  • Product Overview

    ZMA: Powerful Patented Formula

    ZMA® is a unique combination of zinc and magnesium plus vitamin B6 and has a number of benefits to the body and its functionality. Each of the three ingredients have been specifically chosen for their unique properties.

    Highly popular with bodybuilders, seasoned gym goers, and fitness fans alike – it’s a great addition to your daily diet.

    What are the benefits of ZMA?

    Magnesium contributes to electrolyte balance and the maintenance of normal bones and teeth, the normal functioning of the nervous system and muscle function, normal protein synthesis, normal psychological function, and a reduction in tiredness and fatigue.

    The added zinc contributes to the normal function of the immune system, macronutrient metabolism, normal vision and the maintenance of normal skin, hair, and nails. It also contributes to normal cognitive function and helps protect cells from oxidative stress, as well as the maintenance of normal testosterone levels in the blood.

    Vitamin B6 adds to the mix by contributing to normal protein and glycogen metabolism, normal function of the immune system, and to a normal energy-yielding metabolism.

    The combination of zinc, magnesium and vitamin B6 means ZMA® is a worthwhile addition to any supplement regime, whatever your fitness ambitions.

    When should you take ZMA?

    To get the maximum benefits, we recommend taking two capsules daily, preferably on an empty stomach, 30-60 minutes before bedtime.

    Upgrade your gains: how to maximise results

    ZMA is a great way to make sure you’re getting all the benefits of zinc, magnesium, and vitamin B6. But, to make sure you’re getting all the vitamins and minerals your body needs, add Alpha Men – packed with a whole host of essential vitamins and minerals, this is the perfect daily supplement for the active man, whatever your fitness goals.

Better sleep, for a night owl

since having two of these a night, I fall asleep quickly! this is great I recommend to anyone who can't switch off at night.
Goes Well With:


Ive always been a pretty bad sleeper and a pal mentioned ZMA take 3 of them before sleep every night and ive been getting tge best sleep ever. I have the odd nightmare but its worth it. Wouod highly recommend


Great quality product. Helps me sleep better at night.
Goes Well With:
Any other supplement


I just reordered some ZMA after running out, the new tub I got has have a smaller serving size, and a lesser quality serving. Time to start looking elsewhere I guess.

Does the job

It works well but after a week or so 2 tabs is no where near enough for any sort of effect, that is not a knock on the product though I suppose.


Superb item, never ever slept better I fall asleep easily and wake up rested. Stool is softer and easier to pass also.
Goes Well With:


This is my first ever protein shake and it is so yummy! I look forward to my shake everyday. The only downfall is that it doesn't dissolve easily and there's always clumps of powder, however it's still really tasty and I would buy again. The item arrived promptly and was packaged well.
Goes Well With:
I make mine with Almond Milk

Works exactly as stated.

I’ve been a long term user of Amatryptaline which I was originally prescribed for pain but have now become dependent on to sleep (it’s a pain killer primarily but also a sedative.) Without taking 10mg of this at night it would take me 4-5 hours to go to sleep. I really wanted to get off it though and happened to get a bottle of ZMA as part of a weight loss kit with my protein. I use an app on my Apple Watch called AutoSleep. I wear the watch to bed and it tracks my heart rate and movement to establish several sleep parameters. These are, time asleep, quality of sleep, amount of deep sleep, and time it took to go to sleep. The following are average figures from my logs when I was taking amatriptaline: Results over 7 days: Sleep quality: 3-4.5 hours Deep sleep: 1.5-2.5 hours. Average heart rate: 10bpm lower than normal HR. Results over 7 days taking ZMA Sleep quality: 5-6.5 hours. Deep sleep: 2.5 to 3.5 hours. Average heart rate: 15bpm lower than normal HR. The results speak for themselves. This product works. It’s sstablished that ZMA can lead to nightmares with some people, and that seems to be reflected on the poor reviews, but I can say this was never the case for me.

Horrendous nights sleep

I bought these to try, recommended by a friend to aid recovery. After only taking two tablets instead of the three stated, I suffered the most vivid nightmares I've ever experienced in my life. Won't be using again.

Does the trick

It would normally take me a good half hour to fall asleep but since I’ve been taking these I’ve fallen asleep a lot faster. The instructions say to take 3 a night but I started with 2 a night and they do the trick just fine
