Popular brain supplement linked to shorter lifespan in men
AI KEY TAKEAWAYS (TL;DR)
- A large study involving more than 270,000 people has linked higher blood levels of the amino acid tyrosine to a shorter lifespan in men
- Using both observational data and genetic analysis, researchers found that elevated tyrosine could potentially reduce male life expectancy by nearly a year, while no significant effect appeared in women
- Tyrosine is found naturally in protein-rich foods and is also sold as a supplement for boosting focus and mental performance, making the finding especially intriguing
