Inhibits the Growth of Viruses*

  • Inhibits the growth of viruses.
  • Used in the treatment of herpes simplex virus.
  • Produces L-Carnitine which improves stress tolerance and fat metabolism and has an anti-fatigue effect.
  • Promotes bone growth by helping to form collagen, the fibrous protein which makes up bone, cartilage and other connective tissue..
  • Aids in the absorption of calcium.

What does it do?

Lysine is an essential amino acid needed for growth and to help maintain nitrogen balance in the body. Essential amino acids cannot be made in the body and must be supplied by the diet or supplements. Lysine appears to help the body absorb and conserve calcium.1 Linus Pauling believed that lysine helps maintain healthy blood vessels, an idea based on biochemistry and results from three people with angina pectoris who responded to lysine supplementation.2 3

Lysine has many functions in the body because it is incorporated into many proteins, each of which is used by the body for a variety of purposes. Lysine interferes with replication of herpes viruses and is therefore often prescribed by nutritionally oriented doctors to people with cold sores or genital herpes. A review of the research trials investigating the effects of lysine on people with cold sores shows that most though not all trials support the use of lysine.4


L-Lysine is an essential amino acid, which means your body cannot manufacture it. It must be obtained through the diet or by supplementation. Lysine is one of the most well known amino acids and is an essential component of all proteins.*

L-Lysine is  an essential amino acid. One  hard  gelatin  capsule  supplies 500 mg of free form, crystalline pure. L-Lysine is an essential amino acid and although it is essential, it is not produced in our bodies. L-Lysine is also lacking in  many  if  not  most vegetables and grains, so eating a proper diet does not insure an adequate supply.

Besides being essential for normal  bodily  function, L-Lysine has been shown to effectively suppress the Herpes Simplex virus (the one that causes cold sores and mouth ulcers, etc.) Lysine is incorporated into the virus mistakenly as the virus tries to take in the similarly structured compound, arginine, which promotes Herpes Simplex growth. Without adequate arginine, the virus cannot duplicate. Vitamin C and lysine in combination may inhibit other viruses similar to the Herpes virus such as Herpes zoster, Ruebella, Varicella, Varioula, Adenovirus types I and II and Cytomegalovirus.1 

An important function of lysine is to regulate absorption of calcium and maintaining the nitrogen balance in the body. It is needed for forming collagen, the protein that forms the matrix of bone, cartilage, and connective tissue. Vitamin C controls the conversion of lysine into the collagen constituent.

Even more exciting L-Lysine has been shown to reduce Lipoprotein a (Lp (a)) and protect against heart disease when dosed in conjunction with vitamin C. Let's look at what the most famous contemporary scientist had to say about L-Lysine after extensive research.

Lysine is involved in the production of antibodies, hormones, and enzymes for tissue repair. For this reason it is used for surgical recovery and sports injuries. Working as a precursor to citrulline and carnitine, lysine can lower high triglyceride levels.

Lysine has also been used to treat osteoporosis, marasmus, atherosclerosis, migraine headaches, Bell's palsy, and Meniere's disease. Preliminary research shows lysine to be effective for relieving angina when taken in conjunction with Vitamin C.

Lysine deficiency results in loss of energy, concentration lapse, irritability, bloodshot eyes, loss of hair, anemia, growth retardation, and reproductive disorders. In studies on rats, an equivalent human dose of 140g of lysine has been associated with increased toxicity of aminoglycoside antibiotics.

- Q & A -


Where is it found?

Brewer’s yeast, legumes, dairy, wheat germ, fish, and meat all contain significant amounts of lysine.

Who is likely to be deficient?

Most people, including vegans (vegetarians who also avoid dairy and eggs), consume adequate amounts of lysine. Athletes involved in frequent vigorous exercise have increased need for essential amino acids, although most diets meet these increased needs. The essential amino acid requirements of burn patients may exceed the amount of lysine in the diet.

How much is usually taken?

Most people do not require lysine supplementation. Nutritionally oriented doctors often suggest that people with recurrent herpes simplex infections take 1,000–3,000 mg of lysine per day.

Are there any side effects or interactions?

In animals, high doses of lysine have been linked to increased risk of gallstones5 and .6 At supplemental doses, no consistent problems have been reported in humans, though abdominal cramps and transient diarrhea have occasionally been reported at very high (15-40 grams per day) intakes.7

Lysine supplementation increases the absorption of calcium and may reduce its excretion.8 As a result, some researchers believe that lysine may eventually be shown to have a role in the prevention and treatment of osteoporosis.9

Lysine works with other essential amino acids to maintain growth, lean body mass, and the body’s store of nitroge

At the time of writing, there were no well-known drug interactions with lysine.
