Anabolic Mineral Support*
Regular price $14.00

Exercise and stress deplete the minerals your body needs to function and perform optimally. If you train hard, sweat, or experience stress, which describes almost everyone, chances are you're deficient in zinc and magnesium, leading to slow muscle and strength gains, poor recovery, decreased testosterone, and a host of health issues. This original ZMA® zinc/magnesium formula from SNAC replenishes these deficiencies, increasing natural anabolic hormones and improving athletic performance. One study shows ZMA® supplementation increases free testosterone by 30 percent.*

Do You Need More Zinc and Magnesium?

Zinc is vital in maintaining healthy immunity, metabolism, anabolic hormone production, and general wellness. And scientists consider magnesium the "master mineral" because it plays a role in over 300 biochemical reactions in the body, many of which are directly related to muscle function, insulin sensitivity, and protein synthesis.*

Unfortunately, zinc and magnesium deficiencies are widespread. In one study, researchers tested the mineral status of over 250 NFL players. Over 70 percent of the players were either depleted or deficient in zinc and magnesium. Even if you're not a competitive athlete, these same deficiencies can lead to decreased hormone levels and diminished strength and power.*

Eating the Right Foods

It's a challenge to get sufficient zinc and magnesium amounts in your diet. Once considered "mineral-rich" foods are now deficient because of modern farming methods. Even buying organic foods, you'd have to eat nine bananas to get the RDA of magnesium, let alone meet your increased athletic demands. Adding to the challenge, regular zinc and magnesium supplements are poorly absorbed and offer little help.

The Superior Zinc/Magnesium Formulation

University studies show that the zinc and magnesium contained in the ZMA® formula absorb far better than other forms.* Studies also show ZMA contains the exact ratio of minerals to increase anabolic hormone levels and strength in trained athletes.* The zinc and magnesium contained in ZMA are highly bioavailable and known to have superior absorption.* Vitamin B6 is included to enhance utilization.*

30 Percent Increase in Testosterone*

An independent ZMA study on NCAA football players shows that the group taking ZMA increased free and total testosterone levels by 30 percent in 8 weeks, while the placebo group showed a decrease of 10 percent.* In addition to increasing anabolic-hormone levels, the ZMA group gained 2.5 times more strength and functional power over the placebo group.*

Better Natural Sleep*

Magnesium and zinc deficiencies are both associated with poor sleep, and most ZMA users report better nights' rest when using ZMA.*

Works as expected

Works great, just wish there were more servings per bottle. Plenty of room in the bottle to add more servings without increasing its size and I hate to waste of plastic.

Very satisfied.

Great product

I’ve been using this for about a month now. I can see the benefits already. I recommend this product.

ZMA for flu recovery

Been using ZMA for over a decade. This review is to shower accolades on its ability to help recover faster from illness. Gave ZMA to a family member when they had a nasty flu and recovery seemed to accelerate. Only other aids were D3 and C, as well as your typical flu medicine...oh, and chicken soup of course.

Great magnesium source

This stuff works. Been using it 4 years.

It’s Works

Taking ZMA just helps me sleep better. Simple and easy. Thank you.

Magnesium used in over 300 enzymatic reactions throughout your body!

Did you ever have your eye spasm where it starts twitching and it never stops? Not painful just annoying. I found out that could be a symptom of magnesium insufficiency. Enter Biotest ZMA eye twitches are gone, I sleep better and it comes in a sexy blue bottle!

I like ZMA but...

While I enjoy your ZMA offering, some of your other products have become constrained because of "supply chain" or company decisions. I know it can be difficult to deliver what every customer wants. It would be helpful to me to have more options and look at cost-cutting in other areas.

This an excellent product. While using it, I have had a better sleep quality. I recommend it 100%.

Excellent service and exceptional product

Best quality is the standard of all Biotest's products.

My daily night time ritual

Gives me better sleep while taking ZMA.

Essential supplement

I don't ever want to be without ZMA as it helps promote good sleep and particularly when paired with Z12, which I wish was still available.

Just started using ZMA 3 months ago. What a difference on sleeping and recovery. Not kidding.
