      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.

      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.

      Pros

      Can't say. Did not take long enough.

      Cons

      Causes me gastro-intestinal distress issues.
