lecithins from plants. As a result, majority of the organic lecithin sold commercially in the market consist of soybean lecithin. Besides being used in foods that we generally consume, organic lecithin has also expanded its function to include animal feeds, cosmetics, paints, and metal tape. The...
Lecithin Benefits
... layer that is responsible for regulating the passage of nutrients into and out of cells. Lecithin forms one of the major components of this membrane. In addition, lecithin is also a major component in the protective sheaths that surround the brain, muscles, and nerve cells. Although lecithin is essentially a lipid, it is also partially soluble in water due to its phosphate group. This unique structure of the compound contributes to one of its lecithin benefits, which is to act as an emulsifying agent, making it a convenient ingredient to use in many processed foods. Lecithin for Health While there is little doubt that lecithin is indeed a powerful emulsifier, there is more to lecithin benefits than that. For decades, people have been touting that Lecithin Supplements treatment for high cholesterol is one of the many lecithin benefits. There is little evidence to support this claim, mostly because when the studies conducted were largely unreported. Still, these claims about lecithin benefits on...

... bar or a piece of chocolate inside the freezer. Wait a few minutes before taking it out. You will notice that the whole bar is covered in white. That's lecithin effects in action right there! Often used as a food additive, lecithin was first derived from egg yolk in 1950 during Lecithin Supplements its discovery by French scientist Maurice Gobley. In fact, that is how it got its name - lethikos, the Greek word for "egg yolk." But by the end of the 1930s, it was soon discovered that lecithin may also be extracted from crude soybean oil after it has undergone a process called hexane extraction. Lecithin Effects as an Emulsifier The food industry is among the first industries that discovered the wonderful lecithin effects of this natural emulsifier. Since its discovery, it has been used in foods such as chocolate, cheese, margarine, and salad dressings. Acting as an emulsifier, the lecithin effects...
Lecithin Granules
... valuable not only in weight loss programs but also in the prevention of atherosclerosis and heart disease. When PC enters the body, it is immediately broken down into choline, a substance that scientists have discovered as an essential nutrient, which means that we can't live without it. To prove this, several studies have shown that within 30 days of a choline deficient diet, indications of liver problems will manifest. Phosphatidyl Inositol (PI) Unlike phosphatidyl choline, phosphatidyl inositol, or PI for brevity, is not purely a phospholipid. The substance contains an alcohol, inositol, with a ring structure, which acts as a substrate for a large number of enzymes involved in cell signaling - the process by which a cell converts one kind of signal or stimulus to...
Facts about Lecithin
... lecithin is actually a Lecithin Supplements complex mixture of phospholipids, glycolipids, triglycerides, sterols, and small quantities of fatty acids, carbohydrates, and sphingolipids. Its primary phospholipid components include phosphatidylcholine (PC), phosphatidylethanolamine (PE), phosphatidylinositol (PI), and phosphatic acid (PA). Now, since lecithin is present in the cells of all living organisms, you must think and believe that it is an essential nutrient. Certainly, that is what the adverts have been telling us. However, the facts about lecithin will tell you that the substance actually comes from the diet and is only synthesized in the body. Therefore, it is not an essential nutrient, although it may have some beneficial effects. As a phospholipid, the facts about lecithin will indicate that the substance is a major component in cell membranes. Lipids make the cell membrane semi-permeable - that is, it allows some substances in while keeping other substances out....
Structure of Lecithin
... development. On the other hand, docosahexaenoic acid is required for normal development of the brain, nervous system, and visual acuity. Consequently, both these important components of the structure of lecithin play a vital role during pregnancy and infancy. Since babies have only limited capacities, they need arachidonic acid and docosahexaenoic acid to synthesize fatty acids from their precursors. Structure of Lecithin: Soy Markedly different from egg yolk lecithin, the structure of lecithin derived from soy actually consists of three types of phospholipids: phosphatidylcholine (PC), phosphatidylethanolamine (PE), and phosphatidylinositol (PI). Since soy lecithin is obtained in the process of degumming crude soy oil, it contains Lecithin Supplements minimal amounts of hydratable compounds (1.8%), comprised primarily of phosphatides. After going through the synthesizing process, the resulting structure of lecithin is 30-35% crude soy oil and 65-70% phosphatides. Oil can then also be removed completely with the addition of acetone. In the structure of lecithin derived from soy, the phosphatides consist of glycerides, which are the basic components of soy oil. However,...
Lecithin is Powerful
... greatly needed by the body. They are polyunsaturated fats and are a vital pat of each molecule. By keeping these fatty acids from becoming damaged due to oxidation, phosphatidylcholine or lecithin stabilizes them, keeping them away from harmful substances. Lecithin is powerful because of its unique structure. It is both fat loving for the fatty acids (lipophilic) and hydrophobic, meaning it will always be moving away from areas with lots of water. This tendency of lecithin to move away from watery areas Lecithin Supplements and towards areas with lots of fats is the reason why lecithin is powerful, especially when it comes to protecting fatty acids. In moving towards the fatty acids and moving away from the watery areas, lecithin molecules form a ring around the fatty acid molecule that keeps it away from oxidation-causing molecules....
Liquid Lecithin
... digestion. As an emulsifier, the function of liquid lecithin is to separate the fatty acids in the bile and protect them from the ravages of oxidation. The compound also helps keep the liver cells healthy so they can continue doing their function of filtering and cleansing the blood of all toxins and harmful molecules. Sources Liquid lecithin can be found in nearly all kinds of food. But the richest sources of liquid lecithin are those that are high in Lecithin Supplements fat and cholesterol, such as eggs, red meat, organ meat, etc. Soybeans are also good sources of liquid lecithin. In fact, majority of commercial lecithin sold in the market today are derived from soybean oil even as the first lecithin was separated from egg yolk in 1850. Every person needs adequate supply of liquid lecithin. While it is true that...
