What is Mitohormesis?

Mitohormesis refers to the process by which mitochondria produce small amounts of reactive oxygen species (ROS) that act as signaling molecules. These signals initiate cellular mechanisms aimed at safeguarding the cells from various stressors. The International Review of Cell and Molecular Biology defines mitohormesis as:

“a biological response where the induction of a reduced amount of mitochondrial stress leads to an increment in health and viability within a cell, tissue, or organism.”

Research indicates that activating this mitohormetic response may enhance lifespan across various animal models. The process is influenced by factors such as ROS, mitochondrial metabolites, and the release of mitokines. Although the concept of mitohormesis is relatively new, it has garnered attention from scientists exploring its potential therapeutic applications.

While the initial findings are promising, it’s important to recognize that the field is still developing, and conclusive results may take time to materialize.

Importance of Mitochondrial Health

My interest in mitochondrial health has led me to discuss related concepts such as mitophagy and mitogenesis in earlier articles.

I emphasize mitohormesis due to the beneficial effects of N-Acetyl L-Tyrosine on this crucial cellular process. A 2020 study published in Embo Reports suggested that “N-Acetyl L-Tyrosine serves as a vital endogenous molecule that can trigger mitohormesis.”

My Journey with N-Acetyl L-Tyrosine

My understanding of tyrosine dates back to my studies on its role in neurotransmitter synthesis. Tyrosine is synthesized from phenylalanine and acts as a precursor for various neurotransmitters and hormones, including dopamine and adrenaline.

After encountering N-Acetyl L-Tyrosine (NALT) during my research on cognitive enhancers, I became intrigued by its purported increased bioavailability. Observing its use by knowledgeable friends in the biohacking community encouraged me to try it, particularly for counteracting the effects of sleep deprivation during demanding tasks, such as conference presentations.

Between 2000 and 2020, I traveled frequently as a speaker and dealt with jet lag, often using melatonin to address this. While melatonin was effective, I often felt sluggish afterward. My reliance on coffee, which eventually caused digestive issues, led me to explore N-Acetyl L-Tyrosine as an alternative.

After taking approximately 350 mg, I experienced heightened alertness and focus without any adverse effects.

Functions, Benefits, and Applications of N-Acetyl L-Tyrosine

Although tyrosine has a robust research background, N-Acetyl L-Tyrosine is relatively new, showcasing additional advantages due to its acetylation. Comprehensive research is documented in resources such as the National Library of Medicine, detailing its effects on neurotransmitter levels.

The primary role of NALT is to enhance neurotransmitter production, including dopamine and norepinephrine. While research on NALT is limited, various studies support the cognitive benefits of tyrosine supplementation, particularly under stress.

One notable paper reviewed 15 studies and found that tyrosine supplementation can counteract cognitive decline in stressful situations. This underscores its potential to enhance cognitive flexibility, attention, and working memory, although effects on physical performance appear limited.

For instance, a 2011 study involving children with ADHD noted significant improvements in symptoms among those treated with tyrosine. While ethical concerns led to its retraction, the findings remain accessible in original journals.

A 2014 study indicated that tyrosine may enhance cognitive function during exercise in hot conditions, further supporting its diverse applications.

Conclusion and Final Thoughts

Tyrosine is categorized as a non-essential amino acid, synthesized from phenylalanine, making supplementation particularly beneficial for those unable to process phenylalanine effectively. However, caution is warranted, especially for individuals with elevated thyroxine levels.

While low doses of tyrosine are generally safe, larger amounts may lead to side effects such as headaches and nausea. My experience with N-Acetyl L-Tyrosine has been positive, and I prefer obtaining tyrosine through food sources like cheese, meats, and eggs.

As with any supplement, it is crucial to consult with healthcare professionals before starting a regimen, as potential interactions and side effects need to be considered.

Thank you for exploring my insights. Wishing you a healthy and fulfilling life.
