L-lysine to help reduce cold sore recurrence and support skin, muscle and bone.
Regenerative support
Cold sores have a gift for timing: the wedding photos, the first day at a new job, the holiday you booked months ago.
L-lysine is an essential amino acid, which means your body cannot make it. PURICA L-Lysine helps reduce the recurrence of cold sores and helps in collagen formation. Choose vegan capsules, or an unflavoured powder with 1,500 mg in each half teaspoon.
Who it’s for
01
Cold sores
For people prone to cold sores. Taken daily, L-lysine helps reduce how often they come back.
02
Skin & collagen
For anyone looking after their skin. Lysine helps your body produce collagen, a protein important for skin, tendons and connective tissue, and supports normal tissue repair.
03
Muscle & recovery
For active people. Lysine helps build and repair body proteins, and contributes to normal muscle maintenance.
04
Bone health
For anyone minding their bones. Lysine may help your body absorb and retain calcium, and plays a role in normal bone health.


If you’re prone to cold sores, taking L-lysine regularly can help reduce how often they come back. Lysine is an essential amino acid your body gets from food. It also helps your body make collagen, a protein found in skin, tendons and other connective tissue.

How it works
Lysine works by keeping a rival amino acid in check, and by giving collagen its strength.
01
Cold sores
The virus behind cold sores needs the amino acid arginine to multiply. Lysine competes with arginine in the body, tipping the balance away from the virus.
02
Collagen
Lysine is built into collagen, where it forms the cross-links that hold its fibres together.
03
Immune response
Lysine is a building block of protein, and it helps keep your immune response strong.
Published research
In a double-blind, placebo-controlled trial, people with frequently recurring herpes simplex infections took L-lysine or a placebo for half a year. Those taking lysine came out ahead on all three measures tracked: how often outbreaks happened, how severe they were and how quickly they healed.
