HelloPharmacist Scorecard of Phosphatidyl Serine 100 mg by NOW
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
This product contains 3 active ingredients. Inositol is a vitamin-like compound thought to help regulate blood sugar and support mood; choline is a nutrient essential for brain and liver function; and phosphatidyl serine is a fat-like substance found in cell membranes, particularly in the brain.
Together they're intended to support cognitive function and cellular health. The capsule also contains inactive ingredients — cellulose powder, cellulose, silica, and magnesium stearate — which are standard binding and flowing agents.
Does it work?
Moderate evidence
Phosphatidyl serine is rated possibly effective for age-related cognitive decline and Alzheimer disease. Inositol is rated possibly effective for polycystic ovary syndrome (PCOS), metabolic syndrome, and preterm labor.
The evidence for choline is less clear — we hold insufficient data to rate it for conditions like Alzheimer disease, age-related cognitive decline, or hay fever. Other uses listed here (athletic performance, anxiety, depression, diabetic neuropathy) are rated possibly ineffective or have insufficient evidence.
How safe is it?
Well-documented data
All three ingredients are generally well tolerated at standard doses. The most common side effects are mild digestive ones: inositol may cause diarrhea, gas, or nausea; choline may cause a fishy body odor and at high doses (above 3.5 grams daily) can trigger nausea, vomiting, and diarrhea; phosphatidyl serine may cause flatulence, gastrointestinal upset, headache, insomnia, or nausea—insomnia is more likely at higher doses around 600 mg.
For pregnancy and breastfeeding: inositol is rated possibly safe but should be used only under medical supervision; choline is rated likely safe and is actually important during pregnancy and breastfeeding, though supplement doses should be advised by your doctor; phosphatidyl serine safety data is insufficient and avoidance is recommended during both pregnancy and breastfeeding. Talk with your doctor or pharmacist about use during pregnancy or while nursing.
Meds to double-check
Moderate interaction found
Check with your doctor or pharmacist before taking this product if you use diabetes medications (inositol may increase low blood sugar risk), anticholinergic drugs (phosphatidyl serine may reduce their effectiveness), or cholinergic drugs (phosphatidyl serine may add to their effects). Also flag any use of atropine, as choline might interfere with it.
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 support cognitive function and brain health, particularly for age-related cognitive decline or Alzheimer disease, though evidence varies by ingredient. It's not for you if you take diabetes medications, anticholinergic drugs, or cholinergic agents without first checking with your doctor or pharmacist.
Side effects are usually mild and digestive. Run your exact medications through the checker on this page and discuss this supplement with your own healthcare provider before starting.

Phosphatidyl Serine 100 mg by NOW Drug Interactions
HelloPharmacist Interaction Report
NOW's Phosphatidyl Serine 100 mg can interact with several medication types through its inositol, choline, and phosphatidyl serine content.
The most serious concern is a Moderate interaction: inositol may increase the risk of low blood sugar (hypoglycemia) when taken with diabetes medications, since inositol itself lowers blood glucose levels.
Read the full breakdown — every affected drug type, severity by severity
Phosphatidyl serine poses two additional Moderate interactions. It may decrease the effectiveness of anticholinergic drugs (medications that block acetylcholine activity in the brain and body) by raising acetylcholine levels.
It may also have additive effects with cholinergic drugs (medications that increase acetylcholine), which could strengthen cholinergic side effects.
Choline carries a Minor interaction with atropine, a specific anticholinergic drug used for certain medical conditions — theoretically it might reduce atropine's effects in the brain.
Altogether, these interactions span 305 individual medications. Use the medication checker below to see if any of yours are affected, and talk with your doctor or pharmacist before starting this product if you take diabetes medications, anticholinergic drugs, or cholinergic agents.

For each ingredient in Phosphatidyl Serine 100 mg with known interactions, here are the types of medications they can affect. Open any type for the detail — or search your exact drug in the checker above.
Phosphatidyl Serine
Anticholinergic Drugs
Theoretically, phosphatidylserine might decrease the effectiveness anticholinergic drugs.
Phosphatidylserine is thought to increase acetylcholine levels, which could theoretically interfere with the activity of anticholinergic agents.
Cholinergic Drugs
Theoretically, phosphatidylserine might have additive effects with cholinergic drugs.
Phosphatidylserine is thought to increase acetylcholine levels, which could theoretically lead to additive cholinergic effects when used with cholinergic drugs.
Inositol
Antidiabetes Drugs
Theoretically, taking inositol with antidiabetes drugs might increase the risk of hypoglycemia.
Clinical research shows that inositol lowers blood glucose levels and glycated hemoglobin (HbA1c) levels in patients with diabetes.
Choline
Atropine
Theoretically, choline might decrease the effects of atropine in the brain.
Animal research shows that administering choline one hour before administering atropine can attenuate atropine-induced decreases in brain levels of acetylcholine. Theoretically, concomitant use of choline and atropine may decrease the effects of atropine.
