This is great for insomnia. I only have half a tablet before bedtime. The full amount makes me way too drowsy the next day. The whole tablet is too big to swallow anyway!

Gets rid of my cold sores fast!
Used this with l-arginine for athletic performance

I heard so many great things about this product but I did not like it. Lysine made me feel tired and stopped circulation in my hands. I also think it may have lessened the effect of arginine. Also lysine prevented me from reaching mood highs when exercising and it was as if i had a cloud trapped in my head

Since taking this I have slowly lost weight every week. I bought as a health supplement and although I am 20lbs over weight this was a bonus.I can really recommend this product and brand.

I started taking lysine for neurotransmitter-boosting purposes, but what I actually ended up noticing was a massive improvement in the strength of my nails. They've never been able to grow long because they have always broken easily but now they are like iron nails. I think my hair is stronger too.

I get fever blisters and read years ago that l-lysine can help heal them quicker. Well, i have been taking L-lysine daily for years and have significantly reduced not only the duration of fever blisters but the incidence. Since taking the Source Naturals brand I have had only one blister start to be stopped dead in it's tracks within 2 days. Excellent product at a great price.
Kept my mouth ulcers at away

I have suffered from painful ulcers in my gums epsecially during stressfull times at work. I was told that L-lysine was good for keeping cold sores at bay and thought i'd give it a go for ulcers. Now whenever i feel an ulcer starting to appear i smash a few of these and it receeds pretty quickly...fantastic stuff!!

If you're prone to getting cold sores as I have been, this is great stuff. If I notice a tingle I start taking it right away and keep taking it for at least a few days. It doesn't always prevent it totally, but the blister that forms doesn't break if I'm taking it. I also notice that avoiding dark chocolate (which I love) and almonds (which I love) is a good thing to do particularly around the time of menstruation. Chocolate and almonds have something int them that seems to feed cold sores. I also put a friend onto this when she had shingles (which is a type of herpes - as is chickenpox etc and she said it helped her too.
Not as effective and tablets are WAAAYYYY too big

Source Naturals is one of the supplement brands that I purchase often. Recently I bought the L-Lysine 1,000 mg 100 tablets because of the low price. The supplement doesn't seem to be as effective for my purposes as compared to other brands I've used. Plus the pills in tablet form are way too big. They are hard to swallow.
