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
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
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
ZMA I feel it increased my toning during exercise and increase the testosterone level for more energy. August 4, 2013
Good Purchase It helped me to go to sleep.Very good for recovery after workout. Best product ever used July 8, 2013
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
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
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
dont notice much on the workout end, but really helps with sleep. May 12, 2013
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
Important for men Supports Testosterone production. Good quality product. March 19, 2013
GREAT QUALITY I use this with testofen and see a big difference when working out and deeper sleep. March 14, 2013
Love this! I take this nightly as part of my bedtime regiment. :) March 13, 2013
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
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
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
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
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
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
Works This product really works. I have used it now for about three months, and get some of the best sleep I have ever had. I have even taken it with dairy before bed. I am usually asleep within the first 30 minutes. April 8, 2012
Good product - best price ZMA is a relatively effective product and mostly does what it promises. It helps me sleep more soundly and seems to boost my production at the gym a little bit. As always swanson has the best price anywhere, so if you want to try it, buy it here. April 2, 2012
Cheap and effective. Most of the ZMA products claim to help you sleep...the only reason they claim that is because of the B6 and magnesium. In truth, it does help you sleep. I am a very active person and this product is perfect. I work out regularly and chronic weight lifting depletes your body of the minerals zinc and magnesium. This is a great value for a 30-day supply. March 18, 2012
great product So thankful my husband suggested I take this. I feel like I sleep great! Very happy with the quick shipping and friendly customer service. March 14, 2012
Excellent quality + competitive price = Great value October 16, 2011
great supplement great supplement, but current product not available. April 29, 2010
