L-Phenylalanine Performance Supplements

Our 1000mg L-phenylalanine nootropic supplement is designed to help accelerate muscle growth, increase weight loss, sharpen your mind, and uplift your mood. 

Phenylalanine is an essential amino acid used to help your body synthesise proteins and produce dopamine. Your body can produce some of it on its own, but not enough to meet its needs.

The Science

Scientists have observed that L-phenylalanine supplements can help users to regulate their appetite, lower feelings of stress and fatigue, and combat negative emotions.

L-phenylalanine helped to release more cholecystokinin, significantly reducing feelings of hunger.

The reduction in food intake after Phenylalanine (PA) was associated with a greater sensation of fullness compared with placebo, and this finding is in keeping with the proposed action of Cholecystokinin (CCK) - hormone which increases satiety - in reducing food intake.

Taking L-phenylalanine is believed to help relieve feelings of hunger, helping to cut down on food intake. A 2017 study found that L-phenylalanine helped overweight subjects cut down on their calorific consumption and lose weight.

L-phenylalanine is a natural molecule used in the body's everyday functions. However, individuals with phenylketonuria should avoid taking it as a supplement, as their bodies cannot properly metabolise it. This condition is usually diagnosed at birth.

L-phenylalanine is a precursor to many important neurotransmitters that are used to help the brain function at its best. This means that taking l-phenylalanine could help to keep you focused, energised, and alert. That being said, there is no evidence or research available to suggest that it interferes with your sleep.
