A major study of over 270,000 people has brought to light unexpected results regarding tyrosine, an amino acid that occurs naturally in protein-rich foods and is often used as a supplement to improve concentration. The study showed that men with higher tyrosine levels in their bodies had a shorter life expectancy on average. The difference amounted to almost a year less of life.
Tyrosine is a building block for proteins and plays a role in the production of important substances in the brain, such as dopamine. Therefore, it is often taken to support mental sharpness. However, this research finding suggests that extra tyrosine intake may not be without risk, especially in men.
Although the study shows a link between tyrosine levels and life expectancy, this does not directly mean that tyrosine is the cause. Several factors may be at play that influence the effect. It is therefore wise to be cautious with supplements and not simply start using extra amino acids without professional advice.
For people who want to age healthily, it is important to think carefully about what extra supplements they take. Natural food remains the best source of building blocks for the body. This research highlights that even substances that sound good, such as tyrosine, are not automatically better for our long-term health.
