Healthwell Phenylalanine 500 is a dietary supplement consisting of the amino acid L-phenylalanine. This amino acid is essential, which means that it is needed in the body but we have to add it ourselves. Phenylalanine, like many other amino acids, acts as a building block in protein. One reason for eating phenylalanine is that the body converts it to tyrosine, an amino acid that affects neurotransmitters such as dopamine and adrenaline.

This is how L-phenylalanine works in the body
When we take phenylalanine, the body converts it into tyrosine, which in turn is part of the neurotransmitters dopamine, norepinephrine and adrenaline. Dopamine is a crucial substance for the brain's reward system and is one of the substances that make us experience feelings of happiness. Adrenaline is usually associated with various types of stress. It is secreted during both physical and mental stress to signal to the body that it is time to get ready to fight or flee. Through adrenaline, performance can be temporarily increased.
Phenylalanine in food
Because amino acids are found in protein, it is also through protein-rich foods that you can get phenylalanine. Red meat, dairy products, eggs and avocados are all sources of protein, but it can be difficult to get enough phenylalanine if you do not eat these foods as often. The sweetener aspartame also contains phenylalanine, along with aspartic acid. It is a synthetic sweetener that is often used in various light products, which in such a case must be labeled with the information "Contains a source of phenylalanine".
Is phenylalanine dangerous?
Phenylalanine is an amino acid that is needed in the body, but as with most things, the right dose is best. At doses above 4 grams per day, some people experience headaches. However, people with the hereditary metabolic disease phenylketonuria (PKU) should avoid supplementation with phenylalanine. This means that the body lacks or has impaired function of an enzyme needed to convert phenylalanine to tyrosine, which causes an excessive level of phenylalanine in the body.
