Summary of Healthtrekker.net Article: Tyrosine, Lifespan, and Extreme Supplementation
This article from Healthtrekker.net discusses a recent study suggesting a correlation between regular tyrosine consumption and a slightly reduced lifespan in men. here’s a breakdown of the key points:
The Study & Findings:
* Research: A study of over 720,000 men from the UK Biobank (conducted by American & Chinese researchers) found that higher tyrosine levels were associated with a shorter lifespan.
* lifespan Reduction: The current estimate is a reduction of approximately one year.
* Source of Tyrosine: the primary sources appear to be energy drinks and protein intake (as protein is a precursor to tyrosine).
* Phenylalanine: A similar amino acid, phenylalanine, did not show the same correlation with lifespan.
Why is this concerning?
* Popular Supplement: Tyrosine is a common ingredient in energy and focus-enhancing supplements.
* Stealthy Consumption: People often consume tyrosine through branded energy drinks, without fully considering the long-term effects.
* Potential Mechanisms: Researchers hypothesize that the link could be due to:
* Adrenaline/Stress: Tyrosine is a precursor to adrenaline and noradrenaline, potentially leading to chronic stress and accelerated aging.
* Insulin Resistance & Visceral Fat: Tyrosine might contribute to these health issues.
Broader Implications & Warnings:
* The “Biochemistry Casino”: The article highlights the risks of self-experimentation with supplements, citing other examples of vitamins and supplements linked to negative health outcomes (e.g., Vitamin E & prostate cancer, excessive vitamin D & cataracts).
* Food vs. supplements: The author suggests prioritizing obtaining nutrients from whole foods rather than relying on supplements.
* Protein Intake: The study suggests being mindful of protein intake, as it’s a significant source of tyrosine.
Energy Drink Brands Mentioned:
* Contain Tyrosine: Gorilla Mind Energy, Life Pro Stamina, 5-Hour Energy, EHPlabs oxyshred
* Do Not Contain Tyrosine: RedBull, AlaniNu, Reign, Ghost, Monster, Celsius (though these still contain stimulants like caffeine).
Overall Message: The article cautions against excessive supplementation and encourages a more mindful approach to nutrition,emphasizing the potential for unintended consequences even with seemingly harmless substances. It suggests that “burning too hot” (pushing the body to extremes with supplements) can have long-term health costs.
