Who doesn't want to improve their cognitive health? Ok. Ok. this is not the limitless pill, I'm sure that would cost a lot more ;) Taking this is a nudge in the right direction. I'd recommend you take it regularly, you may catch yourself with less "tip of your tough" moments. Using with MCT oil helps too.

Supplement of the gods. Go ahead and read up on it.

They should put this stuff in the water reservoir. Very welcome side-effects in larger quantities.


I bought this brand ( Now ) when a local health food store was running a %30 off sale on Now products. It's fairly expensive and didn't seem to work for me at first. I was just taking 1 - 100 mg capsule with my other vitamin supplements. After reading up on Phosphatidyl Serine and its effect on cortisol I learned that you really need to take 300 mg. and that taking a few hours before bed is one of the best times to take it. I would have liked to have known this earlier. The Now label says to take " 1 capsule up to 3 times daily, preferably with food." I was never sure I even felt anything until I started taking 3 - 100 mg. capsules an hour or so before going to bed and long after eating. When I started making this product into my nightcap I was surprised -- it really does work - mostly by giving you a mellow, warm feeling of letting go of stresses. Multiple times during the day may be better but this product isn't cheap. I've long felt that I have adrenal fatigue. I have tried all kinds of adaptogens as well as cutting back on caffeine, eating a low carb, good protein and fresh produce. I would rate it even higher if it were cheaper and it they had labelled the product better. The label recommends combining P Serine with Now DMAE and Super Cortisol Support.
