Quick Take: Universal Nutrition ZMA Pro is a throwback to the original ZMA stack back in the 90s. I like how it promotes deeper sleep, recovery, and testosterone. However, I do believe its benefits could be felt much better with a few tweaks here and there. Let’s get this review started and find out if this is the supplement that best fits YOU.
- ZMA Pro is a product of one of today’s oldest and biggest supplement companies: Universal Nutrition
- Advertised to contain “a precise and specific combination of unique forms of zinc, magnesium and vitamin B6”
- Follows the exact formula used in the original ZMA stack back in 1999
- Effective for most people but more importantly, on athletes who are in dire need of better nutrition
- Promotes sleep and higher testosterone which should result in better muscle growth, too
- Available to buy online and in retail stores including Amazon, iHerb, Bodybuilding, and the official Universal USA website.
Universal Nutrition ZMA Pro Ingredients
|Vitamin B6 (As Pyridoxine HCL)||10.5 mg|
|Zinc (As L-Monomethionine And Aspartate)||30 mg|
|Magnesium (As Aspartate)||450 mg|
Universal Nutrition ZMA Pro – Ingredients Review
Vitamin B6 – As Pyridoxine HCL, Universal Nutrition ZMA Pro doesn’t have the best form of Vitamin B6 (P-5-P is). Regardless, there’s rat research showing B6 depletion leading to lower levels of testosterone. As such, I think it’s great that this supplement provides a hefty 10.5 mg dose.
Zinc – Involved in the actual synthesis of testosterone, Zinc may perhaps be the most essential mineral for T. Furthermore, it also helps maintain test levels after exercise which, according to research, would then benefit the performance of athletes. Both dosage and form(s) are great here on ZMA Pro, too.
Magnesium – Like Zinc, the Magnesium used here on Universal Nutrition ZMA Pro is attached to the Aspartate amino amino acid. This make it easier to absorb and therefore more potent than its cheaper counterparts (e.g., oxide, sulfate). On that note, the ease of absorption also makes this 450 mg dosage quite solid. For male health, Magnesium inhibits SHBG leading to higher levels of “free” testosterone. It also promotes sleep and recovery making it great for bodybuilding.
Before we move on, you might be wondering that SHBG and “free” testosterone is. Let’s talk about them real quick.
SHBG stands for Sex Hormone-Binding Globulin. As its name suggests, it binds hormones such as testosterone to it. In fact, an estimated 30-40% of your total testosterone is bound to SHBG.
What does this mean? Why is this even important?
Well, in essence, any hormone that’s bound to SHBG becomes useless. Since 30-40% of your testosterone is locked behind the figurative bars of SHBG, that same amount of T is useless, too — THIS IS WHY NATURAL SHBG INHIBITORS SUCH AS MAGNESIUM ARE IMPORTANT.
By blocking or weakening the binding prowess of SHBG, Magnesium effectively frees some of those bound testosterone so your body has more of the anabolic hormone to use.
Universal Nutrition ZMA Pro Directions
Each serving of ZMA Pro consists of 3 capsules. However, as per Universal Nutrition, men and women should take this supplement differently.
- For men
- Take 3 capsules daily
- For women
- Take 2 capsules daily
The trio of Zinc, Magnesium, and Vitamin B6 have been commonly found in the supplements stacks of athletes and men and women who’re serious about fitness. As a whole, these nutrients are collectively known as ZMA. Thus, this product’s name, ZMA Pro.
Circa 1999, Victor Conte and his company (BALCO Labs) marketed what may be the first iteration of ZMA. From then on, ZMA’s popularity has been on the rise. Fast forward to today, 2018, many supplement manufacturers have now made their own upgraded versions of this legendary trio (like EVLUTION Nutrition’s Z-Matrix or NOW Sports’ ZMA, for example).
Universal Nutrition, however, is one of several companies who remain loyal to the original ZMA blueprint. As such, they used the same exact formula that got Zinc, Magnesium, and Vitamin B6 on the map in the first place. That being said, I think that, for better or for worse, it’s just as effective.
Like the original, Universal Nutrition ZMA Pro is designed to help athletes get better sleep while also promoting higher testosterone. In theory, these effects help your muscles recover faster as well. Taking into account the track record of Universal Nutrition, the overwhelming ratings and reviews of ZMA Pro itself, and the sheer design of this formula, I believe Universal Nutrition has done a good job on ZMA Pro regardless of being a copy of the original.
Universal Nutrition ZMA Pro Benefits: Does it Work?
Short answer: YES, Universal Nutrition ZMA Pro works.
Long answer: YES, it works but NO, it’s not for everyone. Allow me point you to a couple of studies to help explain what I mean.
According to a research conducted by Victor Conte himself, ZMA supplementation increased “free” testosterone, growth factor, as well as muscle strength and size. Moreover, the same research also points out that most athletes typically have depleted levels of Zinc and Magnesium due to exercise, sweat, and inadequate dietary intake.
On the other hand, another research on ZMA concludes that “ZMA has no significant effects regarding serum testosterone levels and the metabolism of testosterone in subjects who consume a zinc-sufficient diet”. Overall, both these studies are saying that yes, ZMA works on a majority of people but if you already have enough Zinc, Magnesium, and/or Vitamin B6, it won’t do you much good.
Universal Nutrition ZMA Pro Review Summary
- Non-proprietary – If there’s one thing ZMA Pro has that a lot of other supplements don’t, it’s an honest formula that doesn’t hide specific dosages.
- Effective – For most people, that is.
- Reviews and ratings – Wherever I check, be it Amazon, iHerb, or Bodybuilding, Universal Nutrition ZMA Pro has impressive reviews and ratings. Not a lot of reports regarding side effects either.
- Inexpensive – Prices vary wherever you buy it but Amazon and Bodybuilding(.)com sells this for a little less than 14 bucks.
- No upgrades – A couple more ingredients would’ve made this stack better. For instance, melatonin and L-Theanine could’ve also helped with sleep and BioPerine® could’ve bolstered absorption.
- Vitamin B6 – Not that it’s a bad ingredient (it’s not) but P-5-P would’ve been a better form than Pyridoxine HCl.
- Uhh, that’s it. I got nothing else.
The Bottom Line
In summary, Universal Nutrition ZMA Pro uses the same exact formula as the original ZMA blend. In a way, this is a good thing because these particular combinations of nutrients, forms, and dosages have been historically proven to be effective for most men and women. However, I personally would’ve liked it better with a few tweaks. A few more complimentary ingredients and better forms, to be exact. Do I think it’s one of the best testosterone supplements in the market? Far from it. For a sleep and recovery testosterone booster though, I think it does alright.
