D-Pantothenic acid is widely used in the pharmaceutical and nutraceutical industries as a vital component in vitamin B5 supplements. It plays a crucial role in supporting energy metabolism by aiding in the synthesis of coenzyme A (CoA), which is essential for breaking down carbohydrates, fats, and proteins. This makes it a key ingredient in dietary supplements aimed at boosting energy levels and reducing fatigue. Additionally, it is incorporated into skincare products for its moisturizing and healing properties, helping to improve skin barrier function and promote wound healing. In animal nutrition, it is added to feed to enhance growth, improve coat condition, and support overall health in livestock and pets. Its applications also extend to the food industry, where it is used as a fortifying agent in various products to ensure adequate nutritional intake.
