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.

“Tyrosine is the amino acid building block for two neurotransmitters. Plus it is one of the building blocks for the adrenal and thyroid. I take it every morning to support my energy and focus.”
– Daniel G. Amen, MD



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.

I can focus at night!

I've been taking Tyrosine for 5 - 6 weeks. My day time focus is improving; I noticed, night time focus within 1 - 2 weeks, (which was non-existent before taking Tyrosine). It really works!

Won't live without it!

I take this product every morning before my feet hit the floor. It's the one thing that helps my brain get into gear in the morning. :)

Help for Peak holiday driving

I reviewed this product earlier, but I must say it is my most favorite product so far! My son, a FedEx driver, does not leave home without it! He said he definitely feels the difference!

Great product!

I take this every morning! It gives me the pick up and go that I need to get my brain going! A great product!

Gives me an added boost that helps me to accomplish tasks.

Tyrosine gives me that added boost. I feel energized and better able to apply myself to whatever I'm doing.

So far so good!

Just started taking this and see a noticeable difference in stress relief. Very helpful!

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.
