Great Supplement overall for athelets and others
Its good for those who exercise excessively among other benefits. I take this on heavy weight training days or especially after a long run day. Mag, Zinc and B6 are essentials and you can get them other places (foods) but this is a great supplement before bed. These doses although over 100% won't exceed what some consider excessive daily limits. Zinc is about the only one that reaches a lot of common limits. Again, if you eat a super healthy diet (who does) you could always just take two pills as a dose and still get the benefits. Again, I take on heavy training days or that evening before bed to be specific. If you are taking other supplements just read the labels to see which ones you are double dosing on. A few notes on these: Vitamin B6, also called pyridoxine, is a water-soluble nutrient that is part of the B vitamin family. B vitamins help support adrenal function, help calm and maintain a healthy nervous system, and are necessary for key metabolic processes. Vitamin B6 acts as a coenzyme in the breakdown and utilization of carbohydrates, fats and proteins. Vitamin B6 helps in the production of neurotransmitters, the chemicals that allow brain and nerve cells to communicate with one another, ensuring that metabolic processes such as fat and protein metabolism run smoothly, and is important for immune system function in older individuals. Magnesium is the fourth most abundant mineral in the body. A balanced diet usually supplies all the magnesium a person needs. Magnesium also helps maintain normal blood pressure and metabolism. Beyond that, a magnesium-rich diet may help protect against metabolic syndrome, a combination of risk factors that can lead to obesity, type 2 diabetes, and heart disease. ****Because all forms of magnesium can act as laxatives, I suggest taking it with some calcium to balance its effects. The forms I prefer are magnesium citrate, chelate, or glycinate. Avoid magnesium oxide, which can be irritating to the digestive tract. Zinc is a mineral that is necessary for the functioning of enzymes and plays a vital role in many biological processes, including the production of cells that help keep the body healthy.

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*”

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.

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.

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!!

These are essential and worth the money!
After looking at the reviews I personally have never noticed any change in my dreams that others are speaking about. But I have been taking these for just about a year now. When I really starting getting into lifting I took an interest in monitoring and managing my testosterone levels. I realized that the stress from both life and working out was taking a big toll on my optimal testosterone levels. I knew without a doubt I was not going to start or get hooked on any test boosters so I did A LOT of research on how to manage them naturally. ZMA seemed to be a HUGE factor that came off very frequently and is such an easy change. So I pulled the trigger and bought them. I definitely started to notice a difference in size, stress, and recovery time. Along with increasing my levels of natural fats, ZMA has played a big role in my muscle recovery. Since sleep is such a huge factor in recovery I wanted to do every little thing i could to improve the quality of it. I noticed a slightly more fulfilling or deep sleep and the quality went up. If you are training intense, ZMA is a simple must. Click YES if this review was helpful. If you have a question, leave a comment and I'll answer you! Feedback helps me improve my review! Thank you!!!

Faster recovery, strength gains, and sleeping like a baby!!!
Optimum Nutrition equals great products at great prices that work as advertised!!! I started taking these for multiple reasons: to get better/longer sleep at night and to naturally boost my testosterone. Well, I think I picked a winner. I did not feel as if these were working until I had been taking them a few days. Then I noticed I was getting good quality, deep sleep for longer periods of time. Being a very light sleeper, these have enabled me to get much better sleep. When I read other reviewers accounts on their dreams I thought it was nonsense, well, I have to say that I have had some very vivid dreams since taking them. I can't say whether it is the ZMA or the fact that I am getting very deep sleep for longer periods of time that I am used to. As far as boosting my testosterone, I feel my recovery is faster and my workouts are going much better. These supplements combined with healthy eating and weight training/cardio are a good addition to my arsenal. Pros- great price, great quality, no aftertaste, easy to swallow, enable you to sleep like a baby!! Cons- If you have a thing against having dreams you may not like these
