Great product and excellent value for money.
Quality sleep is extremely important to athletes. And there's also no question that ZMA is a breakthrough formula of phenomenal benefit. ZMA is an amazingly effective new sports performance product that's clinically proven to increase anabolic hormone levels and muscle strength in trained athletes. In fact, ZMA is the first nighttime anabolic formula developed specifically to enhance recovery by improving sleep efficiency. I have tried dozens of ZMA supplements, most of them have the quantities mixed, they have the wrong quantities of Magnesium and Zing, and some of them use cheaper versions of Magnesium other than Magnesium Aspartate. ZM6® Xtreme has the right amount of nutrients and it lasts longer than the usual ZMA supplements, usually they last one month and with ZM6® Xtreme you get two month supply at 3 caps per day or 3 month a 2 caps a day. You should take ZMA at night time 30 to 60 minutes before sleep and make sure you don’t take any food that contains calcium 60 minutes before you take it, as calcium doesn’t let the body absorb Magnesium. You should sleep much better with ZMA, as you go into deep sleep, the body releases more testosterone, you wake up fully rested and your energy levels will rise. This is an amazing product and great value for the money!!

Can't do without it - superb.
Superb product. I highly recommend it. I have tried a number of ZMA style products and this is by far the best. No grogginess in the morning, no or very little muscle soreness the next day after workouts, great deep sleep (and lots of it according to my FitBit data!), cheerful mood throughout the day, and bundles of energy right up until bedtime. I can't sing its praises highly enough. Everyone is different, but I started with 3 capsules nightly after dinner time to make sure I was asleep by 9.30pm - I train heavily so need lots of sleep! Some weird dreams indeed, at least one big weird dream per night, but that's expected with all ZMA-style products. My only advice is that if you do buy this product - AND YOU SHOULD - give it a full week (of nightly tablets) to kick in to your system, as during that week (while it's working its magic) you are probably still catching up on lost sleep from before. After that, feel free to adjust the amount of pills you take, and at what time of the evening you take them. I take them nightly - regardless of whether or not I'm training - to ensure a great night's sleep, EVERY time. If you Ttake 3 tablets per night you've got a 2 months' supply with this bottle - that's around 25p a day - GREAT value. Worth every penny. So do yourself a favour....you won't regret it!

If you haven't considered adding ZMAs to your supplement regimen I'd recommend you do so
The day-to-day energy boost hasn't been as dramatic as with some other brands but it has been more consistent. With a 2-3 month supply for the price you can't really go wrong. If you haven't considered adding ZMAs to your supplement regimen I'd recommend you do so. They're not as glamorous and immediate as some other supplements but they definitely improve sleep (thus increasing gains) and as a result you'll have better quality of energy throughout the day, leading to more consistent workouts. These are a solid option and come in an attractive quantity.

For me: A better quality, deeper sleep. Thank you Iron Labs!
The question that undoubtedly on your mind right now is "does this product work". Now I can't say if it will work for you, all I can tell you is how it has affected me, in a very honest and frank way. I have been a long time believer in the power of ZMA in aiding recovery/ general well being/ improving sleep. I used the Optimum Nutrition ZMA for 6 months last year and I had some great results - in regards to sleep. However, it became unattainable. My life circumstances over the past year mean that I dropped my Gym/Supplement regime down to minimum. Over the past few weeks I have picked it back up again, with regular gym sessions but also juggling this along side a very hectic work schedule. Thats where these tablets have revolutionised my days. Since starting these caps (I take 2 a night, however 3 works even better) my sleep quality has improved substantially. I wear a FitBit Charge HR at all hours especially during sleep (my sleep pattern hasn't been great, and once I get to sleep, I can't stay there) and the recordings of my sleep quality have changed beyond recognition. I am now falling asleep quicker and deeper and staying there for hours on end. I have gone from waking up and being restless for around an hour a night, to only 5 or so minutes. I wake up EVERY morning feeling unbelievably more alert., which is handed since my day starts with a two hour commute. I don't usually leave reviews, however this time I felt that I had to share my experiences. Sorry its a bit long. Pros: Deeper Sleep, better quality sleep, wake up feeling considerably more alert. Cons: Slight (and I mean slight) tummy ache in the morning. No problem with bowel movements or anything like that (however I have suffered with IBS in the past, this may just be a coincidence that I am experiencing this now)

Good Value Bulk Pack, but the Capsules are Massive
The Experience I started taking ZMA style supplements a few years ago to help with recovery after the gym and to try and improve my sleep quality. Usually, these can be quite pricey if you buy them from big-name fitness brands, so I went for this ZM6 bottle because the price for 180 capsules seemed like a steal. Taking them is straightforward, though I quickly learned not to take them on a completely empty stomach. Zinc can be a bit harsh, and the first time I tried these, I felt a little nauseous for twenty minutes. Now I take them with a small snack about an hour before bed. I’ve noticed that my sleep feels a bit deeper and I’m less likely to wake up feeling stiff after a leg day, which is exactly what I was hoping for. One thing that caught me off guard was the sheer size of the bottle. It’s huge. You definitely aren’t tucking this into a small medicine cabinet easily. Also, if you struggle with swallowing pills, be prepared. These aren't the tiny tablets you get in a multivitamin; they are fairly large capsules. Pros & Cons Pro: Great Value. Getting 180 capsules in one go is very convenient. It lasts for months, so you aren't constantly reordering or worrying about running out. Pro: Effective Recovery. I’ve definitely felt an improvement in muscle soreness the day after a workout compared to when I don't take a magnesium supplement. Pro: Vegetarian Friendly. It can be surprisingly hard to find these types of supplements without gelatin shells, so the vegetarian capsules are a big plus. Con: Capsule Size. They are quite big. If you aren't a fan of swallowing large pills, you might find these a bit of a struggle to get down. Con: Slight Aftertaste. If you don't swallow them immediately, there’s a bit of a metallic or chalky taste that lingers. Final Verdict This is a no-frills, high-volume supplement that does exactly what it says on the tin. It's perfect for anyone who trains regularly and wants a cost-effective way to manage recovery and sleep. Just make sure you have a glass of water ready and don't take them on a totally empty stomach if you have a sensitive system.

A good product at a good price
I do a lot of weightlifting, and have been using zinc and magnesium tablets to help maintain my testosterone and hormone levels for some time now. I find that zinc and magnesium also had the advantage of promoting deeper sleep, too - although dreams can be very vivid at times. I wake up feeling more rested and energetic. Previously I was using the sci mix brand; these are smaller and therefore easier to swallow, and have a slightly bigger dose. They have the following ingredients per serving (3 tablets): Magnesium 550mg Zinc 30mg Vitamin B6 25mg Niacin (B3) 5mg Riboflavin (B2) 5mg Biotin 50ug Vitamin B12 24ug Vitamin D 6ug These are best taken about 30 minutes before you go to bed, and preferably on an empty stomach. Drink water, as they do have a slight tendency to dehydrate. You may well find yourself needing to get up for a pee during the night. I originally bought this brand because a jar contains 2 months' supply compared to sci mix's 40 days - it works out much cheaper. They are also just as effective and I shall be continuing to use them.
