A popular supplement that shortens men"s lives has been named

An international group of scientists has found that elevated levels of tyrosine — an amino acid found in protein-rich foods and popular supplements for improving concentration — may be linked to reduced life expectancy in men.

As reported by TUT.AZ with reference to the journal Aging, specialists from Hong Kong and the United States studied data from more than 270,000 participants in the large-scale UK Biobank project. The findings turned out to be alarming: high levels of tyrosine in the blood correlate with an increased risk of premature death.

According to the researchers' estimates, an excess of this amino acid can reduce men's life expectancy by approximately one year. Notably, no similar pattern was found in women.

As foreign experts explain, tyrosine plays a key role in the production of dopamine, adrenaline, and other neurotransmitters, yet its impact on aging processes remains poorly studied to this day. As one of the probable reasons for the identified association, scientists point to the substance's influence on the development of insulin resistance and its associated age-related diseases.

The authors of the study emphasize that the obtained results require additional confirmation. In the future, the researchers plan to determine whether dietary adjustments or other measures can safely regulate tyrosine levels and thereby influence longevity.
