Phosphatidylserine Normalizes Cortisol Levels in Athletes
Inhibits Exercise-Induced Increase in Cortisol Levels
Several double-blind, placebo-controlled clinical trials show how phosphatidylserine in Flavay Plus® can prevent and improve exercise-induced cortisol levels and other markers related to hard training.
A double-blind, placebo-controlled study at California State University investigated the effects of phosphatidylserine in Flavay Plus® on hormone levels, muscle soreness and feelings of well-being in experienced weight-trained athletes. The program was designed to over-train the athletes. Subjects were instructed to train as hard as possible four days a week each during a two-week training period, and to use as much weight as possible for each exercise. After a three-week washout phase, the same athletes switched treatments and repeated the workout program for another two weeks.
Subjective perception of well-being and muscle soreness (considered the most reliable markers of over-training) were analyzed. The athletes had considerably less muscle soreness when taking phosphatidylserine in Flavay Plus® than when taking the placebo.
Athlete's perception of well-being results in a profound influence in competitive spirit and performance. Subjects taking phosphatidylserine in Flavay Plus® had a measurably better perception of well-being, particularly after the first week of training.
Following intense weight-training, cortisol was noticeably lower in subjects taking phosphatidylserine in Flavay Plus®. (121,144,145)
A double-blind, placebo-controlled study using eight healthy male volunteers (ages 24-42), performed three sessions of bicycle ergometer tests at one-week intervals. As expected, the physical exercise resulted in a significant increase in ACTH and cortisol levels in the placebo group. However, the group that received phosphatidylserine in Flavay Plus® found significant suppression in ACTH and cortisol response to exercise. (134)
A double-blind, placebo-controlled, cross-over study conducted at St. Cloud State University showed that phosphatidylserine in Flavay Plus® significantly lowered creatine kinase (CK) levels 24 hours after exercise. (Creatine kinase is an indicator of skeletal muscle damage after exercise.) After 15 days of taking either phosphatidylserine or a placebo, 12 trained runners performed a 90-minute run. Intense exercise will cause an increase in plasma and serum CK levels. The results showed phosphatidylserine in Flavay Plus® significantly reduced CK levels, an indicator of reduced muscle damage, compared to the placebo. (120,228)
Testosterone, Cortisol and ACTH
Over-training is a natural hazard of competitive sports. During the early stages, your muscles ache, your heart rate and cortisol levels increase, and testosterone levels fall especially in male athletes. Your body can recover after a few days of rest but chronic over-training often causes an unhealthy ratio of the anabolic (muscle-building) hormone, testosterone, to the catabolic (muscle-wasting) hormone, cortisol.
So it's an athlete's challenge to optimize the ratio of steroid hormones testosterone and cortisol. Also adrenocortiocotropic hormones (ACTH), because ACTH levels increase after exercise and that leads to higher cortisol levels. This is why some athletes will use anabolic steroids (testosterone and its precursors) in order to build testosterone and inhibit cortisol levels. But long-term use of anabolic steroids can result in infertility and an increase risk of severe liver tumors, kidney disorders, heart disease and other health problems.
The good news is phosphatidylserine in Flavay Plus® is an effective non-drug and safe alternative in normalizing cortisol levels for athletes. (134)
