After Glow and Phosphatidylserine

You have to ask yourself the question-what holds you back from getting those extra reps on your last set of the workout? It could be a number of things, but you have to think of the internal hormone levels a huge factor in preventing muscle growth and limiting performance.


BioRhythm thought of this with AfterGlow. By adding an ingredientcalled phosphatidylserine, AfterGlow now has the ability to affect hormone levels that impact the bottom line-muscle growth!

Phosphatidylserine is an important phospholipid membrane component which plays a key role in cell cycle signaling. Most importantly it has been shown to affect cortisol (stress hormone), lactate (lactic acid), growth hormone, as well as testosterone levels. Studies have shown that those who consume phosphatidylserine before, during , or post workout have a reduction in cortisol levels, reduce lactate build up, in turn this allows for more growth hormone to be released in the body.
