HelloPharmacist Scorecard of L-Tyrosine Brain Support 1000 mg by New Age
Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.
What’s inside
Full disclosure
This product contains one active ingredient: L-tyrosine at 1,000 mg per capsule. Tyrosine is an amino acid your body uses to make neurotransmitters and thyroid hormones.
The capsule itself is filled with gelatin, magnesium stearate (a vegetable-grade lubricant), and rice powder as inactive ingredients.
Does it work?
Moderate evidence
L-Tyrosine has established effectiveness for phenylketonuria (PKU), a genetic condition where the body can't process another amino acid. For cognitive function and memory, the evidence suggests it may help — though the data isn't conclusive.
For athletic performance, it appears ineffective. For alcohol use disorder and dementia, we don't have enough reliable evidence yet to know whether it works.
How safe is it?
Well-documented data
L-Tyrosine is generally well tolerated in healthy adults, but talk to your healthcare provider before using it regularly. Possible side effects include fatigue, headache, heartburn, and nausea — most people taking standard doses don't report serious problems.
However, safety data isn't complete. During pregnancy and breastfeeding, there isn't enough safety information on file, so talk with your doctor or pharmacist before using this supplement if you're pregnant or nursing.
Meds to double-check
Moderate interaction found
Before starting this product, check with your doctor or pharmacist if you take levodopa (Parkinson's medication) or thyroid hormone medications like levothyroxine — both interact at Moderate severity. Tyrosine and levodopa need to be spaced at least 2 hours apart, and thyroid hormones may have their effects amplified by tyrosine.
The bottom line
Scorecard at a glanceFully disclosed formula with some supporting evidence for its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.
L-Tyrosine may support memory and thinking in some people and is established for PKU. If you take levodopa for Parkinson's disease or thyroid hormone medications, check with your doctor or pharmacist first — spacing doses apart may be needed.
It's generally well tolerated, but talk to your healthcare provider before regular use, especially if you're pregnant, breastfeeding, or have a medical condition.

L-Tyrosine Brain Support 1000 mg by New Age Drug Interactions
HelloPharmacist Interaction Report
L-Tyrosine Brain Support by New Age can interact with medications you might already be taking.
The main concerns are levodopa (used for Parkinson's disease) and thyroid hormone medications — both are Moderate severity interactions. Tyrosine and levodopa compete for absorption in your gut, which can make levodopa less effective; if you take both, separate them by at least 2 hours.
Tyrosine is a building block for thyroid hormone, so taking it alongside thyroid medications might boost hormone levels too much.
Read the full breakdown — every affected drug type, severity by severity
Although we've identified interactions with these drug types, we hold interaction data only for levodopa and thyroid hormones in our monograph for tyrosine. Altogether, these interactions span 21 individual medications.
If you take any prescription medication — especially for Parkinson's disease or thyroid conditions — use the medication checker on this page to look up your exact drugs before you start this supplement.
