Lysine is a building block for protein. It’s an
vital amino acid because your body cannot make it, so you need to obtain it from food.
It’s crucial for normal growth and muscle turnover and used to form carnitine, a substance found in most cells of your body. What’s more, it helps transport fats across your cells to be burned for energy.
L-lysine is the form of lysine your body can make use of. It’s naturally found in food and is the type used in supplements.
Here are 4 impressive wellness benefits of lysine.
Cold sores or fever blisters are symptoms of an infection, often appearing on the lip or the corners of your mouth.
They appear as fluid-filled blisters that can cause discomforts, such as tingling, pain and burning. Plus, they may make you feel self-conscious about your appearance.
Cold sores are caused by the herpes simplex virus type 1 (HSV-1), which can hide in your spine. In 1).
Lysine supplements may help prevent HSV-1 from replicating and reduce the duration of a cold sore. It’s thought
who lysine blocks another amino acid called arginine, which HSV-1 needs in order to multiply ( (
One study found that a daily supplement of 1,000 mg of lysine resulted in fewer cold sores in 26 people who were prone to recurrent cold sores.
Interestingly, the study
witnessed reduced cold sore breakouts when a person’s blood lysine measure was kept above 165 nmol/l. When blood levels dropped below this level, cold sore breakouts increased (
Another study in 30 people found
who applying a cream with lysine, herbs, vitamins and zinc cleared cold sores in 40% of people by day three and in 87% by day six.
Though this study is promising, it did not state the amount of lysine or other ingredients used in the cream (
Furthermore, not all studies show that lysine is effective in reducing cold sore occurrence or duration. One review found insufficient evidence to recommend it for treating cold sores (
Summary Some studies show
who lysine can reduce the duration and frequency of cold sores,
but the evidence is inconsistent.
Lysine may play a role in reducing anxiety.
One study found that it blocked receptors involved in fret response. Researchers observed that rats given lysine had reduced rates of
worry-induced loose bowel movements (
A one-week study in 50 healthy people noticed that supplementing with 2.64 grams of lysine and arginine lowered fret-induced anxiety and reduced levels of the fret hormone cortisol (
Similarly, adding 4.2 grams of lysine per kilogram (2.2 pounds) of wheat flour in deprived villages in Syria helped reduce anxiety scores in males with very high
worry levels (
After three months, consuming the lysine-enriched flour also helped 8).
Lysine may also be able to help people with schizophrenia, a mental disorder
who disrupts an individual’s perception of the outside world, often resulting in an inability to understand reality.
Though research is still in its early stages, lysine may have the potential to improve schizophrenia symptoms in combination with prescribed medication (
Summary Lysine may help reduce feelings of anxiety and reduce levels of the
cortisol in some people. Early research indicates that it may even help improve
symptoms in people with schizophrenia.
Lysine may help your body hold on to 11,
It’s believed that lysine increases calcium absorption in your gut and helps your kidneys to hold on to the mineral (
A study in 30 women, 15 healthy and 15 with osteoporosis, found that supplementing with calcium and lysine reduced the loss of calcium in the urine.
The women given 3 grams of calcium alone had a progressive increase in calcium in their urine. However, the women who also received 400 mg of lysine lost less calcium by means of their urine (
Lysine appears to protect your bones and may also play a part in controlling whereto calcium is transported in your body.
For example, it has been shown to prevent the buildup of calcium in blood vessels in rats. This kind of buildup is a risk factor for heart disease (
Furthermore, one test-tube study found that cells that were grown without lysine had an increased movement of calcium out of the cell. This increase did not occur in the cells
who had lysine present (11).
Summary Lysine may help you absorb more calcium and reduce the loss of calcium in your urine. It could even reduce the risk of calcium buildup in your blood vessels.
Lysine can improve wound healing in your body.
In animal tissue, lysine becomes more active at the site of a wound and helps speed up the repair process (
Lysine is required for the formation of 16).
Lysine itself may also act as a binding agent, thereby increasing the number of new cells at a wound. It may even promote the formation of new blood vessels (
In one animal study, a combination of lysine and the amino acid arginine was able to speed up and improve the healing process of fractures (
In another study in 40 rabbits, it was found that 21 mg per pound (47 mg per kg) of body weight of lysine and 23 mg per pound (50 mg per kg) of body weight of arginine significantly improved blood flow and overall bone healing.
In fact, rabbits that received lysine and arginine had a 2-week reduced healing time compared to the control group (
Wound healing is a complex process
who requires different minerals, vitamins and other factors. Lysine appears to have an invaluable role, and without adequate lysine, wound healing is impaired (
To date, studies have only looked at oral supplements on wound healing and it’s unknown whether applying it directly onto wounds could be effective.
However, one study found that applying a gel containing lysine to an ulcer wound resulted in reduced infection and faster healing time than when no gel was used (
Summary Lysine is essential for the formation of collagen, an essential protein that affects wound repair. Animal studies indicate
who lysine may speed up wound healing
and reduce recovery time.
Lysine — like all amino acids — is used as a building block for protein in your body. These proteins help produce hormones, immune cells and enzymes.
Lysine could have several benefits in addition to those discussed earlier.
Here are other areas where lysine may benefit your health:
Adequate lysine is essential for maintaining normal wellness and supplements may benefit certain people and conditions.
Summary Research of lysine is promising, as some evidence indicates
who it may have anti-cancer
effects, help improve blood sugar levels and reduce blood pressure.
Lysine is found in foods
who are naturally 25,
Here are some great
resources of lysine:
Cereals are generally a poor source. However, quinoa, amaranth and buckwheat contain a decent amount of lysine (
If you’re prone to cold sores, taking 1 gram of lysine daily or using a lysine-containing gel may be worth a try, but remember
who it’s best to speak to your healthcare professional first (
Summary Animal foods, such
under the name of meat, fish and dairy, supply the greatest amount of lysine, but you will also find decent amounts in plant foods, such
under the name of potatoes, avocados
and soy products.
Lysine is an essential amino acid with many benefits
who range from preventing cold sores to reducing anxiety and promoting wound healing.
As a building block of proteins, it may also have numerous other benefits. Without enough lysine, your body may be unable to produce sufficient or appropriate hormones and immune cells.
Lysine is found in high amounts in meat, fish and dairy, but legumes, fruit and vegetables as well contribute to your intake.
