Product Overview


Intense training may lower levels in your body of vital nutrients and minerals. Many of these minerals you may not be getting enough of without the use of a supplement. MET-Rx® ZMA is a unique mineral support formula containing bioavailable forms of Magnesium and Zinc, including Zinc L-Monomethionine.*

Why is Zinc so important?

Zinc is an important mineral beneficial for male physiology by supporting reproductive health as well as being involved with carbohydrate, protein, fat and energy metabolism.* It is involved in the synthesis of collagen in bone tissue and is essential for cell division and growth.* Zinc plays a role in over 300 enzymes in the body and forms an important part of the structure of carbonic anhydrase, an enzyme found in red blood cells.* This enzyme serves to accelerate the reaction between a mole of CO2 and water per mole of enzyme to a rate 5,000 times faster than would occur without the enzyme, and therefore plays an important role in carbon dioxide removal from the bloodstream. Zinc also helps with immune function – so make sure you are getting enough of this important mineral every day.*

Why is Magnesium so important?

Magnesium is vital factor in energy production (ATP) and muscle contraction.* It’s needed for many reactions in the muscle, including creatine kinase activity, actin-myosin binding, Na/K+ pumps and calcium pumps.* Magnesium also helps to regulate calcium transport and plays an essential role in maintaining bone mineralization.* When Magnesium levels are insufficient, neurons may fire too easily, resulting in excessive sensitivity to various stimuli. Its presence in adequate amounts in the synaptic gap between neurons helps control the rate at which nerves fire.* Not getting enough Magnesium may deflate your workouts.

Why is Vitamin B6 so important?

Vitamin B6 promotes the production of red blood cells which plays a role in energy metabolism/conversion.* B6 also helps promote healthy levels of homocysteine already within a normal range and supports heart health.* Vitamin B6 acts as a cofactor to an enzyme required for aspartate metabolism and is essential for BCAA metabolism.* The Vitamin B6 coenzyme is necessary for processing amino acids, and, in turn, protein; yet is also involved in carbohydrate metabolism.*

When looking for a supplement to help with many factors of your health and fitness which will help you reach your goals, look no further than MET-Rx® ZMA!

Use with an intense daily exercise program and a balanced diet including an adequate caloric intake.


There is a difference between looking big and being strong. True strength takes dedication.

Updating from my original rating of 5/10. I have since taken this ZMA product again and I do believe it is working for me in a positive way. I don't feel so good that I'll rate it a 10 but I do think that my sleep has improved with consistent use of this and timing it right in my evening routine.

ZMA is definitely a staple in anyone's arsenal when trying to bulk or shred. Gives me a great sleep and feel refreshed in the morning. I see a huge difference when on and off this.

With this product, there was some increased testosterone levels and better quality of sleep. However, I did not have any problems with sleeping before or with T-levels so I can't say for certainty that it is definitely the ZMA.

it works but not that good. i take 2 caps 30 mins prior to bed,though it says take 3 caps with meal perfectly. sleep like like hamered with vivid not-so-good dream,nightmare sometime. waking up next morning just like every other dayz, no any obivious differs nor my T-level or strength increased. so far it dose the melatonin job well.

Great product and very effective. Not all ZMA is the same even though the labels might read similar. Helps me get into a deep restful sleep. This product works better than others, so much so, that I only take 2 capsules at night. Highly recommended.

I read all the verified reviews of this product before purchasing to help me make a decision. I can say that a lot of the comments regarding active dream states holds true with me as well. Not quite like lucid dreaming, but I definitely have vivid dreams that I can remember upon waking up. The most important thing though is the sleep quality it allows me. I use a Jawbone UP and since using Met-Rx ZMA I see a HUGE difference in the quality and length of my sleep. Before i would average 6.5 hours of sleep a night with numerous times of waking up. Since I've started taking this I've been averaging over 8 hours of sleep and the times I'm waking up during the night have decreased dramatically. Excellent product!

I'm fairly pleased with the product. From a sleep perspective, this ZMA definitely knocks you out and puts you into a deep sleep. When waking up, I am a little groggy & do feel I need a few minutes to full become sharp which I haven't necessarily felt before taking this. I can't say that the product is attributing to any recovery, I do intense weight training early morning and cardio and night, and soreness is still fairly present. for assistance with sleep, I highly recommend this product especially for the price.
