HelloPharmacist Scorecard of Celadrin by Bluebonnet

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.

From our pharmacy team — supplement deep dive

What’s inside

Low disclosure
Ingredient Transparency · database check
Low

Most active ingredients don't disclose an individual amount — you can't tell how much of each you're getting.

Why this rating?
  • The label discloses an exact amount for 0 of its 6 active ingredients.
  • “Celadrin Fatty Acid Complex” is a proprietary blend — the label gives one combined amount (1,050 mg) without saying how much of each component you get.
  • “Proprietary Blend of Esterified Fatty Acid Carbons” is a proprietary blend — the label doesn't break down how much of each component you get.

Bluebonnet Celadrin is a 6-ingredient softgel with vitamin A palmitate as its active ingredient; the rest are fatty acid compounds (cetyl myristoleate, cetyl myristate, cetyl laurate, cetyl palmitoleate, and cetyl oleate) that form the Celadrin Fatty Acid Complex. Inactive ingredients include gelatin, glycerin, soy lecithin, salmon fish oil, and carob.

Does it work?

Not established
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 established

The graded evidence we hold for these ingredients covers different conditions than the ones this product is marketed for, so there's no established rating for its stated use — see Vitamin A's own graded uses on its monograph.

Why this rating?
  • The label markets this product for: promote flexibility and healthy joint function.
  • We looked for evidence on: Osteoarthritis, joint mobility, cartilage health, inflammation.
  • The closest evidence on file: Vitamin A is rated "Insufficient Reliable Evidence To Rate" for Osteoarthritis (Natural Medicines).

Vitamin A is effective for treating vitamin A deficiency. It's possibly effective for oral leukoplakia (a precancerous mouth condition), aging skin, measles, ulcerative colitis, and bronchopulmonary dysplasia (a lung condition in premature infants).

The data we hold doesn't establish effectiveness ratings for the other active components.

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.

Vitamin A is generally well tolerated at recommended doses, but high doses build up in your body and can become toxic. At recommended levels, vitamin A is appropriate; you should avoid high-dose supplements unless your doctor directs it.

The safety data advises against high-dose vitamin A (especially as retinol) during pregnancy because of the risk of birth defects. In rare cases at very high doses, vitamin A has caused brain swelling, liver damage, and severe headaches; chronic overuse can cause dry, cracking skin, hair loss, and brittle nails.

Meds to double-check

Major interaction found
Known Interaction Concern · database check
Major identified

At least one ingredient has a documented Major-severity interaction. Check your medications for a personalized result.

Why this rating?
  • 1 of the 1 matched ingredient can interact with medications — Vitamin A.
  • The most serious interaction on file is rated Major.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs.
  • For scale: 388 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.

Check this product against any retinoid medications (Major severity), blood thinners like warfarin, tetracycline antibiotics, and drugs that can affect your liver (all Moderate severity). We could not check the other ingredients in this product for interactions.

The bottom line

Scorecard at a glanceFormula with limited ingredient disclosure with no established evidence rating for its marketed use. Major medication interactions have been identified, and safety information is well characterized.

Celadrin's vitamin A palmitate is well tolerated at the dose in this supplement, but it can interact with retinoid medications, blood thinners, tetracycline antibiotics, and some other drugs. If you take any prescription medications, run them through the checker on this page before you start.

Celadrin by Bluebonnet: Common Questions

Does Celadrin by Bluebonnet interact with any medications?
Yes. Based on its ingredients, Celadrin has a known interaction with 387 medications, including 9 rated major. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Celadrin contains a single active ingredient, and that one ingredient can interact with many different medications on its own. We check it against each medication and show the mechanism 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 Celadrin if I'm pregnant or breastfeeding?
The safety data is mixed: vitamin A is rated possibly unsafe in pregnancy because high doses carry a risk of birth defects. At recommended supplement levels you're in safer territory, but you should talk with your doctor or pharmacist before starting, especially if you're pregnant or planning to be.
What is cetyl myristoleate, and does it do anything?
Cetyl myristoleate is one of several fatty acid compounds in Celadrin's proprietary blend. We hold no interaction data for it, and the product facts don't specify its role or effectiveness.
Will Celadrin help my skin look younger?
Vitamin A is possibly effective for aging skin according to the data we hold. That said, 'possibly effective' means the evidence supports it but isn't definitive — results vary, and you should have realistic expectations.
What are the side effects of vitamin A at this dose?
At recommended doses below the upper limit (10,000 IU/day for adults), vitamin A is generally well tolerated. Serious side effects like skin peeling, hair loss, and liver problems happen at high chronic doses — not typical supplement levels.
Is there soy in this product?
Yes — soy lecithin is listed as an inactive ingredient. If you have a soy allergy, talk with your pharmacist before taking it.
Can I take Celadrin with my tetracycline antibiotic?
High doses of vitamin A combined with tetracycline antibiotics can increase the risk of increased pressure in your skull. This product's dose matters; before you take them together, check with your pharmacist or doctor to make sure the vitamin A level is safe.
