L-Lysine is an essential amino acid, meaning the body needs it but cannot manufacture it so you must consume enough in your diet or in a supplement. The best food sources are red meat, fish, dairy, eggs, beans, and legumes. By competing with L-Arginine, another amino acid, L-Lysine helps counteract the Herpes virus that causes cold sores when the immune system is weakened. Fatigue, overwork, intense exercise, and emotional problems can all create the stress that weakens the immune system and brings the Herpes virus out of hiding. It invades target cells and replicates, creating the blisters known as cold sores. As it is difficult to achieve therapeutic levels of L-Lysine from dietary sources alone, supplementation is the most effective tool to inhibit the replication of the Herpes virus and reduce the severity and duration of outbreaks.

Product Highlights

  • Can be taken at the first sign of a Herpes outbreak to stop it from progressing or preventively if outbreaks are frequent
  • L-Arginine supports replication of the Herpes virus and should be avoided during an outbreak, along with food sources such as chocolate, peanuts, almonds, and raisins
  • L-Lysine supports production of L-Carnitine which is important throughout the body including the cardiovascular system, energy production, and the breakdown of fats
  • L-Carnitine is vital to healthy heart and brain function (especially in older people) as well as liver health and male fertility
  • Just one capsule per day of L-Lysine may aid calcium absorption and support the formation of collagen, which is important for bone and joint health

I have tried other L-Lysine supplements, but none compare to Sisu. I am happy to have finally found a product that actually works.

As someone who gets frequent cold sores, I can't recommend Sisu L-Lysine enough. It has made a significant difference in my quality of life.

My mom recommended Sisu L-Lysine to me and I am so glad she did. Not only has it reduced my cold sore outbreaks, but it has also improved my overall health.
