Lysine is an essential amino acid needed for growth and to help maintain nitrogen balance in the body. As an essential amino acid, it is not made in the body and must be supplied by the diet. Brewer’s yeast, pulses, beef, lamb, chicken, beans, eggs, dairy and fish contain significant amounts of lysine.
What it does
- Herpes Prevention and Treatment: Lysine acts against arginine, which is known to promote the growth of the herpes virus. The best preventative results may be obtained when lysine is combined with vitamin C, zinc, and a diet that promotes an increase in the lysine to arginine ratio.
- Cardiovascular Protectant: Lysine has been reported to strengthen the integrity of the tissue in the artery walls, thereby inhibiting the formation of arterial lesions and/or speed their healing. Lysine is also a precursor of carnitine, a potent cardiovascular tonic.
- Bone Health: Lysine supplementation increases the absorption of calcium and may reduce its excretion, whereas lysine deficiency is associated with increased excretion of calcium in the urine.
- Lead Detoxification: Lysine has been shown to bond to the heavy metal lead, effectively reducing its toxicity and aiding its removal from the body.
All amino acid supplements are best taken on an empty stomach.
