New research involving over 270,000 people shows an unexpected relationship between the amino acid tyrosine and men's lifespan. Tyrosine occurs naturally in protein-rich foods and is often used as a supplement for better focus and energy. However, the study shows that higher levels of this amino acid in the blood are linked to a shorter life expectancy in men, with a difference of nearly a year.
Tyrosine is a building block of proteins and plays a role in the production of important substances in our body, such as dopamine. It is therefore sometimes taken to improve concentration and alertness. However, this study warns that an excessively high level in the body may have negative effects, especially in men.
The study underlines the importance of caution when using food supplements. Not all substances that the body uses are necessarily beneficial for long-term health or lifespan. It is always a good idea to discuss supplements with a doctor or specialist first, especially as one ages.
These findings are relevant because they show that nutrients play a more complex role in healthy ageing than is often thought. For men, it may be wise to avoid extra tyrosine via supplements or to monitor it closely.
