Works for me!
This formula really helps muscle recovery and sleep. Tried many many brands and formulas. This is a winner for me and my body.

High quality magnesium
This magnesium is awesome. I do recommend taking before bed because it puts me in a state of relaxation. Highly recommend.

Great product!
Received the Magnesium Capsules quick from Amazon! I just started taking them about a week ago and can already notice the positive changes I feel after taking them. Great product!

Best Option
I have been taking this for quite some time. It definitely helps with sleep. I think it also makes me have less brain fog when I wake up but that might be a side product of better sleep. Its definitely better for the cognitive function. Everything else is harder to detect. It is worth the money for me.EDIT* I also get leg cramps when I forget to take mine at night – definite sign of magnesium deficiency. It does the job with no side effects.
Amazon Customer –
Multiple types of magnesium
I really haven’t been taking this long enough to see any real difference. The pills are easy to take and they do not give me any intestinal distress. I think they are on the expensive side but it’s hard to tell whether they’re effective yet. Three types of magnesium are included in this formula. I don’t notice any difference in my sleeping. I need to give it a few more months before I can give an objective review.

How do I know?
Satisfied with product as presented. But how do I know whether magnesium is work? Trust. Yes, I trust Peak Performance; although, I received recall notice for Zinc and did not get reply from claim submitted by email as instructed. Peak Performance is supplied by third-party manufactures, so they are simply a distribution company who markets.

Multiple Forms of Magnesium, Easy to Swallow
My doctor has prescribed for me to take 400 mg of magnesium daily, so I’ve tried a lot of magnesium supplements. I like that this brand contains three forms of magnesium in one, andI like that it contains 500 mg of magnesium in one (a little large) capsule, so I can get the 400 mg I’m supposed to take with just one pill. Because it’s a capsule rather than a pill it’s a lot easier to swallow. I previously took a single large magnesium pill and I had to cut it in half in order to take it comfortably, which isn’t necessary with this capsule – it goes down a lot easier and isn’t so big that it’s uncomfortable. I highly recommend you try it if you want/need a magnesium supplement!

Best sleep I’ve had in a long time.
I had a very difficult time falling asleep at night until I started taking this magnesium. I like to take it about a 1/2 hour or so before going to bed; it gives it time to kick in. This magnesium helps me fall asleep and stay asleep. I definitely recommend it. I am not paid for my review.
