    Good for Depression

    Posted by Reviewer1134057 on Jul 31, 2011

    I am taking these at night. I needed a prescription to import them into NZ, but they have been great. A bonus in they help maintain good sleep. I am now almost weaned off SSRI, which have many side-effects and must be slowly weaned off from.

    Many years this wasn't even available, and this price and dosage is great. I love this brand and how it is in veggie caps with no icky exipients!

    better night's sleep

    Posted by healthy-in-a-toxic-world on Aug 22, 2011

    Bought these for my 66 year old father who had been suffering from interrupted sleep for years (frequently waking up at 4am and remaining awake until 6am). by the 2nd night of taking 2 capsules before bed he reported a 'noticeably deeper sleep'. 2 weeks on and my dad is still taking them and still enjoying a deeper quality of sleep, feeling more rested in the mornings.

    Tryptophan Benefits

    Posted by Reviewer1949452 on Sep 28, 2011

    Very good product,should defintately be sold worldwide. not many people seem to know about this, but most definately helps with the sleep process, and then with daytime activities to give you a much more positive outlook. Defintately will continue to use, as i much prefer the natural choice instead of doctors rx.

    Great sleep aid

    Posted by Reviewer2595069 on Nov 03, 2011

    Use it as a sleep aid when I am over tired or restless. Helps with restless legs too. And you don't wake up groggy.
