ZMA is an interesting one in that it is rather difficult for me to quantify my results, rather, I have to go on what I "feel" in one period relative to another. I don't feel that my strength gains when on ZMA can be traced specifically to the ZMA enough to comment, or growth, or success of cut/bulk cycle. So let me give you a subjective review of SciFit's ZMA (and opinion on ZMA in general) which I have run fully twice as of two weeks ago. (I am off right now)

It makes me have wacky-a** dreams. It makes me pee alot. It makes me realllly sleepy. Combine it with some Melatonin with theanine in it and you can just forget about getting up in time to go to work at a reasonable hour (im fortunate with my situation there). So it is hard for me to say, in some ways, whether I think it benefits me personally. I wake up more to pee, but I crash harder and longer. I know my sleep is deep because my dreams are consistently their every time I take it, so that is a clear designation of some effect taking place.

I think I would rate this product higher if I could sleep all the way through the night while taking it (I can when off of it for awhile, and/or just on Melatonin). I think that since this is helping me sleep deeper, when I do sleep, that it probably is helping me recover, release hormones, etc., thus the positive rating I gave it overall. Price is good compared to some outrageously priced comprable ZMA products from brands that I normally try first.

I think this is one you have to try for yourself to see your reaction to it. Maybe my reaction is just me, but I have heard it from others as well.

As it has been said in other reviews, it's a bit hard to review a product like this based on gains in the gym. I really can't tell whether the use of this has transferred to increased numbers. I consider ZMA to be more of a sleep/recovery product from my past experience with it.

Current Supps:
Con-Cret
Optimen
ON Whey
NOW Fish Oil
Scifit ZMA

Value: I bought this during a BOGO deal on bodybuilding.com; got two 60 serving bottles for just over $30. Not bad for a 4 month supply

Effectiveness: I've never really been able to tell much of a difference in test levels related to gym performance/gains. I buy ZMA mostly for the sleep/recovery aspect. This product in paticular has been a great help in that arena. The nightly deep sleep has been great. Dreams come easily and vividly for me on this product. That could be a good or bad thing for some people depending on dream cycles. I don't mind and actually enjoy that aspect of it. I haven't noticed any difficulty/groginess waking up in the morning outside of the usual "I need some coffee" foggy feeling I always have first thing even when not taking it.

Overall: A good recovery/sleep product (for me). I really have never expected more that that from ZMA and have been for the most part satisfied as the cost is low enough to keep as a on/off staple in my routine.

Okay first off I have to say ive only been using this product for about a week and already Im in love with it. Im a very light sleeper and have problems falling asleep, and staying asleep.
The first time that I took this product I remember having vivid dreams and next thing I was waking up for school. I felt great, I had tons of energy, and throught the day never once did I feel tired or droggy. Which is another problem I have and sure alot of people have is around 3 o clock you start getting sleepy again, I never had this

So overall great product for someone looking to add to a stack or just taking in general for overall well being

Allow me to begin this review by saying I like Sci-Fit's product line. I feel that they take a unique approach to supplementation and will not release a product until they're sure its effectively designed and well researched. If you visit their website it’s also hard not to love the hilarious interplay between their CEO Jim Vercellotti and Clark Bartram on Sci-Fit TV when they’re highlighting their products!
That being said I am not as impressed with this product as I expected to be after finishing the bottle. I was confident that with their pH buffer technology and extensive research that I would experience a quality product in their ZMA. What I found was a product that simply did not deliver consistently. Here's the breakdown of my experience:

Taste (N/A)- This product comes in the form of a 3 pill dose which can, depending on your pill swallowing ability, be tough to take all at once. I would advise to TAKE WITH PLENTY OF WATER. I made the mistake of not doing this and ended up having the capsules breakdown in my esophagus! I burped and I saw white smoke coming out of my nose and throat! It was one of the worst tastes I’ve ever experienced in my life not to mention it burned a little. Gotta love that sodium ash pH buffer. LOL a ZMA burp will be one of the worst experiences of your supplement career!

Effectiveness (8.1/10)- Here’s the rub with this product. I bought it solely to enhance the quality of my sleep but, while it performed sub-par in the sleep category, it excelled in others. As far as sleep went while I was supplementing with this product, there were some nights where I slept soundly. There were many others where I hit the snooze button multiple times before waking up because I was so groggy. Lol I came to call it a “ZMA-over”. Some nights I don’t think it helped me get to sleep at all. However, I did notice with fair consistency that I woke up feeling more rested as though I had achieved a deeper sleep. As a side effect I noticed that on some nights, when I first took the ZMA, that I’d get a strange Sensation in my lungs. Its difficult to describe but it was almost like having a light fluid in my lungs that I could feel with each breath. It wasn’t anything sinister but I thought I’d note it in my review.

Label claim: “ ZMA is a powerful all natural dietary supplement clinically proven to increase Free Test, total test, and IGF’s which may enhance muscle strength.”

I actually really feel as though this product helped me increase my testosterone. I know I’m 20 years old and it wasn’t a huge boost by any means but I definitely had more of the “alpha male” feeling when I was taking this product. There were definitely days where I felt like no one could f*** with me.
This product also aided me greatly in recovery and was a crucial part of my stack while running an intense 4 day training split in the football spring season.

Value (6.9/10)- Plain and simple? There are better products out there at a cheaper price. I’m currently at the end of my first week in taking NOW Sport’s version of the product and the difference is noticeable to say the least.

