About Ginger Beer
Ginger beer is a sweetened and carbonated, usually non-alcoholic beverage. It is produced by the natural fermentation of prepared ginger spice, yeast, and sugar.
Most commercial ginger beers are non-alcoholic sodas with strong ginger flavor and high sugar content. While ginger itself is anti-inflammatory, the high sugar load in commercial brands outweighs this benefit.
Lysine Considerations
Lysine is an important amino acid that the body needs to build proteins. It is one of the nine amino acids that your 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.
Ginger beer contains 0mg of lysine. It is not a source of protein.
Arginine Considerations
Arginine is a semi-essential amino acid that our body can use to make nitric oxide, a compound that improves blood circulation, cellular communication, and energy production.
Arginine has different benefits for our wellbeing and performance, such as lowering blood pressure, enhancing wound healing, and increasing exercise endurance.
Arginine can also affect the herpes virus, which causes cold sores and genital herpes. Studies suggest that arginine may help the virus grow and cause outbreaks, so people with herpes may want to avoid foods that are high in arginine or take lysine supplements to block its effects.
Ginger beer contains 0mg of arginine. Any trace arginine from actual ginger root is negligible in the final processed drink.
Lysine-Arginine Ratio Analysis
A food's lysine-arginine ratio indicates how much of these two amino acids it contains. Both lysine and arginine are important for protein synthesis and other bodily functions.
The two compounds can affect the herpes simplex virus, which is responsible for cold sores and genital herpes, in opposite ways. Lysine can stunt the virus from reproducing, while arginine can help it propagate.
Eating foods with a high lysine-arginine ratio could help relieve the appearance and severity of herpes outbreaks.
Some foods that have a high lysine-arginine ratio are dairy, fish, poultry, fruits, and vegetables.
These foods can give the body enough lysine to prevent the virus from taking up arginine, and thus stop its growth and spread.
Because Ginger Beer contains much higher levels of arginine than lysine, limiting its consumption is recommended by people who suffer from herpes, as it may trigger outbreaks.
The lysine-arginine ratio is neutral. However, the high sugar content (often 30g+ per bottle) can be inflammatory. If consuming for the benefits of ginger, raw ginger tea or ginger extract is a much better choice than sugary soda.
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.
Ginger Beer has a low nutrient density (0), 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
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:
A diverse and nutritious diet that supports your immune system and fights inflammation is essential. This means you should eat lots of fruits, vegetables, whole grains, lean protein, and healthy fats, and steer clear of processed foods, added sugars, alcohol, and caffeine, which can harm your health.
Stay well hydrated throughout the day. Dehydration stresses the body and can raise cortisol levels, which is a documented trigger for HSV reactivation. Aim for at least 1.5–2 litres of water daily, and compensate with extra fluid intake after exercise, in hot weather, or when consuming diuretics like coffee or alcohol.
L-lysine supplements can help you prevent herpes outbreaks and stop a cold sore before it develops by depriving the virus of arginine, which it needs to form 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.
Your immune system can be weakened and inflammation can be increased by foods that can cause allergic reactions or sensitivities, such as gluten, dairy, nuts, eggs, or shellfish. Avoid these foods to prevent 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 Ginger Beer Safe for Shingles?
Caution is strongly advised. While the lysine-arginine ratio of Ginger Beer might look neutral, alcohol is a known immune system suppressant.
Shingles outbreaks occur when the immune system is weakened, allowing the Varicella-Zoster virus to reactivate. Consuming alcohol—regardless of its amino acid content—can impede your white blood cells' ability to fight the virus, potentially prolonging the outbreak or increasing severity.
Recommendation: It is best to avoid or strictly limit alcohol during an active outbreak or recovery.
⚠ Immune Suppressant: Alcohol weakens the immune defense needed to keep the shingles virus dormant. Read more about Alcohol and Viral Outbreaks here.

Is Ginger Beer good or bad for herpes?
With a ratio of 0.00, Ginger Beer is arginine-dominant. People managing herpes should be mindful of portion sizes. The lysine-to-arginine ratio is the key metric: foods above 1.0 generally support herpes management, while foods below 1.0 require more careful portioning. Ginger Beer fits into the cautious category.
Is Ginger Beer high in arginine?
Ginger Beer is relatively low in arginine at 0.00mg per 100g. This level is manageable for most people when consumed as part of a balanced, lysine-rich diet.
How much lysine does Ginger Beer contain?
Its lysine content of 0.00mg per 100g is low, so it contributes little lysine to counterbalance arginine from other foods. Because its arginine content exceeds its lysine content, you may want to pair Ginger Beer with higher-lysine foods to maintain a favourable overall balance.
Can I eat Ginger Beer if I have herpes?
Ginger Beer has a ratio of 0.00, meaning arginine is more abundant than lysine. You can still include it in your diet, but be mindful of portion size — especially during periods of stress or if you feel a prodrome coming on. Always consult your healthcare provider for personalised advice.
What is the lysine-arginine ratio of Ginger Beer?
The lysine-arginine ratio of Ginger Beer is 0.00, calculated from 0.00mg lysine and 0.00mg arginine per 100g serving. A ratio below 1 means arginine is more abundant, which requires more careful intake management.
Does Ginger Beer trigger cold sores?
Ginger Beer could potentially contribute to cold sore triggers if eaten in large quantities, due to its arginine-dominant profile (ratio: 0.00). That said, cold sore triggers are cumulative — a single food rarely causes an outbreak. The overall diet pattern, stress levels, sun exposure, and immune status all play a role. If you notice a personal correlation between eating Ginger Beer and outbreaks, consider reducing your serving size.
