    ZMA JYM is an advanced recovery-enhancing supplement with precise amounts of two key minerals – zinc and magnesium – shown to help optimize hormone levels and support muscle strength. ZMA JYM’s third major ingredient, vitamin B6, can aid zinc and magnesium utilization by the body.

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


    Research suggests that many athletes are deficient in both zinc and magnesium. This may be 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 help promote help 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 in healthy men. 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 an increase in testosterone levels, and an increase in levels of insulin-like growth factor 1 (IGF-1). Those taking a placebo had a decrease in testosterone levels and a 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.


    ZMA is not just zinc, magnesium, and vitamin B6 thrown into a bottle. Real ZMA is licensed only from SNAC Systems, Inc. and contains B6 and specific forms of zinc and magnesium that help enhance their uptake by the body.

    Look for only real ZMA SNAC System, Inc.


    Some other zinc products actually add other minerals to the formula. Two common minerals you may see are copper and calcium. This is counterproductive because calcium can interfere 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 the black pepper extract, BioPerine.
