Lysine is one of the essential amino acids of our body, and it is in charge of providing the body with the proteins it needs to grow. Moreover, it helps to maintain the balance of the nitrogen levels in the body. It also plays an important role in the regulation of cholesterol and in the production of calcium and collagen.

Lysine is involved in the production of enzymes, hormones, and antibodies that can inhibit some infections caused by viruses. It is particularly useful for the treatment of labial herpes caused by simple herpes type 1 virus. It is also recommended as a natural remedy to treat other health problems, such as genital herpes and zoster herpes.

Table of contents

What is Lysine?

Lysine is an amino acid found in the proteins of some foods, such as beans, cheese, yoghurt, meat, milk, wheat germ, and other proteins of animal origin.

It is an essential amino acid for human beings, since the body cannot produce it on its own. Therefore, we must provide it to the body through food or by using dietary supplements. A person with a normal body weight of 70 kg needs to consume between 800 to 3000mg of lysine daily.

Clinical studies have shown that eating lysine regularly helps to prevent outbreaks of labial and genital herpes.

The antiviral effect of lysine has proven to be efficient for the reduction of arginine, which favours the reproduction of the simple herpes virus.

Foods that contain Lysine

Since the body cannot produce lysine by itself, which means that it belongs to the essential amino acids group and must be provided to the organism through foods rich in protein, including meat (especially red meat, pork, and poultry), cheese (particularly parmesan), certain types of fish (such as cod and sardines) nuts, eggs, soy, beans, legumes, and dairy products.

The benefits of Lysine for health

Adding a supplement of this amino acid to the diet has many benefits for health, including:

  • Osteoporosis prevention
  • Treatment and prevention of cold sores
  • It improves the functioning of the immune system
  • It reduces anxiety and nervousness

Lysine properties

Lysine and herpes

The outbreaks of herpes are painful, unsightly, and contagious. Between a 60 and 90 per cent of the population has the herpes simplex 1 virus. The cause of labial herpes is mainly due to an infection suffered during childhood.

The herpes simplex type 2 is the usual cause of genital herpes. However, it can also cause an outbreak in the mouth area.

Lysine can help to prevent herpes infections from spreading. Clinical studies have shown that lysine treatment is very positive for those who suffer from herpes.

The development of the infection can be avoided by consuming a dose of lysine and by increasing the amount if the infection develops.

Lysine and collagen

Among the multiple properties of lysine, we can find its role in promoting the growth and maintenance of connective tissues. Collagen gives structure to the cells and keeps them in perfect conditions. Lysine along with proline and vitamin C help with the formation of collagen and prevent its deterioration by blocking the harmful enzymes.

Lysine and the immune system

Lysine plays a very important role in the optimal functioning of the immune system. A deficiency of this basic amino acid produces a deterioration of the immune system.

This is the reason why an appropriate supplementation of lysine is very important for health. However, the body cannot produce this amino acid by on its own, so it must be provided through food or by using dietary supplements.

Many foods contain lysine. But in the case of those who suffer from allergies to certain foods or who follow a vegan or a vegetarian diet, it is better to use lysine supplements. The immune system is further reinforced if lysine supplements are used at the same time as arginine supplements.

Lysine and osteoporosis

Lysine encourages the absorption of calcium by the body and reduces the amount that is lost through urine. Clinical studies with animals have shown that dietary supplements increase the absorption of calcium in the body and this gives additional protection against bone loss.

Calcium is essential for the formation of the bones. As a result, researchers believe that lysine helps prevent the bone loss associated with osteoporosis. However, this study of osteoporosis treatment has not yet been confirmed for human beings.

Who can benefit from using Lysine dietary supplements?

Lysine has several positive effects and adding it to the diet can be particularly helpful in the following cases:

  • For the treatment of metabolic disorders
  • In cases of lysine deficiency
  • To increase the levels of calcium in the organism
  • To increase the physical performance of athletes and sportspeople
  • To treat pain
  • To reduce anxiety and stress

Lysine, interactions and combinations

There may be interactions when combined with large amounts of arginine, since both amino acids share the same transport system in the organism.

In this case, a very high dose of arginine in the diet can trigger a reduction of the lysine levels. If this happens, we should cease the administration of arginine.

Lysine intake, recommendation

In the case of adults and children over 13 years of age, the daily recommended intake is 12 mg per kg of body weight. An example of the dose prescribed during an active herpes outbreak is between 3000-9000 mg daily, divided into several individual doses throughout the day.

In order to prevent a new outbreak, many people use 1000 mg a day. However, it is advisable to consult your doctor about the adequate amount of lysine for the diet of each individual case.

Lysine dietary supplements are available in different forms (l-lysine or lysine) and formats (capsules, tablets, creams, or in liquid form).

Why should you use Lysine supplements?

  • Lysine is an essential amino acid which cannot be generated by the body and must be provided through the diet or by using supplements.
  • Studies have shown that consuming lysine regularly helps to prevent herpes outbreaks.
  • Lysine is very important for growth.
  • Lysine also plays an important role in the production of carnitine. Carnitine is a nutrient which is transformed into energy, along with fatty acids. Lysine also helps to reduce cholesterol levels.
