Provides l-tyrosine, an amino acid that the brain, adrenals, thyroid and other organs use to make neurotransmitters that are crucial to emotional balance and adaptability, especially when under mental strain.



For support of the brain, adrenals and thyroid, especially when coping with stress or intense mental strain

Promotes Healthy Emotional Balance
Tyrosine is a precursor (starting molecule) for the catecholamine neurotransmitters dopamine (DA) and norepinephrine (NE). The brain needs DA especially for working memory ("multitasking"), and NE especially for cognitive adaptability. NE and DA operate in synchrony with the brain's other neurotransmitters to promote healthy mood, behavior and mental focus.

Supports Mental Focus Under Stressful Challenge
Stress, or sometimes just intense mental effort, intensifies brain activity and depletes supplies of DA and NE. The brain has special transport enzymes that import l-tyrosine across the blood-brain barrier, as needed to replete DA and NE. In a double-blind clinical trial, a 2-gram dose of tyrosine helped undergrad students perform better at multitasking, to "make the right choices" under mental challenge.

Supports Healthy Adrenal Gland Function
Emotional intensity or stress stimulates the adrenals to release NE, and E (epinephrine, adrenaline) that they make from NE. This NE helps the brain cope with the challenge. The adrenals also rely on DA for their normal stress response. Healthy adrenal function requires ample l-tyrosine to sustain their production of DA, NE and E.

Supports Healthy Thyroid Gland Function
The thyroid makes the hormone thyroxine (tetraiodothyronine, T4). This hormone helps regulate the body's energy metabolism, but when under stress may make less T4. The brain needs l-tyrosine in order to regulate the thyroid to ensure T4 production.


Very happy

I love all the things that this vitamin supports. We don't even realize in our everyday lives that we need this extra help to improve our everyday tasks. Some people struggle from adrenal fatigue and don't even know it! I have definitely noticed a difference in my memory and in multitasking. I've only been taking this a month so let's see how much more I improve!

It works.

I feel an extra boost at the gym daily. Plus increased energy/focus upon wake up.

I will always take this now!

After listening to Dr. Amen's book on Healing ADD and hearing how important this amino acid is, I immediately started looking into it and ordered from this website a couple weeks later. I've taken this since April 2017 and I can tell you the amazing difference I feel. This is one of 5 supplements from Dr. Amen I take every day and I can't imagine going back to how it was before I started this regimen.

It works!

I've been taking Tyrosine 5+ months. I knew it was helping. Last week, I was off schedule and missed the second daily dose of Tyrosine. I am amazed at how much difference it makes in my afternoon and early evening focus. Without the second dose, it was very difficult to complete the smallest tasks ... I had lots of tasks started but very few complete. I'm back on schedule taking the second dose, and am again able to focus in the afternoon!

I like this product.

This is a great product. I feel great when I take it 2 times a day. It helps me feel happy and focused.

Love the clarity of thought.

To me taking this first thing in the morning usually before my feet hit the floor clears the cob webs of sleep and gets me thinking clearer and more focused than without it .

Ingredients & Facts

  • Tyrosine
    Tyrosine (technically, l-tyrosine) is an amino acid that is a building block for proteins but also a precursor (starting molecule) for two very important catecholamine nerve transmitters: dopamine (DA) and norepinephrine (NE). Both are essential for cognition and for the brain's "executive" functions that include making decisions. DA is essential for attention, for working memory (roughly equivalent to multitasking), and generally for cognitive flexibility. NE helps control the brain's timely adaptability to rapidly changing circumstances, and the two work synergistically to support the brain's executive functions. The adrenal glands also need tyrosine, to make DA, NE and E (epinephrine, adrenaline) for their important role in coping with stress. The thyroid gland needs tyrosine to make the hormone thyroxine, and is also vulnerable to stress. Supplementing with Tyrosine from BrainMD Health helps ensure adequate supplies of l-tyrosine to the brain, adrenals, thyroid, and other organs.

Frequently Asked Questions

How do I know whether I need this supplement?
Different people vary widely in their DA, NE and E status. Extensive animal and human research indicates that intense mental effort, especially when maintained over periods of days to weeks, can deplete these crucial brain transmitters. The more busy you are and the more mentally strained, the more likely you are to need Tyrosine.
What's the best way to take this supplement?
It's very important to take Tyrosine a couple hours away from food, because certain amino acids from proteins you've recently digested can compete with l-tyrosine for the brain's transporters and block its delivery to the brain.
How much should I take for best results?
A good maintenance dose is 2 capsules once or twice daily between meals. Depending on their pace of life some individuals may benefit from substantially higher intakes, as recommended by a nutritionally-informed physician.
Can vegetarians take this product?
Yes, it is suitable for vegetarians and vegans.
