HelloPharmacist Scorecard of Ultimate PC+ Phosphatidyl Choline Liver & Brain Granules by ProCaps 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.

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 5 of its 5 active ingredients.
  • “Soy Lecithin Granules” is listed as a grouped ingredient — the label gives one combined amount (2.50 Gram(s)) without saying how much of each component you get.

This product contains 5 active ingredients, all phospholipids—compounds found naturally in cell membranes and brain tissue. Choline is a building block your brain uses for memory and nerve function.

Phosphatidylcholine makes up 40% of the formula and is a major form of choline in the brain. The other three components—phosphatidyl ethanolamine (16%), phosphatidyl inositol (11%), and phosphatidyl serine (1%)—are related compounds with similar roles in brain and liver cell health.

The powder also contains silicon dioxide as an inactive ingredient.

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: Liver and brain health support.
  • We looked for evidence on: Age-related cognitive decline, Alcohol-related liver disease, Alzheimer disease, Cognitive function, Dementia, Fatty deposits — and 4 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: Choline is rated "Insufficient Reliable Evidence To Rate" for Age-related cognitive decline, Alzheimer disease, Cognitive function, Dementia, and more.

The evidence for what this product actually does is mixed and mostly limited. Phosphatidylserine shows possibly effective evidence for age-related thinking decline and Alzheimer disease, but for the other ingredients, we don't have enough reliable data in our files to rate them.

Choline's effectiveness for athletic performance, bronchitis, cognitive aging, fatty liver from nutrition support, hay fever, and Alzheimer disease all falls into the insufficient evidence category—which means the science isn't there yet to say one way or the other. Phosphatidylcholine shows possibly effective evidence only for ulcerative colitis, not for the liver or brain conditions this product's name suggests.

The evidence, ingredient by ingredient Lecithin Choline 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 3 of the 3 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 3 of 3.
  • General safety write-ups exist for 3 of 3.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Overall, the ingredients in this product are generally well tolerated when used as directed. The main side effect to watch for is gastrointestinal upset—bloating, nausea, diarrhea, or altered taste—especially at high doses.

Choline can cause a fishy body odor at high intakes, and at very large doses (9 grams daily or more) may trigger diarrhea, vomiting, and sweating. Phosphatidylserine carries a caution flag: there isn't enough safety data in pregnancy, so the data advises against use during pregnancy.

The same goes for breastfeeding—safety data is insufficient. Choline itself is considered likely safe in pregnancy and is actually needed at higher levels, but prenatal supplement doses should be guided by your doctor.

Breastfeeding demands higher choline, but again, supplements should be used only under professional guidance.

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?
  • 2 of the 3 matched ingredients can interact with medications — Choline, 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 start, double-check with your pharmacist if you're on anticholinergic drugs like atropine, benztropine, or scopolamine—phosphatidylserine in this product may weaken their effects (moderate concern). Also check if you take cholinergic drugs such as bethanechol or pilocarpine, as additive effects are theoretically possible (moderate concern).

If you take atropine, there's a minor risk that choline could reduce its brain effects. For any other prescription medications, use the search tool below to verify—we could not check three of the ingredients for interactions.

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 help with age-related thinking decline or Alzheimer disease if the phosphatidylserine evidence matters to you, but the rest of its brain and liver claims lack solid evidence. If you take anticholinergic medications or cholinergic drugs, you need to check this product with your pharmacist first—the interaction is real, though not huge.

Pregnant or breastfeeding? Talk to your doctor before starting, especially because phosphatidylserine safety isn't established in those situations.

UNSURPASSED. Purity. Quality. Integrity. Effectiveness. Andrew Lessman Founder of ProCaps Labs

Andrew Lessman’s Ultimate PC+ Liver and Brain Granules provides a unique ultraconcentrated source of four essential phospholipids with exceptionally high levels of Phosphatidyl Choline (PC), which is the most abundant and important phospholipid in the body – particularly in the liver and brain. Phospholipids are vital to the structure of all cell membranes, and Phosphatidyl Choline is an essential building block of both liver and brain cells. The U.S. Food and Drug Administration now recognizes Choline as essential because its content in our diet is inadequate and Choline plays such a vital role in so many processes throughout the body, including the liver, nervous and cardiovascular systems, as well as the integrity of all cell membranes, the metabolism of fat and the growth of healthy hair. PC is a necessary raw material for the production of two vital components of the nervous system, acetylcholine, which is the primary neurotransmitter that allows all our nerve cells to communicate, as well as sphingomyelin, which forms the sheath that protects nerve cells. Both are absolutely essential for the normal, healthy functioning of the nervous system and brain – particularly as we age. In addition to providing extremely high levels of Phosphatidyl Choline (1,000 mg per tsp), our special PC+ Granules also provide almost 700 mg of Phosphatidyl Inositol (PI) and Phosphatidyl Ethanolamine (PE), as well as 25 mg of all-important Phosphatidyl Serine (PS). PC and PS are the most concentrated and critical phospholipids in the brain and both have been observed to help with the mild memory problems associated with the normal aging process. PS also supports our body’s healthy response to stress while supporting mental clarity, memory and cognitive function. The liver is perhaps the hardest working organ in our body and is comprised of more than 355,000 square feet of membrane surface area. PC makes up almost two-thirds of the more than 8 acres (about 8 football fields) of that hard-working membrane surface area within the liver. PC is essential to the liver’s vital role of cleansing the body’s internal environment and processing waste products, including virtually all medicines and alcohol. It is also required for the transport and metabolism of fat, protein and cholesterol within the body. PC is absolutely unique in its predominance in both the brain and liver, as well as the critical role it plays in the healthy function of these two vital organs. Given our concerns about fat and cholesterol metabolism, along with our society’s increasing consumption of medicines and alcohol, PC and PS just make sense and our new Ultimate PC+ is our most concentrated, comprehensive and economical way of delivering these essential nutrients.

Ultimate PC+ Phosphatidyl Choline Liver & Brain Granules by ProCaps Laboratories: Common Questions

Does Ultimate PC+ Phosphatidyl Choline Liver & Brain Granules by ProCaps Laboratories interact with any medications?
Yes. Based on its ingredients, Ultimate PC+ Phosphatidyl Choline Liver & Brain Granules 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?
Ultimate PC+ Phosphatidyl Choline Liver & Brain Granules 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.
Can I take this if I'm pregnant?
Choline is actually important in pregnancy, but phosphatidylserine—one of this product's ingredients—doesn't have enough safety data, and the facts advise against it during pregnancy. Talk with your doctor or pharmacist before starting; they can tell you what's right for you individually.
What does phosphatidylserine actually do?
It's a building block in your brain and nerve cells. The evidence suggests it may help with age-related thinking decline and Alzheimer disease, but for other uses this product makes, we don't have reliable data backing it up.
Can this cause side effects?
Most common are digestive—bloating, nausea, diarrhea, or changed taste. Choline can cause a fishy body odor. These happen more at high doses, but phosphatidylserine can trigger insomnia, headache, or stomach upset even at moderate amounts.
Why can't you check three of the ingredients for drug interactions?
Phosphatidyl ethanolamine, phosphatidyl inositol, and the soy lecithin component—we don't have monographs or interaction data on file for them. That doesn't mean they're safe; it just means the data isn't available to us. Your pharmacist can help you investigate further if you're concerned.
Is this safe if I'm breastfeeding?
While choline is actually needed at higher levels during breastfeeding, the supplement safety data for phosphatidylserine isn't there, and there's not enough reliable data for phosphatidylcholine either. Talk with your healthcare provider about whether this product is right for you while nursing.
