Which company (brand) sells valproic acid bulk product, and who manufactures it?
“Valproic acid” is sold under multiple brand names and in several formulations (including brand-name capsules and generic products). The actual manufacturing company depends on the specific label/NDC, because different generic suppliers can make chemically equivalent products.
How to find the actual manufacturing plant for a specific valproic acid product (NDC/label)?
If you’re trying to identify the “manufacturer” for a particular valproic acid product (for example, for sourcing or compliance), the most reliable way is to match the product you mean by:
- Brand name (or generic name + strength)
- Dosage form (delayed-release capsules, sprinkle capsules, syrup, etc.)
- Strength
- NDC number
Once you have the NDC, you can look up the labeled manufacturing site and the company associated with that specific product.
Is there a single “bulk valproic acid” manufacturer list?
No. There isn’t one universal “valproic acid bulk manufacturer,” because:
- Different companies make different finished-dose products.
- Finished-dose manufacturers may use different suppliers for the active ingredient (API).
- API sourcing can also change over time, so the manufacturer associated with one NDC may not match another.
If you mean API (active pharmaceutical ingredient) versus finished-dose pills/capsules
Your answer changes depending on whether you want:
- API manufacturer (valproic acid raw material), or
- finished-dose product manufacturer (the capsules/tablets that patients receive)
Most public “who makes it” searches are easier for the finished-dose product (via NDC), while API sourcing is often handled through supplier qualification and contract documentation.
Fastest way to get the correct manufacturer
Share the exact product details you’re looking at:
- Strength (e.g., 250 mg, 500 mg, 250 mg/5 mL)
- Dosage form (enteric-coated/divalproex ER vs valproic acid DR, capsules vs syrup)
- Brand or generic name
- NDC (best)
- Country (US, EU, etc.)
Then I can help you pinpoint the manufacturer for that specific labeled product (finished dose) and, if relevant, where to verify the API source through the right references.
Source check (patent/exclusivity references, when relevant)

If you tell me the valproic acid strength + dosage form (and ideally the NDC), I can narrow it down to the specific manufacturer tied to that product.
