The bottom line No known interaction

We found no known interaction between Phosphatidylserine and Atorvastatin in our sources. Absence of a documented interaction is not the same as proven safety, and does not guarantee one does not exist. Do not start, stop, or change a medication or supplement based on this page; confirm with your pharmacist or doctor first.

Phosphatidylserine and Atorvastatin

We checked these two against our interaction database. Here is what we found.

No Known Interaction Found

We did not find a documented interaction between Atorvastatin and Phosphatidylserine in our sources. This does not guarantee that the combination is completely free of risk — there is often limited research on supplements and herbal products, especially around drug interactions.

If you decide to take both, the practical routine is simple: add one new thing at a time and note the date you started it. If the combination is going to disagree with you, it usually shows in the first days to a couple of weeks — and a start date turns “I’ve been feeling off” into something a pharmacist can actually work with. Do not stop a prescribed medicine on your own.

Always talk with your pharmacist or doctor before making changes to your medications or supplements, particularly if you take several medications or have an ongoing health condition.

Phosphatidylserine safety at a glance

Phosphatidylserine overall Use caution Generally well tolerated in studies, but long-term safety is not fully established.
Pregnancy Avoid There is not enough safety information, so it is best to avoid use during pregnancy.
Breastfeeding Avoid Safety while breastfeeding is unknown, so avoidance is recommended.

Safety guidance is general; always confirm with your pharmacist or doctor for your situation.

How we checked

Why No Interaction Is Listed for Atorvastatin

Interactions in our licensed database are recorded against drug classes, not just single drug names. Atorvastatin is filed under 7 classifications — including hmg-coa reductase inhibitors ("statins"), organic anion-transporting polypeptide substrates (oatp), glucuronidated drugs. Phosphatidylserine has documented interactions with 2 drug classes — the most serious being anticholinergic drugs (moderate) and cholinergic drugs (moderate) — and none of Atorvastatin’s classifications are among them.

Classification data comes from our licensed Natural Medicines dataset. A medication can belong to classes beyond those recorded there, so this describes how the check was run — it is not a safety guarantee.

What Phosphatidylserine Itself Has Been Linked To

This is not an interaction — nothing below involves Atorvastatin. It is the side-effect record for Phosphatidylserine on its own, from the licensed Natural Medicines monograph. If something new turns up after you add Phosphatidylserine, this list is the first place to look.

See Every Supplement That Interacts With Atorvastatin

This page covers Phosphatidylserine only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Atorvastatin page lists 181 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), Apple (major), Beer (major), Grapefruit (major) and Green Tea (major).

By severity: 9 major · 136 moderate · 36 minor.

From our pharmacist’s overview on the Atorvastatin page

“Grapefruit is the entry to understand first. Atorvastatin (Atorvaliq) is cleared by an enzyme called CYP3A4, and grapefruit blocks that enzyme, letting statin levels climb along with the risk of side effects like muscle pain.”

About Phosphatidylserine

What is Phosphatidylserine?

Phosphatidylserine
  • Memory and cognitive support
  • Age-related cognitive decline
  • Attention and focus (ADHD)
  • Mental performance under stress
  • Exercise recovery

Phosphatidylserine is a natural fat-like compound found in cell membranes, especially in the brain, and it is sold mainly to support memory and thinking. Some research suggests possible benefits for age-related memory problems, but the evidence is limited and far from conclusive. It is generally well tolerated, but check with your pharmacist or doctor before using it, especially during pregnancy or breastfeeding.

Phospholipid derived from soy lecithin, sunflower lecithin, or (historically) bovine brain · Capsules, softgels, tablets, powders

An interaction check asks whether these two react with each other — it does not ask whether Phosphatidylserine is a good idea for someone in your situation. Here is what our Phosphatidylserine record says about it on its own.

Phosphatidylserine: dosing

There is no official standardized dose for phosphatidylserine. Amounts used in studies have varied, and the right amount for any individual is not well established.The safest approach is to follow the dose printed on the product label and not exceed it. Taking it earlier in the day may help reduce the chance of sleep problems.

About Atorvastatin

What Is Atorvastatin Used For?

Brand name: Atorvaliq

Atorvastatin is used alongside a healthy diet to lower LDL ("bad") cholesterol, triglycerides (blood fats), and other harmful lipids, while raising HDL ("good") cholesterol. It treats primary hyperlipidemia (high cholesterol), mixed dyslipidemia (mixed abnormal blood fats), hypertriglyceridemia (high triglycerides), and inherited conditions such as heterozygous and homozygous familial hypercholesterolemia — including in children aged 10 and older.

Beyond cholesterol control, atorvastatin is used to reduce the risk of heart attack, stroke, revascularization procedures, and angina (chest pain) in adults with coronary heart disease or multiple risk factors for it — including adults with type 2 diabetes who have risk factors for heart disease even without a confirmed heart disease diagnosis.

Taking Phosphatidylserine and Atorvastatin Together: Common Questions

Is it safe to take Phosphatidylserine with Atorvastatin?

Atorvastatin is filed under 7 classifications, and Phosphatidylserine has documented interactions with 2 drug classes — none of Atorvastatin's classifications are among them. A medication can belong to classes beyond those recorded in our dataset, so this describes how the check was run rather than guaranteeing safety.
