5.0 out of 5 stars Sleep like a rock...and wake up like one, too., July 31, 2010
Amazon Verified Purchase(What's this?)
Ahh, ZMA. The famed all-natural sleep and recovery aid for bodybuilders and fitness enthusiasts. According to most supplement companies, it also increases free testosterone levels, though many studies show that this may not be true. Halfway through a bottle, here's what I've found:

Sleep - This stuff definitely knocks you out. If you take it as directed, 30-60 minutes before bed on an empty stomach, it hits you harder than "The Itis" after a Luther burger (Boondocks reference). You sleep excellently, too, and if you have to get up for any reason, you can easily fall back asleep afterwards. Some people say you have crazy dreams, but I don't ever remember mine, and that hasn't changed since I started taking ZMA. People also claim you wake up feeling awesome and ready to go, but so far I just wake up groggy as ever.

Recovery - This is sorta hard to judge, but my muscles do feel as though they are recovering faster after each workout since I started taking this stuff. Not quite as much soreness, either.

Testosterone - I actually think, despite some studies, that ZMA does have an effect on your testosterone production. I have read other reviews that say ZMA causes acne outbreaks, and I have observed this same thing over the past couple weeks. I don't think it's coincidence that soon after I started taking ZMA I'd randomly have recurring acne outbreaks that definitely weren't as bad before (I'm 19, by the way). But I'm no quitter, so I'm just going to finish this bottle and hope things go back to normal afterwards (there are other reasons I think this influences testosterone as well...see review title).

Other than the sleep, and some possible effects this supplement has had on my muscle tone/size (though there's no way to verify this), this stuff really isn't too fantastic. I gave it 5 stars though because it does what it claims to do. I won't be buying another bottle (unless I have a bad run of insomnia or something) any time soon, but if good sleep and recovery sounds good to you, I say go for it. Most people also have a daily magnesium deficiency, but if you take a good multi like I do you don't have to worry about this as much.

4.0 out of 5 stars You'll only count a few sheep with this stuff, December 15, 2010
Amazon Verified Purchase(What's this?)
Highly, highly effective as a sleep aid. I've been taking these for a few months, and it does provide deep sleep, but not to the point that you're too conked out to hear your alarm.

I don't have any more acne than before (the only other supplements I take are whey protein powder and a little creatine). I did have some unusual (although not disturbing) dreams for the first few days.

I don't have any noticeable difference in testosterone levels. I don't have more aggression in the gym than before, but I do recover well with this (I'm 33, 189lbs), and I've put on maybe 2-3 lbs of lean muscle since I began using the product.

4.0 out of 5 stars good suppliment- can lead to wierd dreams though!, August 25, 2010
Amazon Verified Purchase(What's this?)
I would recommend that you try out a small sample of this from a friend of from your local supplement store before you buy a large amount. It effects people differently and can cause very very strange dreams. Do not mix with alcohol either please! If you are going to take ZMA Optimum is the best brand! The amount of active ingredients per capsule is much higher than competing brands!
