FAQs

What is L-lysine used for?

L-lysine is used to support immune function, promote collagen synthesis for skin health, and aid in calcium absorption for bone strength. It's also taken as a supplement to help prevent and manage cold sores caused by the herpes simplex virus.

Is it okay to take L-lysine every day?

Yes, it's generally safe to take L-lysine supplements daily, especially for individuals with specific health concerns like cold sores or those with dietary deficiencies. However, it's essential to follow recommended dosages and consult with a healthcare professional, especially if you have underlying health conditions.

What is the difference between lysine and L-lysine?

Lysine, an essential amino acid, exists in two forms: L-lysine and D-lysine. L-lysine is the biologically active form found in proteins and used by the body. D-lysine, a mirror image of L-lysine, is not utilised in the same way and is less common in nature.

Does lysine actually help cold sores?

Yes, lysine supplementation has been shown to help prevent and reduce the frequency, severity, and duration of cold sores caused by the herpes virus. Lysine competes with another amino acid, arginine, which the virus requires for replication, thereby inhibiting viral growth and recurrence.
