L-lysine has been shown to help prevent cold sores and the herpes virus. But what is L-lysine and how does it work?
L-lysine is an essential amino acid. Lots of amino acids are found in nature but there’s only a small number that are responsible for protein creation and an even smaller number can be created in the body itself. L-lysine cannot be created through the body therefore, needs to be supplemented through diet.
Amino acid deficiencies, like L-lysine, can cause deterioration of internal cells. This can lead to ill health and disease so it’s crucial to ensure the correct intake in the diet.
Research has shown that L-lysine is very effective in minimising the onset of cold sores and helps lessen the recovery time of an outbreak*1.
The reason why this nutrient fights cold sores is not certain, but one such reason may be the way that it interacts with arginine, another amino acid that is produced in small amounts within the body.
Arginine has been shown to increase the replication rate of herpes virus cells, and high amounts of L-lysine in the body decrease the activity of arginine because they work against one another.
Another study showed that L-lysine intake when feeling the on-set of a cold sore found individuals will be less likely to experience an outbreak and the lesions will be fewer and less severe*2.
A study published in the journal Alternative Medicine Review found that L-lysine helps to cure and treat cold sores naturally. The study showed that within 3 days, L-lysine completely cured the symptoms of cold sores in 40% of the participants. Nearly 90% found that within 6 days they no longer had any cold sores*3.
Sona has several L-lysine vitamins appropriate for use when cold sores occur.
Sona Lysinel is a tablet containing 500mg of active L-Lysine. Each pack contains a strong, 5 day course.
At the first sign of a cold sore take two tablets three times daily, for 3 consecutive days with meals and one tablet a day thereafter to prevent recurrence. See our products page for more information.
