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 comprehensive study involving more than 270,000 individuals has revealed a potential link between the amino acids phenylalanine and tyrosine, and the lifespan of men, according to researchers from the University of Hong Kong, the University of Georgia, and the UK Biobank. The findings, published in Aging-US, indicate that higher levels of tyrosine may be linked to a shorter life expectancy in men, while no significant impact was observed in women.
The research, which employed two complementary approaches, suggests that tyrosine could potentially decrease male lifespan by nearly one year. Despite the importance of these amino acids in protein production and neurotransmitter creation, the mechanisms behind this association remain unclear. Further investigation is needed to determine if dietary changes could safely modify tyrosine levels and promote healthier aging.
