Product Overview











ZMA JYM is an advanced recovery-enhancing supplement with precise doses of two key minerals – zinc and magnesium – shown to help optimize hormone levels and maximize muscle strength and size. ZMA JYM’s third major ingredient, vitamin B6, can aid zinc and magnesium utilization by the body, while also helping provide fuel for the muscles.*

Often taken before bedtime to promote a better night’s sleep and muscle recovery, ZMA JYM is the most effective way for athletes and other hard-training individuals to get adequate zinc and magnesium for the best possible results from their workouts.*



Research has confirmed that many athletes are deficient in both zinc and magnesium, which is due to several factors. This is due to several factors that increase the loss of these critical minerals and also decrease their uptake from food.

Loss of these minerals occurs through sweat and urine, plus an increased use for recovery and protein synthesis. Reduced uptake of these minerals can also occur when consuming refined sugars and white-flour products, alcohol, calcium-rich foods like dairy, copper, as well as foods rich in phytates (phosphorous compounds found in whole-grain breads, cereals, and legumes).

ZMA JYM is designed to work with Vita JYM, which purposely doesn’t include zinc and magnesium, to promote better absorption of other critical vitamins and minerals and prevent you from getting too much zinc and magnesium.



Research suggests that ZMA has significant anabolic benefits. A study performed at Western Washington University (Bellingham) had NCAA football players take ZMA or a placebo every night during an eight-week spring training program. Researchers reported that the athletes taking the ZMA supplement experienced more than a 30% increase in testosterone levels, and about a 5% increase in levels of insulin-like growth factor 1 (IGF-1). Those taking a placebo had a 10% decrease in testosterone levels and a greater than 20% decrease in levels of IGF-1!



In addition to the improvements in their anabolic hormone levels, the ZMA-supplemented athletes in the aforementioned study made significantly greater gains in strength and power, and achieved better sleep quality, than the placebo group. Better sleep quality helps promote muscle recovery from tough workouts.*



Several other studies also suggest that zinc and magnesium offer potent anabolic properties.*

One study from Selcuk University (Konya, Turkey) reported that four weeks of zinc supplementation in men increased testosterone levels at rest and after exercise. The same researchers also found similar results for zinc supplementation on testosterone levels in a prior study with competitive wrestlers.*

On the other hand, researchers from the USDA reported that zinc depletion decreased muscle endurance in subjects. This means that maintaining optimal zinc levels is critical for your ability to complete a number of reps with a given weight.*

The same Western Washington University team that performed the aforementioned ZMA research discovered in an earlier study that, when subjects supplemented with magnesium while following a seven-week leg training program, their leg strength increased by 20% more than those taking a placebo!*



ZMA is not just zinc, magnesium, and vitamin B6 thrown into a bottle. ZMA is specific forms of these minerals that enhance their uptake and utilization by the body. ZMA specifically uses zinc mono-L-methionine, and aspartate and magnesium aspartate. This is critical, because there are two forms of zinc monomethionine: zinc mono-L-methionine and zinc mono-D-methionine. Only the “L” form is readily absorbed and used by the body. The human body is not able to use the “D” form.

Some bogus ZMA products use a combo of both the “L” and “D” form. The D form actually inhibits the absorption of the L form and undermines zinc uptake. If a ZMA product does not specifically list zinc mono-L-methionine, and instead lists zinc monomethionine, don’t bother with it. An easy way to ensure that a product uses real ZMA is to look for the SNAC System trademark listed on the bottle.



Many ZMA products actually add other minerals to the formula. Two common minerals you may see are copper and calcium. This is counterproductive because calcium interferes with zinc uptake, as does copper. As critical as these minerals are, you should be taking them at separate times of the day, not with your ZMA.

I formulated ZMA JYM to optimize the body’s uptake and utilization of zinc, magnesium, and vitamin B6. That’s why the only thing I added to ZMA JYM is BioPerine®. Research shows that this black pepper extract can enhance the absorption of zinc, magnesium, and vitamin B6 by the body.*



While it’s easy to look at a single ZMA product, or any product for that matter, and decide whether you want to add it to your supplement regimen, you need to consider ZMA JYM in relation to my other products. ZMA JYM is designed to work in combination with Vita JYM and Pro JYM to provide all your critical micronutrients in the proper forms and doses at the specific times you need them.

As mentioned, Vita JYM is strategically devoid of zinc and magnesium because you want to supplement those two minerals as ZMA at a separate time from other minerals. Plus, you don’t want to supplement with too much zinc or magnesium, which is counterproductive.

Vita JYM also intentionally leaves out calcium, which interferes with the absorption of numerous minerals. To make up for this, my high-quality protein blend Pro JYM provides ample calcium (400 mg per serving).

This is the way I designed all my JYM supplements: to work hand-in-hand with one another and deliver the best possible results as a complete system. The JYM Supplement Science line is the smartest, most effective supplement line on the market. I wouldn’t create anything less for myself or for you.

I love this product as most multivitamins add zinc and magnesium. Your body can’t, or doesn’t process these two with other vitamins and minerals. This is not a sleeping pill it helps your body get all of the nutrients you need at the right times.
