What is Phosphatidylserine best known for in terms of its effects?

Phosphatidylserine is best known for its ability to blunt exercise-induced cortisol levels, which is significant for athletes and those engaging in intense physical activity. Cortisol is a stress hormone that increases in response to strenuous exercise, and while it plays a role in various bodily functions, elevated cortisol levels can have detrimental effects such as muscle breakdown, increased fatigue, and hindered recovery. By reducing cortisol levels post-exercise, phosphatidylserine may help mitigate these negative impacts, promoting better recovery and potentially enhancing overall performance and well-being.

This unique property of phosphatidylserine makes it particularly beneficial for athletes looking to manage stress and improve recovery times after workouts. In contrast, the other options focus on areas where phosphatidylserine does not have a well-established scientific basis for effectiveness. While muscle mass increase, bone growth, and testosterone boosting are important in sports nutrition, they are not the primary recognized roles of phosphatidylserine.
