ZMA Description Supplement Facts and Usage Reviews

We hear a lot of athletes who ask, “Aren’t all ZMA formulas the same?” The answer is a resounding no. ProSource’s ZMA is an ultra-premium-grade complex that provides real results for those looking to increase testosterone, strength and vitality. This complex of zinc, magnesium and vitamin B-6 has been shown in university research to provide significant gains in college athletes. (See chart at right.)

In an 8-week double blind, randomized clinical study, tests were conducted to determine the effects of ZMA on strength levels of college athletes. Among the results was a remarkable 11.6% increase in strength compared to the placebo group (4.6% increase). The overall study findings showed that ZMA significantly increased strength and power in athletes.
The World's Best ZMA
ProSource ZMA is the same SNAC Systems formula used in that study. When it was time to add a maximally effective ZMA product to our ProSource line, we knew right where to go for the absolute-best, ultra-premium grade zinc-magnesium aspartate. SNAC (Scientific Nutrition for Advanced Conditioning) Systems has long been the leader in ZMA research and formulation. This should not be surprising given the fact that SNAC pioneered, formulated and introduced the very first ZMA product. In keeping with its research criteria, SNAC uses only the best zinc, magnesium aspartate and vitamin B6 in the exact ratios shown to be effective in clinical trials. It’s important to note that many similar products out there are not the same studied SNAC System formula.

A Powerful Synergy
It should also be noted that zinc and magnesium each play important roles in optimizing performance and recovery. Strenuous physical exercise causes significant increases in the loss of zinc in the urine, and studies have shown that even small deficiencies in zinc can lead to reductions in testosterone production. There is also evidence that zinc has antioxidant activity, so it may help fight free radicals generated during exercise that can hinder recovery. Finally, there is evidence that zinc deficiency is related to under-production of insulin like growth factor 1 (IGF-1), a potent anabolic hormone. As for magnesium, a Western Washington University study indicated that subjects taking a magnesium supplement following a seven-week leg-training program increased their leg strength by 20% compared to those taking placebo.

An Unrivaled Value
As if this isn’t enough, ZMA is also one of the most affordable T-boosters on the market. Though it doesn’t have the unprecedented T-boosting power of an advanced technology like ProSource's ZMA, it does have a great price, proven performance results and premium quality ingredients, so it’s no wonder ZMA holds strong in this category. It works perfectly as a stand-alone or can be incorporated into other supplementation regimens for added effect. Combat zinc and magnesium deficiencies, help boost testosterone levels and increase your strength and growth potential with this immensely popular anabolic agent.

"Helps with deep restfull sleep" - Darcy

"I just started using this for a steady week now and I feel the difference, a good product even for the not so serious lifter!" - CHESTER A

"I have been training for over 40 years now and I was looking for a natural way to have better sleep, but most of all to restore my testosterone levels and finally got it with ZMA along with Dopa Tech HGH during night time. I checked my Test levels in a lab and got astonishing results. Really recommended." - A great product.

"Wouldn't think about going to sleep without it. Be prepared for the occasional vivid dream." - DUNHAM

"This is my 2nd bottle and have ordered another one. Helps me sleep great and reduces soreness. Only bad thing is I wake up and my mouth is so dry it is unreal. Other than that it's great" - Caleb

"Good product. Sleeping great" - DARREN

"I'm on my second bottle and since I've started taking ZMA I sleep like a baby through the night. I also noticed I have more energy and it aids in my recovery after a hard workout.

"Some supps we take simply because of the science. Especially when the low cost makes them so accessible. Certainly many bodybuilders know this. It is impossible to differentiate (in many cases)the specific results of each supplement when we are regularly stacking a dozen items or more. In my view, ZMA is a must for any serious fitness enthusiast and/or bodybuilder." - Richard W.

"I work 8 to 10 hours a day six days a week running heavy equipment, farm on the side, have 3 young kids and workout at least 3 times a week so needless to say I don't get anywhere close to the 8 hours of sleep. When I take ZMA I feel like I've had 8 hours of rest when I've only had 5. I have noticed a small gain in the gym but a good nights sleep is worth every penny!" - CODY

Definitely some T support too, so be aware of that." - DAVID
