For Anxiety "Don't take this with benzos, it made me extra drowsy and anxious. One pill-I only took half of one pill (50 mg!). I got some kind of adverse reaction. My insomnia got worse, I got panic attacks, shivering, tremor, felt disoriented, and seriously more depressed. Now I have woken up in the middle of the night for many nights to the same feeling: anxious, can't fall asleep again. I regret taking this. And I said once again: DON'T MIX THIS WITH BENZOS and be careful if your nervous system is sensitive, you are sensitive to supplements, or you suffer from bad insomnia, because it can cause a paradoxical reaction. Start with tiny doses to find out whether this is the right supplement for you. For me, it definitely is NOT. This supplement also has many side effects."

For Anxiety "I’m a 51 yo female with a long history of anxiety and depression. With menopause just around the corner, there are days my anxiety is off the charts. About 6 months ago, I started taking 100 mg daily. I was also having moderate to severe panic, heart palpitations, sweating, and severe vomiting. I didn’t make the connection to 5-HTP until I recently started taking it again. This time only 25 mg. Same symptoms but milder. I cannot be 100% sure, but I’m making the connection to this supplement. If you’re thinking of taking this supplement, I highly recommend talking to a holistic health practitioner first. Not to be dramatic, but my episodes landed me in the ED three times last year. It was quite scary."

For Anxiety "Took 5-HTP 100 mg at night with magnesium, to calm my mild anxiety and sadness, help with sleep. I was post-concussion and being treated for autoimmune disease. At around 6 months, I increasingly noticed I was waking at night, I started getting more anxious, suicidal thoughts. During this time, I also did a small intestinal bacterial overgrowth (SIBO) treatment of antibiotics, which probably helped my gut work better, and then started low-dose naltrexone for my autoimmune disease. I started to have heart palpitations, sweating at night, depressed thoughts, panic attacks which I never had before, where you get arrhythmia, continuous bad thoughts, tingling in your fingers, and feel dizzy. When withdrawing from 5-HTP, I had a horrible time. I had to withdraw slowly, as I had a lot of the symptoms of SSRI withdrawal. My brain and thoughts were so disturbing. I would be very cautious using this drug long-term and continuously. Study needs to be done on low-dose naltrexone and 5-HTP. Or post-concussion and 5-HTP."

For Insomnia "Started taking 5-HTP with magnesium. Had to get online as it's not an approved drug in Australia. After 2 bottles, I had to come off it as it was upsetting my bowel. I started having panic attacks, depression, insomnia. This withdrawal lasted 4 weeks. There should be a warning about coming off this med, be careful. Maybe this is why it's not approved here."

For Anxiety "I've been struggling with anxiety and panic disorder for 3 years now and finally built the courage to try a supplement. This is my 3rd day on Natrol's Daily Stress Relief. It has 5-HTP, magnesium, B6, and 12, and some other vitamins. 100 mg after breakfast. Every day it's been different. My first day was amazing. I felt the physical symptoms I was anxious, but I didn't fear the sensation. I hope that even makes sense. I was in tears because I haven't felt not being scared in 3 years. My 2nd day was horrible... terrible anxiety symptoms, constant palpitations, panic attack, and a meltdown. Today is my 3rd day, I felt so off today... anxious, irritable, like nothing satisfied me (I'm usually a happy, upbeat person despite the anxiety). I was thinking about not taking it anymore because it feels like I'm getting more negatives than positives, but I read a few comments about taking a lower dose. So tomorrow I'm going to try splitting the pill in half and take 50 mg. I hope it makes me feel better."

For Anxiety "BE CAREFUL! I took 5-HTP without any advice from the doctor, and it kickstarted my panic attacks journey. Of course, I had some trauma deeply rooted in my subconscious, that was the primary reason for my panic attacks, but 5-HTP unleashed all of it! I ended up having to go to a psychiatrist and went on SSRIs to fix myself. The doctor told me the dosage advised on the 5-HTP box (100-200 mg/day) was way too high for me and that messed up my brain. Just don’t take this without a doctor’s advice, please, it might do more harm!"
