Product Overview

Vitamin B3 is an essential water-soluble vitamin mainly available in two core forms: Nicotinic Acid and Niacinamide, each with distinct functional advantages and application scenarios.

 
Nicotinic Acid (CAS 59-67-1) is widely applied in food fortification and dietary supplement formulations, focusing on supporting healthy metabolic function and maintaining normal human physiological metabolism.
 
Niacinamide (CAS 98-92-0), the cosmetic-grade form of Vitamin B3, serves as a popular skincare raw material that helps improve and maintain healthy skin condition. Both forms are high-purity, stable raw materials, widely supplied for food, nutritional and cosmetic industrial formulation needs.

Character

Both nicotinic acid and niacinamide are white crystalline powders with good solubility in water. They are stable under proper sealed storage conditions. Niacinamide is known for its excellent skin compatibility without causing flushing, making it suitable for both oral and topical applications.


 

Main Functions

 

1.Essential Nutrient for Energy Metabolism: Both nicotinic acid and niacinamide serve as essential B-vitamin forms supporting energy metabolism in nutritional formulations.

2.Skin Barrier Support (Niacinamide): Niacinamide is widely used in skincare formulations for skin conditioning and barrier support, without the flushing effect associated with high-dose nicotinic acid.

3.No Flushing Form (Niacinamide): Niacinamide provides B3 nutrition without causing skin flushing, making it suitable for both supplement and cosmetic applications.

4.Food Fortification Grade (Nicotinic Acid): Nicotinic acid is suitable for food fortification and dietary supplement formulations as a cost-effective B3 nutrient source.


 

Applications

1.Dietary Supplements Both nicotinic acid and niacinamide are widely used in tablets, capsules and powder blends as B3 nutrient ingredients. Niacinamide is preferred when flushing needs to be avoided.

2.Cosmetic and Personal Care Mainly uses niacinamide in skincare creams, serums and lotions for skin conditioning. Nicotinic acid is rarely used in cosmetic formulations due to potential skin flushing.
