Pantothenic acid is popularly known as vitamin B5. This water-soluble vitamin acts as an antioxidant and plays a very important role in the decomposition of carbohydrates, fats and proteins. In addition, it is used in the production of several enzymes and helps the central nervous system to communicate with the brain. It has a broad role in the human body, so preventing pantothenic acid deficiency is very important.
Forms of Pantothenic Acid and Therapeutical Values
Pantothenic acid can be found in three forms:
- Calcium pantothenate
- Vitamin B5
Panthenol is the provitamin of B5, and because it has moisturizing properties, it is frequently included in cosmetic products. Skin is able to assimilate panthenol quickly. Because it can be quickly absorbed, it is included in numerous ointments for sunburns and minor skin disorders. Besides moisturizing the skin, it is also able to relieve itch and inflammation.
Calcium pantothenate is mainly used in the treatment of acne, but it also has many other functions. More precisely, it is able to:
- Reduce stress levels
- Regulate cholesterol levels
- Improve athletic performance
- Improve the immune system
- Promote weight loss
- Alleviate headaches
- Improve the symptoms of arthritis
Besides that, calcium pantothenate helps in the prevention of hair loss and cardiovascular diseases.
Vitamin B5 shares several beneficial effects with the other two pantothenic acid forms. Therefore, it is also used to heal wounds. Diabetic ulceration and testicular torsion are other health conditions that can be improved with pantothenic acid.
