Great for right before bed
The magnesium helps to support sleep and a lot of other essential functions in our bodies. Zinc is important for keeping us from getting sick. B6 also supports a lot of functions and is important to not become deficient. An added benefit of this combo that isn’t talked about much is that it seriously increases your semen output for men. Like Frank Thomas says: “she’ll like it too *wink*”

Important for Quality of sleep!
I love these pills! I have been taking these for at least 3-6 months now. And I find that I have a BETTER quality sleep with these. I wouldn't say that they make me feel sleepy whatsoever... I have to do things earlier in the day and change my diet to want to fall asleep sooner. But I find that I feel more refreshed with these. I don't feel like I am missing out on something. When I don't take these, I feel like I had the worst night's sleep even if I did get 8 hours. I am an athlete that plays sports about 2-3x a week (pickleball, volleyball and softball). And then I also work out 5x a week. I will tell you that the SIZE of these pills are a bit bigger... so prepare to swallow. These are capsules. So I would NOT recommend cutting into these pills as the ZMA formula will spill out and you will not get the right dosage.

Recovery and Nothing More
Optimum Nutrition is the best supplement provider on the market. In the health industry companies and brands come and go like the seasons, but ON always remains. They make great, affordable, supplements that work and don't add any junk or fillers. This company is best known for their whey isolate and it really is the gold standard for weight lifters and competitors. They also make a very good ZMA, Amino Energy and Creatine supplements. I know that when I buy ON products I'm getting a quality product that won't taste like garbage. If you've tried more than one protein powder, then you know what I'm talking about! I'm going to give it to you straight, this stuff will not increase your sex drive or help you sleep more soundly. I've been using ZMA since 2008 on a 3-1 cycle and I have never noticed a difference between on and off months. What it does do is help you recover while you're sleeping. When I take ZMA I feel less drained and less sore than when I don't take it. There is more than one study out there that links ZMA, Tribulus, and other test boosters to placebos. It may be possible that it helps you maintain a normal hormone level, but it won't increase hormone level production.

Impressed
I hardly ever write a review. I purchase things from Amazon literally a couple of times a week and it’s been months since I’ve taken the time to review it on here. I am a 30 year old female and I don’t think I’ve ever actually had a really good nights sleep in my entire life! Or at least one that I can remember. Not only am I an extremely light sleeper, but I fractured my neck about 3 years ago & im not a fan of taking pain medication so I just kind of deal with the pain and discomfort I often have. It has made getting to sleep at night more of a challenge for me sometimes, but I still never miss my 4:30am workout sessions! But because of this, I am seriously ALWAYS tired. I’ve actually wondered to myself how other people feel and if they’re always as tired as I am, and if my tiredness is just normal and it’s how all humans function?! I’ve heard about ZMA in the past but I was skeptical about trying it. I’ve used NyQuil Zzz sleep aids, melatonin, and a couple of other non medicinal sleep aids. They’ve never worked well enough for me to be impressed and I’ve still always been tired. Last night was the first time I’ve ever taken ZMA. I took it about an hour before I went to bed. I started getting a little discouraged because I didn’t think it was making me sleepy like it should. I took it at about 7pm and by 8pm I figured I would go lay in bed anyway to see if laying down would make me realize I was tired. It wasn’t even 10 minutes after laying in bed that I fell asleep! And I didn’t just pass out like I do when I take NyQuil and can’t keep my eyes open anymore. I felt like it was a “normal” way of falling asleep. I didn’t feel super groggy, but I just closed my eyes and fell asleep. I had VERY vivid dreams like others had mentioned. I don’t mind that because I think dreaming is fun. I only woke up ONCE last night to use the bathroom which is seriously a miracle because I usually wake up every single hour of the night. And when my alarm went off at 4am to wake up and get ready for my workout, I didn’t feel like I should keep hitting the snooze button on my alarm because I just felt wide awake!!! I’m not groggy or anything at all and for the first time ever I genuinely feel well rested! I am seriously impressed with ZMA and I will continue to use it! I will tell my friends and family about it and I’ll most likely never use any other sleep aide again. I highly recommend trying this if you feel like you need to get a better nights sleep. Especially if you wake up early like I do to workout. A good nights sleep is the only way to get a good workout in!!

A great product that supports a demanding training regime. I know this works as I have come off it several times in the last two years and have noticed a drop in performance due to poorer recovery rates, this meant easing up on my training regime which I wasn't happy doing. Another benefit of this product is the noticeable assistance in quality sleep. My current work and training commitment means I only get 5-6 hours sleep a night and two 35 minute training session either end of a full days work, this product helps support this lifestyle which isn't bad considering I'm almost 50. Buy it, try it, you will surprised how effective it is.
