 Vitamin  B5 (Pantothenic acid)

• Pantothenic acid is vitamin B5. It is widely found in both plants and animals including meat, vegetables, cereal grains, legumes, eggs, and milk. 
• Pantothenic acid helps the body utilize carbohydrates, proteins, and lipids. It is also important for maintaining healthy skin. 
• Vitamin B5 is available as D-pantothenic acid, as well as dexpanthenol and calcium pantothenate, which are chemicals made in the lab from D-pantothenic acid. 
• People most commonly use pantothenic acid for pantothenic acid deficiency. Dexpanthenol, a chemical similar to pantothenic acid, is used for skin irritation, nasal swelling, wound healing, and other conditions, but there is no good scientific evidence to support these uses.

4)Effects of deficiency 

• Skin symptoms
• Pantothenic acid deficiency. Taking 5-10 mg of pantothenic acid by mouth daily prevents and treats pantothenic acid deficiency.

5)Side Effects

• When taken by mouth: Pantothenic acid is likely safe for most people. The recommended amount for adults is 5 mg per day. Larger amounts (up to 1 gram) seem to be safe for most people. But taking larger amounts increases the chance of side effects such as diarrhea. 
• When applied to the skin: Dexpanthenol, a chemical similar to pantothenic acid, is possibly safe when used short-term. 
• When given as a nasal spray: Dexpanthenol is possibly safe when used short-term. 
• When applied into the eye: Dexpanthenol is possibly safe when used short-term.
