Product Overview

Bodybuilding.com Signature ZMA

A good night’s sleep is key to your overall health — and your goals in the gym. Without proper sleep, your body can’t repair itself. Signature ZMA is a patented blend of zinc, magnesium, and B6. Clinical research has shown that this ZMA blend, when given to trained athletes before bed, may support improvements in sleep quality, strength, power, and testosterone levels.[5]* Zinc and Magnesium both also play vital roles in hundreds of bodily functions necessary to performing your best while Vitamin B6 supports their absorption.*

ZINC

Zinc is important to countless processes in the body, including immune function[3,4] and protein synthesis[4].* Thanks to your high-intensity training, sweating and insufficient zinc intake, athletes like you may have lower stores of zinc in the body —so supplementing is often necessary just to meet the basic zinc requirements, let alone optimal levels for peak performance.*

Magnesium

Magnesium helps regulate factors that are especially important for active individuals: protein synthesis, muscle and nerve function, blood glucose control, and blood pressure regulation[1-3], just to name a few. It's required for energy production and contributes to the structural development of bone. When it comes to athletic performance, magnesium supports nerve impulse conduction, muscle contraction, and normal heart rhythm[3].*

Vitamin B6

Vitamin B6 in coenzyme form is involved in more than 100 enzyme reactions in your body, mostly concerned with protein metabolism[1]. It’s also key to this ZMA blend because helps your body to absorb zinc and magnesium more effectively.*

A signature is a promise. A symbol of your identity. Your mark on the world. In 1999, Bodybuilding.com was founded on a single promise: Trust. It’s who we are and it’s in our blood. Our Signature line is built on the same promise. Every product is no-BS, transparent, filler-free, and formulated with effective doses of research-backed ingredients you can trust. We create the highest quality supplements, so you can focus on leaving a mark of your own.

I was restless every night I took this. The only reason I giving it a 7 is when my wife used it, she felt rested by the time she woke up. I just flopped around like a fish. As I look at other reviews it seems as if this is something for women. Looks like they are have better results from this product.

I’m on bottle number five? But I purchase these non stop. I need a back up just in case! I get on average 4/5 hours of sleep every night. I love that these make me feel so well rested, never groggy! Remember it doesn’t PUT you to sleep, it helps promote healthy sleep. A great staple to everyone’s nighttime routine!

Does not help me sleep at all, in fact, it does the opposite for me. I had to stop taking it because i was laying in bed for hours without falling asleep. Took it every night for about two weeks to see if things would change, but nothing did.

Still getting the feel of these ZMA's. Sometimes nights I sleep well. Others, I don't. Not sure if I am getting the quality of Magnesium, Zinc and D. I will follow up later when I am done with My second bottle.

I have tried almost two bottles worth. There is no benefit, at all, that these pills provide for me. I purchased them to help me sleep. Everything else it said it does was just gong to be a bonus. They didn't do a thing to help my quality of sleep. As for the other so called "benefits", I didn't see effects. When I told a friend, who is a nurse practitioner, what I was talking, she said, "How is that supposed to help you?" Don't be a gullible consumer like me. Do not purchase these money wasters.
