  Helps with depression and sleeping...no side effects

  I have seasonal depression. Every winter by January and February I have a really hard time functioning without getting emotional and feeling very overwhelmed. I live in New England so sunlight is limited then. I use a happy lamp, eat organic, greatly limit junk, and I'm wheat and soy free. So I've done my due diligence, but it has never seemed to be enough. I also typically have a tougher time than usual sleeping at night. This winter I took 5htp for the winter and I cannot say enough how instrumental it was in helping me feel normal, happy, and productive for the entire winter. I also slept so much better this winter which means I'm not coming into the spring season on a deficit. This is fantastic because I'm usually playing catchup by the spring and it takes me until the beginning of the summer before I'm even feeling good again. No side effects whatsoever, easy to take.This is an amino acid tryptophan and a precursor to serotonin (which is made in the gut) and melatonin. If your gut is off balanced or you're missing something that would allow your body to produce what it needs, your brain simply cannot get enough serotonin, the feel good hormone. I have recommended this to several people who have also experienced great success with it and will continue to do so.

  I got to there because I was feeling so bad that I actually typed into Google

  Hey everyone, I've been using 5-HTP along with L-Tyrosine for six weeks. These products are a life changer for me! I read about this amino acid, (L-Tyrosine) in an article at psychologytoday.com. I got to there because I was feeling so bad that I actually typed into Google; " How can I stop feeling so bad", which, since the inception of the internet, I have done many times. It was actually a casual mention of L-Tyrosine. Then I came straight here to Dropy to see if I could get it and bingo, it was available and there, in these very helpful reviews was a gold mine of help, about 90% positive, while alone made my day and filled me with hope.I should stop and mention that at this time not only was I feeling terrible, I wasn't sleeping well, tossing and turning all night and full of anxiety during the day. I am a graphic designer/internet marketer who works at home and I could barely even motivate myself to get anything done. I was actually in a panic. I was experiencing the worst anxiety/depression of my life and from past experience didn't want to see a doctor.I have been through that route when I was younger, about 30 years ago, (I am in my mid 50's), and though it was nice to have someone to talk to, the meds did little and the side effects were unpleasant. I should also say here that I am becoming an advocate for depression/anxiety, for me this is a chemical thing. Yes, I have problems, but nothing in my life experience could make me feel this bad. People have to understand the types of depression.I researched as much as I could about L-Tyrosine and found out a lot of useful info. I went to seminar at me kid's high school and learned about the links between, serotonin, dopamine and depression. That a lack of serotonin can depress and cripple you, even cause outright fear. Anyway, I want to write a blog post, heck a book about this subject. I ended up using a "stack" which is 500mg tab of L-Tyrosine in the morning with water on an empty stomach and I also take a 50mg tab of 5-HTP at dinner with food. These are amino acid supplements, totally natural and with no side effects, and you know, a much lower price than the SSI drugs the doctors, I will keep that opinion to myself, can prescribe.I am feeling great and , honestly more productive than ever! I am sleeping much better, not perfect but getting my rest. I am going to venture to say that if I tried this method 30 years ago, my life would be much different overall!Do some research and check it out, This is what living is all about, being happy and engaged.

  Helps to "even things out"

  I had never heard of 5-HTP before reading this bookThe Mood Cure: The 4-Step Program to Take Charge of Your Emotions--Todayon my Kindle. According to the book 5-HTP or 5-hydroxy-tryptophan (5-HTP)is a compound created in the body which is used to regulate serotonin levels in brain and central nervous system. A supplement of 5-HTP is said to regulate moods, help treat anxiety and some sources say it could possibly aid in weight loss. (I haven't been able to confirm any of the weight loss claims - I'm just as hungry as ever.) It's also said that 5-HTP helps with insomnia. What I found was that it does act quickly (like within half an hour or less) to even out some feelings of anxiety and at night it makes it easier to fall asleep. The effects are subtle, but they are definitely there. If I take more than one they're a little more evident.After I first read the book I went to the drugstore where the capsules available were 100, 200 and 300 mg. each. I wanted to start out with this 50 mg. dose that was suggested in the book. I found that if I take 300 mg or more over the course of a day it can sometimes backfire and I have a harder time falling asleep. I'm not sure why that is. I also sometimes get a little ringing in my ears if I take more than 50 mg. at a time and the higher doses can produce very vivid dreams at night, sometimes a little too much so, where I feel like I'm not sleeping that well. (It could actually be the opposite.) So I find that taking capsule in the morning if I feel anxious and one before bed usually works well for me and I can definitely tell the difference in my mood throughout the day. I feel more positive and less worried. (I'm a professional worrier!)I like that this formula is only 50 mg. so I can regulate the dosage easily without taking too much. So far it has been helpful. I gave it 4 stars instead of 5 because I don't really know long term how it will work for me. It's been less than a month that I've been taking it. I'll come back to update this review after a couple months.

  Makes me sleepy but works well

  It makes me feel good and relaxed but the downside I have to it is that it makes me feel sleepy at times
