Lecithin is a term for a mixture of compounds derived from animal and plant tissues. Lecithin has been shown to reduce cholesterol (1), dampen cortisol responses in situations of social stress (2), and to increase semen volume. One of the benefits of lecithin sexually is that it increases semen volume

Lecithin is a term for a mixture of compounds derived from animal and plant sources. Lecithins are amphiphilic (meaning they attract both water and fats) and belong to a larger group of compounds called phospholipids.
Phospholipids like lecithin comprise important parts of the brain, blood, nerves, and other tissues (3).
Lecithin supplements are used for the following purposes:
1) To treat certain medical conditions.
2) Increase semen volume and orgasm intensity.
3) Produce more precum.
4) Improve heart health.
5) Improve cognition and focus.
The major sources of lecithin in diet are from red meat, seafood, eggs, and legumes (4). While there is no recommended daily intake amount, dosages found to be effective for reducing cholesterol, reducing stress, and increasing semen volume are generally easiest to obtain when taking a daily lecithin supplement in conjunction with a diet rich in whole foods.
One of major lecithin benefits for men is that Lecithin supplementation reliably increases semen volume. This has been found to be true in both in humans and in animals. While no double-blinded human studies on semen volume and lecithin have been carried out, lecithin supplementation in animal models have shown significant increases in semen volume.
Lecithin supplementation over a period of three months increased semen volume by 17.5% in rabbits (7) and 14.2% in roosters (8). Markers of sperm health and mobility were also improved in both studies.
Lecithin alongside other supplements such as pygeum and zinc increase the volume enhancing effects of lecithin. Nitric Oxide increasing supplements that increase blood flow such as L-Arginine can improve sexual performance and pleasure. Combining lecithin with a semen flavor enhancing supplement (such as bromelain) is another popular combination.
As discussed in the previous section Lecithin supplementation reliably increases semen volume. Precum is largely composed of the same things as ejaculate or cum. If you increase semen volume, you increase precum. Lecithin therefore can be expected to increase the amount of precum that you produce.
While individual physiological differences set each person's baseline levels of precum lecithin supplementation is one way to reliably increase the amounts that you produce. Precum volume is also a function of sexual arousal. The more turned on you are, the more precum you produce.
Load Boost is specially formulated to increase semen volume, precum volume, and orgasm intensity.
There is robust data showing that lecithin supplementation reduces total cholesterol in patients while high cholesterol.
In one study, administration of 500 mg of lecithin per day reduced total cholesterol levels by 40% and LDL ("bad cholesterol") by 56% in a two month period (5).
This is a considerable reduction in cholesterol levels on the order of many pharmaceutical interventions, for example, statins can be expected to reduce LDL by between 30-50% (6).
In the diet, lecithin is the main source of choline (3). Choline is an essential nutrient and critical to the nervous system. Choline is commonly supplemented to improve memory and mental functioning.
Lecithin is also converted into acetylcholine, a substance that is critical for transmitting nerve impulses. Lecithin was shown to improve memory, mood, and cognition in a three month, double-blind, placebo-controlled trial (9).
Lecithin is naturally occurring in a variety of common foods such as meat, eggs, fish, and legumes. Most individuals consume lecithin in some form within their day-to-day diet.
As a supplement and as a food additive Lecithin is generally recognized as safe (GRAS) by the FDA (10). This means that it is considered safe by experts under the conditions of its intended use.
Lecithin is sourced from eggs, soy, and sunflower seeds. While some protein residues may remain from the manufacturing process these protein residues are normally not high enough to provoke allergic reactions (11). Nevertheless, exercise caution if you are allergic to these foods. The highest quality lecithin supplements are typically isolated from soybeans.
