This is a phosphatidylserine supplement providing 100 mg per capsule. Each bottle contains 60 capsules. It is a non-stimulant format that can be layered into an existing routine.
The active ingredient is phosphatidylserine, a phospholipid, supplied here as an isolate. The phosphatidylserine source (Iso-Phos) is derived from soy but contains no soy protein.
Take 1 capsule two to three times daily, as Thorne directs, with food. A common pattern is 1 with breakfast, 1 with lunch, and a third with dinner. Take earlier in the day if you are sensitive to alerting effects.
If you take medication that affects acetylcholine signaling, are pregnant or breastfeeding, or have a known soy allergy, talk to your clinician before starting and review the warnings below.
