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

Generated from HelloPharmacist’s pharmacist-curated databases and editorial rules · Last generated Jul 11, 2026

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.

Celadrin contains 6 active ingredients. The one we have interaction data for is vitamin A palmitate, a form of vitamin A.

The other five are fatty acid esters — cetyl myristoleate, cetyl myristate, cetyl laurate, cetyl palmitoleate, and cetyl oleate — which make up the Celadrin fatty acid complex and a proprietary blend. The product also contains inactive ingredients (gelatin capsule, glycerin, soy lecithin, salmon fish oil, and carob) that help deliver and stabilize the active ingredients.

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 stiffness, Joint mobility, Cartilage health.
  • The closest evidence on file: Vitamin A is rated "Insufficient Reliable Evidence To Rate" for Osteoarthritis (Natural Medicines).

Vitamin A palmitate is effective for vitamin A deficiency. The evidence is possibly effective for oral leukoplakia (a precancerous mouth condition), aging skin, measles, ulcerative colitis, and a lung condition in premature infants called bronchopulmonary dysplasia.

We don't hold effectiveness data for the other active ingredients in this product.

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 palmitate is generally well tolerated at recommended amounts, but high doses build up in your body and can turn toxic. Serious effects from very high doses are rare but can include liver damage, a dangerous increase in brain pressure, severe headaches, and in extreme cases, coma or death.

Chronic overuse causes vitamin A toxicity symptoms like fatigue, dry and peeling skin, hair loss, and brittle nails. Young children are more sensitive to toxicity from a single large dose than adults.

On pregnancy and breastfeeding, the data shows vitamin A at recommended amounts is likely safe, but high doses (especially the retinol form) are possibly unsafe because they may cause birth defects — talk with your doctor or pharmacist before taking this while pregnant or nursing.

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.

Before taking this product, double-check it with any retinoid medications (acne treatments like tretinoin or isotretinoin) — the combination can cause dangerous vitamin A buildup. Also flag it if you take warfarin or other blood thinners, tetracycline antibiotics, or any drug that strains your liver.

The vitamin A in Celadrin interacts with all of these.

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 might be worth considering if you're looking for joint support and don't take retinoids, blood thinners like warfarin, tetracycline antibiotics, or medications that stress the liver. If you take any of those, or any prescription drug at all, check your medications with the tool on this page first.

Your pharmacist can tell you whether the vitamin A dose in this product is right for you.

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.
Is vitamin A in this product safe at the dose listed?
Vitamin A is generally well tolerated at recommended amounts. This product contains vitamin A palmitate, and as long as you stay within the recommended dose on the label, you should be fine — just don't exceed it, because high doses build up in your body and can become toxic.
Can I take this while pregnant or nursing?
At recommended supplement amounts, vitamin A is likely safe in pregnancy and while nursing. But high doses (especially as retinol) can cause birth defects. Since this product contains vitamin A palmitate, check the dose on the label and talk with your doctor or pharmacist before starting it — they can tell you whether it's the right choice for you right now.
What does vitamin A do in this product?
Vitamin A supports vision, skin health, and immune function. It's effective for treating vitamin A deficiency and has possibly effective evidence for aging skin, mouth lesions, measles, and some other conditions. The other active ingredients in Celadrin are fatty acid esters, but we don't have effectiveness data for those.
What are the other ingredients in Celadrin?
Besides vitamin A palmitate, Celadrin contains five fatty acid esters — cetyl myristoleate, cetyl myristate, cetyl laurate, cetyl palmitoleate, and cetyl oleate — which make up the Celadrin complex. The capsule itself is gelatin, and it also has glycerin, soy lecithin, salmon fish oil, and carob as inactive ingredients.
What side effects might I notice?
At recommended doses, vitamin A is generally well tolerated with minimal side effects. At very high doses, you might notice headache, dizziness, dry and peeling skin, rashes, hair loss, or brittle nails. Serious effects from high doses are rare and include liver damage and dangerous brain pressure — which is why you should never exceed the dose on the label.
Should I worry about the soy in this product?
The product contains soy lecithin as an inactive ingredient (an emulsifier that helps stabilize the formula). If you have a soy allergy, check with your pharmacist before taking it — the amount is typically very small, but it's worth confirming for your specific situation.
