What's this test for?

This test is ideal if you're experiencing low energy, brain fog, low mood, or trouble focusing. Tyrosine is an amino acid your body uses to make important brain chemicals and thyroid hormone, so checking your level can help explain these symptoms. It's also useful if you follow a restrictive diet or have digestive issues that might affect how well you absorb protein building blocks like tyrosine.

What happens after I get my results?

Your results will show up in your account with your tyrosine level explained alongside the normal range, so you can see right away whether you're low, normal, or high. If your level is off, simple next steps like adjusting your protein intake or considering a targeted supplement are usually a good starting point, and retesting in a few months can show if things have changed. You can download a standard lab report from your account at any time, and the trends feature lets you track your tyrosine level over time to see how lifestyle changes are working.

What is tyrosine and why does it matter?

Tyrosine is a building block that your body uses to make dopamine, norepinephrine, and thyroid hormone — chemicals that affect your mood, focus, energy, and metabolism. When tyrosine levels are off, it can show up as fatigue, poor concentration, or a low mood. Keeping an eye on this marker gives you a window into how well your body is fueling these important processes.

How can I naturally support healthy tyrosine levels?
Eating enough protein-rich foods like eggs, chicken, fish, dairy, nuts, and seeds gives your body the raw material it needs to make tyrosine. Managing stress matters too, since chronic stress uses up tyrosine faster than normal. Getting good sleep and staying hydrated also help your body process and use amino acids efficiently, and some people find a tyrosine supplement helpful when diet alone isn't enough.
When will I get my results?
Results are typically ready within about 7 days of your lab visit. You'll get a notification as soon as they're posted to your secure online account, where you can view and download the full report.
Who should consider this test?
Anyone dealing with ongoing fatigue, poor focus, low mood, or suspected thyroid issues may want to consider this test. It's also worth checking if you're on a low-protein or restrictive diet, are under chronic stress, or want a baseline before making dietary or supplement changes. People tracking mental performance or energy levels over time may also find it useful.
What symptoms indicate I may need this test?
Common signs include persistent tiredness, difficulty concentrating, low motivation, low mood, and sluggish metabolism. Some people also notice these symptoms alongside thyroid-related issues like weight changes or feeling cold often. If these symptoms sound familiar, checking your tyrosine level can help you understand what might be contributing.
What does a high tyrosine level mean?
A high tyrosine level can sometimes point to a diet very high in protein or supplements, or in rare cases, a metabolic issue with how your body processes amino acids. It's usually not dangerous on its own, but it's worth looking at your overall diet and supplement use. If your level is significantly elevated, retesting and reviewing your intake is a reasonable next step.
What does a low tyrosine level mean?
A low tyrosine level may mean your diet isn't providing enough protein, or that ongoing stress and poor sleep are using it up faster than you can replace it. This can contribute to low energy, poor focus, and a flat mood. Increasing protein-rich foods and managing stress are practical first steps to bring levels back up.
How often should I retest?
If you're making diet or lifestyle changes to improve your tyrosine level, retesting every 2-3 months is a good way to track progress. If your first result was within the normal range and you feel fine, testing once a year or whenever new symptoms appear is usually enough. Use the trends feature in your account to compare results over time.

What this means

This tyrosine level falls within the normal range, meaning your body has adequate building blocks to make key brain chemicals and thyroid hormone. Levels can shift based on diet, stress, and sleep, so tracking over time is helpful. Staying in this range generally supports steady energy, mood, and focus.

* Regular blood test results (e.g., CBC) typically start arriving the next business day after sample collection. More advanced tests may take longer due to complexity.
