Horse pill sized

Posted by Reviewer1183143 on Jul 09, 2012

I am only making the point here that the website info on expiry date etc is really helpful. But rather than the package size, it would be better to know the size of the pill. These are hard tablets and they are HUGE - I cannot get them down without choking. If I cut them, the edges are too sharp and hurt my throat. I recommend for ALL listed merchandise, PLEASE show the dimensions of the pill/tablet.

Sleep Tight

Posted by 5485951632908139042 on Dec 27, 2013

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!

Used this with l-arginine for athletic performance

Posted by 5536595171908109527 on Feb 09, 2014

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.

Pleasantly surprised.

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.

This helps

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

Posted by Reviewer1741178 on Oct 30, 2012

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.

I am satisfied with this product, however be cautious, pills are really really huge and I am used to swallowing big pills but those are the biggest I have ever seen, I manage to swallow them but still. I am taking lysine for healthy tissue maintaning and stronger bones and teeth also to help fight with cold sore. I am not sure, but while taking lysine my lips got chopped, dry and itchy. Maybe because of imbalance of other amino acids, but still, I find it odd.

Thanks iHerb for this strength in L-Lysine!

Posted by Reviewer1625204 on Mar 27, 2010

My husband takes a very high amount of L-Lysine (controls cold sores on his lips) and (for years) has taken "alot of individual tablets" to meet the amount his body needs. This product is a wonderful way for him to more conveniently get the MG he needs! Source Naturals is a super brand and great value!!!
