HelloPharmacist Scorecard of Phosphatidyl Serine by Progressive Professional from Progressive Laboratories

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 product contains one active ingredient: phosphatidylserine, a naturally occurring compound found in cell membranes, particularly in the brain. Phosphatidylserine is thought to support brain cell function and communication.

The capsule also contains inactive ingredients — microcrystalline cellulose, hydroxypropyl methylcellulose, rice flour, L-leucine, and silica — which serve as fillers, binders, and flow agents.

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 cognitive support in elderly.
  • We looked for evidence on: Age-related cognitive decline, Alzheimer disease, Dementia, Cognitive function, cognitive dysfunction.
  • The strongest evidence on file: Phosphatidylserine is rated "Possibly Effective" for Age-related cognitive decline (Natural Medicines).
  • Also on file: Phosphatidylserine is rated "Possibly Effective" for Alzheimer disease.
  • Also on file: Phosphatidylserine is rated "Insufficient Reliable Evidence To Rate" for Cognitive function, Dementia.

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), cognitive function in general, and dementia, the evidence is insufficient to establish how well it works.

If you're considering it for one of these conditions, talk with your doctor about whether the current evidence supports its use in your particular 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 when taken by mouth. The most common side effects reported in studies are flatulence, gastrointestinal upset, headache, insomnia, and nausea.

Insomnia is more likely at higher doses (around 600 mg), and gastrointestinal upset can occur at doses of 200–300 mg per day. Long-term safety hasn't been fully established.

The safety data advises against use during pregnancy and breastfeeding, as there isn't enough information to know it's safe in these situations. If you're pregnant, planning to become pregnant, or breastfeeding, talk with your doctor or pharmacist before taking this supplement.

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 product, double-check with your doctor or pharmacist if you take anticholinergic drugs (such as medications for overactive bladder or certain eye conditions) or cholinergic drugs (such as some Alzheimer disease treatments). Both interact at a Moderate level.

No other medication interactions are documented for the ingredients we hold data on.

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.

Phosphatidylserine may be worth considering if you're interested in supporting cognitive health in age-related decline or Alzheimer disease, though the evidence is still developing. If you take anticholinergic or cholinergic medications, you'll want to check with your doctor or pharmacist first — this product could theoretically change how those drugs work.

Avoid it in pregnancy and while breastfeeding. Talk it over with your own healthcare provider before starting.
