Agar and Bempedoic Acid

Here is the interaction we found between these two, with the evidence behind it.

Minor

ORAL DRUGS

Why this applies to Bempedoic Acid

Bempedoic Acid falls under ORAL DRUGS — the group Agar interacts with.

Agar forms a thick gel, which may disrupt the absorption of nutrients and medications. Animal research suggests that consuming a diet consisting of 5% to 10% agar alters the absorption of nutrients from the diet. In one study, consuming a diet composed of 10% agar reduced the absorption of all evaluated minerals. Theoretically, agar may also impair the absorption of oral drugs.
Severity Minor Likelihood Possible Evidence D

Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists.

Dr. Brian Staiger, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the simple version. Agar is a seaweed fiber that swells into a thick gel in your stomach. The concern is that this gel could trap a swallowed pill like bempedoic acid (Nexletol) and keep some of it from being absorbed. If less gets into your blood, the medicine may not lower your LDL (bad cholesterol) as well as it should.

I want to be honest about how solid this is: it's theoretical, based mostly on animal studies showing agar can reduce absorption of nutrients. We don't have human proof that it weakens bempedoic acid specifically. To be safe, don't take them at the same moment. Separating them by a few hours is a reasonable habit. Run it by your pharmacist or doctor first, and keep your cholesterol checks on schedule.

See Every Supplement That Interacts With Bempedoic Acid

This page covers Agar only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Bempedoic Acid page lists 21 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), African Wild Potato (moderate), Banderol (moderate), Caffeic Acid (moderate) and Coffee Charcoal (moderate).

By severity: 1 major · 11 moderate · 9 minor.

From our pharmacist’s overview on the Bempedoic Acid page

“Activated charcoal is the ingredient I would rule out entirely on bempedoic acid (Nexletol), a daily tablet for lowering LDL cholesterol. It carries the only major rating of the 21 ingredients on file because it can trap the drug in the gut and shrink the dose your body absorbs.”

About Agar

What is Agar?

Agar
  • Constipation
  • Weight loss
  • Vegetarian gelatin substitute
  • Source of dietary fiber
  • Appetite control

Agar is a plant-based gel made from red seaweed that is widely used as a vegetarian alternative to gelatin and as a source of dietary fiber. It is sometimes taken as a bulk-forming laxative or weight-loss aid, but solid human evidence for these health uses is limited. It is generally considered safe as a food, but you should drink plenty of water with it and check with your pharmacist before using it as a supplement.

About Bempedoic Acid

What Is Bempedoic Acid Used For?

Brand name: Nexletol

Nexletol (bempedoic acid) is used in adults to reduce the risk of major cardiovascular events — including cardiovascular death, heart attack, stroke, and procedures to open blocked arteries — in people at increased cardiovascular risk who are unable to take recommended statin therapy.

Nexletol is also used alongside diet and exercise to lower LDL cholesterol in adults with high cholesterol (hypercholesterolemia), including a genetic form called heterozygous familial hypercholesterolemia (HeFH). It can be used with other cholesterol-lowering medicines or alone when combining with another therapy isn't possible.
