Optimum Nutrition Zinc and Magnesium Aspartate Recovery Supplement, 180 Ct | Zinc Magnesium Aspartate Capsules, Zinc, Magnesium & Vitamin B6 Blend for Active Men & Women, Energy & Immune Support

Unfortunately, I am one of those people who has eternally struggled with sleep. Sometimes I lie in bed for hours in a vain search for sleep. If I finally find sleep, I then wake up at least 3 to 5 times throughout the night and I never really fall into a deep sleep. Never. I've went my whole life never really feeling that rested up. I've just gotten used too it. I've tried every pill, drink, tea, etc etc that I've found with varying degrees of success, but I hate taking pills night after night as I know sleeping pills can become addictive and can lead to even further sleep problems. I am an avid lifter and one day while searching for new vitamins/supplements to try I stumbled on someone who highly recommended lifters take ZMA. Intrigued, I researched it and found that ZMA had many great reviews and almost all of them stated how they slept much deeper for a better nights sleep while on this. While I've read many reviews on many other products that claimed the same thing, I decided to try this as well while very skeptical. However, after several months of taking this I can honestly say that for once a product lived up to the hype! While I wouldn't really say it helps me fall too sleep, it absolutely positively does help me STAY asleep!!! And when I wake up I feel like I slept a lot deeper than I've typically slept in the past. I definitely feel like this has helped my recovery time as well, although I don't know if the ZMA itself has done that or that it's just I'm finally sleeping better and deeper and giving my body more time to repair itself. I don't know why and I don't care, I just know that it works!!! Try a bottle, you won't regret it!

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!!

I was operating at a subpar level for so long, I forgot how great normal felt. I was always staying in shape, taking supplements, eating plenty, etc. Then I injured myself and couldn’t work out for a while and it all went downhill. Started getting more lethargic, less mentally astute, trouble sleeping, no appetite, and generally feeling like I’d been neutered. Then I tried this. First time I took it I slept 8 hours straight for the first time in a year. Woke up feeling rested and mentally clearer than I’d felt in a long time. I continued taking it daily before bed and kept improving. Was able to start training again after recovery. Didn’t purchase another bottle for some time after I ran out. Then when I did buy another one, my workouts felt as good as they did before my injury. It doesn’t make a Superman out of you, but it does get you to where you should be. Zinc and magnesium are extremely important when it comes to the symptoms I described above and this definitely corrected my deficiencies. I tried other forms from other companies but this one seems to work best for me so it’s the one I’ll stick with. Arrives quickly, and is as promised, and definitely priced right. As long as they don’t change the recipe or cut corners on quality, I’ll continue to keep buying. Five stars all the way!

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.

Optimum Nutrition's Muscle Recovery and Endurance Supplement with Zinc stands out as one of the best supplements available on the market today. As a staple in any serious fitness regimen, this product delivers consistent, scientifically-backed results.Timing and Absorption: I prefer taking this supplement at night before bed, which has significantly improved my sleep quality and overall recovery. While the supplement itself is not a sleep aid and won't make you drowsy, nighttime consumption optimizes absorption and allows the body to utilize these nutrients during the critical overnight recovery period when muscle repair and growth occur most actively.Scientific Benefits: The efficacy of zinc in muscle recovery is well-documented in scientific literature. Zinc plays a crucial role in protein synthesis, immune function, and hormone regulation—all essential factors for athletes and fitness enthusiasts. Additionally, zinc supports testosterone production and helps reduce exercise-induced inflammation, making it invaluable for anyone engaged in regular physical training.Quality and Commitment: Optimum Nutrition has built its reputation on using premium, high-quality ingredients without fillers or unnecessary additives. This commitment to quality ensures maximum bioavailability and effectiveness, which is why I consider this supplement non-negotiable in my fitness lifestyle.Final Recommendation: Whether you're a competitive athlete, weekend warrior, or simply committed to maintaining an active lifestyle, this ZMA supplement is a must-have addition to your daily routine. The combination of quality ingredients, proven benefits, and trusted brand reputation makes it an investment in your long-term health and fitness goals.

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.

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.

been buying this for years this time alot of the capsules were broke or half full . Its a good product dont know what happened

It knocked me out cold at night, this shows that the ingredients are authentic, also the zinc needs time to evaluate, since I got the ZMA for sleep and immunity and hair-loss.

very good product, one of the best ZMA in the market.

Ottimo prodotto, ottima marca

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.

Excelente.
