Stress-Icon1 The need

Daily stress is defined as a physical, chemical, or emotional state that causes bodily or mental tension and may contribute to certain diseases. Everyone experiences many stressful events throughout life, which may be related to work, health, finance, family and more. Daily stress is not unique to a specific population, and high rates of stress are noted in all age groups. In the USA, 43% of women and 33% of men say their stress has increased in the last five years. PS is a safe and clinically proven ingredient that may be helpful to many people in coping with occasional stress.

Sport-Icon2 why ps ?

Daily stress, whether caused by a mental or physical event or situation, results in physical effects in the body, one of the most noted being an increase in levels of the stress hormone, cortisol. Studies conducted over the last 25 years highlight the effect of PS to relieve occasional stress. Intake of PS is known to lessen the increases in cortisol that were associated with mental (job interview, school exams) or physical (exercise) stress. Since PS is a safe dietary ingredient, supplements containing PS may provide an effective, alternative for those seeking to ease day to day stress.

PS was associated with reduced levels of stress hormones during a mock job interview
Stress, whether caused by a mental or physical event or situation, results in physical effects in the body, one of the most noted is an increase in the stress hormone, cortisol. The effects of PS supplementation on stress-induced increase in cortisol levels in blood and saliva were tested in a double blind, placebo-controlled study, in which 80 young adults took supplemental PS for a period of 4 weeks before exposure to mental stress. Levels of cortisol in blood, as well as saliva, were found to be significantly lowered in participants taking PS as compared to those taking the placebo supplement (Hellhammer, J. et al. Effects of soy lecithin phosphatidic acid and phosphatidylserine complex (PAS) on the endocrine and psychological responses to mental stress. Stress 7, 119-126 (2004).)

PS was associated with reduced levels of stress hormones during an arithmetic exam
Daily stress is an unwelcome companion for students, especially during periods of exams. The effect of PS supplementation on exam-related stress was tested in a double blind, placebo-controlled study, in which 48 undergraduate students took PS for a period of 30 days before undergoing a math exam. The expected increase in exam-related stress was found to be significantly lower in subjects taking PS as compared to those taking the placebo supplement (Benton, D., Donohoe, R. T., Sillance, B. & Nabb, S. The influence of phosphatidylserine supplementation on mood and heart rate when faced with an acute stressor. Nutr Neurosci 4, 169-178 (2001)).

Sport-Icon3 The solution

The minimal dose of PS that has been shown to be effective for occasional stress relief is 300 mg/day (Benton, D., Donohoe, R. T., Sillance, B. & Nabb, S. The influence of phosphatidylserine supplementation on mood and heart rate when faced with an acute stressor. Nutr Neurosci 4, 169-178 (2001)), although higher doses may be warranted at initiation of supplement intake. In clinical studies that tested the effects of PS in young adults and elderly people, benefits of PS intake were seen as early as 10 days after consumption (Starks, M. A., Starks, S. L., Kingsley, M., Purpura, M. & Jager, R. The effects of phosphatidylserine on endocrine response to moderate intensity exercise. J Int Soc Sports Nutr 5, 11, (2008).). PS is produced from a natural source and is a safe dietary ingredient that has been linked to reduction of hormones related to physical and mental stress.
