ZMA Jym by Jym Supplement Science Review – Is It One of the Good Post-Workout Supplements or Not?

What Is ZMA Jym?

ZMA Jym is a multi-mineral supplement that helps athletes and bodybuilders to optimize their hormone levels and to build and maintain muscle mass. This is done through providing bioavailable forms of zinc and magnesium that are blended with vitamin B-6 and black pepper extract to help increase the body’s ability to absorb and use them.

This supplement is most effective when taken on an empty stomach. Ideally, it should be taken at least one hour before or after eating a meal. Alternatively, many men choose to take it thirty to sixty minutes before going to bed to enhance the quality of their sleep, which is a helpful lifestyle choice for those who are bodybuilding. It is also important for consumers to be aware that if they are taking other supplements in the Jym line, these will need to be taken at different times of day to avoid their ingredients interfering with the ingredients in this product.



ZMA Jym is manufactured by JYM Supplement Science. This company was co-founded by Dr. Jim Stoppani for the purpose of developing a supplement company which is science-based. Dr. Stoppani has a proven track record for scientific research, receiving his PhD in Physiology (with a minor in biochemistry) from the University of Connecticut and later working at Harvard’s John B. Pierce Laboratory of the Department of Chemistry and Molecular Physiology. This is one of the few companies which does base the manufacture of its products on scientific reviews and studies in order to come up with the best and most effective supplements possible.

In the Mission Statement on the Jym Supplements Science website, Stoppani lists the following goals/visions for his company:

  • To make supplements that he himself would trust and feel confidence in.
  • To set a standard in the supplements industry for quality by using the best ingredients available and for transparency by listing every single ingredient on the bottle so that consumers will know what they are buying.
  • To encourage the use of scientific research when formulating specific supplement blends.
  • To lead the way in the formulation of high-quality, non-proprietary blends of supplements with the ideal ingredients in their proper dosages.
    To increase general standards of accountability and accessibility in the supplement industry.
  • This commitment to quality and transparency – along with the scientific backing for the formulation of supplement blends – should make consumers feel more comfortable with their purchase.


How ZMA Jym Works?

One of the things which sets ZMA Jym apart is that it is backed up by an array of clinical studies. The science behind ZMA supplementation is actually pretty simple. Athletes and bodybuilders demand a lot from their bodies – and this quest for a strong and sculpted muscles can often lead to depleted levels of zinc and magnesium in particular. There are actually a number of ways this can happen – and a number of reasons why athletes are more at risk for this problem.

These minerals can be depleted through sweat or urine. Considering the amount of sweat lost in an average workout, it is easy to see how much could potentially be excreted through sweat alone. They are also taken up in greater quantities by bodybuilders and others who are very physically fit due to the increased need for them to build proteins and allow muscles to recover. However, this means that the harder the workout, the greater the risk for minerals to be lost.

Nutrition is also a factor. Most people who are serious about bodybuilding eat very healthy diets and are conscious of the importance of good nutrition. However, athletes who make certain dietary choices – such as including alcohol, refined flours and sugars or foods rich in calcium or phosphorous (such as whole grains or legumes)in their diets – can put themselves at risk for even more zinc and magnesium depletion. And studies have linked low zinc and magnesium levels to a decrease in muscle mass, the last thing someone wants when they are trying to get and stay in shape. This is why it is such an important issue to be aware of.

ZMA Jym can prevent this mineral depletion from happening by giving top athletes the nutrients they need. This product works by combining important minerals with vitamins and black pepper extract to enhance the bioavailability of zinc and magnesium and thus increase their uptake by the body. This can help athletes to enhance athletic performance by increasing levels of certain hormones and by building more muscle mass.

