Excellent value

The powder form of tryptophan is more of a value if you use it nightly and need to take more than one dose to fall asleep. I have been using this for the last year and it has totally brought me back to a normal sleep pattern. I wake up feeling rested. Also has me feeling better emotionally. I tried the Now brand of tryptophan but it did not work for me as well as Doctor's best.

Bait & Switch For Same Quantity On Re-Order

Purchased at iHerb

Placed a re-order for this item, but in the 100g size as on all of my previous orders, and received 50g size for same price. Called IHerb "customer service", and was rudely told "that's the price now, or you can send it back". No answer to my polite inquiry, and no explanation. The product is fine, but I'll seek other sources next time.

Good product but hard to swallow

I gave this three stars only because it does not mix well in water and tastes awefull. But it does help with better sleep. It is cheaper than capsules but I think I will spring for the capsules next time. If you have a capsule filling machine you could try that approach and not have to deal with mixing and trying to get it down your throat. It can be time consuming. L-tryptophan is a precursor to 5-HTP. Some people find that 5-HTP does not work so well for them. If this is you, L-tryptophan is a good alternative. Try it with a small amount of B6 and B3 as they are cofactors and it may work better. If you found this review helpful, kindly visit my home page and see more value added reviews. Peace and good health.

Mild, if any, effects

Posted by Reviewer1372184 on Jan 15, 2007

Purchased at iHerb

I have a pretty severe anxiety/panic disorder. I am extremely open to "natural" treatments for my condition. I am sorry to say that this tryptophan product has extremely mild effects on my anxiety, even at higher doses. I have taken up to 3 grams at a time, and at most I feel a slight decrease in anxiety. It is similar in its effects to St. John's, SAM-e, kava, magnesium, and many of the other natural standards for anxiety/depression I have tried. Unfortunately, benzos, SSRIs, SNRIs, tricyclics, and the like are far more effective for me than are treatments such as this l-tryp. Perhaps this just is not a good brand. However, I have tried two other brands of l-tryp with similar results. Also, this brand has a horrific taste, even when mixed with something sweet. That's my two cents.

Depression

Posted by Reviewer2260549 on Nov 18, 2008

Purchased at iHerb

I bought this for my mom for her depression. After lots of research I found this is the best brand. I like the powder vs the capsules because the caps are 500 mg and the powder is a 500 mg scoop but you can use 1/2 the scoop or whatever amount you want to control the dosage. My mom only takes 1/2 a scoop at night and she is really liking it for her depression and improved sleep.
