Niacin inactive ingredients by manufacturer

Wondering whether your Niacin has lactose, gluten, soy, a dye or gelatin in it? The medicine is the same, but the fillers, coatings and colors differ from one company to the next. This page shows what each Niacin product's FDA label lists, so you can find a version that leaves out what you avoid and ask your pharmacist for it by its NDC.

We have read the FDA labels of 24 of the 24 current Niacin products on the market today, from 13 companies listing it with the FDA, and lined them up side by side.

Curated and coded by Dr. Brian Staiger, PharmD, BCPS, clinical pharmacist. The ingredient groups this page checks for (what counts as a gluten source, a synthetic dye, soy and so on) are his classification; the lists themselves are the manufacturers' own FDA labels. Updated October 6, 2026. Rebuilt daily from the FDA directory; labels re-read when the FDA publishes a new version.

A product with none of these listed is not certified to be without them: the label says what the manufacturer declared, and the source of a starch or a flavor is often not stated. The companies are the FDA's labelers, which include repackagers and distributors selling another company's product under their own label. The NDC opens the product's own page, with the full label and its inactive-ingredient notes.

At the pharmacy counter

How to use this at the pharmacy counter

  1. Pick the company whose list suits you and copy the NDC from the table. Many pharmacies order from wholesalers that carry several companies' versions and can request a particular one if you ask before the prescription is filled; some buy from one contracted source only, and a few insurance plans cover only certain NDCs, so ask the pharmacist to check.
  2. Treat "does not list" as exactly that. The label is what the manufacturer declared; a flavor or a starch may have an unstated source, and lines change. For celiac disease or a serious allergy, ask the manufacturer's medical information line for a written statement about the lot you have.
  3. Check the bottle each refill. A different company usually means a different shape, color and inactive-ingredient list; the pharmacist can tell you who made it, and the two-NDC comparison shows the difference line by line.
  4. If you need one company's version kept constant, ask your prescriber to write that company or the NDC on the prescription and tell the pharmacy you need it held. Rules vary by state and plan, so confirm with the pharmacist.

Common questions about Niacin inactive ingredients

Is Niacin gluten-free?
This page cannot certify any Niacin product gluten-free; it reports what each label declares. Of the 24 products checked, none lists a wheat, barley, rye or gluten ingredient, and none lists a starch without a stated source. If you have celiac disease, ask the manufacturer's medical information line for a written gluten statement for the lot you have.
Does Niacin contain lactose?
3 of 24 checked Niacin products list lactose; 21 do not: Amneal (500 mg extended-release tablet, 750 mg extended-release tablet and 1000 mg extended-release tablet), Avondale (500 mg tablet), AvPAK (500 mg extended-release tablet) and Chartwell RX (500 mg extended-release tablet and 1000 mg extended-release tablet) and 8 other companies. The lactose in a tablet or capsule is a small amount, but people with a milk allergy or a strong intolerance often prefer a version that does not list it.
Does Niacin contain soy?
11 of 24 checked Niacin products list a soy ingredient (soybean oil or soy lecithin); 13 do not: Amneal (500 mg extended-release tablet, 750 mg extended-release tablet and 1000 mg extended-release tablet), Aurobindo (500 mg extended-release tablet, 750 mg extended-release tablet and 1000 mg extended-release tablet), AvPAK (500 mg extended-release tablet) and Lupin (750 mg extended-release tablet) and 2 other companies. Soy lecithin is the usual form and the amount is small, but people with a soy allergy often prefer a version that does not list it.
Is there a dye-free Niacin?
7 of 24 checked Niacin products list a synthetic dye (an FD&C or D&C colorant); 17 do not: Aurobindo (500 mg extended-release tablet, 750 mg extended-release tablet and 1000 mg extended-release tablet), Avondale (500 mg tablet), Chartwell RX (500 mg extended-release tablet and 1000 mg extended-release tablet) and Emerald Therapeutics (500 mg tablet) and 5 other companies. Colorants often differ by strength within one company's line, so compare the lists above strength by strength.
Does Niacin contain gelatin?
No checked Niacin product lists gelatin on its label. Gelatin is usually bovine or porcine and the label rarely says which; for kosher, halal or vegetarian needs, ask the manufacturer.
Why do the inactive ingredients differ between manufacturers?
A generic must match the brand's active ingredient, strength, dose form and how it is absorbed; its fillers, binders, coatings and colorants are the manufacturer's own choice. That is why one Niacin product can list lactose and a dye while another from a different company lists neither.
Can my pharmacy give me a specific manufacturer's version?
Often, if you ask before the prescription is filled: many pharmacies order from wholesalers that carry several companies' versions and can request a particular one. Some pharmacies buy a generic from one contracted source only, and a few insurance plans cover only certain NDCs, so ask the pharmacist to check. Give them the NDC from this page; the company name alone is often enough.
How current is this list?
The products are the ones in the FDA's current NDC directory as of October 6, 2026. The list is rebuilt every day, the FDA directory is re-imported every week, and each inactive-ingredient list is the manufacturer's FDA label as our label sync last read it, re-read when the FDA publishes a new version. Formulations change, so check the label on your own bottle and ask your pharmacist if a refill looks different.

Sources: the products are the finished Niacin products in the FDA's current NDC directory (openFDA), as of October 6, 2026; each inactive-ingredient list is the manufacturer's FDA Structured Product Label via DailyMed, as our label sync last read it. The concern groups are HelloPharmacist's classification of the names the label declares.