For example, in a study out of Western Washington University, NCAA football players on the ZMA supplement showed a 30% increase in testosterone and a 5% increase in insulin-like growth factor-1 (IGF-1 for short). This was in comparison to athletes in the control group who took placebos: they actually presented with a 10% drop in testosterone and an almost 20% decrease in IGF-1. The group on the ZMA supplement also demonstrated an increased in muscle strength and better sleep quality, which is important for muscle recovery.

This same NCAA football team, in an earlier study, took magnesium supplements while participating in an intensive 7-week leg training course and found that their leg strength increased by 20%.

These are not the only study to associated these minerals with increased levels of testosterone. In another study from a university in Turkey, men who used a ZMA supplement for 4 weeks showed an increase in testosterone levels both at rest and after working out.

The ease with which these important minerals can be depleted – and the decrease in muscle mass which can result – make supplements like ZMA Jym a key part to any successful bodybuilding regimen.


Ingredients of ZMA Jym

It is the blend and quality of ingredients that gives ZMA Jym its edge and makes it such a good choice for those interested in achieving a lean, muscular body. This supplement contains:

  • 10.5 mg of vitamin B-6 in the form of pyroxidine HCl – this is 525% of the daily value;
  • 450 mg of magnesium in the form of magnesium aspartate – 113% of the daily value;
  • 30 mg of zinc in the form of zinc mono-L-methionine and aspartate – 200% of the daily value;
  • 5 mg of Bioperine, a patented black pepper extract.

These ingredients are high quality and sourced with care. However, no vitamin or mineral will do the body any good if it cannot be readily absorbed. That is why ZMA Jym has been specifically designed with bioavailability (a measure of how readily the body can absorb a certain nutrient) in mind.

The particular forms of these nutrients were carefully chosen to maximize the ease with which the body can absorb and utilize them. Of all of these, the most important consideration is the zinc. Zinc can come in two different forms – zinc mono-L-methionine and zinc mono-D-methionine. It is important not to buy supplements with the “D” form, since the body cannot absorb it. The B-6 is present in order to enhance the body’s ability to use both the zinc and magnesium and the patented Bioprine mixture contains piperine, an active compound which helps with nutrient absorption.

The two main ingredients are both needed to meet the particular needs of bodybuilders. Zinc is used so in the process of building proteins, which in turn are needed for the production of muscle mass. It has been shown in multiple studies to increase testosterone levels in men. Magnesium is needed for the health of the cardiovascular system and for a strong metabolism, as well as for getting deeper and healthier sleep to give muscles a chance to rebuild in between workouts.

It’s also important to mention what ingredients this supplement does not contain. For one thing, there are no herbs that can boost testosterone; this is because these herbs can sometimes interfere with the body’s ability to take in and use zinc and magnesium. There are no other minerals in this supplement – especially not copper or calcium – because they can inhibit the absorption of magnesium and zinc. Other products in the Jym line of nutrients do contain these minerals (as they are important, too), but these supplements are meant to be taken at different times of the day so that they do not interfere with one another.

There are also no sleep enhancers in ZMA Jym as there are in other ZMA formulas. Many athletes will use sleep supplements such as melatonin, valerian or 5-HTP. However t the everyday use of them, especially over a long period of time, can cause dependence. Even so, most people who use this product do report sleep improvements, since magnesium can naturally improve the quality of sleep without the possibility of dependence.



There are many advantages to this product that have made it attractive for a large number of customers. For one thing, it comes in easy-to-swallow capsules that should be taken three times a day. In short, there are no messy powders to mix or liquids to drink down! Its unique blend of minerals come in forms that maximize their bioavailability – which also maximizes their benefit. It works with other Jym products, including VITA Jym and Pro Jym to provide the body with the full array of nutrients that it needs to build lean muscle mass.



There are no specific certifications for this product, but it has won a number of awards and has received excellent testimonials from clients around the country and the world who have experienced the difference this supplement can make in their workout regimen.



Testimonials are one of the best ways to determine if a workout supplement might be worth a try: who better to learn about a product than from other athletes and bodybuilders who have used this product for themselves?
