Reviews

Zma

"A staple to have in your stack. The standard snac zma formula without stomach issues and one of the few to offer a 60 serving container of this."

— R (5/5)

Yes to ZMA

"Started taking this about 2 months ago. Didn’t “feel” any changes at first but as I’ve continued to take it, sleep it better and I’m getting good QUALITY sleep. Dreams are vivid and it’s amazing! If you try it, take it at least 2 months before you decide."

— Rachael G. (5/5)

It works

"Have used NB ZMA for a few years. A few months ago I made the mistake of purchasing another brand thinking all ZMA was the same. NOPE, the other brand gave me some serious stomach issues! So I’m back to NB and will only purchase from you as long as I’m using ZMA."

Q&A

Frequently Asked Questions

What is ZMA and how does it work?

ZMA® is a patented blend of zinc, magnesium (as magnesium aspartate), and vitamin B6 designed to replenish minerals lost during training, support muscle recovery and strength, and promote deeper, more restful sleep. NutraBio uses authentic ZMA® licensed from SNAC System, Inc.

What are the main benefits of NutraBio ZMA?

NutraBio ZMA® supports improved sleep quality, faster muscle recovery, and overall performance. It helps combat zinc and magnesium deficiencies common in athletes, is laboratory tested for purity and potency, and uses the original patented ZMA® formula.

Who should consider taking ZMA?

Athletes and active individuals who train hard, experience restless sleep, or want support for recovery and strength may benefit from ZMA®. It’s also useful for people at risk of low zinc or magnesium due to intense exercise or stress.

How and when should I take ZMA?

Typical ZMA® intake is 20–30 mg zinc, 400–450 mg magnesium, and 10 mg vitamin B6 taken 30–60 minutes before bed. Follow your product label for serving size. For best absorption, take on an empty stomach and avoid taking alongside calcium-rich foods.

Can ZMA help with sleep?

Yes. ZMA® was developed to enhance sleep efficiency, which is critical for recovery, strength, and muscle growth. Users commonly report deeper, more restful sleep that supports next-day performance.

Does ZMA increase testosterone?

Research in trained athletes has shown ZMA® may support increases in free and total testosterone within the context of an intense training program. Individual results vary, and more research is needed. Always pair supplementation with proper training, nutrition, and sleep.

Is ZMA safe to stack with other supplements?

Yes. ZMA® stacks well with protein, creatine, EAAs/BCAAs, and most recovery formulas. To maximize mineral absorption, take ZMA® separately from calcium-heavy products (e.g., dairy or calcium supplements). If you use sleep aids, consult your healthcare provider.
