Why Do Dieters Use It?*

Some dieters say that L-tyrosine helps stimulate weight loss.

What Do the Advocates Say?*

Since it is a precursor to substances like epinephrine, norepinephrine, and dopamine, L-tyrosine may be a good supplement choice for those trying to lose weight because, theoretically, it may help speed metabolism. However, it should only be considered for people who also suffer from symptoms such as fatigue and depression.

There are no studies specifically showing that L-tyrosine helps to promote weight loss.

L-tyrosine is best taken without food. Because it can be stimulating, especially when used in large amounts, it should not be taken in the evening. As is the case when supplementing with any individual amino acid, it's possible to upset the balance by taking just one.

*Dieters and weight-management advocates may claim benefits for this supplement based on their personal or professional experience. These are individual opinions and testimonials that may or may not be supported by controlled clinical studies or published scientific articles.
