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.

Lecithin is available as an ingredient in:

The Short Answer.

  • Studies suggest that lecithin reduces cholesterol, reduces stress, and improves cognition.
  • Lecithin reliably increases semen volume and improves sperm health.

What is Lecithin?

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 can also be found naturally in foods. Foods that contain lecithin include:

  • Soybeans
  • Wheat germ
  • Peanuts
  • Liver
  • Egg yolks

Lecithin can also be found in over the counter supplements.

Why take a Lecithin supplement?

Lecithin supplements are commonly used to improve the following aspects of one's health:

  1. Testosterone levels. Testosterone is a sex hormone that’s responsible for your fertility and sex drive.
  2. Sperm count. The amount of sperm your body naturally produces can affect how much semen you produce
  3. Sperm motility. Healthy sperm are measured by how well and how fast they can swim in your semen. This can affect your semen volume.
  4. Erectile dysfunction. Your ability to get and keep an erection can affect how much semen you produce.
  5. Libido. Your desire to have sex can impact your semen volume.

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.

Benefits of Lecithin for Sexual Health

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.

Seminal fluid volume and sperm quality

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.

Erection firmness

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.

Pre-cum volume (pre-ejaculatory fluid)

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.

In addition to natural sources of Lecithin, it can also be found in supplements like Load Boost, which is specially formulated to increase semen volume, precum volume, and orgasm intensity.

Lecithin for Heart Health

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).

Lecithin for Cognition and Focus

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).

Is Lecithin Safe?

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.
