      PS 100

      from DURHAM NC on 3/12/2020
      Great calming supplement. Helpful to take in the evening along with magnesium chloride foot bath to promote good sleep. I like that it's made from sunflower instead of soy.

      Helps lower cortisol

      from Florida on 1/05/2018
      This PS 100 mg by Jarrow Formulas is effective in lowering cortisol. Just play with the dosage. I take one before cortisol rises at lunch time it helps.



      It's expensive

      Digestive distress

      from Northern VA on 7/14/2017
      I have been using PS 100 mg by Jarrow Formulas for about a week and it is causing me to have gastro-intestinal distress. I had used Phosphatidyl Serine 100 mg from a different brand and it did not cause any digestive tract problems. It was derived from soy. This Jarrow product is derived from sunflowers so perhaps that is the difference, but I have eaten sunflower seeds in the past with no ill effects. Perhaps this is derived from a different part of the plant. It caused me to have stomach cramps and diahhrea. Jarrow carries a soy derived product, but it required and ice pack to ship which would have cost me $24.99, so I opted for this version.


      Can't say. Did not take long enough.


      Causes me gastro-intestinal distress issues.

      part of the plan

      from Rockville, MD on 11/11/2013
      Our nutritionist prescribed PS 100 mg as part of a nutrition plan for our 10 yr old son with language and working memory issues. Were seeing some improvement and hope to see more over time.



      pricey when you have to order the cooler & ice packs for shipping
