Helps anxiety, depression and pain

10 people found the following review helpful

Posted by Reviewer2575097 on Aug 25, 2010

Purchased at iHerb

Some people have a deficiency of serotonin which causes depression and anxiety, but having an endorphin deficiency can also cause depression and anxiety. This helped restore my endorphin levels to normal, which helped my depression a bit but also helped my anxiety HUGELY, in fact this is about the most effective thing I have found for my anxiety. I have an arm injury which left me with long-term mild pain, it did help with this too, though the pain came back after I stopped taking D-Phenylalanine, I might not have taken it for long enough.

The D- Form without the L-Phenylalanine is hard to find. This really helps with pain. It definitely does something to help protect endorphins in your body.

I call these my new 'happy pills' ... really gave me a good feeling. Not a high of course, just a really good feeling about ... everything. It works better than dlpa for me.

I'm not so weepy when I take 2 per day. I take this product (plain d-phenylalanine) at times when the DL-phenylalanine makes me wired, or makes me wake up too early. This is neutral and doesn't make you wired OR tired.
