What is Phosphatidylserine?

Phosphatidylserine is a Lipid supplement available in 1 form.

Not all forms of Phosphatidylserine are equal. The form you choose determines how much Phosphatidylserine actually reaches your tissues, and the difference between the best and worst forms can be substantial. Soy-derived phosphatidylserine is the most clinically researched phospholipid for cognitive applications, with FDA-qualified health claim status for its relationship to cognitive function. As an S1-tier compound, research demonstrates that soy-sourced phosphatidylserine supports healthy cortisol response, memory recall, and neuronal membrane fluidity.

Forms of Phosphatidylserine Compared

Phosphatidylserine Preferred (Preferred Form) has a bioavailability rating of high (S1 — best tier). Typical dose range: not yet documented in our database.

What the Research Shows

Phosphatidylserine (PS) is a phospholipid concentrated in brain cell membranes, essential for neurotransmitter release and synaptic function. Clinical trials demonstrate benefits for memory, attention, and cortisol management during stress. The FDA permits a qualified health claim linking PS to reduced risk of cognitive decline. Soy-derived PS provides identical molecular structure to endogenous PS.

How to Choose the Right Form

Phosphatidylserine is classified as Preferred Form by FormulaForge — our top recommendation for Phosphatidylserine. It carries a bioavailability rating of high (S1 — best tier), meaning more of the active compound reaches your tissues per dose unit compared to lower-rated forms.
