Evlution Nutrition Z-Matrix Review (UPDATED)

About Evlution Nutrition Z-Matrix

Today we’re taking a look at the Z-Matrix supplement by Evlution Nutrition. It’s a “Nighttime Performance Recovery” support made to help you have good quality sleep, and better overall performance in the gym.

Evlution Nutrition Z-Matrix is also a ZMA formula supplement. Among its ingredients, which are all-natural, it contains zinc and magnesium. These two minerals are included to help you with protein synthesis and with elevating testosterone levels.

So right off the bat, we can see that Evlution Nutrition Z-Matrix is a supplement that not only aims to promote deep sleep. But also to elevate testosterone levels and enhance your performance in the gym.

But how effective is this product at doing what it claims? Let’s look up close at its ingredients to see if they work and are dosed correctly.

How to Use Evlution Nutrition Z-Matrix

Each serving of Evlution Nutrition Z-Matrix is 4 capsules. For optimal use, you are to take one serving of the product 30-60 minutes before sleep.

One bottle, which costs around 15 dollars, has 120 capsules in it. So if you’re following the use instructions, this means one bottle of Evlution Nutrition Z-Matrix will last you 30 days. I’d say that’s a fair bargain!

Also, the product doesn’t have any stimulants or artificial active ingredients, so you can start with a full dose straight away. However, be careful when taking Evlution Nutrition Z-Matrix on an empty stomach. For some people, magnesium and zinc can cause gastrointestinal issues, headaches, or nausea. So I’d recommend taking Evlution Nutrition Z-Matrix with the dinner or right after the dinner.

The Ingredients

All of Evlution Z-Matrix’s ingredients and their dosages are disclosed, which is always nice to see! Also, a big plus is that all of its active ingredients are natural. This is important because it’s never good to put chemicals in your body – natural is almost always a better option!

evlution nutrition z-matrix ingredients

Among other ingredients, aka, fillers, we have; Rice Flour, Gelatin, Vegetable Magnesium Stearate, and Silicon Dioxide.

I don’t like seeing Magnesium Stearate here, as it can lessen the bioavailability of other ingredients. Fortunately, Black Pepper Extract (which is among the active ingredients) should be able to offset this.

As for the active ingredients, Evlution Nutrition Z-Matrix has 7. See them for yourself:

Magnesium (Magnesium Aspartate) 

Magnesium is an essential mineral which plays an important role in many functions of the body. Some of those functions include supporting heart, nerve, and muscle function. The latter is probably the one you’re wondering about, and I can tell you that if you’re magnesium deficient. This will help you get a better quality sleep, and give you more energy in the gym. (magnesium study: https://www.ncbi.nlm.nih.gov/pubmed/19095394)

Zinc (Zinc aspartate and mono-l-methionine) 

Very important for regulating various enzymes in the body. It also plays a key role in regulating your immune function and keeping your testosterone levels at where they should be. However, if you aren’t deficient in zinc, taking it won’t really do much for you. (study: https://www.ncbi.nlm.nih.gov/pubmed/8875519)

Folic Acid

Folic Acid supports protein synthesis in the body, but it has no impact if you already consume a diet which has this vitamin. And chances are, you do, as folic acid is found in abundance in many foods.

Vitamin D3 

I always love seeing vitamin D in testosterone-boosting supplements. Many people are deficient in this vitamin, and it can really help balance those testosterone levels. But I have to say I was disappointed when I saw the dosage of this vitamin – only 500 IU (International Units). Unless you’re exposed to the sun at least 15-20 minutes every day, this is not enough vitamin D to significantly affect your testosterone levels. Based on our research, a minimum of 3000 International Units of vitamin D is required daily to push testosterone production. See more on Vitamin D and its optimal dosage here: https://examine.com/supplements/vitamin-d/

Vitamin B6 (Pyridoxine HCl)

Vitamin B6 works in conjunction with folic acid. Alongside helping with protein synthesis, it also enhances the absorption of zinc and magnesium. However, just as with folic acid, it’s unlikely that you’re deficient in this vitamin, therefore you might not notice any benefits.


One of my favorite ingredients in this product. Naturally found in green tea, L-Theanine promotes relaxation, deep sleep, and focus without causing any drowsiness. It’s often supplemented alongside coffee to prevent those infamous jitters and crashes from caffeine. Also comes with a nice dose of 200mg, which is just enough to fully experience its effects. In terms of fitness, L-Theanine may help you get deeper sleep, thus enhancing your muscle recovery. More on Theanine here; https://examine.com/supplements/theanine/

BioPerine (Black Pepper Extract)

Increases the bioavailability of other ingredients. Having black pepper extract added in a supplement is always a plus. If you want to know more, see this link: https://examine.com/supplements/black-pepper/

EVL Z-Matrix Side Effects

As long as you follow the instructions on the label of Evlution Nutrition Z-Matrix, you shouldn’t notice any adverse effects from taking it. That being said…

While most people didn’t report any issues, there are a few cases of side effects such as:

  • Tingling feeling on the skin
  • Nausea
  • Headaches.

These side effects are mainly the result of the high doses of vitamin B6 that are in the supplement. If you already consume a lot vitamin B6 through foods like vegetables, meat, and/or dairy. Be careful when taking the full dose of Evlution Nutrition Z-Matrix. It’s possible that high doses of Vitamin B6 could cause you some of the side effects I mentioned above.

In my opinion, Evlution Nutrition Z-Matrix would do a much better job putting a natural testosterone boosting ingredient instead of vitamin B6 and folic acid, as these vitamins are already found in abundance in various foods.

Pros and Cons

Evlution Nutrition Z-Matrix is a good product for improving sleep. It has L-Theanine and magnesium, which can help you relax and give you better quality sleep. But when it comes to increasing testosterone, it’s a different story.


  • Natural active ingredients
  • L-Theanine and Magnesium can help you sleep better, and achieve better muscle recovery from workouts. They also come in effective doses.
  • Affordable – 15 dollars for an entire month’s supply


  • Magnesium Stearate can hinder the bioavailability of other ingredients. I.e. it can prevent your body from absorbing all of the ingredients that are in Evlution Nutrition Z-Matrix.
  • Folic Acid and Vitamin B6 are found in many different foods, and are not needed in a supplement. Unless you’re seriously deficient in these vitamins, there is no benefit from taking them as a supplement.
  • Low dose of Vitamin D3 – 500IU is just not enough to have a significant impact on your testosterone.
  • Evlution Nutrition Z-Matrix only has one ingredient which could boost your testosterone – zinc. And if you aren’t deficient in zinc, you won’t get any benefits from taking it.
  • High doses of Vitamin B6 could potentially have negative side effects

Conclusion to Evlution Nutrition Z-Matrix Review

Evlution Nutrition Z-Matrix can be a good product if you have insomnia, or just want to get a deeper sleep. However, for boosting testosterone, there is a lot of room for improvement. Having only Zinc and Vitamin D3 as its testosterone regulating ingredients (not to mention the low dose of Vitamin D3) will hardly have any impact on your hormone levels, and muscle mass.

That leads me to a conclusion that if your goal is to increase your testosterone, and ultimately, muscle mass. I would steer away from Evlution Nutrition Z-Matrix. There are better options out there. It can be hard to choose the right supplement with so many options, which is why we reviewed the Top 3 Testosterone Boosters currently on the market – you can see them by following the link below.

Evlution Nutrition Z-Matrix is good if you want to improve sleep quality. But if you want more than that, that’s where this supplement fails to deliver. Make sure to evaluate your options and see if Evlution Nutrition Z-Matrix can help you with what you’re looking for.
