Optimum NutritionMuscle Recovery and Endurance Supplement for Men and Women, Zinc and Magnesium Supplement, 180 Count

Optimum Nutrition's Zinc Magnesium Aspartate capsules have been a welcome addition to my daily routine. As someone who leads an active lifestyle, I was looking for a natural way to support my recovery after workouts and improve my sleep quality. These capsules have proven effective in both areas. I've noticed that I feel less fatigued and more ready for my next workout, thanks to reduced muscle soreness and faster recovery times. Moreover, they have helped me achieve deeper and more restful sleep, which has improved my overall well-being. The capsules are easy to take and have not caused any digestive issues. If you're looking for a natural supplement to support your fitness journey and enhance sleep quality, I would definitely recommend trying these capsules.

I love these pills!I have been taking these for at least 3-6 months now. And I find that I have a BETTER quality sleep with these. I wouldn't say that they make me feel sleepy whatsoever... I have to do things earlier in the day and change my diet to want to fall asleep sooner. But I find that I feel more refreshed with these.I don't feel like I am missing out on something.When I don't take these, I feel like I had the worst night's sleep even if I did get 8 hours.I am an athlete that plays sports about 2-3x a week (pickleball, volleyball and softball). And then I also work out 5x a week.I will tell you that the SIZE of these pills are a bit bigger... so prepare to swallow. These are capsules. So I would NOT recommend cutting into these pills as the ZMA formula will spill out and you will not get the right dosage.

As Described, Great Product & Great Value

Optimum Nutrition is the best supplement provider on the market. In the health industry companies and brands come and go like the seasons, but ON always remains. They make great, affordable, supplements that work and don't add any junk or fillers. This company is best known for their whey isolate and it really is the gold standard for weight lifters and competitors. They also make a very good ZMA, Amino Energy and Creatine supplements. I know that when I buy ON products I'm getting a quality product that won't taste like garbage. If you've tried more than one protein powder, then you know what I'm talking about!I'm going to give it to you straight, this stuff will not increase your sex drive or help you sleep more soundly. I've been using ZMA since 2008 on a 3-1 cycle and I have never noticed a difference between on and off months. What it does do is help you recover while you're sleeping. When I take ZMA I feel less drained and less sore than when I don't take it. There is more than one study out there that links ZMA, Tribulus, and other test boosters to placebos. It may be possible that it helps you maintain a normal hormone level, but it won't increase hormone level production.

I've been taking these for over a month and my sleep is better and I'm not sluggish during the day.

I have been taking for 4 years and will never not take it. My sleep is amazing and no achey muscles in the morning. I life heavy so this supplement at night is perfect for me. Im 140lbs and two capsules give me creepy vivid dreams. One capsule is perfect.

Great product! it does aid in recovery. The only thing for me did not help to take before bed. For some reason it gave me energy but making me feel relaxed so I take during midday.

Horrible sleep! I took three pills as suggested and was awake all night. The only thing that was vivid for me was staring at my pillow at 4 am - I took the pills at 10 pm. I get much better results with ashwaganda and will be returning this and sticking with something that actually puts me to sleep.First Update:I decided I’m going to keep going with ZMA. Not because it is great, but because I want to give it a fair shot. Maybe it takes some people longer to glean benefit from this product.I’m going to start my review at 3 stars instead of the one star originally. You’ll notice it’s already at a two. That is because on the second night I dropped my dose down to one pill. The idea was to see if three pills where too much and maybe I don’t need that much Zma in my diet. No, that did not help. I took one pill and fell asleep quickly at 10pm. However I was wide awake at 2:30am and could not fall back asleep until 4:45am. I had to be up at 7am. Additionally, every time I take zma I am very groggy the next day. I still think ashwaganda is a better product with similar claims. However I’m going to do 2 pills tonight and follow that for a week before adjusting the star rating again.Just as an aside, I have read several studies on google scholar about zma and there has yet to be a positive correlation between zma and an increase/ decrease in anabolic or catabolic hormones.Second Update:Two pills: I took two and I felt like I was going to be wake all night again. I took them at 8pm and at 11 pm I was wide awake. However, a wave of relaxation came over me and I went right to sleep. I also slept straight through the night. The next morning I wasn’t groggy but I wasn’t full of energy either.I have increased the rating to three stars because I have taken the two pills a few nights and have slept through the night. It hasn’t been great sleep, I still feel tired in the mornings but it hasn’t kept me up either. I will finish this bottle but will not be buying any more after this.
