The bottom line No known interaction

We found no known interaction between Lecithin and Citalopram 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.

Lecithin and Citalopram

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 Citalopram and Lecithin 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.

Worth understanding: our licensed dataset holds no drug-interaction record for Lecithin at all — not against Citalopram, and not against any other medication we track. This verdict therefore rests on the absence of any recorded data, not on research that looked at this combination and found nothing. We cannot rule an interaction out.

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.

What to actually watch for

What Lecithin Itself Has Been Linked To

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

  • Stomach pain / Diarrhea / Nausea Additional detail

    “Orally, lecithin may cause abdominal pain, diarrhea, fullness, and nausea.”

Everything above comes from the Natural Medicines adverse-effect record for Lecithin — expand a row for the licensed statement it rests on. We read the ADVERSE REACTIONS section of Citalopram’s FDA label too, and the two lists don’t meaningfully overlap — which is why no Citalopram column appears here.

About Lecithin

What is Lecithin?

  • High cholesterol
  • Liver health
  • Brain and memory support
  • Breast inflammation during breastfeeding (mastitis/clogged ducts)
  • Dry skin and skin conditions

Lecithin is a natural fatty substance found in foods and made by the body that is widely used as a supplement and food emulsifier. Evidence supporting most of its health claims is limited, though it is generally considered safe for most people when taken in normal amounts. Talk to your pharmacist or doctor before starting it, especially if you have allergies to soy or egg.

Fatty substance extracted from soybeans, eggs, or sunflower seeds · Capsules, softgels, granules, powder, liquid, and as a food additive

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

Lecithin: dosing

There is no official standardized dose of lecithin for any health condition. The amount used varies widely depending on the product and the reason for use.The best approach is to follow the directions on the product label and not take more than recommended.
