Great for restless legs and kids who can't settle Review by

This product has never let me down. It fixes restless legs a treat, and aids with getting to sleep. Tastes great in a glass of water.
Thanks goodhealth.

Very effective magnesium in powder form Review by

I tried this for six weeks and ran out. I noticed that my sleep wasn't as sound, my muscle tension and headaches returned, and I wasn't as relaxed. I do believe the Good Health magnesium powder was working. I'm now back on it and find that I have a good nights sleep, and it improves general wellbeing. I've also found it effective for stress and sore muscles. I'm a fairly active woman with a moderately stressful job, so magnesium is essential for me. This powder works and has a pleasant citrus taste at a very good price thanks to Health Post (love your service!). I've tried far more expensive magnesium powders, which tasted sickly sweet or didn't seem to work as effective as this powder. I would definitely recommend it.

This is a wonderful supplement for ... Review by

This is a wonderful supplement for energy, and to help relax the muscles. I especially found it helpful for the tension I have in my neck and the feeling of depression.Pleasant tasting, especially when used in fruit smoothies.
