What has Huberman said about L-Tyrosine?

Andrew Huberman has discussed L-tyrosine extensively on the Huberman Lab. Here are the key points he has made:

1. Increases Dopamine:

   • L-tyrosine is an amino acid that serves as a precursor to dopamine, enhancing alertness and focus. It boosts dopamine levels about 30 to 45 minutes after ingestion, with effects peaking and then dissipating after roughly 30 minutes 1.

2. Uses and Dosage:

   • It is commonly taken in capsule or powder form, with typical doses ranging from 500 to 1500 mg. This can improve focus and motivation, though it requires caution, especially for those with mood disorders or anxiety 2 3.

3. Effects and Risks:

   • While effective for enhancing focus and alertness, it can cause a crash once dopamine levels drop. Hence, it's important to avoid overreliance on this supplement. Dr. Huberman suggests using L-tyrosine occasionally rather than regularly to prevent dependency and manage the inevitable drop in dopamine 1 4.

4. Combining Substances:

   • For focus improvement, he combines L-tyrosine with substances like Alpha-GPC and caffeine, and takes them early in the day to avoid sleep disturbances. He emphasizes the importance of trying individual ingredients before combining them to understand their effects 5 6.

5. Specific Recommendations:

   • Andrew Huberman personally takes 500 mg of L-tyrosine combined with Alpha-GPC and coffee for enhanced focus during workouts or mental tasks, usually four days a week 5.
   • He advises starting with low doses (250-500 mg) and adjusting based on body weight and individual response, ensuring to monitor any subsequent crashes or side effects 3.

6. Scientific Support:

   • A 1983 study demonstrated that L-tyrosine increases dopamine specifically, ruling out placebo effects. However, sustained high dopamine levels can lead to an eventual below-baseline drop, warranting careful and occasional use 1.

Overall, Andrew Huberman endorses moderate, cautious use of L-tyrosine for specific purposes like boosting focus and motivation, while being mindful of its potential downsides.
