L-lysine

I love www.iherb.com . There's a new customer coupon for $5 off if I'm not mistaken (google "promotion code Iherb).

It's great because you can read customer reviews. They also have good quality supplements in my experience.

I'm not a fan of box store or drug store supplements, mainly because they contain more "fillers."

That's not to say everything at iherb is great.

Good luck.

Yeah, walmart has it really cheap. That's where I last got ours.

I love puritans pride for all my supplements. They are a respected company so you know the products are safe. They also run BOGO deals all the time. They have one going on right now until the beginning of June.

Have you tried just going to Wal Mart? I haven't bought it in a while but I don't think it's that expensive...you can just get a generic large bottle. I suppose you could even try Wal Mart's website but I dont know if they sell that kind of stuff on there or not.
