I take lecithin as a source of choline, with each capsule providing 180mg of phosphatidylcholine, slightly more than the amount of choline found in an egg. From what I see in other comments, many people use it to lose weight? I have no idea. One main reason to take lecithin is for the choline. It is one of the most important nutrients that many people know nothing about. Most of us do not get enough of it.

It is helpful to know that choline is available in the form of an inorganic salt, which can be seen on the label as choline bitartrate. This form has limited effectiveness, while lecithin provides us with choline in the same form as found in natural foods like eggs. This form is phosphatidylcholine. There are other forms with higher absorption and greater neuroprotective benefits (such as alpha-GPC), but they are expensive for daily use.

Usually, I take one capsule on certain days of the week, depending on my diet. The benefits for me include a sense of clarity and mental stability, as well as cognitive endurance. It is difficult to describe these effects. I definitely notice when I have taken it.

Here, it should be noted that many people seek energy, "boosts," or mental clarity in various products advertised for such purposes. These usually contain a mix of different vitamins, herbs, or amino acids. It is much more likely to experience mental enhancement by taking choline.

An easy way to determine if you need choline is to eat three eggs in the morning. If you feel good, you probably do not get enough and need it in your diet. If you feel a heaviness or depression, then you do not need it. Of course, what is considered good or heavy is relative. This is still a good way to observe the effects of choline. If you generally consume eggs, fish, and meat frequently, you may be getting enough. If you are vegan or vegetarian, it is as necessary as the more well-known vitamin B12, and you will see dramatic benefits. If blood tests show elevated homocysteine levels, it is also likely that you need it and will see remarkable benefits. Choline is one of the two ways our body recycles homocysteine (the other is through folic acid and B12 - your doctor usually prescribes folic acid when they see elevated homocysteine).

You will see remarkable benefits because by recycling homocysteine, our body can produce a variety of other substances (CoQ10, carnitine, glutathione, taurine, neurotransmitters). Elevated homocysteine means that this cycle is not functioning properly, meaning a specific molecule remains trapped in its oxidized (used) form. Choline helps with this cycle, which is one of its many benefits.

The only downside here is that the capsules are gigantic. Otherwise, it is excellent if you need choline.
