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 also sold as a supplement for boosting focus and mental performance, making the finding especially intriguing.

Popular brain supplement linked to shorter lifespan in men Science News from research organizations Popular brain supplement linked to shorter lifespan in men A common amino acid found in protein-rich foods and supplements may be linked to a shorter lifespan in men. The results raise intriguing questions about protein intake, tyrosine supplements, and whether this common amino acid plays an overlooked role in aging.

Zhao, Yitang Sun, Junmeng Zhang, and Kaixiong Ye from the University of Hong Kong and the University of Georgia examined whether phenylalanine and tyrosine, two amino acids involved in metabolism and brain function, are connected to lifespan (lifespan). Their results point to a notable difference between men and women. Higher tyrosine levels were associated with shorter life expectancy in men, while no significant effect was detected in women.

The findings could eventually help scientists better understand why aging and longevity differ between the sexes, although much more research is needed before the results can be translated into health recommendations.
