What is Tyrosine used for, and does it work?

People use Tyrosine for many reasons, but the evidence varies by use. According to the Natural Medicines database, there is at least some clinical evidence supporting Tyrosine for Phenylketonuria (PKU), Cognitive function and Memory. For most other uses it has been studied for, the evidence is currently insufficient to rate. See the graded list on this page, and always confirm with your pharmacist or doctor.

What is L-Tyrosine used for?

People most often take it to support mental focus, mood, and the ability to cope with stress, sleep loss, or other demanding situations. The strongest evidence is for short-term mental performance under stress, while everyday benefits are not well proven.

Is Tyrosine safe to take?

It is generally well tolerated by healthy adults for short-term use, with mild possible side effects like nausea or headache. Long-term safety is not well studied, so it is best to check with your pharmacist or doctor first.

Can I take Tyrosine if I am pregnant or breastfeeding?

There is not enough safety information, so supplemental Tyrosine should be avoided during pregnancy and breastfeeding unless your doctor specifically recommends it. Getting Tyrosine from a normal diet is not a concern.

Does Tyrosine improve focus and energy in healthy people?

The evidence is mixed. It may help maintain mental performance when you are stressed, sleep-deprived, or in extreme conditions, but it is not clearly proven to boost focus or energy in well-rested, healthy people.
