Astaxanthin and Gadobenate Dimeglumine

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 Gadobenate Dimeglumine and Astaxanthin 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.

Astaxanthin safety at a glance

Astaxanthin overall Use caution Generally well tolerated in studies, but long-term safety data are limited.
Pregnancy Avoid Not enough safety data, so it is best to avoid during pregnancy.
Breastfeeding Avoid Not enough safety data, so it is best to avoid while breastfeeding.

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

How we checked

Why No Interaction Is Listed for Gadobenate Dimeglumine

Interactions in our licensed database are recorded against drug classes, not just single drug names. Gadobenate Dimeglumine is filed under a single classification — oral drugs. Astaxanthin has documented interactions with 2 drug classes — the most serious being cytochrome p450 2b6 (cyp2b6) substrates (moderate) and cytochrome p450 3a4 (cyp3a4) substrates (moderate) — and none of Gadobenate Dimeglumine’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 Astaxanthin Itself Has Been Linked To

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

  • Stomach pain / Diarrhea Additional detail

    “Orally, astaxanthin 6 mg daily has caused two cases of increased bowel movements and two cases of red fecal color. A higher dose of astaxanthin (AstaCarox, AstaReal AB) 40 mg daily has caused severe stomach/abdominal pain in two patients.”

“Activated charcoal is the one supplement I would treat as a hard stop around a MultiHance (gadobenate dimeglumine) MRI scan. It is the sole major-rated entry among the 17 ingredients on file, and it can bind drugs and lower their levels in the body even when a medicine is not taken by mouth.”

About Astaxanthin

What is Astaxanthin?

Astaxanthin
  • Antioxidant support
  • Skin health and aging
  • Eye health
  • Exercise recovery
  • Heart and inflammation support

Astaxanthin is a reddish carotenoid pigment with strong antioxidant activity in the lab, and it is widely promoted for skin, eye, heart, and exercise benefits. Early human studies are promising for a few uses, but the overall evidence is still limited and not strong enough to make firm claims. It appears generally well tolerated at typical supplement doses, but talk with your pharmacist or doctor before starting it.

Pigment extracted from microalgae (mainly Haematococcus pluvialis), yeast, and some seafood · Capsules, soft gels, tablets, and as an ingredient in some skin creams

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

Astaxanthin: dosing

There is no official standardized dose for astaxanthin, and amounts used in studies have varied. Because of this, the best approach is to follow the directions on the product label.Astaxanthin is fat-soluble, so it is often taken with a meal that contains some fat to help absorption.
