Vitamin B5

Updated: 2026-09-15

Overview

Vitamin B5, or pantothenic acid, is a vital nutrient involved in energy metabolism and the synthesis of coenzyme A (CoA). It is widely used in dietary supplements, pharmaceuticals, and cosmetics due to its role in cellular processes. As a water-soluble vitamin, it must be replenished regularly through diet or supplementation. Pantothenic acid is naturally found in foods like meat, eggs, and whole grains. Industrially, it is produced synthetically for commercial use. Its applications span human health, animal nutrition, and skincare, making it a versatile compound in B2B markets.

Physical and Chemical Properties

Vitamin B5 appears as a yellow viscous oil or white crystalline powder. It is highly soluble in water and polar solvents, which facilitates its use in liquid formulations. The compound is heat-sensitive and may degrade under high temperatures or prolonged exposure to light. With a molecular weight of 219.23 g/mol, its stability is optimal in neutral pH environments. The melting point ranges between 183-185°C, and its estimated boiling point is 551.5±50.0°C. These properties dictate its storage and handling requirements in industrial settings.

Main Applications

Vitamin B5 is primarily used in dietary supplements to support energy production and reduce fatigue. In pharmaceuticals, it aids in wound healing and anti-inflammatory treatments. The cosmetic industry values it for its moisturizing and skin-repairing properties, often incorporating it into creams and serums. Animal feed formulations also include pantothenic acid to promote growth and metabolic health in livestock. Its versatility and safety profile make it a staple in multiple industries, driving consistent B2B demand.

Safety and Storage

Vitamin B5 is generally recognized as safe (GRAS) with minimal toxicity. Overconsumption may lead to mild diarrhea or gastrointestinal discomfort, but serious adverse effects are rare. Proper storage in cool, dry conditions away from light and moisture is critical to maintain its efficacy. For industrial procurement, suppliers should provide certificates of analysis (CoA) to verify purity and stability. Bulk shipments require sealed containers to prevent degradation during transit, ensuring product integrity for end-users.

B2B Procurement Guide

When sourcing Vitamin B5, prioritize suppliers with ISO or GMP certifications to guarantee quality. Request batch-specific CoAs to confirm purity (typically 98-99%) and check for contaminants. Pricing varies based on quantity and purity, with bulk orders (1+ metric tons) often discounted. Consider logistical factors like storage facilities and shelf life, especially for international shipments. Establish long-term contracts with reliable suppliers to mitigate price fluctuations and ensure consistent supply for manufacturing or resale.
