Introduction
Herpes simplex virus (HSV) infections are common, with the virus remaining dormant in the body and reactivating periodically, leading to outbreaks. Dietary factors, particularly the balance of the amino acids lysine and arginine, have been suggested to influence the frequency and severity of these outbreaks. This article explores the role of a low-arginine diet, in conjunction with adequate lysine intake, in managing herpes outbreaks.
Understanding Herpes Simplex Virus (HSV)
Cold sores and genital sores are commonly caused by variants of the herpes simplex virus (HSV). It is estimated that up to 90% of the adult population is infected with HSV, which remains dormant in nervous tissue until triggered by stress or immune dysfunction. Once infected, there is no cure for herpes, and the virus remains in the body for life, typically in an inactive state.
The Role of Lysine and Arginine
Lysine and arginine are amino acids present in various foods. Research indicates that lysine may reduce the symptoms of new herpes lesions, decrease the frequency of outbreaks, and shorten healing time. Conversely, arginine may promote herpes virus replication, potentially worsening the condition. Lysine can trigger the release of enzymes that break down arginine.
How They Interact
- Lysine: Research suggests lysine has the potential to reduce the symptoms of new herpes lesions, lead to fewer outbreaks, and reduce healing time.
- Arginine: Research in labs suggests that arginine may help the herpes virus replicate, while lysine slows it down. This can mean that lysine reduces the frequency of herpes outbreaks a person experiences once they acquire the virus, but arginine can worsen the condition.
Both amino acids compete for absorption. Lysine can trigger the release of enzymes that break down arginine. Lysine is another amino acid that is thought to help counteract arginine, which can be very handy in the case of a cold sore symptoms outbreak.
Dietary Strategies: Balancing Lysine and Arginine
The theory behind a low-arginine diet for herpes management is based on the idea that reducing arginine intake while increasing lysine intake can help suppress viral replication and reduce outbreaks.

Foods High in Arginine
It might help to cut down on high-arginine foods if you have a lot of herpes outbreaks. Foods high in arginine include:
- Meats like turkey, pork, and chicken
- Fish, such as salmon and haddock
- Nuts and seeds, including almonds, pumpkin seeds, and cashews
- Legumes, like chickpeas and soybeans
- Whole grains, including oats and brown rice
- Dairy products, such as milk, yogurt, and cheese
- Chocolate (especially darker chocolate)
- Wheat
- Squash
- Peanuts, walnuts and hazelnuts (including peanut butter and other nut butters)
Foods High in Lysine
Many foods that are high in lysine also happen to be staples of a healthy diet that’s rich in proteins, vitamins, and minerals. Animal products like fish and eggs are rich in lysine. Other animal-based sources of lysine include:
- Dairy-based products: yogurt, cheese, buttermilk
- Seafood: oysters, shrimps, snails
- Meats: beef, pork, chicken
Plant-based sources of lysine:
- Vegetables and fruit: avocados, dried apricots and mangoes, beets, leeks, tomatoes, pears, green and red peppers, potatoes
- Legumes: soy-based products like tempeh, tofu, soybeans, soy milk; beans, including kidney beans, navy beans, black beans, chickpeas and hummus, lentils, edamame
- Nuts, seeds, and grains: pumpkin seeds, pistachios, cashews, macadamia nuts
- Grains: quinoa, amaranth, buckwheat, seitan
Balancing Intake
However, many high-arginine foods also contain a lot of lysine, including poultry, fish, some nuts, seeds, and beans. Shrimp, shellfish, eggs, and lentils also provide lysine. Plenty of nutritious foods are on this list. Some, like yogurt, milk, and fish, feature in breakfasts around the world. It’s vital to balance the risk of herpes recurrence with the shortfall in your nutritional intake if you cut out certain foods, such as whole grains. One good strategy is to make sure to balance out your high l arginine foods, are foods rich in lysine.
The Importance of Overall Diet
As with most health complaints, diet is an important factor for preventing cold sore outbreaks. You may not be able to prevent outbreaks entirely, but you can minimize their occurrence by eating a well-balanced diet high in lysine-rich, whole foods.