Overall (7.0/10)- This product fell short of my expectation. I WILL NOT buy this product again and its hard to say I’d recommend it to others but I might depending on their training needs, experience with supplements and dietary patterns. I’d also like to add that I didn’t quite give this product its due diligence. I often ate before going to sleep and it is well known that ZMA performs best on an empty stomach and that calcium can block absorption of Zinc. This may or may not have had something to do with the inconsistency of this product. However, I’d like to note that I do the same thing with NOW Sport’s version and it works flawlessly every time.

Cut the dose to 2 per night. Decent stuff. Feel more aggressive in my workouts. Anything more then 2 is a recipe for nightmares. If your dreams are 2 intense cut the dose down. Deffiantly feel more agressive in the gym what more can I say?

As I've had lots of good results from different Sci Fit products, I was tempted to try Sci Fit's ZMA as they had a bogo free deal a few months back.

Value: 9/10 I rated a 9 out of 10 without the bogo deal. It is only around $12 for a one month's supply which is a steal in the supplement world for any product that can product results. If you're looking for a cheap ZMA, BodyBuilding.com has on a few occasions had this bogo free.

Uses and Effectiveness 8/10

One of this first reasons this will grab somebody's attention is that there is actual proven research behind ZMA. Research has shown that ZMA has naturally raised testosterone levels in athletes at various levels. For this reason, you will see ZMA not only sold by itself, but also in many natural test booster supplements. Sci Fit's brand per serving contains 30mg Zinc (200% dv), 450mg Magnesium (113%), and 10.5mg Vitamin B6 (525% dv). From my experience, I can't say that I noticed anything in the line of test levels being raised. No noticeable moodiness, libido increase, or stength gains that would make me think as such.

Where I did notice the effectiveness was as a sleep aid. Up until ZMA, the best sleep aid I tried was Melatonin. Anyone who has tried both will definately tell you there is a difference in the sleep produced. While both make you sleep pretty deep, ZMA makes me need much less sleep than I normally would need. Sounds like a sales pitch, but honestly, 7 hours of sleep with ZMA feels like 9-10 hours without. You really notice the good effect when you wake up completely energized with no sleepiness. I found this helpful when I stay up later than I would like to and have to get up earlier than I would like, this makes up for the few hours of sleep I might be lacking.
From a lifting standpoint, where this really helped me was in my recoveries. Sleep is really the best recovery for lifting and I felt less sore and more energized coming into my workouts when I was on this.

This also has the effect of eliminating that 2:30 sleepy feeling that many of us sometimes get in the middle of the afternoon. Didn't get that even once when on this product.

The only negative I found is that I was running to the bathroom more often when I took this, almost like there was something there my body didn't completely want.

Overall, if you haven't tried ZMA, it is a great sleep aid, helps with recoveries, and will keep you more energized throughout the day.

ZMA is a blend of zinc, magnesium, and vitamin b6. ZMA is a awesome supplement, but is often misunderstood.

Intro-

As a high school student with a part-time job, and a 5-day split workout schedule winding down at the end of the day can be tough. Some people just jump in their bed at the end of the day and can fall automatically asleep. On the other hand, it takes me a little while to get my Z's in.

Effectiveness-

I usually workout at around 5 to 6 PM so I take my PWO supplement pretty late in the day so sometimes I am full of energy at bedtime. ZMA defintely does help me to fall asleep. It's not gonna knock you out like a RX-strength sleep aid, but when I lay down in bed I feel a lot more relaxed. For me it's similar to Melatonin in effectiveness, maybe even a hair better.

I'm not sure if this is related to ZMA, but as of lately I have had some vivd, recurring dreams. I cannot attest this directly to ZMA but it is something to note.

Value-

The value of ZMA is a major selling point. ZMA is a product that if I was tight on money I would not purchase. IMO it is not a staple, but it is a awesome product. On BB.Com ZMA is
$20 for 180 caps. 3 caps=1 serving, so each serving is about 33 cents. Not too shabby at all.

I have even seen ZMA for lower prices by different brands but I trust SciFit so I will always go with them or Optiumum for my ZMA.

Things to note-

I constantly see people advising ZMA as a stand-alone natural test booster or in a stack. The only way that ZMA will effect test levels significantly is if your body is mildly deficient in Zinc. So if your taking a Multi, don't purchase ZMA banking on it's so-called Test boosting properties.
Even if you are deficient in Zinc it would be much cheaper to just purchase a Zinc supplement.

Calcium directly interfers with the absorption of ZMA so take your ZMA and then you can have your caesin shake an hour later or before.

People often report feeling energetic upon waking up, for me not at all! I maybe even feel a little more cranky when I wake up but it's only for those first few minutes or so.

I personally did not see an noticeable increase in recovery time when taking this product.

Conclusion- ZMA is a very simple supplement, it is a cheap, effective, and valuable product for sleep aid.

That's really it for ZMA, doesn't do much more, doesn't do much less. If you are tossing and turning in bed this is an extremely effective product that helps.

Good ZMA product just as good as the other ZMA products, but for a low price. very good to take after a long workout day. Do not take milk with this product and take 30-60 minutes before bedtime. If you get it off BodyBuilding.com type in 25perSciFit in the promo code section and you get 25% off the already low priced product.

This was very good as it aided restful deeper sleep and after 30 days could see some strength gains in the gym.
