Carlyle L Phenylalanine Supplement 1000mg | 200 Capsules | Non-GMO & Gluten Free

It’s a pill so it doesn’t really have any flavor, but this proves to be quite a good anxiety stress controller for me. I suffer from an illness that causes anxiety and also a great deal of muscle bone and joint pain. It seems to be working well my moods a lot better and I don’t have too much stress

Shipped and arrived on time. Capsules are not too large so they are easy to swallow for a 500mg capsule.

3 stars because I'm sure this is a quality brand. 1 star taken away because of magnesium stearate and another because it doesn't work. Something is wrong with these companies supply of l-phenylalanine. Like someone else said, back in the day this used to be a great supplement for mood, motivation, etc. It was consistent and worked fast. Now, several brands over the years I've tried don't do anything. Even the brand I had been taken regularly just stopped working like it was a sugar pill.

While this was recommended by a doctor, I found it did nothing and is a total waste of money. In addition to the lack of any appreciable results, this product sorely lacks in quality control from the manufacturer. Wanting to give it a appropriate trial, I have taken the product for several weeks and now that I'm further into the bottle, I have come across many capsules that are only partially (1/2 or less ingredients) filled. I'm getting rid of the remainder of this product! DON'T WASTE YOUR MONEY!

I use one, sometimes two, sublingually every morning. It's considered a very effective nootropic that goes right to the brain. It doesn't only make one feel alert but also a feeling of well-being.

Yep very effective

Works great!

I only took one and I was up and running. You better make sure you eat 'cause it messed up my stomach.
