Good product, but not for me
Unfortunately, my body did not adapt well to this product. Even taking it as directed on the package, I feel there was a reverse effect, in that I felt stressed when sleeping. However, for my husband it has worked. He has reported that it helps him to be calm during the day and relaxed at night. Not all supplements will have the same effect as bodies are different. I am glad it has worked for him, however unfortunately it has not worked for me.

Good
I often buy tryptophan because it helps me in recovery and development, I also notice its benefits with a good rest (better sleep quality; I use melatonin, too). In hard training cycles it is a must in my basket. Good price and quality.

Happy with this purchase, since I bought and consume it, it helps me to rest much better at night, combining it with melatonin and magnesium.

In search of restful sleep
Since I opened my business I started to incorporate supplements to help me have a more restful rest. Although, miracles to Fatima, I have been trying different supplements and I can not say that this one is better than others, since both melatonin and Sleep Care have been better than this one separately.

With melatonin
I take it with melatonin and it does seem to be working for me.
Info
The crossed-out price or the one shown as "PVPR" on our website is not a value arbitrarily estimated by HSN. This amount strictly corresponds to the official list price recommended by the manufacturer (or by our product development department in the case of own brands) for individual sale in the general retail market.
This information is used solely as an informative reference to allow the consumer to compare our current price with the standard market price suggested for a product of that category and quality.
Why is our price much lower? The large difference you perceive is not because the PVPR is inflated, but due to our business model. At HSN we operate under a Fair Price policy based on our business model with the elimination of intermediaries (Direct-to-Consumer Model).
The PVPR reflects the cost the product would have if it went through the traditional distribution chain (Importer > Wholesaler > Physical Store).
By purchasing on our website you acquire the product while avoiding those added costs. Therefore, the "discount" shows the structural savings we offer versus the industry's standard recommendation.
