About Nutritional Yeast
Nutritional yeast is a deactivated yeast that is used as a food product. It is a significant source of some B-complex vitamins and can be used as a replacement for cheese in many recipes.
Nutritional yeast is a popular food product used in cooking. It is known for its cheesy flavor and is often used in vegan cooking. It’s a particularly good source of lysine for people who are vegan or do not eat dairy.
Lysine Considerations
Lysine is an essential amino acid that the human system needs to build proteins. It is one of the nine amino acids that the human system cannot make by itself, so it has to come from the food we eat.
Lysine has a variety of 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.
Nutritional yeast is a good source of lysine. Lysine is an essential amino acid that is important for protein synthesis and collagen formation.
Arginine Considerations
Arginine is a essential amino acid that the human system uses to build proteins.
Arginine has different functions in the body, including wound healing, helping the kidneys remove waste products from the body, and maintaining immune and hormone function.
Arginine also plays a role in the replication of the herpes virus, making it a key factor in cold sore outbreaks. The herpes virus requires arginine to grow, replicate, and create new herpes viruses. Foods a great source of arginine, such as nuts and chocolate, may increase the frequency and severity of these outbreaks.
Nutritional yeast contains a moderate amount of arginine. Arginine is a semi-essential amino acid that is important for wound healing and immune function.
Lysine-Arginine Ratio Analysis
Lysine and arginine are two amino acids that have different roles in the body and in the herpes simplex virus infection.
The herpes simplex virus, which causes oral and genital herpes, needs arginine to multiply and infect cells.
Lysine, on the other hand, can interfere with the absorption of arginine in the intestine, and thus limit the availability of arginine for the virus.
By eating a diet higher in lysine than arginine, one may be able to prevent or treat herpes flare-ups.
Foods that have a high lysine-arginine ratio include milk and cheese, fish, poultry, fruits, and vegetables. These foods can supply the body with sufficient lysine to compete with arginine and inhibit the virus from replicating and causing flare-ups.
Because Nutritional Yeast contains much higher levels of lysine than arginine, it is highly recommended for people who suffer from herpes, as it may prevent outbreaks.
Nutritional yeast has a higher lysine to arginine ratio. This may be beneficial for individuals who are managing conditions such as cold sores or herpes, which can be affected by the balance of these two amino acids in the body.
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.
Nutritional Yeast has a high nutrient density (71.4), meaning it contains substantial amounts of both lysine and arginine. While this makes it nutrient-rich, it also means you should be more mindful of portion sizes when managing herpes. Consider consuming it in smaller, measured portions and balance it with other foods to maintain a favorable lysine-arginine ratio overall.
💡 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
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.
Make sure to drink plenty of water to keep yourself hydrated and eliminate toxins from your body. Water can also help you avoid dryness and irritation of the skin and mucous membranes, which can lead to outbreaks.
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.
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.
Try eating foods that can enhance your immune system and reduce inflammation to avoid outbreaks. Some of these foods are honey, plain yogurt, aloe vera, and chamomile tea. They can also help you with your symptoms by easing pain, swelling, and itching, and accelerating your recovery.
Is Nutritional Yeast Safe for Shingles?
Yes, Nutritional Yeast is an excellent choice for shingles management. With a lysine-to-arginine ratio of 1.80, 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 Nutritional Yeast, you're actively supporting your immune system's ability to keep VZV dormant.
Include Nutritional Yeast 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 Nutritional Yeast high in arginine?
Nutritional Yeast contains 2550.00mg 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 Nutritional Yeast if I have herpes?
Yes, you can eat Nutritional Yeast. However, the key is understanding its lysine-arginine ratio (1.80) and balancing it with lysine-rich foods. Consult with a healthcare provider about your specific dietary needs.
What is the lysine-arginine ratio of Nutritional Yeast?
The lysine-arginine ratio of Nutritional Yeast is 1.80. A ratio above 1 generally favors lysine. This ratio helps determine how suitable it is for herpes management.
