Answer: Phosphatidylserine is a phospholipid that forms part of every neuron's membrane, where signals are sent and received. Trials in older adults with memory complaints report modest improvements in recall at 100 to 300 mg a day over twelve weeks. It is well tolerated, and modern supplements source it from sunflower or soy.
- A structural fat in brain-cell membranes; levels decline with age.
- Trials: modest recall gains in older adults with memory complaints.
- Dose 100 to 300 mg daily, judged over 12 weeks.
- Plant-sourced today; the old cow-brain version is gone.
What phosphatidylserine is
Cell membranes are made of phospholipids, and phosphatidylserine, usually shortened to PS, is the one concentrated on the inner face of neuron membranes. It anchors the proteins that release and receive neurotransmitters and it flags cells for clean-up when they are damaged. The brain holds more PS than any other organ, and its content falls with age.
What the trials show
Early studies in the 1990s used PS from bovine brain and found improvements in memory tests in older adults with age-related complaints. After mad cow disease, supply switched to soy and later sunflower lecithin, and trials with the plant form, at 100 to 300 mg a day for twelve weeks, again report modest gains in delayed recall and learning. Reviews on PubMed rate the effect as small but consistent in that group, and unproven in young healthy adults.
Who it seems to help
| Group | Finding |
|---|---|
| Older adults with memory complaints | Modest recall improvement |
| Healthy young adults | Little measurable change |
| Athletes under stress | Some reduction in cortisol response |
| Diagnosed dementia | Not a treatment; results inconsistent |
The pattern fits its role as a structural nutrient: it helps most where the structure is wearing.
Dose, source and safety
Studies use 100 mg up to three times daily. PS is fat-soluble, so it absorbs best with a meal. Side effects are rare; insomnia and stomach upset have been reported above 300 mg. Sunflower-derived PS avoids soy allergy concerns. The FDA permits a qualified health claim for PS and cognitive dysfunction in the elderly, unusual for a supplement ingredient, while noting the evidence is limited.
How PS is used in NeuroRecall
PS sits on the memory track of NeuroRecall's formula alongside Bacopa, supporting the membranes that connections are built into. The per-capsule amount and the plant source are on your bottle's panel. Take the capsule with breakfast so the fat-soluble ingredients absorb. Pack options and the NeuroRecall sale are on the NeuroRecall official website.
What to expect
Nothing quickly. Like Bacopa, PS works on structure, so the trial window is twelve weeks. Keep a weekly note of how easily names and lists come back. And keep the fundamentals in place: the NIA points out that sleep and exercise change the same structures PS supports.
Read the cautions, then the price
Ginkgo, Rhodiola and Bacopa warnings sit above the NeuroRecall discount on purpose.

Is phosphatidylserine safe?
Well tolerated in trials up to 300 mg daily for months. Take it with food.
Is it from animal brain?
Not any more. Modern PS is made from sunflower or soy lecithin.
Can I take PS with a statin?
There is no known interaction, but tell your doctor about every supplement you take.
