HelloPharmacist Scorecard of PC Complex by Core Med Science

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

Low disclosure
Ingredient Transparency · database check
Low

Most active ingredients don't disclose an individual amount — you can't tell how much of each you're getting.

Why this rating?
  • The label discloses an exact amount for 0 of its 5 active ingredients.
  • “Phospholipid Complex” is a proprietary blend — the label gives one combined amount (5,200 mg) without saying how much of each component you get.

PC Complex is a liquid supplement with 5 active ingredients. The main ones are sunflower oil and phosphatidylcholine — the latter is a natural compound found in all your cells that plays a role in cell structure and brain function.

The product also contains a phospholipid complex (a blend of similar fat-soluble compounds) and two other phospholipids called phosphatidylethanolamine and phosphatidylinositol. There are no inactive fillers or other ingredients listed.

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: phospholipids for cells and brain support.
  • We looked for evidence on: Alzheimer disease, Dementia, Memory, Nonalcoholic fatty liver disease (NAFLD), Ulcerative colitis, Cognitive decline — and 2 related terms.
  • The strongest evidence on file: Phosphatidylcholine is rated "Possibly Effective" for Ulcerative colitis (Natural Medicines).
  • Also on file: Phosphatidylcholine is rated "Insufficient Reliable Evidence To Rate" for Alzheimer disease, Memory, Dementia, Nonalcoholic fatty liver disease (NAFLD).

Sunflower oil is possibly effective for lowering cholesterol and supporting heart health. Phosphatidylcholine is possibly effective for ulcerative colitis; for other conditions in this product — fatty liver disease, alcohol-related liver damage, Alzheimer's disease, and anxiety — the evidence we hold is insufficient to rate it.

The effectiveness of phosphatidylethanolamine, phosphatidylinositol, and minor glycolipids is not established in our data.

The evidence, ingredient by ingredient Sunflower Oil Phosphatidylcholine

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.

Sunflower oil is generally well tolerated in normal dietary amounts; if you're using it as a concentrated supplement, talk with your doctor first. A small number of people sensitive to plants in the ragweed family (like daisies and chrysanthemums) may have an allergic reaction, though sunflower oil's protein content is very low.

Phosphatidylcholine is generally well tolerated, but high doses may cause digestive upset, bloating, diarrhea, nausea, or altered taste. When taken orally it can also increase sweating or itching in some people.

For pregnancy, sunflower oil is rated likely safe. Phosphatidylcholine data on supplement use in pregnancy beyond food sources is not well studied — talk with your doctor before taking it while pregnant.

We don't have reliable data on either ingredient's use while breastfeeding; check with your healthcare provider first.

Side effects, ingredient by ingredient Sunflower Oil Phosphatidylcholine

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 — Sunflower Oil.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: diabetes medications.
  • For scale: 86 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 using this product if you take antidiabetes drugs (blood sugar medications) — sunflower oil may decrease their effectiveness and raise fasting blood glucose levels, possibly requiring a dose adjustment.

The bottom line

Scorecard at a glanceFormula with limited ingredient disclosure with some supporting evidence for its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

PC Complex may help with cholesterol and heart health through its sunflower oil, though evidence for some of its other uses is still uncertain. The key concern is people taking blood sugar medications — this product may weaken their effect.

If that applies to you, or you take any regular medication, talk it over with your doctor or pharmacist before starting.

PC Complex by Core Med Science: Common Questions

Does PC Complex by Core Med Science interact with any medications?
Yes. Based on its ingredients, PC Complex has a known interaction with 86 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
PC Complex contains 5 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 have type 2 diabetes?
Not without checking with your doctor first. Sunflower oil in this product can raise fasting blood glucose levels and may weaken how well your diabetes medications work, so you and your doctor may need to adjust your treatment plan before you start.
What's phosphatidylcholine, and what does it do?
It's a natural fat-soluble compound present in all your cells that supports cell structure and brain function. This product uses it because there's evidence it may help with ulcerative colitis, though we don't have solid data yet for some other uses it's marketed for.
Are there any common side effects?
Phosphatidylcholine can cause bloating, diarrhea, nausea, altered taste, or increased sweating in some people, especially at higher doses. Start with the recommended dose and talk to your pharmacist if you notice any stomach upset.
Is this safe to use while I'm pregnant?
Sunflower oil is likely safe in pregnancy. We don't have enough reliable data on phosphatidylcholine supplements beyond food sources during pregnancy — talk with your doctor before using this product if you're expecting.
Can I take this while breastfeeding?
We don't have reliable data on supplement use of these ingredients while breastfeeding. Check with your healthcare provider to see if it's right for you.
Does this product have any fillers or other ingredients?
No — the label lists only the active ingredients and no other inactive fillers or additives.
