Interaction report

Aegeline and Psyllium (OTC drug)

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 Psyllium (OTC drug) and Aegeline 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.

How we checked

Why No Interaction Is Listed for Psyllium (OTC drug)

Interactions in our licensed database are recorded against drug classes, not just single drug names. Psyllium (OTC drug) is filed under a single classification — oral drugs. Aegeline has documented interactions with 1 drug class — the most serious being cytochrome p450 3a4 (cyp3a4) substrates (minor) — and none of Psyllium (OTC drug)’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 Aegeline Itself Has Been Linked To

This is not an interaction — nothing below involves Psyllium (OTC drug). It is the side-effect record for Aegeline on its own, from the licensed Natural Medicines monograph. If something new turns up after you add Aegeline, this list is the first place to look. 2 entries are worth acting on rather than waiting out — marked below.

See Every Supplement That Interacts With Psyllium (OTC drug)

This page covers Aegeline only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Psyllium (OTC drug) page lists 17 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), Coffee Charcoal (moderate), European Mandrake (moderate), Glucomannan (moderate) and Guar Gum (moderate).

By severity: 1 major · 7 moderate · 9 minor.

From our pharmacist’s overview on the Psyllium (OTC drug) page

“Activated charcoal tops the psyllium (Metamucil) list and is the one entry rated major. Charcoal binds many medicines in the gut and can cut how much of them reaches the body, so pairing it with anything you take by mouth deserves real caution, and I would read that entry before the rest.”

About Aegeline

What is Aegeline?

  • Weight loss
  • Fat burning / metabolism support
  • Sports and bodybuilding supplements
  • General 'energy' products

Aegeline is a compound originally identified in the bael tree (Aegle marmelos) that gained attention because it was added to some weight-loss and workout supplements. It is best known for being linked to serious liver injury in a product called OxyELITE Pro, and U.S. regulators warned against products containing it. There is no good evidence it safely helps with weight loss, and it should generally be avoided.

Derived from compounds found in Aegle marmelos (bael tree); aegeline is also made synthetically · Capsules and tablets (historically in some weight-loss and sports supplements)

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

Aegeline: dosing

There is no established safe or effective dose of aegeline. Because it has been linked to liver injury and is not considered a lawful dietary ingredient in the United States, there is no recommended amount.We do not recommend taking aegeline.
