Best L-Trytophan Powder
Posted by Reviewer2069206 on Apr 03, 2011
I found this product pretty effective for helping to get to sleep.

I'm a chronic insomniac and I started taking 2g an hour before bed, on an empty stomach, a week ago. Already, I'm sleeping better and I am no longer struggling through the days, yawning continuously. (my sleep hasn't been perfect, hence the 4 star rating, but maybe I haven't been taking it long enough) Powder is difficult to mix, however it doesn't taste too bad.

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.

Did not provide myself with the benefits claimed.

Seems to help me sleep. It doesn't dissolve as well as I would like in water. I will try it in a warm liquid in hopes that will work better.

I used this several times over the past couple of weeks it seems to calm me down more than make me sleepy.

I have used Tryptophan for the past few weeks and think it has helped my sleep patterns/mind but also to assist in digestion as well. Overall not a bad product
See no advantage over straight Melatonin

Did not think it worked as well as Melatonin for getting to sleep. Also it really does not mix well with either water or juice.
Good for extra energy

This is the first time ordering the powder, I find it doesn't mix well with any liquid I've tried Residue clings to the bottom and side of glass after your done drinking Back to the capsules for me

I combine the tryptophan with lysine, niacin, hops ginger and gaba and get only modest results. If you have a better formula with some strong rated results, please let me know. Thank You
