The 14 Best Canker Sore Treatments, According to Professionals

Lysine Supplement

Canker sores are a common ailment that can be painful and disruptive. Lysine is an amino acid that can help to treat canker sores. In addition, it works by inhibiting the growth of the herpes simplex virus, a common trigger of canker sores. 

Some studies have shown that lysine may also be effective in treating cold sores. In one small study, participants who applied a lysine ointment to their cold sores achieved “full resolution” in 40% of cases by day three and in 87% of cases by day six. This marks a vast improvement compared to untreated canker sore episodes, lasting up to 21 days. Lysine ointment is available for purchase online and at some drugstores. 

In addition, lysine also helps to boost the immune system, which can help to speed up the healing process. Lysine is available in supplement form and can be found in most health food stores. The recommended dosage is 500 mg three times daily. Reading the instructions carefully before using this or any other canker sore treatment is essential.
