Frequently Asked Questions
Q1. How does nicotinic acid differ from niacinamide (nicotinamide)?
They are both forms of vitamin B3, but they differ chemically and in how they behave:
- Nicotinic acid has a carboxylic acid group and is the classic "niacin" form.
- Niacinamide (nicotinamide) is the amide form of the same vitamin.
The key practical difference is that nicotinic acid can cause a harmless flushing or tingling sensation in the skin, while niacinamide does not cause flushing. Both deliver vitamin B3 activity, but they are chosen for different end-uses.
Q2. Are nicotinic acid and niacinamide interchangeable?
Not always. They both provide vitamin B3, but the right choice depends on the product:
- For dietary supplements and food fortification, nicotinic acid is the traditional form.
- For skincare and cosmetics, niacinamide is usually preferred because it is gentler and does not cause the flush that nicotinic acid can trigger.
- For applications where a flushing-free form is critical, niacinamide is the safer option.
Q3. What are the typical specifications and purity?
We supply nicotinic acid in high-purity grades (typically ≥99%) with defined assay, loss on drying, and particle size to suit tablets, capsules, powders, and premixes. Full COA, MSDS, and specification sheets are available.
Q4. What is the recommended usage?
Dosage follows regulatory limits for food fortification and supplement labeling in your target market. We recommend confirming the applicable vitamin B3 allowance and labeling rules for each market before formulating.
Q5. How is nicotinic acid supplied and packaged?
Standard packing: 25kg/drum. Inner double plastic bags. Custom packaging is acceptable.
