Product Overview

ZMA is an advanced formulation designed to support strength, endurance, recovery, and growth.* Through an extensive search of worldwide research data, we discovered that rigorous exercise results in the losses of zinc and magnesium.* ZMA was designed based upon the biochemical testing and performance monitoring of many world class Olympic and professional athletes.


Does exercise effect sleep?

Studies involving the effects of different types and duration of exercise on sleep efficiency have yielded conflicting results. However, in a study of the effects of power exercise on the sleep of a group of trained power lifters, the tendency was for this type of more strenuous exercise to affect sleep adversely (3).* Excessive training has also been reported to cause sleep disturbances as well as mood changes, and the sleep disruption was greater at higher training volumes (4).*

Does age effect sleep?

Sleep quality declines with age, with progressively less time in deep or slow wave sleep (SWS), which occurs during the initial part of sleep. Normal age related declines also occur in lean body mass, healthy growth hormone (GH) and insulin-like growth factor 1 (IGF-1)(6).*
Does exercise effect testosterone levels?

First of all, it's a widely held misconception that exercise increases testosterone levels. In fact, prolonged exercise decreases the production of testosterone by approximately 10% (11).* Many studies have reported post-exercise increases in serum testosterone levels, however, what they're measuring is only a temporary false elevation. This is because exercise causes significant decreases in plasma volume, hepatic plasma flow and the metabolic clearance rate of testosterone. This is the reason it's extremely important to measure testosterone levels in a rested state during the early morning as opposed to post exercise. A large percentage of the testosterone secreted daily occurs during sleep and levels peak during the early morning and decrease throughout the day by 25% to an evening minimum (12).* Does age effect testosterone levels?

Testosterone levels significantly decline with age. Serum testosterone concentrations were examined from over 4,000 military veterans and their testosterone levels dropped by more than 30% from age 32 to age 44 (13). In another study of over 1,400 men aged 20-60 years old, testosterone levels showed a significant stepwise decrease with age starting with the early adult years (14).*

How does ZMA effect testosterone levels?

An independent study of ZMA was recently conducted at Western Washington University under the direction of sports performance researcher, Lorrie Brilla, Ph.D. A group of 12 competitive NCAA football players who took ZMA nightly during an 8 week spring training program had supported normal free and total testosterone levels (1).*

How does ZMA effect muscle strength?

In addition to measuring the healthy testosterone levels in the football players, Dr. Brilla measured their muscle strength and functional power increases. Pre and post leg strength and power measurements were made using a Biodex isokinetic dynamometer. The players who took ZMA nightly during the 8 week period of intensive training had greater strength gains than the placebo group.* The ZMA group also had two times greater functional power gains compared to the placebo group (1,2).*

Don't athletes get enough zinc and magnesium from foods?

It is difficult to get proper amounts solely through the intake of whole foods.b> USDA studies show that 68% of self-selected diets contain less than two thirds of the RDA for zinc (27) and 39% contain less than two-thirds of the RDA for magnesium (28).* While zinc and magnesium are contained in a wide variety of foods, it's been our experience that athletes don't acquire sufficient quantities through their normal diets. One reason may be that foods high in these minerals aren't necessarily the most desirable.* For example, the best food sources for zinc include oysters and beef liver. These foods just aren't consumed by most athletes, nor should they be.

I have used it off and on for many years. I first used it 1994 when I saw it was endorsed by Mike Ashley who I have never seen endorse any other supplement. It worked then and it still works today. Not a magic pill but it does improve recovery, strength and sleep. one of my long time staples.

I'm really on the fence as to whether or not i've noticed any actual gains in strength due in part from taking SNAC ZMA. I definitely notice a nice deep sleep, but sometimes it's actually too deep. I won't even hear my alarm, or when i do i may be a bit groggy. One thing that really annoys me as after having gone through about 5-6 containers of this supplement, i've NEVER once received all 90 capsules as stated on the label.

I have been taking ZMA for few months but I can't really say that I feel any difference. This is why my review is neither good nor bad but more so neutral. My sleep quality has not improved and from what I read this is the best way to supplement with zinc and magnesium, not so much for better sleep, even though this is one of the supposed benefits. I don't know if it is working or not. I don't feel the great benefits which the experts say it should deliver but even if I don't sleep any better at least I am getting some extra minerals.

I started taking SNAC ZMA about a month ago, right from the start I noticed the quality of my sleep was greatly improved. I sleep soundly through the night and no longer wake up periodically during the night. I also wake up feeling energized and ready to conquer the day! I greatly enjoy the benefits of this product and will be buying again!

I started taking ZMA about 3 weeks ago, I noticed having deeper sleep and more vivid dreams. I wake up feeling rested even if I don't sleep 8 hrs.

Definitely felt a difference when using the product. My sleep was noticeably deeper.

I began taking SNAC ZMA several months ago and noticed it significantly helped my quality of sleep, which gave me better muscle recovery as a result. At one point I ran out and decided to try going without it. My sleep quality digressed and I was exhausted and very sore each morning. At this point I've decided that SNAC ZMA is a critical supplement for me to take, and I plan to take it for a very long time.

The icing on the cake! End the day with some ZMA. This product is great for sleep aid and recovery but you absolutely MUST follow the directions or it will NOT work properly. Take before bed and avoid calcium at all costs as calcium negates the effects of any ZMA product.

If you have trouble getting a good night sleep after training, ZMA is definitely the way to go.

One of my favorite brands of ZMA. They're actually the creators of it so why would you want to buy any other version?? Gives me a super restful sleep every single night I take it and would recommend to anyone who's looking to recover and get a good nights rest!!

I like this brand of zma because when I take it I don't get any funny pill taste in my mouth. It helps a lot when I take it before bed. I usually wake up feeling really good.
