Phosphatidylserine is the most abundant phospholipid in the human brain and is made by the body in small amounts. This important phospholipid supports neuronal cell integrity by providing the building blocks needed for cell membrane structure and function.

Phosphatidylserine has also been documented to increase the availability of choline for synthesis of acetylcholine, an important neurotransmitter involved in memory and learning. It may also help enhance cognitive function by maintaining cholinergic activity in the brain.

Studies show Phosphatidylserine:

  • may aid the slowdown of age related cognitive decline,
  • may help with depression
  • may improve Parkinson’s Disease symptoms
  • may improve ADHD symptoms.
