Helps Ease Anxiety and OCD Thoughts and Rituals
I have taken this brand of 5-HTP for years and it has greatly improved my quality of life. It cured my insomnia and I am now able to sleep through the night. It has helped immensely in lessening my depression. It also helps ease anxiety as well as OCD (Obsessive-Compulsive Disorder) thoughts and rituals. In some ways, it works immediately - The first time that I took the 5-HTP, in about 30 minutes, I felt euphoric - happy, relaxed, and sleepy. I slept through the night, and still do. It was a relief to know that it worked that fast. It takes maybe three to four weeks to notice more permanent changes in mood, like an all-day improvement in depression, instead of the immediate effect that it has after you take it because it is leveling out the seratonin/melatonin levels in the brain. It has been compared to traditional anti-depressants, with relatively no side effects. For a week or two you may have intense and vivid dreams. I also had increased headaches for the first week or two, but after that it significantly reduced my migraines. The recommended time to take 5-HTP is about half an hour to an hour before bedtime. I used to take only 100 mg a day, but have started taking the 200 mg capsules. I don't really notice a huge difference between the two, except that maybe my body tolerates the lower dose better. Sometimes the 200 mg capsule feels like too much and I get tense if I don't get to sleep right away. I fully recommend this product because it really has done wonders for me.

Really Helps
This one is pretty strong, maybe best to start off on 50mg and work your way up to this 200mg one because your body can build up a tolerance. I feel a sense of calm and "everything is going to be alright" which really helps with my anxiety. Be careful if you have a lot of things to do though because I find it makes me a bit indifferent to tasks. Remember if you have depression and anxiety, any kind of pill will be just a quick fix to help you feel emotionally OK in the short term, but if there are non-chemical reasons like trauma or bad relationships causing your illness you will need to deal with that in order to properly heal and feel deeply happy.
