​Unveiling the Truth Behind "L- Tyrosine Changed My Life"

Posted by Leonard Shemtob on Mar 26, 2024

Have you ever heard people say that L-tyrosine can totally change your life? Maybe you've seen it all over social media, like YouTube, TikTok, and Reddit. About two years ago, there was this big trend called 'L-tyrosine changed my life.' People claimed they felt happier, more energetic, and less stressed. 

But are these claims true? Let's find out!

In this article, I'll share my own experience with L-tyrosine and look at the science behind it to see if it's really as amazing as people say. 

Let's delve into the scientific foundation of Tyrosine, exploring its evidence-based benefits for overall health and well-being.

Short Summary

Understanding L-Tyrosine

L-tyrosine is a natural building block called an amino acid. Your body can actually make L-tyrosine on its own, but you can also get it from certain foods. It plays a special role in the brain by helping to create important chemicals like the feel good hormone and norepinephrine. 

These chemicals influence things like focus, mood, and energy levels. Because of this connection, some people are interested in whether taking L-tyrosine supplements can have any benefits for these brain functions.

How does it Work?

L-tyrosine boosts the production of neurotransmitters like the feel good hormone, adrenaline, and noradrenaline. These neurotransmitters affect mood, stress response, memory, and performance in stressful situations.

Benefits of L-Tyrosine

  • Enhanced Mood: L-tyrosine plays a role in producing neurotransmitters like the feel good hormone, which can lift our mood and make us feel happier and more positive.
  • Improved Focus and Mental Performance: By increasing levels of neurotransmitters in the brain, L-tyrosine may help sharpen our focus, concentration, and cognitive abilities, making it easier to tackle tasks and stay productive.
  • Reduced Stress: L-tyrosine is involved in producing stress hormones like adrenaline and noradrenaline, which can help us cope better with stressful situations and promote a sense of calmness.
  • Increased Energy Levels: As a precursor to important brain chemicals, L-tyrosine can boost energy levels and combat feelings of fatigue, keeping us feeling more alert and energized throughout the day.

Now, let's explore the scientific evidence behind these benefits:

1- Can Tyrosine Boost Motivation?

A study in the Journal of Psychopharmacology revealed that participants showed increased alertness five hours after taking tyrosine supplements. Additionally, studies on diets lacking tyrosine have linked reduced the feel good hormone levels to slower reaction times in tasks requiring alertness. 

When you anticipate a rewarding experience, your feel good hormones levels rise, triggering motivation and alertness. This response encourages you to take action and pursue the potential benefit. Conversely, studies suggest that lower the feel good hormone levels might contribute to decreased motivation and engagement.

2- Can Tyrosine Improve Mood?

Studies on tyrosine depletion have shown that it can lower mood, particularly in women experiencing mild seasonal mood changes. This suggests that an imbalance in the feel good hormone levels in the brain can negatively affect mood. 

L-tyrosine and 5-htp, a precursor to serotonin, have been extensively studied for their effects on serotonin and the feel good hormone levels. 

The feel good hormone is crucial in regulating mood and emotional connections in the brain. A study published in The Journal of Neuroscience in 2015 found that boosting the feel good hormone levels can lead to increased happiness, especially in response to rewards.

3- Stress and L-Tyrosine

Although not a relaxant, tyrosine shows potential in improving responses to acute stress. Research indicates that tyrosine may enhance decision-making in short-term stressful situations, especially when the feel good hormone levels are low, aiding in complex cognitive tasks. 

A military study demonstrated improved memory, tracking, and cognitive performance in cadets taking L-tyrosine during high-intensity training and heat stress. Additionally, studies suggest that L-tyrosine supplementation may enhance deep thinking, or convergent thinking, during multitasking creative tasks.

Potential Side Effects of Tyrosine

Tyrosine is generally regarded as safe when taken in recommended doses. However, there are some considerations to keep in mind and discuss with your healthcare provider:

  • Digestive Discomfort: Digestive discomfort may occur with a high dose. Consider dividing your doses throughout the day if you plan to take larger amounts.
  • Medications: Consult your doctor, especially if you take Parkinson's medication as they interact.
  • Thyroid Issues: Those with thyroid issues should consult their doctor before taking tyrosine, as it may affect thyroid hormone levels.

Tyrosine may be most effective when norepinephrine levels are low, such as during times of stress. If you're not experiencing stress, you may not fully benefit from its effects.
