Lysine

Lysine (also known as L-lysine) is an essential amino acid,
meaning it can’t be produced by the body and must be obtained
through the diet. It may also be taken as a nutritional
supplement.

LYSINE IS:

• The precursor for carnitine synthesis (a non-essential amino
  acid required for using fats for energy)
• A structural protein in some hormones
• A linkage for vitamin B6 on many enzymes 
• A component of collagen – a structural protein found throughout
  the body. 

HEALTH BENEFITS

• Decreases the frequency, severity and healing time of cold
  sores. Although some studies have contradicted these findings, it’s
  possible that only doses over 1000 mg per day have an anti-herpes
  virus effect. 
• Improved calcium absorption Lysine may also increase bone
  density by stimulating the activity of bone-forming
  cells. 
• May stimulate the release of human growth hormone, when
  combined with arginine. Growth hormone boosts metabolic function,
  which increases the rate at which fat is burnt for energy. Growth
  hormone also has an anabolic effect, promoting protein formation
  and tissue growth.
