About Mackerel
Mackerel is a medium-sized, oily fish that has a strong, distinctive flavor and a firm texture. It is often sold fresh, smoked, or canned. Mackerel is rich in omega-3 fatty acids, which have anti-inflammatory and anti-clotting effects.
Mackerel is high in protein, omega-3 fatty acids, selenium, vitamin B12, and niacin. It also contains moderate amounts of mercury, which can be harmful if consumed in excess. Mackerel consumption should be limited to avoid mercury poisoning, especially for pregnant women and children.
Lysine Considerations
Lysine is an important amino acid that the human system needs to build proteins. It is one of the nine amino acids that the body cannot make by itself, so it has to come from the food we eat.
Lysine has many functions in the body, such as helping with growth, healing, energy, immunity, and collagen production.
Lysine may also have some effects on the herpes virus, which causes cold sores and genital sores. Studies have suggested that taking lysine supplements or applying lysine cream may help prevent or treat these infections by blocking the amino acid arginine, which the virus needs to grow.
Lysine is an essential amino acid that supports immune function, collagen synthesis, and calcium absorption. Mackerel provides a high amount of lysine, which may help prevent or treat cold sores, herpes, and osteoporosis.
Arginine Considerations
Arginine is an amino acid that our body needs to make nitric oxide, a compound that helps with blood circulation, energy, and communication between cells.
Arginine can boost your overall health and performance, such as lowering your blood pressure, healing your wounds, and boosting your exercise endurance.
Arginine can be made by the human body or obtained from foods like meat, dairy, nuts, and soy.
Unfortunately, the herpes virus is known to "feed" on arginine, and having a diet higher in arginine than lysine may increase the occurrence and severity of cold sores and herpes outbreaks.
Arginine is a semi-essential amino acid that plays a role in nitric oxide production, blood vessel dilation, wound healing, and growth hormone secretion. Mackerel provides a moderate amount of arginine, which may improve cardiovascular health, erectile function, and exercise performance.
Lysine-Arginine Ratio Analysis
The lysine-arginine ratio is a measure of how much lysine and arginine are present in a food. Lysine and arginine are both amino acids that are involved in protein synthesis and other metabolic processes.
That said, they have opposite effects on the herpes simplex virus, which causes cold sores and genital herpes. Lysine can prevent the replication of the virus, while arginine can stimulate it.
Because of this, eating foods that have a high lysine-arginine ratio may help soothe the frequency and severity of herpes flare-ups.
Some examples of foods that have a high lysine-arginine ratio are dairy products, fish, poultry, fruits, and vegetables.
These foods can provide the body with enough lysine to block the uptake of arginine by the virus, and thus prevent its growth and spread.
Because Mackerel contains much higher levels of lysine than arginine, it is highly recommended for people who suffer from herpes, as it may prevent outbreaks.
The lysine-arginine ratio is a measure of the balance between these two amino acids in a food. A higher ratio indicates a higher lysine content relative to arginine, which may be beneficial for people with viral infections, such as herpes simplex. Mackerel has a high lysine-arginine ratio, which may help inhibit viral replication and reduce the severity and frequency of outbreaks.
Nutrient Density & Portion Control
Nutrient density is a measure of how rich a food is in amino acids relative to portion size. We calculate it as (Lysine + Arginine) / 100, which gives you a quick sense of how much total amino acid content is packed into each 100g serving.
Mackerel has a medium nutrient density (28.19), which is a good balance. You can enjoy this food in moderate portions without needing to be overly restrictive. It's a solid choice for herpes management when paired with other lysine-rich foods.
💡 Tip: Use the density metric to quickly gauge portion control. High-density foods are nutrient-dense and should be enjoyed mindfully, while low-density foods give you more flexibility in serving sizes.
Dietary Considerations for Herpes Management
Category Overview
Fish is a great source of lysine, which can help inhibit or reduce herpes outbreaks. Fish also contains omega-3 fatty acids, which can lessen inflammation and improve cardiovascular health. Most fish have more lysine than arginine, but some fish have a higher ratio than others. Salmon, catfish, whitefish, mackerel, trout, and sardines are some of the fish that have the most lysine compared to arginine.Practical Recommendations
As well as eating foods that have a high proportion of lysine to arginine, you can also adopt some other dietary habits to deal with herpes outbreaks. For instance:
Eating a balanced and nutritious diet that supports your immune system and reduces inflammation. This means consuming plenty of fruits, vegetables, whole grains, lean protein, and healthy fats, and avoiding processed foods, added sugars, alcohol, and caffeine.
Avoid alcoholic beverages and caffeine which can overstimulate your body, leave you dehydrated, and compromise your immune system.
You may want to take l-lysine supplements. L-lysine is known to prevent herpes outbreaks and it can help stop a cold sore in its initial stages by "starving" the virus of arginine before it has a chance to cause a cold sore.
Taking other food supplements that can improve your immunity and protect your cells from oxidative stress, such as vitamin C, zinc, selenium, and antioxidants.
Avoiding foods that can cause allergic reactions or sensitivities, such as gluten, dairy, nuts, eggs, or shellfish. These foods can trigger inflammation and weaken your immune system, making you more susceptible to outbreaks.
Eating foods that can soothe your symptoms and speed up your healing process, such as honey, plain yogurt, aloe vera, and chamomile tea. These foods have anti-inflammatory, antiviral, and antibacterial properties that can reduce pain, swelling, and itching, and promote tissue repair.
Is Mackerel Safe for Shingles?
Yes, Mackerel is an excellent choice for shingles management. With a lysine-to-arginine ratio of 1.53, this food is rich in lysine, which supports your body's natural defenses against varicella-zoster virus (VZV) reactivation.
Lysine is known to inhibit arginine metabolism, a key factor in viral replication. By choosing lysine-rich foods like Mackerel, you're actively supporting your immune system's ability to keep VZV dormant.
Include Mackerel regularly in your diet to maintain a lysine-favorable amino acid balance. Pair it with other lysine-rich foods for maximum antiviral support.
✓ Shingles-Friendly: This food's high lysine content makes it a smart choice for reducing herpes zoster reactivation risk.

Is Mackerel high in arginine?
Mackerel contains 1112.94mg of arginine per 100g serving. This is considered relatively high. If you're managing herpes, monitor your intake of high-arginine foods.
Can I eat Mackerel if I have herpes?
Yes, you can eat Mackerel. However, the key is understanding its lysine-arginine ratio (1.53) and balancing it with lysine-rich foods. Consult with a healthcare provider about your specific dietary needs.
What is the lysine-arginine ratio of Mackerel?
The lysine-arginine ratio of Mackerel is 1.53. A ratio above 1 generally favors lysine. This ratio helps determine how suitable it is for herpes management.
