Phosphatidylserine (PS) is present in every cell membrane from the brain and nervous system to hormone function and the adrenal glands. Here are the primary scientifically backed reasons why anyone – from professional athletes to weekend warriors should add PS from iStressedOut to their health, wellness and recovery regimen.
- Reduces the tissue breakdown that accompanies overtraining and / or overstretching.[i] PS reduces muscle soreness after exercise.[ii]
- Intensely trained athletes found that 800 mg of PS taken daily reduced the cortisol rise by 20% as compared with placebo.[iii]
- Cyclists who took PS found that they could relieve overtraining symptoms, including muscle soreness. [iv] [v] [vi]
- PS improves exercise capacity during high intensity training and will increase performance during intermittent running.[vii]
- Nonathletic males found that daily doses of 400 and 800 mg of PS reduced cortisol levels after exercise by 16% and 30%.[viii]
- PS relieves overtraining symptoms, including muscle soreness due to cortisol.[ix] [x] [xi] [xii] [xiii]
- PS helps insomnia and sleep disorders caused by excess cortisol at the end of the day. [xiv]
- PS raises lowT by increasing the testosterone cortisol ratio. [xv]
PS is an essential sports recovery supplement for
the serious professional athlete and
athletes of all ages and ability.
Chewing 2 iStressedOut tabs after every workout is
the essential recovery advantage!
