Optimum Nutrition ZMA, 180 Capsules

Be careful with this supplement. Zinc is proven to improve sleep and sex drive but you do not need huge amounts as it has severe side effects long term and short term. That said 3 capsules is WAY TOO MUCH. 40 mg is the upper limit you should take for zinc and one serving size has 30. There is no chance you are not taking at least the 11 mg of zinc that are RI anyway as studies show that there are only few people with zinc deficiency. One to two capsules is more than enough. They have a bigger serving size so you will finish the bottle sooner and buy a new one. Also there is no reason to really buy this. You can buy the optimen multivitamin from the same brand which includes enough zinc magnesium and b6. The reviews here that say their sleep was improved tremendously are probably experiencing placebo effects. Most importantly this is not fda approved while the optimen multivitamin is. If you want to just throw away your money that's your choice. But just be careful while doing it.

Easy way to see if this works is get an app called Sleep Cycle. It checks sounds to give you an estimate on how well you're sleeping and helps you figure out how much deep sleep you're getting. It gives you a sleep quality percentage rating at the end. Before I used ZMA, I was barely getting any deep sleep. With this, I'm having no trouble at all and feel much better in the morning.

Reason for taking ZMA: to replenish magnesium and zinc levels after my high-intensity training sessions.Did it help me get to sleep faster: NoDid it improve my sleep quality: YesWere my dreams more vivid: YesDid it give me nightmares: NoDid I feel refreshed in the morning: Yes, but I didn't oversleepConfounding factors:I took ZMA right before bedtime, and after doing post-exercise yoga i.e., I was not tense when I went to bed.Had I not done yoga, I may have had nightmares, which for me, often occur during the nights when I go to bed with muscular tension.I do not take this supplement every night, so I've no idea whether the pharmacological effects of ZMA diminish with constant use. I am using ZMA only after high-intensity training sessions!

I really like the product but the price hike is a joke.

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.

To begin with ON is a high quality brand, and their products are brilliant. I’ve bought this ZMA many a times (from Amazon 14 times)! Every time I use this ZMA I get a very good night sleep, with plenty of dreams! Helps a lot with recovery from gym workouts! Highly recommend it! Great value for money!

This was my first order with this seller and I've been impressed with their delivery time. I ordered them on the Thursday night and they were with me on the Monday morning (a bank holiday!). The tablets are good. I've been taking them for several years now. 2 a night is the best dose for me, 3 can often give me a headache after too deep a sleep. Taken in combination with glutamine is good.

As a user of ZMA for a while I can confirm that the formula works. I take these as part of a low inflammatory diet (low in sugar and higher in fats) to maintain optimal recovery and immune function. I'll be ordering these again.
