Vitamin B5, also known as pantothenic acid, is a water-soluble vitamin that plays an essential role in many bodily functions. It is a component of coenzyme A, which is involved in the metabolism of carbohydrates, fats, and proteins. Vitamin B5 also plays a role in the synthesis of cholesterol, hormones, and neurotransmitters.
The recommended daily intake of vitamin B5 for adults is around 5 milligrams per day, although this can vary based on age, sex, and other factors. Vitamin B5 can be found in a variety of foods, including meat, poultry, fish, whole grains, and vegetables.
Deficiency of vitamin B5 is rare, as it is found in many foods. However, severe deficiency can lead to a condition known as pantothenic acid deficiency, which can cause symptoms such as fatigue, insomnia, numbness and tingling in the hands and feet, and gastrointestinal disturbances.
Supplements of vitamin B5 are available in the form of capsules or tablets, and are sometimes used to treat acne, stress, and other conditions. However, more research is needed to determine the effectiveness of these supplements. In general, it is best to obtain vitamins and nutrients through a balanced diet rather than relying on supplements.
