  • What buyers say about NOW Supplements, 5-HTP (5-hydroxytryptophan) 100 mg, Neurotransmitter Support

    When I took melatonin at night to improve the quality of sleep, it was better absorbed into my body than if I took it without it, and I would recommend taking 60 if you want to improve your sleep quality.

    I used to have severe anxiety and this product combined with Gaba and L-thenine saved my life and I never thought I would be able to live a normal life again.

    I purchased these two supplements on my own, and I am very satisfied with the results, because they were purchased at a much cheaper price.

    I get this feeling of "Woah, this feels good" every once in a while, but it helps me be more mentally sharp and less depressed, when I take this supplement with xa0, and it's combined with a 5-HTP supplement.

    I took these for a couple of weeks and noticed a huge change in my mental health, so I went out and got a second job on the weekends, which helped with my mental health.

    Common Questions


    Is there any additional vitamins or minerals blended with the 5-HTP?


    Both Dr. Pricilla Slagle and Dr. David Gersten say to take enteric coated p-5'-p with aminos.


    Can anyone tell me how this compares to vitamin world's 5-htp?


    In her book, The Way Up From Down, Dr. Slagel recommends Now Foods brand 5-HTP and L-Tyrosine for mood disorders.


    What is the difference between 120 and 2 120 bottles?


    I usually take 2 each night before bed, but the supplement comes in different strengths.


    Is it a time-released formula?


    I was told to take 50mg the first night at bed and if you don't fall asleep in 1/2 hour, then the next night take 100mg.


    A friend recommended 5-HTP, but I should only buy it if it's stamped "GMP" because it means it's been independently verified.


    After taking for 2 weeks, 4 capsule per day 2am, 1 lunch and 1 pm, I did not experience any change. However, when I tried True Calm (GMP certified) I experienced immediate relief.
