Sport-Icon1 The need

Exercise is beneficial for both body and mind. Physical activity can be used to control weight, reduce the risk of cardiovascular and other metabolic diseases, strengthen muscles and bones, and improve mental health and mood.
There are, however, exercise-related phenomena that can make physical training less satisfying, and thus less effective. Muscles often become often sore after training, and a few days can pass until muscle fatigue allows for additional training. Recovery from exercise can also hold someone back from optimizing their training. There also is the “ceiling effect”, which is well known to those who train regularly: there’s a point where no matter how much you train, performance doesn’t seem to improve.
All these effects reduce the enjoyment of training, prevent optimization of a training regimen, and may even deter people from training altogether.

Sport-Icon2 why ps ?

While PS is known mostly for its effects on cognitive function, there are other effects that have been identified in humans. A number of clinical studies examining the effects of PS on exercise showed that intake of PS enhances the exercise experience by improving several different outcomes. These outcomes have included significant improvements to endurance (which can boost peak performance) (Kingsley, M. I., Miller, M., Kilduff, L. P., McEneny, J. & Benton, D. Effects of phosphatidylserine on exercise capacity during cycling in active males. Medicine and science in sports and exercise 38, 64-71 ) and recovery (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)), as well as reduced muscle soreness(Kingsley, M. I., Wadsworth, D., Kilduff, L. P., McEneny, J. & Benton, D. Effects of phosphatidylserine on oxidative stress following intermittent running. Medicine and science in sports and exercise 37, 1300-1306 (2005)).

PS effect on our muscles

Increased endurance means a person can keep training for longer periods of time. For example, those who run or cycle can keep going further and for longer, improving their results. In a double blind, placebo-controlled clinical study conducted using a model of cycling, PS was found to increase the endurance of the cyclists by 30% (Kingsley, M. I., Miller, M., Kilduff, L. P., McEneny, J. & Benton, D. Effects of phosphatidylserine on exercise capacity during cycling in active males. Medicine and science in sports and exercise 38, 64-71 (2006)).
Our body is influenced by many factors, some of them related to hormones found in our body, especially in the blood. Cortisol, a hormone known best for its relationship to stress, causes muscle wasting when present in high levels. Exercise leads to an increase in cortisol, which may reduce muscle mass buildup. Another hormone involved is testosterone, which is one of the most important hormones in the process of muscle building. In a clinical study, PS was found to reduce the increase in the levels of cortisol and simultaneously increase the levels of testosterone, leading to a more optimal hormonal balance for those who train (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 improves recovery after exercise

The ratio between the level of testosterone and cortisol in blood is used as a marker for recovery after exercise. PS was found to significantly improve this ratio, indicating that those who consume PS have better recovery capabilities after exercise compared to those who do not (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 reduces perceived muscle soreness

In a double blind, placebo-controlled study, people taking PS reported that their muscle soreness was reduced (Kingsley, M. I., Wadsworth, D., Kilduff, L. P., McEneny, J. & Benton, D. Effects of phosphatidylserine on oxidative stress following intermittent running. Medicine and science in sports and exercise 37, 1300-1306 (2005)). While the participants not taking PS still felt muscle soreness 48 hours after the training session, those who took PS were fully recovered within the same time frame, suggesting PS may enhance training routines.

Sport-Icon3 The solution

The minimal dose of PS shown to be effective for athletes is 600 mg/day. Clinical studies with PS show effects as early as after 10 days of daily consumption. The recommended regimen is to take PS together with protein supplements after completion of an exercise session, although intake of PS prior to exercise may also be considered. PS intake is beneficial for individuals involved in all types of exercise regimens, with clinical studies showing positive effects from PS taken following sports such as models of cycling (or spinning), running, soccer, weightlifting, and more (Fahey, T. D. & Pearl, M. S. The Hormonal and Perceptive effects of phosphatidylserine administrtion during two weeks of resistive exercise induced overtraining.
