About Brewers Yeast (dry)
Brewers yeast is a type of yeast that is a by-product of brewing beer. It is rich in B vitamins and protein.
Brewers yeast is used for brewing beer and can also be used as a nutritional supplement due to its rich content of B vitamins and protein.
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 many high-protein foods such as eggs, milk and cheese, fish, meat, and poultry.
Brewers yeast is a good source of lysine, an essential amino acid that is important for protein synthesis and collagen formation.
Arginine Considerations
Arginine is a semi-essential amino acid that our body can use to make nitric oxide, a molecule that improves blood circulation, cellular communication, and energy production.
Arginine has a variety of benefits for our health 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.
Brewers 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
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 inhibit the replication of the virus, while arginine can stimulate it.
Because of this, eating foods that have a high lysine-arginine ratio may help reduce the frequency and severity of herpes symptoms.
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 Brewers Yeast (dry) contains much higher levels of lysine than arginine, it is highly recommended for people who suffer from herpes, as it may prevent outbreaks.
Brewers 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.
Brewers Yeast (dry) has a high nutrient density (72.82), 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
In addition to eating foods that have a high lysine-arginine ratio, there are other dietary recommendations that can help you manage herpes outbreaks. For instance:
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.
Consider taking l-lysine supplements, which can help prevent herpes outbreaks and stop a cold sore before it emerges by limiting the availability of arginine for the virus, which it requires to produce 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.
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.
Pain, swelling, and itching can be reduced by eating foods that have anti-inflammatory, antiviral, and antibacterial properties, such as honey, plain yogurt, aloe vera, and chamomile tea. These foods can also help you heal faster by promoting tissue repair.
Is Brewers Yeast (dry) Safe for Shingles?
Yes, Brewers Yeast (dry) is an excellent choice for shingles management. With a lysine-to-arginine ratio of 1.66, 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 Brewers Yeast (dry), you're actively supporting your immune system's ability to keep VZV dormant.
Include Brewers Yeast (dry) 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 Brewers Yeast (dry) high in arginine?
Brewers Yeast (dry) contains 2740.80mg 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 Brewers Yeast (dry) if I have herpes?
Yes, you can eat Brewers Yeast (dry). However, the key is understanding its lysine-arginine ratio (1.66) and balancing it with lysine-rich foods. Consult with a healthcare provider about your specific dietary needs.
What is the lysine-arginine ratio of Brewers Yeast (dry)?
The lysine-arginine ratio of Brewers Yeast (dry) is 1.66. A ratio above 1 generally favors lysine. This ratio helps determine how suitable it is for herpes management.
