Popular brain supplement linked to shorter lifespan in men
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…
A study involving over 270,000 individuals from the UK Biobank suggests that high levels of tyrosine, an amino acid, may shorten life expectancy in men. Researchers from the University of Hong Kong and the University of Georgia found that while both phenylalanine and tyrosine influence metabolism and brain function, tyrosine appears to be linked to shorter lifespan in men, with an estimated one-year reduction.
Notably, women did not show a significant effect from tyrosine on their lifespan. The study also noted that men typically have higher tyrosine levels than women, which could partially explain the gender difference in average lifespan. The researchers caution that while tyrosine is commonly used as a dietary supplement for cognitive benefits, more research is needed to determine if lowering tyrosine levels through diet could extend lifespan in men.
