(More customer reviews)I had no idea what L-Arginine was until a couple of months ago. I found that it was one of the main ingredients in a pre-workout energy drink mix that I was using, and so I did some research and shopping around to find a cheaper source, since the drink mix was nearly $3 per serving (one serving contained 2500mg L-Arginine).
I ended up buying this bottle, along with a bottle of Source Natural 1000mg tablets to try out.
Well, this one wins. And here's why.
First of all, this pill is 1250mg L-Arginine and 750mg L-Ornithine. Supposedly, they're good to take together. Any evidence to this effect seems to be speculative or anecdotal, at least from the short time I spent looking it up. Point is, I guess it can't hurt to have both. The pills are nearly the same size, so you may as well take this one, since the other one is only 1000mg L-Arginine with nothing else.
Second, they're slightly cheaper per gram. The 300-count bottle sold here, if you do the math, is approximately 9.8 cents per 1000mg L-Arginine. The source Natural tablets (sold in a 2-pack of 100 tablet bottles for 200 tablets total) comes out to 11.5 cents per 1000mg L-Arginine.
Third, the Source Natural pills are big, white chalky tablets that taste awful. I don't have a problem swallowing large tablets, but that doesn't mean I enjoy it. :) On the other hand, these are gelatin capsules, and they go down really easily.
Apparently there are a number of good reasons to take these. Personally, I take them as a workout supplement, about 30-45 minutes before starting. I'm currently taking 3500mg (two of these and one Source Natural tablet to get rid of them) before each workout. The difference is noticeable. The actual time I can keep up a given exercise before resting is significantly longer. Once I'm ready to rest, it's only a couple of minutes before I'm ready to go again. When in a group, I'm always the last one that's ready to leave the gym. As a result, the pace with which I am getting back into shape has increased since taking the supplement.
Highly recommended. Seriously.
