Canker sores are not contagious Unlike cold sores, canker sores are not contagious. Canker sores start happening from a young age If you are susceptible to canker sores, you probably started getting them as a child. Canker sores start off mild and then gradually get worse A canker sore starts out as a little ulcer with mild discomfort and then goes through an ulcerative stage. The pain and discomfort will peak at about the one-week mark.
The duration of the pain and discomfort can extend for two to three weeks. A canker sore can be very painful depending on how deep it is and how many there are. Some people will get a single lesion and sometimes there will be multiple lesions.
Canker sores are not caused by a bacteria or virus The cause of canker sores is unknown. However, some studies say that they may occur as an allergy to specific strains of bacteria. You want to avoid palliative treatments, such as gels and creams. Make sure to read the label before you purchase any supplement. Look for supplements that have been quality tested by a third party.
Lysine is an important amino acid that can be found in high-protein foods like meat, nuts, beans, and eggs. It is also available as an oral supplement or topical ointment. Some research suggests that lysine may be helpful for treating certain conditions, such as cold sores and anxiety.
Before taking lysine, talk to your doctor about dosage and use. Some studies have shown that lysine has a small impact on glucose levels. Lysine is consumed naturally in meat beef, pork, poultry , cheese, certain fish, eggs, beans, legumes, and dairy products. Most people get enough lysine in their diets, but those who do not may experience fatigue, nausea, dizziness, loss of appetite, agitation, bloodshot eyes, anemia, and reproductive challenges.

Cold sores , or fever blisters , result from a viral infection. These painful, fluid-filled blisters commonly appear on or near the lips in clusters or patches. Cold sores are caused by the herpes simplex virus type 1 HSV-1, also known as oral herpes.
HSV-1 can be spread through close contact, such as kissing. There is no cure for a cold sore infection, but this condition can be treated with common antiviral medication , such as valacyclovir Valtrex or acyclovir Zovirax. A medication you might take in addition to antivirals is lysine, an essential amino acid found in protein. Lysine is essential for human health, aiding calcium absorption and collagen formation. Many people consume enough lysine in their diet. But some — athletes or vegans specifically — may need to consume more.
In order to replicate in the body, herpes simplex needs a steady source of arginine. This amino acid converts into nitric oxide within your body, a chemical necessary to expand blood vessels and improve blood flow. Lysine is thought to interfere with arginine being absorbed into your intestine , making the amino acid unavailable for the virus.
So even if it may not cure a cold sore infection, lysine can help slow or prevent the HSV-1 replication process. In addition, older research suggests that lysine may reduce the number of occurrences of this infection and decrease healing time. For example, a small study from showed that lysine sped up the healing process for 87 percent of participants, shortening the average time from 21 days to 6 days for these people. To treat a cold sore infection, apply lysine cream to the affected area every two hours for 11 days.
To manage cold sore infections, the recommended dosage for oral supplements is 1 gram three times daily.
