4Ever Fit Lysine 500mg |
Description:
L-Lysine is an essential amino acid which cannot be manufactured in the body; hence it is important to include lysine in adequate amounts in the diet and in supplement form. Many foods supply lysine, but the richest sources by far include red meats, fish and dairy products. There is currently no official recommended dietary allowance for lysine but it is estimated that the daily requirement for an adult is approximately 12mg/kg of body weight. Like all amino acids, lysine functions as a building block for proteins.
Lysine and Herpes
A few years ago, researchers discovered that in order to grow (replicate), the herpes virus needs arginine, another common amino acid. (Foods high in arginine include chocolate, peanuts, almonds, seeds, cereal grains, gelatin, and raisins.) Lysine competes with arginine for absorption and entry into tissue cells. When lysine is present, it inhibits the growth of the herpes simplex virus (HSV) by knocking out arginine. This makes a diet high in lysine and low in arginine a useful tool in managing HSV infections. In a recent study, participants consumed large amounts of lysine (about 1 gram three times each day) while restricting food sources of arginine. A significant number of participants (74%) noticed an improvement in their HSV infections and a decrease in the number of outbreaks.
Lysine supplements (as opposed to foods high in this nutrient) can also play an important role in staving off and reducing the severity of herpes-related cold sores. Results of a six-month trial involving more than 50 people indicate that lysine is far more effective than a placebo in preventing cold sores. Participants given a placebo had more than twice as many such infections as those taking lysine. Moreover, the herpes sores that did develop in the lysine group tended to be milder, and to heal faster, than the outbreaks in the placebo group. Lysine supplements may even prevent HSV outbreaks in chronic sufferers.
The Herpes Zoster virus is responsible for chicken pox and later in life this same virus can be reactivated to present as shingles. Lysine appears to play a role in the inhibition of the herpes zoster virus in the same manner that it works against the herpes simplex virus. Keep in mind that most nutritionally oriented physicians will combine lysine therapy with conventional antiviral medications such as acyclovir or valacyclovir.
Guidelines for Use
- For a severe initial outbreak of genital herpes or shingles, see a doctor to confirm that you have the condition and be sure to take one of the prescription antiviral drugs such as acyclovir.
- Don't drink milk at the same time you take lysine.
- For canker sores: Take 1,000 mg L-lysine three times a day with meals while a canker sore is present. Reduce the dose to 500 mg three times a day for one week following healing.
- For cold sores: Take 1,000 mg L-lysine three times a day with meals for flare-ups. If you are subject to recurrent outbreaks of cold sores, continue on a maintenance dosage of 1,000 mg day.
- For shingles: Take 1,000 mg L-lysine three times a day with meals during flare-ups. Reduce the dose to 500 mg three times a day for one week after healing.
Cautions
- In very large doses (10 to 30 grams a day), lysine increases the toxicity of aminoglycoside antibiotics, such as gentamicin, neomycin, and streptomycin.
- Side effects are rare with lysine supplements, although a few cases of abdominal cramps and diarrhea have been reported with very high doses (more than 10 grams a day).
Lysine and Hair Loss
An English biotech company was recently issued a US patent for the use of L-Lysine in the treatment of various types of hair loss, including androgenic alopecia (male pattern baldness). US Patent 6136860. Applicant: Bio-Scientific Ltd., London.
" The co-administration of L-Lysine with known treatments for genetic hair loss such as minoxidil and anti-androgens results in a significant improvement in the efficacy of the treatment."
Lysine and Calcium Absorption
The presence of substantial amounts of lysine or arginine enhances intestinal Calcium absorption. As a result, some researchers believe that lysine may eventually be shown to play a role in the prevention and treatment of osteoporosis.
Lysine and Fat Metabolism
Inasmuch as carnitine is essential for the transport of fatty acyl groups into and out of the mitochondria; it is possible that severe lysine deficiency is a factor in the failure to synthesize adequate amounts of carnitine and hence to a diminished utilization of fatty acids for energy. In other words, loosing weight may be more difficult if your diet is deficient in lysine.
