About Cold Brew Coffee
Cold brew coffee is made by steeping coarsely ground coffee beans in cold water for an extended period, typically 12-24 hours. This method results in a smooth, less acidic coffee with a rich flavor profile.
Cold brew coffee is low in calories and high in caffeine, providing a refreshing and energizing drink. It contains antioxidants and compounds that may offer health benefits, including anti-inflammatory properties. Regular consumption can improve mood and alertness.
Lysine Considerations
Lysine, a essential amino acid, is required by the body to synthesize proteins and bolster the immune system.
Lysine has the potential to prevent or treat cold sores, which are blisters caused by the HSV-1 virus, also known as herpes.
Lysine operates by stunting the proliferation of HSV-1, which relies on another amino acid, arginine, to reproduce and infect cells. Lysine can only be acquired through our diet and is present in different high-protein foods such as eggs, milk and cheese, fish, meat, and poultry.
Cold brew coffee is not a source of lysine, providing only 1 mg of lysine per 100 g of beverage. Lysine is essential for various bodily functions, and a deficiency may lead to health issues such as fatigue and weakened immunity.
Arginine Considerations
Arginine is an amino acid that our body needs to make nitric oxide, a molecule that helps with blood circulation, energy, and communication between cells.
Arginine can benefit your 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.
Cold brew coffee contains approximately 6 mg of arginine per 100 g, which is relatively low. Arginine is involved in nitric oxide production and may support cardiovascular health.
Lysine-Arginine Ratio Analysis
The ratio of lysine to arginine in a food item indicates the amount of these amino acids it contains. Lysine and arginine are both necessary for protein synthesis and other metabolic processes.
However, they have different effects on the herpes simplex virus, which causes cold sores and genital herpes. Lysine can stunt the replication of the virus, while arginine can stimulate it.
Eating foods with a higher lysine-arginine ratio may help relieve the occurrence and severity of herpes outbreaks.
Examples of foods with a high lysine-arginine ratio include dairy, fish, poultry, fruits, and vegetables. These foods can provide the body with enough lysine to compete with arginine, potentially reducing the risk of viral replication.
Because Cold Brew Coffee contains much higher levels of arginine than lysine, limiting its consumption is recommended by people who suffer from herpes, as it may trigger outbreaks.
Cold brew coffee has a low lysine-arginine ratio of 0.17, indicating a higher arginine concentration. This may not be ideal for individuals with HSV infections, as arginine can trigger outbreaks. Those with HSV may want to limit cold brew intake and increase lysine-rich foods.
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.
Cold Brew Coffee has a low nutrient density (0.07), which means it contains relatively lower amounts of these amino acids. You can safely enjoy larger portions of this food without worrying as much about amino acid balance, making it a flexible option in your herpes management diet.
💡 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
Coffee is rich in antioxidants but also contains caffeine, which can lead to increased stress levels.
High consumption of coffee can potentially weaken the immune system and make you more susceptible to herpes outbreaks.
It is advised to limit coffee consumption, especially for those with herpes.
Practical Recommendations
Besides consuming foods with a high ratio of lysine to arginine, you should also follow some other dietary tips to cope with herpes outbreaks. For example:
A well-balanced and healthy diet that strengthens your immune system and lowers inflammation is important. This means you should eat a lot of fruits, vegetables, whole grains, lean protein, and good fats, and avoid 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.
Other food supplements, such as vitamin C, zinc, selenium, and antioxidants, can help you boost your immunity and protect your cells from oxidative stress.
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.
Foods that can boost your immunity and fight inflammation are essential to prevent outbreaks. Honey, plain yogurt, aloe vera, and chamomile tea are some examples of these foods. They can also soothe your symptoms and help you recover quicker by reducing pain, swelling, and itching.
Is Cold Brew Coffee Safe for Shingles?
Consume with caution. The concern with Cold Brew Coffee extends beyond its lysine-arginine ratio (0.17).
High levels of caffeine stimulate the production of cortisol, the body's primary stress hormone. Elevated stress and cortisol levels are among the most common triggers for Shingles (and Herpes) reactivation. If Cold Brew Coffee makes you jittery or affects your sleep, it can weaken your immune defense.
⚡ Stress Trigger: Caffeine can mimic stress in the body. If you are prone to stress-induced outbreaks, consider decaf or herbal alternatives.

Is Cold Brew Coffee high in arginine?
Cold Brew Coffee contains 6.00mg of arginine per 100g serving. This is a moderate amount. If you're managing herpes, monitor your intake of high-arginine foods.
Can I eat Cold Brew Coffee if I have herpes?
Yes, you can eat Cold Brew Coffee. However, the key is understanding its lysine-arginine ratio (0.17) and balancing it with lysine-rich foods. Consult with a healthcare provider about your specific dietary needs.
What is the lysine-arginine ratio of Cold Brew Coffee?
The lysine-arginine ratio of Cold Brew Coffee is 0.17. A ratio below 1 means arginine is more abundant. This ratio helps determine how suitable it is for herpes management.
