Another excellent product from ON Nutrition- and they do help me sleep better.

I get very good sleep from this zma. I gave it a while to see if my body would get used to it before it stopped working and it is still pretty effective.

I take 3 capsules before bed every night. I find that since taking the product I sleep far deeper then I have in the past. I was in the military for ten years and suffer from insomnia. I find that when I take this product I wake up far fewer times and I wake up rested in the morning ready to go. I haven't taken the product long enough to see the testosterone benefits associated with ZMA. Currently I'm cutting so mass gains are not the goal. I do however find that my overall workouts have improved and I'm currently getting in the best shape of my life. I can't single this product to this but along with the other supplements I'm taking and the hard work I put it- it's all working and so I don't plan on changing anything with the current supplement regime I have.

Excellent product, helps you have a deep restful sleep and waking up refreshed, noticed the effect after 3-4 days. منتج ممتاز يساعدك على (المحافظة) على النوم العميق وتقوم بالصباح بكل نشاط، بدأ مفعوله بعد ٣-٤ أيام.

ZMA definitely helps me sleep better! Takes about a half-hour to kick in and I'm ready to go to bed! Since I started using it, it's also reduced my migraines...probably because of the magnesium. I take magnesium separately as it helped take my migraines away (over time). I haven't had one in about 5 months. I'd assume the magnesium in the ZMA just gives me a little more aid to the reduction of those migraines!

Definitely allows me to sleep better at night. The first few times I used it, I felt a little lag the next day but after a few days that went away.

I did intense workout for the last 2 years. I bought my first ZMA 1 week ago and I must say this thing changed my life. I have huge sleep issue for many years. I am waking up 7 to 8 times a night. Wake up in the morning and would sleep hours and hours again. Trying different thing like melantonin, worked for 1 day. Woke up with death in my eyes. With ZMA, I am not falling asleep before before but I am getting better nights. I am waking up only 1 time to pee, that's all. Wake up and immediately awake like if it's was 4pm. Too soon to see any difference at the gym but I already see results regarding sleep quality.

I like this ZMA because it doesn't contain melatonin. If you take melatonin on a regular basis, even a little bit, I read that your body will stop producing it naturally. A lot of ZMA's include this. And ON is priced just right.

I had some crazy sweet dreams with this. I feel energized the next morning even going to bed late. I feel stronger. The pills are easy to take too.

This product is great, in my case it does not make me fall asleep faster, but does increase the quality of my sleep. I usually wake in the middle of the night(for various reasons) and feel ready to get out of bed and start my day. That being said, I can go right back to sleep and wake rested in the morning! it's best to follow the label directions and take on an empty stomach, and without calcium present. So, i like to partially separate the capsules, but not fully, then swallow them down with a couple gulps of water. I do this at least an hour before my bedtime shake/glass of milk. Great Product!!

My coach suggested I start taking ZMA because of severe muscle cramps. This is the only thing that I ever found that helped!! Cramps are few and far between and never as severe!! Wish I would have found this product a long time ago!!

This is my favorite product for helping myself get to sleep. I fall asleep better and sleep more deeply on this product. This product did give me extremely vivid dreams. This is my favorite sleep aid.
