HelloPharmacist Scorecard of Phosphatidylserine Complex by Solgar

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

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 3 of its 3 active ingredients.
  • No proprietary blends here — you can verify the dose of every single component.

This product contains 3 active ingredients. Phosphatidylserine and phosphatidylcholine are both phospholipids — molecules that are structural building blocks of cell membranes, especially in the brain.

Phosphatidylcholine may also help support liver health and digestion. The inactive ingredients are common tablet binders and fillers like microcrystalline cellulose, silica, and magnesium stearate.

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: brain function and memory support.
  • We looked for evidence on: Age-related cognitive decline, Alzheimer disease, Attention deficit-hyperactivity disorder (ADHD), Cognitive function, Dementia, Memory — and 3 related terms.
  • 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: Phosphatidylcholine is rated "Insufficient Reliable Evidence To Rate" for Alzheimer disease, Memory, Dementia, Aging.

Phosphatidylserine shows possibly effective evidence for age-related cognitive decline and Alzheimer's disease. Phosphatidylcholine appears possibly effective for ulcerative colitis.

For other uses listed — athletic performance, ADHD, general cognitive function, dementia, and nonalcoholic fatty liver disease — the evidence we hold is insufficient to rate whether they work. Talk with your doctor about whether this product matches what you're hoping to treat.

The evidence, ingredient by ingredient Phosphatidylcholine 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 2 of the 2 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 2 of 2.
  • General safety write-ups exist for 2 of 2.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Both phosphatidylserine and phosphatidylcholine are generally well tolerated when taken by mouth. Common side effects include mild digestive complaints like bloating, nausea, diarrhea, or flatulence; headache and insomnia are also possible, especially at higher doses of phosphatidylserine.

High doses of phosphatidylcholine (30 grams or more daily) may cause more significant digestive upset. Pregnancy and breastfeeding data are limited.

Phosphatidylserine safety is not established in pregnancy and breastfeeding — the data advises against use until you've talked it over with your doctor. Phosphatidylcholine itself is needed during pregnancy, but supplement safety beyond what you get from food is not well studied — check with your doctor before taking it while pregnant or nursing.

Meds to double-check

Moderate interaction found
Known Interaction Concern · database check
Moderate identified

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

Why this rating?
  • 1 of the 2 matched ingredients 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.

Check with your doctor or pharmacist before taking this product if you use anticholinergic drugs (common in bladder, bowel, allergy, cold, and some psychiatric medications) or cholinergic drugs (used for myasthenia gravis, Alzheimer's disease, and some eye conditions). Both interactions are moderate-severity theoretical concerns based on how the ingredient works in your body.

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.

This product may be worth considering if you're looking for brain support, especially for age-related memory changes or early Alzheimer's concerns. Before you start, check your medications with your doctor or pharmacist — particularly if you take anything for an overactive bladder, Parkinson's disease, myasthenia gravis, or an eye condition.

If you're pregnant or breastfeeding, talk it over with your healthcare provider first.

Formula

Phosphatidylserine is a natural substance found in the brain where it plays an important role in the integrity and fluidity of cell membranes. Phosphatidylserine levels in the brain can decline with age. Supplementing with Phosphatidylserine Complex is a good choice to help replenish phosphatidylserine levels and support a healthy mind.

Phosphatidylserine Complex by Solgar: Common Questions

Does Phosphatidylserine Complex by Solgar interact with any medications?
Yes. Based on its ingredients, Phosphatidylserine Complex 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 Complex contains 3 active ingredients, and an interaction can come from any of them. We check every ingredient, combine the results into one list per medication, and show which ingredient and mechanism is 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.
Can I take this if I'm pregnant or breastfeeding?
Phosphatidylserine isn't safe enough in pregnancy and breastfeeding based on the data we have — talk with your doctor before taking it. Phosphatidylcholine is actually needed during pregnancy, but supplement safety beyond food sources isn't well studied, so check with your healthcare provider about that one too.
What side effects might I experience?
Most common are mild digestive symptoms — bloating, nausea, diarrhea, or flatulence — plus occasional headache or trouble sleeping. High doses of phosphatidylserine (600 mg or more) make insomnia more likely. Digestive upset from phosphatidylcholine is uncommon at usual doses but can happen with very high amounts.
Does this really help with memory or brain fog?
Phosphatidylserine shows possibly effective evidence for age-related memory decline and Alzheimer's disease — so there's a reasonable basis for trying it if that's your concern. For general brain fog or focus, the evidence we hold isn't strong enough to say either way.
Will this work with my anticholinergic or cholinergic medication?
There's a moderate-level theoretical concern — phosphatidylserine may interfere with anticholinergic drugs or add to the effects of cholinergic drugs. It's not proven in humans, but definitely run your specific medications through the search tool on this page or ask your pharmacist before you start.
How long does it take to notice a benefit?
The product facts don't include information about how quickly you might see results. Talk with your doctor about what to expect and how long to try it before deciding if it's helping.
Is this safe for long-term use?
Phosphatidylserine is generally well tolerated in studies, but long-term safety hasn't been fully established in the data we hold. Check with your pharmacist or doctor if you're planning to take it for months or years.
