HelloPharmacist Scorecard of PS100 100 mg by Jarrow Formulas
Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.
What’s inside
Full disclosure
PS100 contains one active ingredient: phosphatidylserine 100 mg per softgel capsule. Phosphatidylserine is a naturally occurring compound found in cell membranes; the version in this product is derived from soy.
The capsule also contains inactive ingredients including medium chain triglyceride, bovine gelatin, glycerin, water, sunflower lecithin, silicon dioxide, mixed tocopherols, and ascorbyl palmitate — these are excipients that help deliver and preserve the active ingredient.
Does it work?
Moderate evidence
Phosphatidylserine is rated possibly effective for age-related cognitive decline and Alzheimer disease based on available evidence. For athletic performance, attention deficit-hyperactivity disorder (ADHD), general cognitive function, and dementia, the evidence isn't established — we don't have enough reliable data to know whether it works for those uses.
How safe is it?
Well-documented data
Phosphatidylserine is generally well tolerated in studies, though long-term safety isn't fully established. The most common side effects reported orally are flatulence, gastrointestinal upset, headache, insomnia, and nausea.
Gastrointestinal upset can occur at doses of 200–300 mg/day, and insomnia is more likely at higher doses around 600 mg. There isn't enough safety information to recommend use during pregnancy, so it's best to avoid it.
Safety while breastfeeding is also unknown, so avoidance is recommended. If you're pregnant, planning pregnancy, or breastfeeding, talk with your pharmacist or doctor before taking this product.
Meds to double-check
Moderate interaction found
Before you start PS100, double-check any anticholinergic drugs you take — these manage conditions like overactive bladder, muscle spasms, and certain types of poisoning, and phosphatidylserine may reduce their effectiveness (Moderate). Also confirm any cholinergic drugs — used for myasthenia gravis, Alzheimer disease, and glaucoma — as additive effects are possible (Moderate).
Use the medication checker on this page with your exact prescriptions.
The bottom line
Scorecard at a glanceFully disclosed formula with some supporting evidence for its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.
PS100 may be worth considering if you're concerned about age-related memory loss or early Alzheimer disease, though the evidence is moderate. If you take anticholinergic or cholinergic medications, check with your pharmacist first — this supplement could interfere with how they work.
Pregnant or breastfeeding? Skip it and ask your doctor or pharmacist for alternatives.

PS100 100 mg by Jarrow Formulas Drug Interactions
HelloPharmacist Interaction Report
PS100 by Jarrow Formulas contains phosphatidylserine, which does interact with certain medications.
The most serious concern is with anticholinergic drugs — medications that block a nerve chemical called acetylcholine. Phosphatidylserine is thought to increase acetylcholine levels, which could theoretically reduce how well these drugs work.
This is a Moderate-severity interaction.
Read the full breakdown — every affected drug type, severity by severity
Phosphatidylserine may also have additive effects with cholinergic drugs (Moderate severity) — medications that work by boosting acetylcholine. When combined, you might experience stronger cholinergic effects than expected.
Although we've checked phosphatidylserine, the interaction data we hold covers only these two drug categories. If you take an anticholinergic or cholinergic medication, use the drug checker on this page to confirm your specific prescriptions before you start.
Altogether, these interactions span 218 individual medications.
