Best L-Lysine Supplements

L-Lysine is an essential amino acid that plays a key role in the production of several important proteins, enzymes, and antibodies in the body.

It's also commonly used as a dietary supplement for its potential health benefits.

Unfortunately, our bodies can't produce L-Lysine on their own, so we must get it from our diet or supplements.

This is where L-Lysine supplements come in handy, especially for those who may not get enough of this essential amino acid from their diet.

One of the key benefits of L-Lysine is its potential to manage herpes outbreaks and prevent cold sores.

Cold sores, or fever blisters, result from a viral infection caused by the herpes simplex virus type 1 (HSV-1).

This virus can be spread through close contact, such as kissing.

How L-Lysine Helps Manage Herpes Outbreaks and Prevent Cold Sores

In order to replicate in the body, herpes simplex needs a steady source of arginine, another amino acid.

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.

Research suggests that lysine may reduce the number of occurrences of this infection and decrease healing time.

For example, a small study from 2005 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.
