How Is Herpes Simplex Diagnosed
Healthcare providers may diagnose herpes simplex based on how the sores look. Your provider may take a sample from the sore. Laboratory analysis of the sample can confirm or rule out the herpes virus.
If you dont have sores, your healthcare provider can use a blood test to check for HSV-1 and HSV-2 antibody, a marker showing youve been exposed to the virus. The blood test doesnt show an active infection . But it informs your provider whether youve been exposed to the herpes virus in the past. If this is your first infection, you may not test positive for herpes if there hasnt been enough time for your body to develop antibodies. The HSV-1and HSV-2 antibody test may be repeated in eight to 12 weeks.

What Is Cat Flu
Cat flu is an upper respiratory tract infection that causes cold-like symptoms in cats. It is usually caused by the feline herpes virus or feline calicivirus, both of which are highly contagious. Lets focus on the herpes virus, as lysine is typically used when the herpes virus is involved.
Symptoms of cat flu caused by the herpes virus include:
- Severe eye infections and discharge, known as conjunctivitis
- Eye ulceration: ulceration of the clear layer in front of the iris and pupil, called the cornea
- Sneezing and a discharge from the nose
Its also common for cats with cat flu to develop a bacterial infection as well since the immune system is overwhelmed.
Once cats have the herpes virus, most become carriers. This means that, although they may not show any symptoms, they still have the virus in their body and may pass it on to other cats. It also means they may have a flare-up of symptoms when they are run down or stressed.

What Are The Symptoms Of Herpes
The hallmark of HSV infection is a blister or cluster of blisters that often feels tingly and itchy at first, becoming sore later, eventually crusting over and disappearing. An initial episode of herpes may produce fever, malaise, and enlargement of local lymph nodes recurrences are usually milder but may begin with a brief period of general malaise. Once you get infected, the virus is with you for life. It lives in nerve cells where the immune system cannot find it, becoming re-activated from time to time. Common triggers of herpes outbreaks are colds and other viral infections, fatigue, sun exposure, physical irritation of the skin, and emotional stress. Some people are bothered by outbreaks once a year or less, while others may get them every few weeks.

Lysine Acid Interactions And Combinations
One possible lysine interaction is with arginine. Arginine and lysine share common pathways in the body. High levels of arginine may lower lysine levels in the body.
Another possible lysine interaction is with aminoglycoside antibiotics . Taken with lysine it may increase the risk of nephrotoxicity, which is a poisonous effect on the kidneys. Please consult your doctor or pharmacist before taking any form of lysine supplements, if you are taking antibiotics.
Estimating How Much Lysine To Prevent Herpes Outbreaks
The commonly recommended dosage of lysine to prevent herpes outbreaks is 1,000 mg three times a day. The idea is to constantly provide your body with a supply of lysine so that you dont have peaks of high lysine and then nothing until you take it again the next day.
Whether or not this dose will be effective for you is based on what kind of diet you eat and what your bodys need for lysine is. If you eat meat, dairy and eggs, you probably will need less lysine than a vegan who consumes lots of nuts and seeds. This is because animal products have a lot of lysine whereas the nuts and seeds eaten by vegans typically have high levels of arginine. Vegans have a rather difficult time keeping their lysine numbers high, so their doses are likely going to be considerably higher than that of a meat eater.
So, to estimate your dosage of lysine, have a look at the values you calculated and see if your diet is high in lysine, moderate in lysine, or low in lysine compared to arginine. If you are moderate in lysine, try starting with the 1,000 mg three times per day. If you are high in lysine, try 1,000 mg twice a day. If you are low in lysine, try 1,000 mg four times a day.
If you find that you are still experiencing outbreaks, try upping the frequency of your dosage or try a higher dose.

How Do I Use Lysine For Cold Sores
Lysine for cold sores is a known and effective treatment for many who suffer from open sores on the lips and genitals caused by the herpes simplex virus . L-lysine, the biologically active form, is available in pharmacies, grocery stores, or specialty vitamin retailers in capsules from 500 to 1,000 mg. Excess lysine is excreted through urine, so it does not accumulate in the body. Effective dosages range from 1,000 mg up to 3,000 mg per day during an active outbreak. Lysine should not be taken with food.
HSV is acquired through contact with carriers of the virus by the exchange of body fluids such as may occur during kissing, coughing, unprotected sex, or touching open cuts. HSV is very common. Many asymptomatic people are carriers and spread the virus unknowingly. Upon infection, people will harbor the virus for the rest of their lives. The virus will lie dormant between outbreaks, at which time the carrier will become contagious.
Lysine for cold sores has been observed to dramatically decrease the frequency of outbreaks. Outbreaks are often triggered by some form of stress. Stress can take the form of ultraviolet light, colds, or other infections, or the anxieties of daily activities. Lysine deficiency is rare, since it is found in many proteins. Vegans using grain as their sole source of protein may need to take lysine supplements.
May Support Healthy Muscles
Because lysine plays a role in cell turnover and growth, researchers believe it may support healthy muscle mass and strength. One study found that over 8 weeks, a high lysine diet had a small positive effect on increasing the participants muscle strength .
Another study found that adequate lysine, calcium, and vitamin D levels are essential for muscle mass, bone health, and lower body fat mass for young adult women . Vitamin D deficiency: symptoms, treatment, and prevention
