Great for Restful Sleep
Love this stuff, it makes me sleep like a rock. As I understand it, that's likely thanks to the magnesium. Everyone knows sleep is important for recovery and this stuff helps me sleep better than any other supplement I've ever tried.

I would advise any male age 25 and up to use this product
This product I use to maintain a healthy immune system during this plandemic. It is very good and it will help along with other protocols to maintain a healthy body, mind and soul. Compared to other zinc products ON's NMA IS THE BEST!!! Hands down!!!

Best sleep in a while
[This review was collected as part of a promotion.] My new favorite ZMA. I haven't had the weird dreams with this one but I think I haven't slept this good in months. Definitely would recommend this to anyone who will listen long enough.

Loved it!
[This review was collected as part of a promotion.] I recently started tackling a bigger/harder workout regimen and needed these! They came just in time. I did not experience an upset tummy, burps or any adverse effects. I actually felt like my body was fueled in a very healthy way.

Better Sleep
[This review was collected as part of a promotion.] I've been taking two capsules before bed the last two weeks. I feel like I'm sleeping better. I fall asleep faster and do not wake up repeatedly throughout the night. Plus, when I wake up I don't feel groggy. I have noticed that I am more focused and energized throughout the day. I'm sure its because I'm sleeping better, but also because I'm getting essential electrolytes. A few of my coworkers have noticed an increase in my energy level and have asked what I've been doing. I informed them that I am a BzzAgent and received a free sample of Optimum Nutritions ZMA vitamin and mineral supplement. Overall, I'm impressed with the free sample I received from BzzAgent. I will definitely keep using this product.

Good for athletes and ok for sleep
[This review was collected as part of a promotion.] What I found is that it replenishes must needed nutrients for me as I run a lot and work out. It does have a sedative effect when I sleep but as I continued its use, I noticed it had no effect on my sleep quality. I wouldn't recommend taking this every day but can take on days when needed for recovery

Overall good vitamin
[This review was collected as part of a promotion.] Though personally I couldn't take it long term due to it causing some heartburn issues I will say I wish I could take it. One pro to this that isn't listed is as someone who struggles with chronic constipation I was regular while taking this supplement. It was easy to swallow and didnt have a bad aftertaste or anything. Overall I would recommend this especially to those on everyday workout routines.

Quality brand and product
[This review was collected as part of a promotion.] This brand is definitely one I trust since I've been a fan of their whey proteins in the past. I walk, play disc golf and lift weights in the gym. Disc golf can be pretty tiring with all the throwing and walking involved, but since taking these supplements, I'm feeling less run down and more energized the day of and day after playing. Also feel like it helps endurance wise when lifting in the gym. Can't wait to see long term benefits!

Natural product for sleep
[This review was collected as part of a promotion.] I have had problems sleeping for as long as I can remember. I've tried over the counter, more natural leaning products like melatonin, and prescription pills that are strong and addictive. Some helped but the side effects were too intense. After I had gotten myself off of benzodiazepines I had a lot of problems sleeping. I ended up turning to natural problems which included Zinc & Magnesium so was excited when I got to try out Optimum Nutrition ZMA Capsules. What I like about these is that they are a combo of Zinc, Magnesium & Vitamin B6z so you get a full & well rounded approach to sleep issues. If you are having intense sleep issues this won't knock you out or anything but it does tend to have a slight calming effect & seems to work better with continued use every night. While it doesn't work like clockwork (for me anyways) it does give me an added boost to get me to that sleepy zone. And it does so without giving me a hang over effect the next day. I am into swimming & like to exercise every morning and don't get a hung over or excessively tired feeling after taking this. And I love that I didn't have any stomach discomfort from it. Usually magnesium is a diarrheal & can cause a lot of issues—-not with these! I'm very happy and will I continue them in conjunction with melatonin for a quality sleep.
