HelloPharmacist Scorecard of D-Cursinol Plus by Bronson Laboratories

Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.

What’s inside

Full disclosure
Ingredient Transparency · database check
Full

Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 2 of its 2 active ingredients.
  • No proprietary blends here — you can verify the dose of every single component.

D-Cursinol Plus contains 2 active ingredients: astaxanthin, a carotenoid antioxidant, and Decursinol 50(TM). The product also includes inactive ingredients (cellulose, silicon dioxide, stearic acid, magnesium stearate, and gelatin) that serve as fillers and capsule material.

Does it work?

Couldn't assess
Evidence for Intended Use · database check
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed
Not assessable

This is a single-ingredient Astaxanthin product and its label doesn't state a use — see Astaxanthin's own graded uses on its monograph.

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.

The evidence for astaxanthin's effectiveness is not established in our data. We have insufficient reliable evidence to rate it for age-related cognitive decline, macular degeneration (AMD), aging skin, Alzheimer disease, athletic performance, or carpal tunnel syndrome.

We hold no effectiveness data for Decursinol 50(TM).

The evidence, ingredient by ingredient Astaxanthin

How safe is it?

Well-documented data
Safety Information · database check
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

Why this rating?
  • We hold adverse-effect (side-effect) data for 1 of the 1 matched ingredient.
  • Pregnancy & breastfeeding safety ratings cover 1 of 1.
  • General safety write-ups exist for 1 of 1.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Astaxanthin is generally well tolerated in studies, though long-term safety data are limited. The most common side effects are abdominal pain, diarrhea, and red-colored stools.

At typical doses (6 mg daily), a small number of trial participants reported increased bowel movements and red stools; at higher doses (40 mg daily), two people experienced severe stomach pain. Due to insufficient safety data, astaxanthin is not recommended during pregnancy or while breastfeeding.

Talk with your doctor or pharmacist for personalized advice.

The most serious documented interaction for these ingredients is Moderate. Check your medications for a personalized result.

Why this rating?
  • 1 of the 1 matched ingredient can interact with medications — Astaxanthin.
  • The most serious interaction on file is rated Moderate.
  • For scale: 672 individual medications appear in the full list. A big number alone doesn't make a product dangerous — what matters is whether YOUR medication is on it, so run yours through the interaction checker on this page.

If you take medications broken down by your liver's CYP3A4 or CYP2B6 enzymes—including certain heart and seizure drugs, some statins, and many others—double-check them before adding this product. Astaxanthin may lower their levels (Moderate severity).

D-Cursinol Plus by Bronson Laboratories: Common Questions

Does D-Cursinol Plus by Bronson Laboratories interact with any medications?
Yes. Based on its ingredients, D-Cursinol Plus has a known interaction with 671 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
D-Cursinol Plus contains 2 active ingredients, and an interaction can come from any of them. We check every ingredient, combine the results into one list per medication, and show which ingredient and mechanism is responsible.
Where does this information come from?
The product label data comes from the NIH Dietary Supplement Label Database (DSLD); the interaction data is built on the Natural Medicines database and reviewed by HelloPharmacist pharmacists.
Can I take D-Cursinol Plus if I'm pregnant or breastfeeding?
The safety data aren't there yet for astaxanthin in pregnancy or while breastfeeding, so it's best to avoid it. Talk with your doctor or pharmacist about what's right for you.
What side effects might I notice?
Most people tolerate it well. The most common side effects are abdominal pain, diarrhea, and red-colored stools. Higher doses have rarely caused severe stomach pain.
Does astaxanthin actually work for anti-aging or brain health?
We don't have reliable evidence to say whether it works for age-related cognitive decline, macular degeneration, aging skin, or other conditions yet. The research isn't established in our data.
Why can't you check the Decursinol ingredient for drug interactions?
We don't have safety or interaction data on file for Decursinol 50(TM), so we can't tell you whether it interacts with your medications. Your pharmacist may be able to help you track that down.
Should I be worried about long-term use?
Astaxanthin seems well tolerated in studies, but we don't have enough long-term safety data to know how it performs over months or years. It's a good reason to check in with your pharmacist or doctor regularly.
