What is the primary biologic role of Phosphatidylserine in CCDS supplements?

• A. Promotion of neurotransmitter release
• B. Antioxidant activity
• C. Inhibition of inflammatory cytokines
• D. Maintenance of cell membranes and facilitation of neuronal processes

Answer: (D)

Phosphatidylserine is a structural phospholipid that helps maintain the integrity and fluidity of cell membranes, with a special emphasis in neuronal membranes. This membrane stability underpins many neuron's essential functions, including the proper docking and function of receptors, ion channels, and the machinery that drives synaptic vesicle fusion and neurotransmitter signaling. In this way, phosphatidylserine supports overall neuronal processes by keeping membranes healthy and responsive, which is why it’s described as having a primary role in maintaining cell membranes and facilitating neuronal activity.

The other options describe effects that aren’t the core function of phosphatidylserine in this context: it isn’t primarily an antioxidant, it doesn’t directly inhibit inflammatory cytokines as its main action, and while it can influence signaling pathways, the fundamental role is membrane maintenance that enables neuronal processes.
