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.

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
Moderate

Some clinical evidence supports this product's ingredients for its stated purpose, but it isn't conclusive.

Why this rating?
  • The label markets this product for: memory and concentration support.
  • We looked for evidence on: Age-related cognitive decline, Cognitive function, Attention deficit-hyperactivity disorder (ADHD), mental clarity, focus, brain health.
  • The strongest evidence on file: Phosphatidylserine is rated "Possibly Effective" for Age-related cognitive decline (Natural Medicines).
  • Also on file: Phosphatidylserine is rated "Insufficient Reliable Evidence To Rate" for Attention deficit-hyperactivity disorder (ADHD), Cognitive function.

Phosphatidylserine is possibly effective for age-related cognitive decline and Alzheimer disease. For athletic performance, cognitive function, ADHD, and dementia, the evidence isn't established — we don't have reliable data to say whether it works for those uses.

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 isn't fully established. The most common side effects are flatulence, gastrointestinal upset, headache, insomnia, and nausea.

Insomnia is more likely at higher doses (around 600 mg), and gut upset can happen at doses of 200–300 mg daily. There isn't enough safety data for pregnancy — the facts advise against use during pregnancy.

Safety while breastfeeding is also unknown, so the data advises against it. Talk with your doctor or pharmacist about whether this is right for you if you're pregnant, planning pregnancy, or breastfeeding.

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 you take Phosphatidyl-Serine, check with your doctor or pharmacist if you use anticholinergic drugs (for overactive bladder, nausea, or other conditions) or cholinergic drugs. Both interactions are rated Moderate — phosphatidylserine may reduce how well anticholinergics work or add to the effects of cholinergic medications.

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.

Phosphatidyl-Serine may help with age-related memory decline or Alzheimer disease if you're looking for a possibly effective option. If you take anticholinergic or cholinergic medications, you'll want to clear it with your doctor or pharmacist first because of the theoretical risk it could interfere with them.

It's generally well tolerated but can cause stomach upset or sleep problems, especially at higher doses. Talk it over with your own healthcare provider before starting.
