Phosphatidylcholine (PC) and Phosphatidylserine (PS) supplementation may enhance athletic performance. Exercise can deplete choline, and PC or PS may help maintain cellular function and improve endurance during intense physical activity.

Area of Science:

  • Nutrition Science
  • Exercise Physiology
  • Biochemistry

Background:

  • Phospholipids, including Phosphatidylcholine (PC) and Phosphatidylserine (PS), are vital for cellular structure and function.
  • Intense exercise can challenge physiological systems and potentially deplete circulatory choline concentrations, impacting performance.
  • Choline is a precursor to the neurotransmitter Acetylcholine, suggesting a link between choline levels and athletic capabilities.

Purpose of the Study:

  • To investigate the effects of Phosphatidylcholine (PC) and Phosphatidylserine (PS) supplementation on athletic performance.
  • To explore whether PC supplementation can mitigate exercise-induced choline depletion and enhance sporting outcomes.
  • To assess the impact of PS supplementation on physiological markers and perceived well-being during and after exercise.

Main Methods:

  • Review of existing studies on PC and PS supplementation in athletes.
  • Analysis of data on acute oral PC supplementation (0.2 g/kg body mass) and its effect on performance.
  • Examination of results from short-term soy-derived PS (S-PS) supplementation (750 mg/day for 10 days) on exercise capacity and recovery.

Main Results:

  • Acute PC supplementation demonstrated performance improvements in activities depleting circulatory choline.
  • Short-term S-PS supplementation attenuated cortisol, improved well-being, and reduced muscle soreness.
  • S-PS supplementation enhanced high-intensity cycling capacity and tended to improve intermittent running performance.

Conclusions:

  • Dietary interventions increasing PC and PS intake may benefit certain athletes.
  • PC supplementation shows potential for enhancing performance when exercise leads to choline depletion.
  • PS supplementation may offer benefits for exercise capacity, recovery, and overall well-being in athletes.
