## Description

L-Phenylalanine is an essential amino acid. Nutricost's L-Phenylalanine contains 180 capsules of L-Phenylalanine for 180 servings. Each serving is just one capsule containing 500mg of L-Phenylalanine. Nutricost, located and headquartered in the USA, only uses the best ingredients to ensure maximum quality and to help you feel your best! By keeping our supplement recipes simple and clean, you get the best experience possible with Nutricost. Our supplements are manufactured in a GMP-compliant and FDA-registered facility; and each batch of every product is tested by independent, ISO-accredited laboratories.

Review: A great boost! - I noticed this amino acid was in several focus and energy supplements so I decided to try it straight and wow, it works great! I take it only on days when I need extra energy or am operating on limited sleep and it provides a nice boost for 4 to 5 hours. I empty out about a third of the capsule since a full one can give me a little head tension and it is perfect. My system tends to be more sensitive to stimulants so I don't know if others get the same pronounced effect, but given the low cost and minimal side effects I recommend trying it out.
Review: Excellent product! - Excellent product!

Excellent product!

### ⭐⭐⭐⭐⭐ The Magic Molecule of Motivation
*by F***S on January 8, 2024*

These are great if you need a supplemen tohel maintain focus and drive. So many less headaches and feeling bad than drinking diet soda which essentially contains this as well to make you more addicted. I strongly suggest a book on amazon by Nootropics Expert David Tomen or his free blog.
