Question 1

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 2

are there any side effects of l-lysine?

Accepted Answer

High doses, maybe: Deficiency symptoms might include stomach cramps, diarrhea, hair loss weight loss, poor concentration, reproductive problems, kidney stones. It can interact with a number of antibiotics to lethal effect.  It could cause severe allergic reactions, (swelling of lips and tongue, or throat closure, difficulty breathing) old people need it more than young.  Athletes use it.

Question 3

do l-lysine works for herpes?

Accepted Answer

Maybe, but uproven: There are some non-medical "treatments" such as lysine that may lower the frequency of outbreaks, and some over-the-counter medications that can help with healing of cold sores. There are usually only a handful of research studies on each product, which doesn't mean much in the medical world. A patient can collect information and visit his doctor to see if any of the "treatments" are worth trying.

Question 4

can l-lysine prevent miscarriages?

Accepted Answer

Not to my knowledge: Highly unlikely

double check with your doc also.

Question 5

is l-lysine safe to take during pregnancy?

Accepted Answer

Probably- moderation: As is usually the case, no research has been done so no one knows for sure. However, lysine occurs naturally in many foods so every woman who has ever been pregnant has consumed lysine in their diet. Thus, it is certainly safe in moderation. The only possible concern is high doses may lower levels of arginine, another amino acid. Doses up to 1500 mg/day are probably safe.

Question 6

can i use aciclovir and l-lysine together.

Accepted Answer

Yes: Both Acyclovir (it's cousin valcylovir or valtrex) and the Amino Acid l-lysine are all common treatments for cold sores and should be safe to use together. Follow the directions of your doctor or the bottle's label.

Question 7

is it ok to take l lysine with amoxicillin?

Accepted Answer

Yes: Wise to ask to be sure.
L-Lysine is a very benign substance, an amino acid that we get in our diet every day. It's not known to interact with pharmaceuticals except one type- aminoglycoside antibiotics like gentamycin.
But it's perfectly safe to take Lysine with Amoxicillin.
It's also wise to take probiotics, esp. Sacchromyces boulardii.

Question 8

l-lysine ok when pregnant to fight sickness?

Accepted Answer

Best not: According to the natural medicines comprehensive database on complementary and alternative medicines, insufficient data are available on use in pregnancy, thus use should be avoided.

Question 9

should i be taking l-lysine if i do not have a deficiency in it?

Accepted Answer

Not necessary.: In the United States, supplementation with L lysine is not necessary, since plenty is present in the diet. The preponderance of studies do not show benefit to taking supplemental L-lysine.  You can save your money. Good luck.

Question 10

why do i have to stop taking l-lysine, vitd3, and ultra mag a week before my surgery?

Accepted Answer

Check with provider: Often the surgeon recommendation is to stop supplements before a surgery in order to reduce any adverse events.  Sometimes there is a worry about drug to supplement interactions.  If you feel you need these during surgery then ask you provider for the specific reason not to take them and you might work out a solution
