    Great Value

    Posted by Reviewer1921553 on Jun 08, 2007

    This tryptophan powder is an excellent value compared to the capsuled tryptophan supplements available. However, it can become a bit cumbersome to mix the powder with a drink every time you need to take it (but maybe I'm just lazy!). The product itself is great, I trust the Doctor's Best brand as well. When I do take it I am more easy-going during the day (but sometimes I don't because I don't have time to mix it into a drink). After I finish off my current supply I will get the Doctor's Best tryptophan in the capsules for more convenience.

    Works great. I use vitamins b6,amino acid lysine, niacin and some sleepy herbals with it. Seems like I dream more. Will reorder often.

    This seems OK, a bit bitter taste. I have not noticed a great improvement in my sleep, but I also have not been taking it very regularly.

    Works well but...

    Posted by Reviewer3297256 on Mar 02, 2009

    It works well but it's a little bitter so you really need to mix it into apple sauce or something w/similar texture if you don't drink fruit juice. I'm going to put the rest into my capsule maker.
