Peptides are isolated from whey proteins to deliver amino acids in a soluble and more bioavailable form. As such the amino acids can be directly absorbed and moved into the bloodstream. Tryptophan is the pre-cursor to serotonin, melatonin and niacin. In order to use tryptophan the body also needs sufficient supplies of vitamin B6. It might be sensible when taking tryptophan over the long-term to regularly add some B6. Tryptophan is most affective taken along side some carbohydrate (fruit or orange juice), this is because carbohydrates cause the body to release insulin which in turn helps to utilise tryptophan more easily. Personally when using this product I would say the effect from tryptophan is longer lasting. If I take normal pure l-tryptophan, the effect seems to last two hours after which I might feel worse; and I'm not planning on taking a capsule every two hours. If I take two tables of this at noon for example (500mg tryptophan in total), I feel good for the rest of the day; and even better in the evening. So my personal observation is indeed that this form is better utilized by the body!

I suffer from fibromyalgia which causes sleep disturbances such as restless legs, sleeplessness and sudden waking. This product has me yawning within a half hour and sleeping soundly. Highly recommended. Please note that I am using this product in conjunction with Life Extension Melatonin drops.

I used it about 1,5 week and I got the opposite effect. My mood ant sleep become much worse, although I dont use any medications, or drugs. I stopped use them and my state of health has returned to its previous state.

It works but tablets have bad taste.
