ZMO, which stands for Zinc, Magnesium, & Oyster Meat, is a revolutionary nighttime testosterone-support and muscle-recovery supplement designed specifically with athletes, bodybuilders, and gym-goers in mind. Magnesium and zinc play key roles in androgen production, libido, muscle recovery, sleep quality, and overall wellness. In addition, oyster meat in ZMO is a natural aphrodisiac and rich source of 60+ trace minerals that help optimize the many biological functions of macrominerals like magnesium and zinc.


The catch is that traditional ZMA (zinc magnesium aspartate) supplements contain inferior oxide and aspartate forms of magnesium and zinc, rendering them ineffective due to poor absorption. We formulated ZMO with highly bioavailable magnesium bisglycinate and zinc picolinate so your body can properly absorb and utilize these crucial minerals.

Why Use ZMO

ZMO is an advanced nighttime supplement for enhancing testosterone production, muscle recovery, sleep quality, and overall vitality.

Supports muscle protein synthesis and recovery, helping muscles repair faster after training.

Support Healthy Testosterone Levels

Clinically studied zinc and magnesium encourage healthy testosterone production and hormonal balance, promoting overall vitality.

Improve Sleep Quality

Bioavailable magnesium bisglycinate promotes restful, deep sleep, essential for optimal recovery and daily energy.

ZMA Evolved

Formulated with superior zinc and magnesium sources, ZMO is the evolution of ZMA supplements.

Key Ingredients

Our formulas are made with clean, natural ingredients, with clinically-validated dosages to support health and performance.

Magnesium (from Magnesium Bisglycinate Chelate)

120 mg
Highly bioavailable, non-laxative magnesium form that supports testosterone levels, sleep quality, insulin sensitivity, stress reduction, and overall health.

Zinc (from Zinc Picolinate)

11 mg
A bioavailable zinc source for maintaining healthy testosterone levels, thyroid function, metabolism, and overall performance.

Oyster Meat Powder

500 mg
Naturally rich in zinc, magnesium, and essential trace minerals, oyster meat supports testosterone levels, endurance, immune health, and nutrient absorption.

Magnesium (from Magnesium Bisglycinate Chelate)

120 mg

Magnesium is a key mineral contributing to performance and overall health alike. However, certain forms of magnesium often used in sports supplements are poorly absorbed and may cause laxative effects. Transparent Labs ZMO contains Magnesium Bisglycinate, a non-laxative, highly bioavailable form of magnesium [1].

Compared to zinc, magnesium shows greater promise in positively affecting testosterone levels. A recent 2010 study found that sedentary and athletic males displayed increases in testosterone via magnesium supplementation. The greatest increase was in athletic individuals, as exercise also increases testosterone [2].

Aside from testosterone, magnesium supplementation is linked to greater insulin sensitivity, reduced blood pressure, and reduced stress/anxiety [3, 4, 5].

Zinc (from Zinc Picolinate)

11 mg

Compared to other zinc sources, zinc picolinate has long been established as one of the most bioavailable supplemental forms [6]. 

Most people understand that zinc is an essential mineral, but zinc in and of itself isn’t an unregulated testosterone booster; however, zinc deficiency will lead to suboptimal testosterone levels in men. This has been evaluated in many studies, one of which found that testosterone levels quickly normalized after restoring healthy zinc levels through supplementation [7]. 

Zinc is also one of the key minerals responsible for healthy thyroid function, and zinc deficiency negatively affects thyroid hormone production. This reduces basal metabolic rate (caloric burn) and protein utilization in the body [8].

Prolonged exhaustion exercise has been found to significantly reduce concentrations of both thyroid hormones and testosterone in athletes. Evidence suggests that this reduction can be prevented with long-term zinc supplementation, thus benefiting performance [9].

Oyster Meat Powder

500 mg

The flesh (meat) of oysters is regarded as a potent aphrodisiac due to its naturally high zinc and magnesium concentrations. In addition, oyster meat is rich in important trace minerals that act as co-enzymes in the body and maximize zinc and magnesium utilization. The micronutrient-dense nature of oyster meat has led to several studies investigating its implications for increasing endurance, antioxidant status, and immune function in athletes [10, 11, 12].

Noticeable difference in sleep and productivity

I've had trouble sleeping for more than 2-3 hours without waking up since University, i've tried an array of supplements, natural products, CBD, THC etc with not much improvement.

This is hands down the best product i've used to help me A) get to sleep B) stay asleep and C) wake up feeling refreshed and energized. Going into 3 weeks now testing this product, can't see myself trying anything else at this rate.

WOW! HIGLY RECOMMEND!

As someone who spent the last 10 years, not sleeping well as a result of my time in the service, I decided to try this supplement and was very impressed with how deep of sleep I was able to get into consistently taking it. I started with the two capsules per night, and was very satisfied. On nights after I’ve had a very stressful day at work, I will take three capsules before bed and get even better sleep. Every time I close my eyes, I go into a very deep rem sleep, and have the most vivid dreams.

Not sure this supp is a must

First time user- taking for a week now. Seems like a mixed bag of results. Personally, I wake up once a few hours after going to sleep and my dreams are very vivid, and usually chaotic. I normally don't recall my dreams not on this supp. On ZMO it seems like the intensity of my dreams interrupts my quality of sleep. I'm able to go back to sleep quickly but it seems counterproductive to the purpose. Health/recovery wise I don't notice much change. I will try for another week and cycle off before reporting with another review!

Consistently Waking Up

I’ve cycled on and off this product hoping for better results each time. When I’m off this product I sleep like a baby through the night (hardly ever wake up). But I when I take ZMO, I’m guaranteed to wake up once a night (like wide awake) and stay awake for at least 20-30 mins before falling back asleep. I love TPLs other products - just haven’t had success with this one.

More Sleep = More Strength

I paired this with Ashwaganda by Transparent labs. I train on5 days week CrossFit and 2-3 hr training . I went from waking up 3-4 times night to maybe 1 or none . And I made sure I cut caffeine out earlier in day and I am performing better my VO2 max on Garmin has went up past 8 months and lifts are easier. This 💯 made a difference and my review is 💯 real and unpaid. I did my research before trying three things and it has helped greatly

Restless sleep

I took these for 2 weeks thinking the longer I wad on them the better it would get. I consistently was restless and could not sleep more than a few hours at a time. Very disappointed, since every product I have purchased before has been 5 stars.

Really works!

I purchased this for myself and my wife. She has constant RLS and cramping in her calves. I read others reviews on this product so I wanted to give it a try.
Within a week of taking this, my wife has not had RLS or cramping in her calves. This has helped her tremendously! It also helps with my recovery and better sleep.
I've been a long time customer of Transparent Labs. I do not use any other products on the market, other than TL. Keep up the great work and products!
