Customer Ratings & Reviews

Rated 4.6 out of 5 by 41 reviewers.
Rated 3 out of 5 by TOO SOON TO TELL I have been taking this at bedtime and I am hopeful. March 20, 2016
Rated 5 out of 5 by Good night time recovery supplement I have not been taking the amount recommended, instead I just take one capsule each night before bed. I work a physically demanding job and I am middle aged, so I do believe this helps keep me going. As others have mentioned, it does seem to effect dreaming. I take a few days off from this product every month and I can tell either way when it comes to sleep patterns. March 19, 2016
Rated 5 out of 5 by Awesome I've been using this for years! Helps with sleep. Helps with recovery after work out. Swansons is a great value! December 16, 2015
Rated 5 out of 5 by excellent Swanson has the best price on ZMA, and they are a brand I can trust. ZMA always helps get me to sleep, and feeling refreshed and strong the next day. I do not take everyday, but when I am having trouble getting to sleep or need extra energy the next day it helps me ou September 24, 2015
Rated 5 out of 5 by Great for workout warriors I bought this product to help with workout recovery and it does just that. With that being said, it will not restore you completely from an overly extended workout. But it will assist significantly in the recovery period. If you are modest with your exercise from one workout to the next it will help your recovery along with proper sleep, diet, etc. It resolves some of the depletion that occurs in the 48 hours after exercise and allows me to maintain my regiment. June 17, 2015
Rated 5 out of 5 by Great product. Great price. I take this before going to bed after working out at the gym. I sleep like a baby with ZMA. Highly recommend! May 26, 2014
Rated 3 out of 5 by Magnesium citrate better? I use magnesium -- usually citrate -- to help me sleep better. I think that worked better for me than this one (magnesium asperate). May have dreampt more, but sleep seemed more fitful. Also, seems I needed 4 caps, rather than the recommended 3. April 1, 2014
Rated 5 out of 5 by It Works I'm a 60 yr-old male and hit the gym 3x/wk (20 minute cardio + 20 minute weights). I take a couple of these before bed and my 5-6 hour sleep feels like 8 . . . but it may cause you to have vivid dreams, which can be bothersome. I also notice a boost in strength and energy when using this supplement. Remember: Every body works and reacts differently when it comes to supplements. December 25, 2013
Rated 5 out of 5 by Zma I was eager to try this stuff because Ive read a lot about it,one thing I have noticed right away was the dreams every night.Which told me I was getting some deeper sleep,very happy with all the swanson supplements and were super fast for delivery. November 29, 2013
Rated 4 out of 5 by ZMA I feel it increased my toning during exercise and increase the testosterone level for more energy. August 4, 2013
Rated 5 out of 5 by Good Purchase It helped me to go to sleep.Very good for recovery after workout. Best product ever used July 8, 2013
Rated 4 out of 5 by Taking this with at least 2 to 3 grams (1/2 tsp) of L-Glutamine 1/2 hr before bedtime seems to work better for me rather than taking ZMA alone. June 12, 2013
Rated 5 out of 5 by Great purchase I had heard so much about this product and decided to try it. I have noticed good results, especially since I work out at the gym and taking this supplement has added an edge to my workouts and the appearance of my body. It is a great addition to my supplementation. May 31, 2013
Rated 4 out of 5 by ZMA Zinc, Magnesium and B-6 for better sleep I work a lot and ZMA was recommended to me to get a good nights rest. The one time I took two before bed I had a slight headache when I awoke. I don't usually have headaches so I presumed it was from this. I will try it again though since I bought two bottles. May 16, 2013
Rated 4 out of 5 by dont notice much on the workout end, but really helps with sleep. May 12, 2013
Rated 5 out of 5 by For me, improves sleep Started as part of workout on recommendation of Personal Trainer, but found it really effective at improving deep sleep. April 29, 2013
Rated 5 out of 5 by Important for men Supports Testosterone production. Good quality product. March 19, 2013
Rated 5 out of 5 by GREAT QUALITY I use this with testofen and see a big difference when working out and deeper sleep. March 14, 2013
Rated 5 out of 5 by Love this! I take this nightly as part of my bedtime regiment. :) March 13, 2013
Rated 5 out of 5 by ZMA I use this primarily to help with the recovery after working out. It not only helps me sleep better, but really seems to help absorb a lot of the achyness I get after lifting! February 27, 2013
Rated 5 out of 5 by Male Formula I bought this product for my son-in-law, because Zinc is involved in many metabolic reactions. He works very hard and since athletes have been reported to have lower levels of zinc and magnesium possibly due to increased sweating or inadequate intake in diet, I thought it may be the same with him, and it seems to be helping. February 23, 2013
Rated 5 out of 5 by I like this product... I take 3 at night to help me sleep. I can tell a difference the next day. I will continue to buy this product in the future. December 19, 2012
Rated 4 out of 5 by 4 out of 5 stars i'm a 60 year old male who rarely slept well. it seemed i could sleep once every 3 or 4 days out of exhaustion while the other nights consisted of a series of cat naps. 3 zma caps with 1 10mg melatonin 30min befor bed helps to achieve 5-7 hours of rem sleep. my pattern has reversed- 3-4 nights of good sleep. 1-2 nights a week not so much. it's still a big improvement. the older i get i realize what a great gift a good nights sleep can be. October 15, 2012
Rated 1 out of 5 by no differance I took this every night per directions and did not feel any different. It gave me no gains in strength or weight. October 11, 2012
Rated 5 out of 5 by What a great night sleep... This is not a sleeping aid... it provides you with mental clarity when you wake up. You feel great when you take ZMA. I can even get up in the middle of the night and go back to sleep real easy. I don't feel dopy or drowsy. You feel wonderful. I so recommend ZMA. August 24, 2012
