HelloPharmacist Scorecard of Phosphatidylserine by Ortho Molecular Products

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.

From our pharmacy team — supplement deep dive

Generated from HelloPharmacist’s pharmacist-curated databases and editorial rules · Last generated Sep 3, 2026

What’s inside

Full disclosure
Ingredient Transparency · database check
Full

Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 1 of its 1 active ingredient.
  • No proprietary blends here — you can verify the dose of every single component.

This supplement contains one active ingredient: phosphatidylserine. It's a naturally occurring compound that plays a role in cell membranes and is thought to support brain function.

The other ingredients are inactive — sunflower phosphatide complex, gelatin, glycerin, polyglycitol syrup, and purified water — they serve as the capsule and delivery system.

Does it work?

Moderate evidence
Evidence for Intended Use · database check
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed

This product doesn't appear to be marketed for a specific use, so we graded Phosphatidylserine's overall clinical evidence instead.

Moderate

Some clinical evidence supports Phosphatidylserine for:

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.
  • Since the label doesn't commit to one use, we graded the ingredient's overall clinical evidence instead.
  • On file: Age-related cognitive decline — rated "Possibly Effective" (Natural Medicines).
  • On file: Alzheimer disease — rated "Possibly Effective" (Natural Medicines).

Phosphatidylserine is possibly effective for age-related cognitive decline and Alzheimer disease based on available research. For athletic performance, ADHD, general cognitive function, and dementia, the evidence is too weak or limited for us to rate it reliably.

If you're considering this for a specific concern, talk it over with your doctor — they can tell you whether the current evidence supports its use for your situation.

The evidence, ingredient by ingredient Phosphatidylserine

How safe is it?

Well-documented data
Safety Information · database check
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

Why this rating?
  • We hold adverse-effect (side-effect) data for 1 of the 1 matched ingredient.
  • Pregnancy & breastfeeding safety ratings cover 1 of 1.
  • General safety write-ups exist for 1 of 1.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Phosphatidylserine is generally well tolerated in studies, though long-term safety hasn't been fully established. The most common side effects are flatulence, gastrointestinal upset, headache, insomnia, and nausea.

Higher doses (600 mg or more) are more likely to cause insomnia, and doses of 200–300 mg daily can trigger stomach upset. There isn't enough safety information during pregnancy, so it's best to avoid it then.

Safety while breastfeeding is also unknown — avoidance is recommended.

Known Interaction Concern · database check

The most serious documented interaction for these ingredients is Moderate. Check your medications for a personalized result.

Why this rating?
  • 1 of the 1 matched ingredient can interact with medications — Phosphatidylserine.
  • The most serious interaction on file is rated Moderate.
  • For scale: 219 individual medications appear in the full list. A big number alone doesn't make a product dangerous — what matters is whether YOUR medication is on it, so run yours through the interaction checker on this page.

Before taking this supplement, check whether you use anticholinergic drugs (used for overactive bladder, motion sickness, or certain other conditions) or cholinergic drugs (used for myasthenia gravis, Alzheimer disease, or other conditions). Both carry Moderate-severity theoretical concerns.

The bottom line

Scorecard at a glanceFully disclosed formula with some supporting evidence behind its ingredients' uses. Moderate medication interactions have been identified, and safety information is well characterized.

Phosphatidylserine may help with age-related memory decline and Alzheimer disease, though the evidence is moderate. If you take anticholinergic or cholinergic medications, check with your doctor or pharmacist before starting — the theoretical interaction could affect how well your drugs work.

Expect possible stomach upset or sleep trouble, especially at higher doses. It's not recommended in pregnancy or while breastfeeding.

Phosphatidylserine by Ortho Molecular Products: Common Questions

Does Phosphatidylserine by Ortho Molecular Products interact with any medications?
Yes. Based on its ingredients, Phosphatidylserine has a known interaction with 219 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Phosphatidylserine contains a single active ingredient, and that one ingredient can interact with many different medications on its own. We check it against each medication and show the mechanism responsible.
Where does this information come from?
The product label data comes from the NIH Dietary Supplement Label Database (DSLD); the interaction data is built on the Natural Medicines database and reviewed by HelloPharmacist pharmacists.
What does phosphatidylserine actually do?
It's a compound found in cell membranes that's thought to support brain function and memory. Research suggests it may help with age-related memory problems and Alzheimer disease, though the evidence is still building.
Can I take this if I'm pregnant or breastfeeding?
No — there isn't enough safety data. Pregnancy is rated unsafe, and breastfeeding safety is unknown, so avoidance is recommended. Talk with your doctor if you're pregnant or nursing and want to discuss options.
What side effects should I watch for?
The most common ones are flatulence, stomach upset, headache, insomnia, and nausea. Higher doses (600 mg or more) are more likely to cause sleep trouble, and 200–300 mg daily can trigger stomach issues. Start with a lower dose if you're sensitive to GI effects.
Is this proven to improve memory in healthy people?
Not reliably — we don't have strong enough evidence to rate it for general memory support, ADHD, or athletic performance in people without age-related decline or Alzheimer disease.
How long does it take to notice a benefit?
The facts on file don't specify how quickly phosphatidylserine works. Your doctor or pharmacist can give you a better sense of what to expect based on your specific situation.
