L-lysine to help reduce cold sore recurrence and support skin, muscle and bone.

Purica L-Lysine powder, 300 g bottle

PURICA L-Lysine · Made in Canada.

Regenerative support

Essential, in Every Sense.

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

Muscle & recovery

Recover and rebuild

For active people. Lysine helps build and repair body proteins, and contributes to normal muscle maintenance.

Bone health

Hold on to calcium

How it works

Tipping the Balance.

Lysine works by keeping a rival amino acid in check, and by giving collagen its strength.

01

Cold sores

Keeps arginine in check

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

The strength in collagen

Lysine is built into collagen, where it forms the cross-links that hold its fibres together.

03

Immune response

Part of a strong defence

Lysine is a building block of protein, and it helps keep your immune response strong.

Published research

Six Months, Measured.

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.
