Every year caught me in November that winter depression. I'll come in the morning hard out of bed quickly feel exhausted and hanging gloomy thoughts. That bothers me right, especially as I always has to deliver full power at work. My GP could not help further and gave me "recommended plenty of exercise in the fresh air. I have tried it already with St. John's wort and daylight lamps, but nothing helped. Then I a friend told that she removes her feeling low with L-Tryptophan has. So I've also given the product a chance. After just one week of taking I noticed actually a significant improvement. My momentum returned, the black thoughts broke up and I felt finally comfortable in my own skin. It seems that I had really under a serotonin deficiency suffered, which was eliminated by L-tryptophan. I'll take the capsules until the spring on and can only recommend everyone to try it even once.
