ZMA is rated 4.6 out of 5 by 41.
Rated 3 out of 5 by from TOO SOON TO TELL I have been taking this at bedtime and I am hopeful.

Rated 5 out of 5 by from 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.

Rated 5 out of 5 by from Awesome I've been using this for years! Helps with sleep. Helps with recovery after work out. Swansons is a great value!

Rated 5 out of 5 by from 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

Rated 5 out of 5 by from 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.

Rated 3 out of 5 by from 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.

Rated 5 out of 5 by from 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.

Rated 4 out of 5 by from ZMA I feel it increased my toning during exercise and increase the testosterone level for more energy.

Rated 5 out of 5 by from Good Purchase It helped me to go to sleep.Very good for recovery after workout. Best product ever used

Rated 4 out of 5 by from 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.
Date published: 2013-06-12
Rated 5 out of 5 by from 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.

Rated 4 out of 5 by from 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.

Rated 5 out of 5 by from 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!

Rated 5 out of 5 by from 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.
