Please be aware that due to the ongoing conflict in Ukraine we are seeing shortages of Sunflower Oil. To ensure that we can still provide you our products, some of our range now uses Rapeseed Oil or Soya Bean Oil. Updates will be made to the labels and website as these products change to new formulations.

L-Lysine is an essential amino acid, meaning it can’t be synthesised in the body. It contributes to normal bone health by aiding the absorption of calcium and it plays an important role in building muscle protein. Many people take L-Lysine supplements to combat infection by the cold sore virus, Herpes simplex.

The virus requires the amino acid Arginine to replicate (reproduce) and it appears that increasing levels of L-Lysine in the body can inhibit the utilisation of Arginine & slow down viral replication, thus decreasing the number of cold sore outbreaks and speeding up healing of lesions.

The generally accepted dosage of L-Lysine for use in Herpes simplex infections is 500mg daily in between attacks and between 1g to 6g daily (1000mg to 6000mg) during an attack.
