Many or all of the products featured here can be from partners who compensate us. This may influence which products we write about and where and how the product appears on a page. However, this does not influencer our evaluations. Our opinions are our own.


Lysine is an essential amino acid, meaning that it is necessary for human health but cannot be produced by the body and must be obtained through the diet. Lysine plays a number of important roles in the body, including helping to build proteins, aiding in the absorption of calcium, and supporting the immune system. Some of the key functions of lysine in the body include:

  1. Protein synthesis: Lysine is one of the building blocks of proteins, and it is involved in the synthesis of proteins in many tissues and organs.

  2. Calcium absorption: Lysine plays a role in the absorption of calcium, which is important for maintaining healthy bones and teeth.

  3. Immune support: Lysine may help to support the immune system by increasing the production of antibodies and other immune cells.

  4. Herpes simplex virus: Lysine may help to reduce the severity and frequency of outbreaks of herpes simplex virus, which is a common cause of cold sores.

Lysine can be found in a variety of foods, including animal proteins, such as meat, poultry, and fish, as well as some plant-based sources, such as beans, lentils, and soy. It is also available in supplement form.

What are the benefits of Lysine?

Lysine has a number of potential health benefits, including:

  1. Supporting protein synthesis: Lysine is an essential amino acid that is necessary for the synthesis of proteins in many tissues and organs.

  2. Aiding in calcium absorption: Lysine plays a role in the absorption of calcium, which is important for maintaining healthy bones and teeth.

  3. Supporting the immune system: Lysine may help to support the immune system by increasing the production of antibodies and other immune cells.

  4. Reducing the severity and frequency of herpes simplex virus outbreaks: Some research suggests that lysine may help to reduce the severity and frequency of outbreaks of herpes simplex virus, which is a common cause of cold sores.

  5. Reducing anxiety: Some studies have suggested that lysine may have a calming effect and may help to reduce anxiety.

It's important to note that more research is needed to fully understand the potential health benefits of lysine and to determine the appropriate dosage and duration of use. It is always best to consult with a healthcare provider before taking any dietary supplement.

Which foods contain the most Lysine?

Lysine is an essential amino acid, meaning that it is necessary for human health but cannot be produced by the body and must be obtained through the diet. Some of the best food sources of lysine include:

  1. Meat: Animal proteins are generally high in lysine, with some of the best sources being red meat, poultry, and fish.

  2. Dairy products: Dairy products such as milk, cheese, and yogurt are also good sources of lysine.

  3. Beans and legumes: Beans and legumes, such as lentils, chickpeas, and kidney beans, are good sources of lysine.

  4. Soy: Soy is a plant-based protein that is rich in lysine.

  5. Nuts and seeds: Some nuts and seeds, such as almonds and pumpkin seeds, are also good sources of lysine.

It's important to note that the amount of lysine in a food can vary depending on various factors, including the specific type of food and how it is prepared. It is always best to consult with a healthcare provider or a registered dietitian for personalized dietary recommendations.

Can one over-supplement Lysine?

It is generally safe to consume lysine from food sources. However, taking high doses of lysine supplements may not be safe and can potentially cause side effects.

Consuming too much lysine may lead to an imbalance of other amino acids in the body and may interfere with the absorption of certain minerals, such as calcium, magnesium, and zinc. High doses of lysine may also increase the risk of certain health problems, such as kidney and liver damage, pancreatitis, and gout.

The safe upper limit for lysine intake has not been established, and it is not clear what the optimal dosage of lysine supplements would be. It is always best to consult with a healthcare provider before taking any dietary supplement, and to follow the dosage recommendations provided on the product label.
