I bought this because of the reviews. And it works!! Review by

What a wonderful supplement to assist sleep. I have tried other magnesiums, and other sleep supplements - but this one truly works. I am now recommending to friends.
Thank you Health Post. I appreciate the chance to read other's recommendations. And just the best service - always prompt delivery, no delays, very good prices.

I get restless legs most nights. As soon as I take this magnesium within 30 minutes or so they have gone. I also feel it helps if I wake during the night to help me get back to sleep. I highly recommend this product

I have tried Go Healthy Magnesium and it is a dismal product compared to Good Health Magnesium Ultra. I take 2 tablets about an hour before bed and i sleep right thru the night; i have been taking this brand for 3 months now and have also got my husband onto it who used to only have 4 to 5 hours sleep; he is now up to 7 to 8 hours per night. I highly recommend this product.

Works very well in easing symptoms of carpal tunnel syndrome, in conjunction with Good Health Turmeric 15800.

Love this stuff Review by
  • star

Have always struggled with getting to sleep, mostly trying to get my brain to shut down. I didn't want to take prescription medications. Someone told me about this Magesium Ultra and decided to try it. Wow, I was truly amazed. I take this every night about an hour before bed and have no problem getting to sleep and staying asleep. I will continue to take this every night. Great product!

I really noticed a difference, for once Review by
  • star

When I took magnesium in the past I wasn't noticing any change. By it's different with this product, I reallise I sleep far better (deeper, don't wake up in the middle of the night) when I take a pill before going to bed.
Only negative point: the pill is too big for me, I break it before taking it, but it seems as efficient since I really see a change when I take one.

excellent product Review by

I researched the best forms of magnesium to take, and this has good quantities of them. I think it has helped with my muscle cramps, though other things I take could also be helping. I would recommend this as one of the best products for magnesium, which is something probably most people need in NZ.

Excellent quality Review by

This product is easy to digest and relaxes muscles helping me to sleep. It is a quality product which I will continue to use.

Good help for sleep Review by

If I missed a dose in the evening, it will be difficult for me to get into sleep and I will keep waking up in the whole the night.