Lysine Supplementation
You can also maintain the intake of these foods while taking a lysine supplement to balance out arginine intake, which some integrative medicine practitioners recommend. If you're having trouble giving up these arginine-rich foods - which we'd understand as many of them are staple parts of a healthy, balanced diet - then you may want to consider taking a daily lysine supplement to help balance your arginine intake and add to your cold sore treatment plan.
Dosage
Dosage recommendations for lysine vary according to what you’re using it for. The typical dietary guideline for lysine is 1 gram (g) or 1000 milligrams (mg) per day.
Research on Lysine Supplementation
Study results on the effects of these supplements on herpes outbreaks, such as cold sores, have been mixed. Also, the dose required to see an effect on herpes or the long-term effects of lysine supplementation on health are not yet clear. L-lysine supplementation appears to be ineffective for prophylaxis or treatment of herpes simplex lesions with doses of less than 1 g/d without low-arginine diets. Findings from 1 small double-blind, randomized, placebo-controlled trial suggest that doses in excess of 3 g/day may reduce recurrence rates and improve patients’ self-reported symptoms. Longer-duration, randomized controlled studies of lysine doses exceeding 1.2 g/day are required to definitively test its role in herpes simplex prophylaxis and determine the minimum reliably effective daily dose. This literature review uncovered no convincing evidence that lysine can be used to treat active herpes simplex lesions.
Precautions
Keep in mind that lysine supplements aren’t subject to FDA monitoring. Only buy lysine supplements from suppliers that you trust, and those that are NSF certified or rate well with Consumer Lab. Consuming too much lysine can lead to abdominal cramps and diarrhea. You can avoid side effects by staying within the recommended daily dose of any product you use. Since lysine can increase your body’s ability to absorb calcium, you should ask a doctor about taking lysine if you’re already using calcium supplements. Women that are pregnant or breastfeeding should speak to a doctor before taking lysine or any other supplements.
Other Potential Benefits of Lysine
Lysine is an essential amino acid that your body doesn’t naturally produce. Lysine is one of the essential amino acids that your body needs to build proteins. Since our bodies can’t produce essential amino acids, including lysine in your diet is the only way to make sure you’re getting it.

Consuming more lysine - through your diet or through supplements - may improve certain health conditions. It may also improve your health overall by helping your body produce collagen, digestive enzymes, antibodies, and protein hormones. When possible, try to get your lysine naturally, from foods.
- May bring down blood pressure: In one study on both men and women with hypertension (high blood pressure) who were lysine-deficient, taking lysine supplements brought down their blood pressure.
- May help with symptoms of anxiety: Lysine supplements used in one 2004 study from Syria found improvement in people with long-term anxiety and an acute stress response. Another trial from 2003 that used lab rats concluded that lysine may be helpful to treat intestinal distress linked to anxiety.
- May help insulin resistance: A small study from 2009 that followed 13 people over the course of 9 years has suggested that lysine ingestion may improve glucose response for people who have diabetes, although current research is somewhat conflicting.
Other Ingredients That May Help Prevent Herpes Outbreaks
Limited research has shown that curcumin, the active component that helps provide turmeric’s anti-inflammatory properties, might help block the herpes virus’s entry into cells and stop it from copying itself. In test-tube studies, this has demonstrated an antiviral effect against the life cycles of HSV-1 and HSV-2, different types of herpes viruses.
While applying these results to outcomes in living human bodies isn’t possible, they show promise. Adding turmeric to foods is safe and flavorsome, so sprinkling this common spice on your breakfast carries no risk, even though only weak evidence supports its benefits for herpes management. Turmeric is also available as a supplement.
Additional Home Remedies
When it comes to home remedies for cold sores, adding some specific elements to your regime such as a petroleum jelly lip balm, or Bio-propolis ointment may also be protective against the unwanted symptoms of cold sores.
Important Considerations
- Individual Variation: Dietary triggers for herpes outbreaks can vary from person to person.
- Overall Diet: A well-balanced diet rich in whole foods is crucial for overall health and immune function.
- Medical Advice: Dietary changes should not replace antiviral medications or other treatments prescribed by a healthcare professional.
