Product Overview

Description

  • Science-Based Nutrition

D-phenylalanine is a non-protein amino acid related to the essential amino acid L-phenylalanine. D- and L-phenylalanine are structural mirror images of each other. A small amount of D-phenylalanine may be converted to L-phenylalanine in the body. D-phenylalanine is reported to inhibit an enzyme that degrades enkephalins, which are naturally occurring substances in the body that belong to the class of compounds known as "endorphins".

No real results except dizziness

Posted by iHerb Customer on Nov 10, 2017 | Verified Purchase

I guess this works or not depending on individual situations. 500 mg is too much for me and resulted in dizziness. I tried the suggestion of another reviewer and took half doses, which relieved some of the dizziness. However, after 2 weeks, I'm experiencing zero results otherwise. I'll keep taking half doses until the bottle is gone just to find out if this stuff works at all once it builds up in the bloodstream. I'm glad this works for others and commend Doctor's Best for making it available.

Thanks for your feedback!

I suffered from 1 year depression. I was taking 5-htp, with no results. But when I start to took 1 capsule of this in the morning, my depression did disappear in two days. Unbelievable.
