A Wonderful Supplement for Sleep

Posted by Reviewer2588465 on Mar 28, 2013

I've found that Tryptophan and Magnesium are what I've needed for a good nights sleep. I stopped waking up several times a night when I started taking these. I don't know if I'll ever stop waking up in the middle of the night completely, but these sure have helped. Try this free sample and give it a shot.

My favourite product

Posted by Reviewer2813819 on Nov 21, 2012

A doctor told me almost 40 years ago that I was low on Tryptophan. 10 years ago I began having severe panic/anxiety, and was prescribed anti-depressants and sedative. Sure, they "help", but they don't cure anything, and I have to keep taking them because they do nothing to produce more tryptophan/serotonin in my system. Tryptophan containing foods do not contain enough tryptophan that my body needs. I tend to crave those foods and eat them all the time. Taking this I notice an immediate improvement in my well being, which I suppose is the real reason the EU has now banned this, along with other natural products in Sweden. They won't admit the reason, but I think they want everyone to be on drugs, or to buy their so called vitamins from their stores that do not contain enough vitamins to actually be very effective. Sad. After 10 years of seeking and trying to take responsibility for my own health I find something that works and now I can no longer order it. Hopefully, other countries will not try to do the same.

Tryptophan is a precursor to serotonin, a hormone contributing to the feelings of well-being, and people with low levels of serotonin are prone to depression. A study reported in the November 1982, "Psychological Medicine," investigated whether tryptophan could act as an antidepressant. The study involved 150 patients and lasted 12 weeks. It was found that tryptophan significantly improved depression and was not associated with side effects.
