Do L-lysine tablets work for fever blisters.

Do L-lysine tablets work for fever blisters.

Nope, no effect: D-Lysine has absolutely no benefit in people with either oral or genital herpes. Do not believe the many misleading claims you can find online and don't waste your money. Acyclovir and related drugs effectively treat outbreaks (it only takes a single dose); if frequent, daily drug can prevent them. Use a strong sunblock if you find sun exposure triggers outbreaks. ...Read more

Do L-lysine tablets work for fever blisters. I have used them and they worked for me and a few of my friends. You need to take up to 12 in a day but?

Not herpes: In your message after my rearlier reply, you said your fever blisters clear within a day of taking lysine. That means it wasn't a fever blister (oral herpes). Once a vesicle (blister) appears, no HSV outbreak can heal so fast. Effective treatment (e.g. valacyclovir) shortens average duration from 10 days to 7. Search online for photos of typical oral herpes. Lysine doesn't work for true herpes. ...Read more

I have fever blisters in my nose. I'm taking aciclovir and lysine. I feel like the sores are spreading into my sinuses. Not sure what else I can do?

I have fever blisters in my nose. I'm taking aciclovir and lysine. I feel like the sores are spreading into my sinuses. Not sure what else I can do?

Get it seen by a doc: Any blister on the nose should be evaluated by a physician, to assess for shingles (varicella). Called hutchinson's sign, it can signal an ophthalmic herpes zoster eruption, which can render you blind. The reason for this is that the nerve tips on the nose share the nerve that also branches out as the ophthalmic nerve to the eye. ...Read more

How many l lysine a day?

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. ...Read more

I'm 6 weeks pregnant please help! Is it ok to take 500 mg of l-lysine with my prenatals?

Category C: That Amino Acid is category c meaning it should only be taken if the benefits outweigh the risks. The only potential use I can think as to why you might want to take this is for herpes prevention. I would use safe, approved herpes medications like Valtrex (valacyclovir) or Acyclovir before using unproven herbal remedies in the early first trimester of pregnancy. ...Read more

Can melatonin, gama, l-arginine, l-lysine and gluta increase HGH production after 19 in females?

Can melatonin, gama, l-arginine, l-lysine and gluta increase HGH production after 19 in females?

Yes, but not by much: Human growth hormone can be stimulated by a number of ways, but the stimulation will not significantly increase the daily 24hr amount in any given person. Put another way, one may produce a spirt of hgh by taking l-arginine but the additional amount is just a drop in the bucket when compared to the 24hr amount of hgh that the body make. The best way to increase hgh levels is by DX and rx. ...Read more

Do L-Arginine, L-Ornithine and L-Lysine tablets stunt growth in a 15 year old? Is stacking them just as effective? How much is a healthy amount? Thanks

Amino stacks useless: Arginine and ornithine are nonessential amino acids. In fact your body makes ornithine from arginine. Lysine is an essential AA that MUST come from your diet. The typical healthy teen will see NO benefit from supplements. Arginine can boost growth hormone synthesis/release in the elderly but only at doses 10-20g per day and it only works because the elderly don't make much to start. Eat well not p ...Read more

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. ...Read more

Is it OK to take l lysine with Amoxicillin?

Is it OK to take l lysine with Amoxicillin?

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.

Sage Suggestion: It sounds like you already know the answer. If you do not have a deficiency of L Lysine there is no reason to take it. Lysine is an amino acid used to treat cold sores. There are other OTC and prescription meds that can treat Herpes Simplex viruses better. Lysine has not been approved by the FDA for HSV suppression. Go on line to read about natural sources of Lysine from food. ...Read more

What dosage of l lysine for cold sores prevention?

What dosage of l lysine for cold sores prevention?

1000-3000 mg/day: There have been only a few studies on this. They do show that l-lysine is highly effective for preventing cold sores. Some studies used doses of 1000 mg 3x/day while others used as little as 1000 mg/day. I usually advise 1500 mg/day. If you still get cold sores try raising the dose- lysine is quite safe. ...Read more

Is it safe to take l-lysine while nursing? I've had been fighting coldsores for 6wks and I have a 7w.o baby. Using abreva. Ice makes it worse.

Lysine and nursing: Lysine is an essential amino acid (protein) meaning our body cannot make it. It is part of our diet.We eat 60, 000 mg protein a day. For prophylaxis usually one takes 500-1000 mg a day and for an acute flare I have seen 1500 to 3000 mg/day given for 2-5 days. It may at very high doses interact with arginine another amino acid (but we have to have both in our diet, anyway). Discuss with doc ...Read more

Is l-lysine safe to take during pregnancy?

Is l-lysine safe to take during pregnancy?

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. ...Read more
