Question 1

what is lysine?

Accepted Answer

Essential amino acid: Lysine is an esential Amino Acid (a building block for proteins) that is not synthesized in animals. We get it from aspartic acid  from plants(especially legumes) or our friendly flora (bacteria), eggs, meats, soy, cheese and fish.  It is metabolized to get acetyl-coa which is essential for production of energy & acetylcholine.  It's been pro-ported for immunodeficiency, anxiety, cancer, incr bp..

Question 2

why would   require lysine?

Accepted Answer

Can't make it: Everybody needs some lysine in their diet as an essential amino acid; especially, vegetarians need to take note. Lysine as a dietary supplement seems to slow down cold sores, and the stuff is promoted to athletes probably without any real benefit.

Question 3

can i take more than 2000 mg of lysine a day? thanks in advance.

Accepted Answer

Yes: Lysine is an essential amino acid with many benefits. Foods like beef, chicken, tuna and salmon contain 2000-4000 mg per serving. Studies where people take 3000 mg/day show no problems. Massive doses may be unsafe in those with kidney or liver disease but yes, more than 2000 mg/day is safe. See http://www.med.nyu.edu/content?ChunkIID=21791

Question 4

too much l lysine affects vision?

Accepted Answer

No effect: Lysine is a non-essential Amino Acid and the body can handle it well.  The eye takes in what it needs and leaves the rest in the blood stream. No sure why you would over-indulge in lysine but any changes in your eyesight are from some other cause.

Question 5

using lysine while breastfeeding? yes, no? why not?

Accepted Answer

Yes: Lysine is an essential amino acid usually found in a normal diet. As a doctor, I am not aware of any recommendations to breast feeding woman that they require extra lysine, in fact, I have never prescribed it. You should just get it from a proper well balanced diet and then it will pass through the breast milk so that your baby can have some too.

Question 6

what's the role of lysine in preventing infections?

Accepted Answer

Herpes: Lysine appears to interfere with herpes virus metabolism of arginine, so its use in infections is to reduce herpes flares (both cold sores as well as genital herpes).

Question 7

how many l lysine a day?

Accepted Answer

L (levo) lysine...: ...is a natural amino acid, present in greater or lesser amounts in all proteins. Sold as a health supplement, but there are no proved benefits. Sometimes recommended by some non-scientific sources for herpes, but lysine has no benefit in treating or preventing herpes outbreaks. The dose probably doesn't matter much; take whatever the label says. It would be difficult to take enough to be harmful.

Question 8

what's the ld50 of lysine?

Accepted Answer

Unmeasurable: Lysine is an essential Amino Acid that many people take in generous amounts to control fever blisters. It probably cannot kill you, so there is no ld50.

Question 9

Accepted Answer

Lysine: Used for healing & preventing recurrences of cold sores (herpes simplex labialis). There is not enough evidence for using it to improve athletic performance. No evidence that it helps anxiety.

Question 10
