ZMA may be a supplement but I take this one hour before bedtime and I have a good nights sleep. I don’t believe in sleeping aids but this product relaxes me so I can sleep.

After taking this for two days, I developed a weird metallic taste in my mouth that lasted a week. Nothing could get rid of it — not mouthwash, not brushing. I've used zinc lozenges before that never did this. Something about the form they use just didn't agree with me.

NutraBio ZMA: A Simple, Effective Recovery Boost
Verified purchase
NutraBio ZMA is a solid supplement for those looking to support recovery and sleep. The blend of zinc, magnesium, and vitamin B6 is well-dosed and easy to take with 2-3 capsules before bed. I noticed improved sleep quality and felt more rested after workouts, which helped with recovery. The 180-capsule bottle offers great value, and the product is non-GMO, gluten-free, and vegetarian-friendly. Overall, a reliable choice for anyone with an active lifestyle.

Perfect for recovery and sleep
Verified purchase
With this supplement my sleep has significantly improved, no waking up during the night. Composition is made by the magnesium type that helps relaxing and sleep. In terms of use, just make you don't take it with dairy products in the same meal or couple of hours. It acts better when taken on an empty stomach so 2-3 hours away from your last meal. I also take one in the morning after waking up as I usually skip breakfast until 10am. Size is easy and packaging is straightforward.
