ZMA Supplement & Benefits by Optimum Nutrition: A Review

The road to wellness is not something that can be achieved overnight. It requires countless hours in the gym, smart food choices, and an overall lifestyle shake-up. Add to that the fact that you also need to spend a minimum of eight hours per day for work or school, and you’ll feel like you’re in for the greatest challenge of your life.

For these reasons and more, fitness and nutrition experts from all over are continuously introducing newer and better dietary supplements that can aid the body in a number of ways such as in promoting muscle recovery, better sleep, weight loss, more strength, and increased endurance. One of the trusted brands that have been in this industry for years is Optimum Nutrition.

About Optimum Nutrition

For more than three decades, Optimum Nutrition has helped regular individuals and elite athletes from around the globe in achieving overall wellness through proper nutrition. Their experts are passionate about providing sports nutrition solutions that help promote energy, endurance, power, speed, and strength training.

Every one of their company-owned and -operated production facilities was specially designed to produce innovative and high-quality supplements that help bring out one’s real strength. Among their latest inventions is the ZMA Nighttime Muscle Recovery Aid Supplement.

ZMA Nighttime Muscle Recovery and Sleep Aid Supplement

With every capsule of ZMA, you can expect to get a compelling yet safe and well-researched dosage of zinc, magnesium and vitamin B6. This combination is recommended for those who aim to build muscle strength, as zinc and magnesium aspartate are believed to be the most effective mineral that can help support this.


What’s Inside Every Bottle

  • GMP-Certified Products

Even at the acquisition process of the raw ingredients used in making ZMA, Optimum Nutrition is focused on quality. Every vendor presents a Certificate Analysis of every raw supply. In addition, routine checks are also performed on all storage and production areas. That being said, you can be sure that, with ZMA, you are getting the best quality products that are worth the money.

  • 180 Capsules

Each bottle contains 180 capsules, where the recommended daily dosage is about two to three and should be taken on an empty stomach for better absorption. During the night, one capsule should be taken 30 minutes to an hour before bedtime so as to promote better quality sleep. All in all, one bottle should last for two months.

Key Ingredients

  • 450 mg of Magnesium (as aspartate)

Magnesium, when taken by the body in the form of aspartate, is believed to extend stage 3 and 4 slow-wave sleep, providing deeper and better quality sleep. As a result, magnesium will indirectly cause a boost in the growth hormone levels. A study has shown magnesium can make people groggy that is why it is recommended to take before bedtime.

  • 30 mg of Zinc (as aspartate and monomethionine)

Zinc is a powerful antioxidant that our system needs and craves for. It encourages the activation of an enzyme that is known to promote better immune system function and overall health. Zinc has been shown to increase testosterone levels. As such, zinc plays a role in the body’s recovery after strenuous body building exercise. Be extra mindful, though, because a high dosage of zinc may result in reduced levels of HDL, which is actually the good kind of cholesterol that our body requires.

  • 10.5 mg of Vitamin B6 (as pyridoxine HCI)

Vitamin B6, when combined with magnesium, promotes better and quicker absorption of these minerals. Consequently making ZMA become more effective in providing muscle recovery and better-quality sleep.

Best ZMA Supplement at a Glance

Optimum Nutrition is well-known in the fitness industry as among the leading manufacturers of quality dietary supplements. If you are looking to increase testosterone levels and a boost in your post-workout recovery, as well as better sleep, you can find help from this product.

Inside every bottle is 180 capsules packed with just the right levels of zinc, magnesium, and vitamin B6 to promote overall health, especially for fitness buffs and professional athletes. The ZMA Nighttime Muscle Recovery and Sleep Aid Supplement is recommended for both women and men’s health.

Every capsule is guaranteed to be of high-quality as they are produced in GMP-certified facilities in the United States. Moreover, daily routine checks of these facilities are also done to ensure safe production.

ZMA by Optimum Nutrition vs. Other Similar Dietary Supplements

One dietary supplement that has the same features and effects as the one we have presented above is the PrimaForce ZMA Supplement. Both of these products have the same levels of magnesium, zinc, and vitamin B6 in every easy-to-swallow capsule. Neither of these products include whey protein or amino acids.

PrimaForce prides itself on using ingredients that are pharmaceutical-grade and clinically-tested to be pure, safe, and potent. Like the ZMA Dietary Supplement by Optimum Nutrition, this one also claims to promote an increase in muscle building strength and performance, muscle healing after intense workouts, and healthy hormone production.

The Verdict

Taking everything into consideration, we would most certainly choose ZMA by Optimum Nutrition over any other product. This brand has been in the fitness and wellness industry for decades, which only goes to show that their products are of extraordinary quality.

The amount of zinc, vitamin B6, and magnesium in each Optimum Nutrition ZMA Dietary Supplement capsule also adheres to the recommended daily levels that are believed to promote overall wellness, especially for those who have trouble having a good night’s rest and those who need help in recovering from a strenuous workout session.

Similar to any other dietary supplement, though, this should be kept away from the reach of children as its zinc and magnesium levels are set explicitly for adults. Additionally, it is recommended to consult your primary care specialist first before taking ZMA Optimum Nutrition with your medications. That way, you can rest assured that you are not putting yourself at risk.
