Vitamin B5 - Functions, Deficiency, and Management

Introduction:

Vitamins are a class of chemical substances that are thought to be necessary for the human body's regular metabolism and physiological processes. These, however, must be obtained in modest amounts from the diet because the body is unable to generate them endogenously.

What Is the Importance of B Group Vitamins?

Humans require adequate amounts of vitamins for their daily needs, and they are classified as follows:

• Fat-soluble vitamins such as A, D, E, and K.

• Water-soluble vitamins such as vitamin C and eight types of vitamin B which include:

  • Thiamine (vitamin B1).

  • Riboflavin (vitamin B2).

  • Niacin (vitamin B3).

  • Pantothenic acid (vitamin B5).

  • Vitamin B6 (pyridoxine)

  • Folate (vitamin B9).

  • Vitamin B12 (cyanocobalamin)

These various B-group vitamins are typically produced in plant chloroplasts and are necessary for coenzyme metabolism and cellular activity (plant origin). The one exception to this rule is vitamin B12, which is mostly produced by bacteria and stored in food items derived from animals (mammals' foreguts are where the synthesis occurs).

What Is Vitamin B5?

Pantothenic acid, also called pantothenate or vitamin B5, is a water-soluble vitamin discovered by Roger J. Williams in 1919. Historically, pantothenic acid deficiency was also implicated in the 'burning feet syndrome', which affected the war prisoners in Asia during World War II. The condition was known to be improved after pantothenic acid supplementation and not when other B-complex vitamins were given.

For the synthesis of coenzyme-A (CoA) and the metabolism of carbohydrates, proteins, and lipids, pantothenic acid is a necessary nutrient. It is a structural amide formed by the union of pantoic acid with beta-alanine. Vitamin B5 is a vital component of coenzyme A (CoA) and the vitamin B2 complex. Its structure is found in its alcohol analog, the provitamin panthenol, as calcium pantothenate. Vitamin B5 is crucial for functioning in the composition of coenzyme A and phosphopantetheine, which are involved in fatty acid metabolism. The adequate intake (AI) for adults is around five milligrams per day (mg/day).

What Are Some of the Sources of Vitamin B5?

It is common to find vitamin B5 in both plant and animal sources.

Some of the vitamin B5 foods are as follows:

• Meat includes beef, pork, chicken, turkey, duck, and especially animal parts like kidney and liver.

• Fish include shellfish, salmon, and lobster.

• Cereals and whole grain breads. Although processing may eliminate as much as 75 percent of the vitamin B5 content, whole grains are still a rich source of B5.

• Dairy products include yogurt, milk, egg yolks, and milk derivatives.

• Legumes such as split peas, soybeans, and lentils.

• Mushrooms, avocado, broccoli, sweet potatoes, kale, cauliflower, and tomatoes are examples of vegetables.

• Brewer's yeast, peanuts, sunflower seeds, wheat germ, royal jelly, and oatmeal are additional foods that contain vitamin B5. Although pantothenic acid is commonly found in food, processing such as canning, freezing, and milling causes it to be lost.

Fresh rather than refined foods should be consumed to provide a sufficient intake. When food is boiled, vitamin B5, like all water-soluble vitamins, is lost.

What Are the Functions of Vitamin B5?

• Pantothenic acid is an integral part of the acylation carriers, namely CoA and acyl carrier protein (ACP). The deficiency of this vitamin can be attributed to the improper functioning of coenzyme A (CoA). The tissue transport of pantothenic acid into cells is basically for the synthesis of CoA, regulated by the enzyme pantothenate kinase. CoA production does not, however, reflect the amount of available pantothenate, which makes the diagnosis of this deficiency nearly indistinguishable.

• Different forms of CoA, like acetyl CoA and succinyl CoA, are compounds important to the tricarboxylic acid cycle. The synthesis can be from fatty acids or membrane phospholipids, amino acids, steroid hormones, vitamins A and D, porphyrin, and corrin rings neurotransmitters, which are essential for life and metabolism. The acetylation and acylation of proteins and the synthesis of alpha-tubulin are also major metabolic functions of B5.

• Vitamin B5 also acts as a growth factor in metabolic cycles and is essential for various metabolic functions.

• This vitamin is also involved in the synthesis of cholesterol and lipids and also in the synthesis of certain neurotransmitters, steroid hormones, and hemoglobin.

• Vitamin B5 aids in the body's utilization of other vitamins, particularly vitamin B2, and supports a healthy digestive system. While pantothenic acid may not lessen stress, vitamin B2 does assist in regulating stress.

• Like other B vitamins, pantothenic acid aids in the body's utilization of lipids, carbohydrates, and proteins for energy production and the repair and rebuilding of tissues, muscles, and organs.

What Are the Benefits of Vitamin B5 for Skin Health?

Pantothenic acid benefits are listed below:

• Natural Moisturizer: It is a natural moisturizer that keeps the moisture on the skin.

• Assists in regulating the skin's barrier function, which increases the quantity of water that it can hold. The skin retains more water as a result of its stability. In particular, if one has dry or rough skin, utilizing a vitamin B5 serum enables the skin to retain water.

• Anti-aging Formula: Enhances the appearance of fullness and minimizes wrinkles by expanding up the outermost layer of the skin.

• Helps Healing: It promotes the healing process for chronic skin conditions. Vitamin B5's anti-inflammatory and healing qualities can aid in the healing of wounds, scars, and skin disorders like rosacea, eczema, and cystic acne. Research has indicated that it can improve the skin's ability to recover and lessen imperfections caused by acne.

What Are the Symptoms Associated With Vitamin B5 Deficiency?

Foods high in pantothenic acid are commonly found, and there are relatively few cases of vitamin B5 insufficiency documented. A pantothenic acid deficit might cause weariness or a widespread malaise, although it cannot be directly linked to any specific systemic condition.

Pantothenic acid insufficiency is most common in people who consume inadequate pantothenic acid-containing foods. People who use pantothenic acid metabolic antagonists, such as omega-methyl pantothenic acid, may also experience this. The individuals suffering from this deficiency may exhibit varying degrees of clinical signs and symptoms based on a diet such as:

• Irritability or restlessness.

• Malaise, weakness, or fatigue.

• Lack of interest in daily activities.

• Sleep cycle disorders.

• Gastrointestinal problems like nausea, vomiting, and abdominal cramps.

• Neurologic symptoms like numbness and paresthesias.

• Muscle cramps.

• Staggering gait (altered walking style).

• Hypoglycemia (low blood sugar level).

How Can Vitamin B5 Deficiency Be Managed?

Based on the recommended daily intake (RDI), which varies depending on the age group and is roughly two to five mg (milligrams) per day, a doctor or nutritionist may prescribe a patient vitamin B5. The recommended daily consumption for patients above the age of 18 is approximately five milligrams per day (mg/day). Although difficult to diagnose, vitamin B5 insufficiency can be verified with a blood or urine analysis test.

A doctor also asks about the patient's medication history because several medications, such as Azithromycin, Clarithromycin, and Erythromycin, might cause problems with the absorption of vitamin B5. These can be replaced with other medications to avoid a vitamin B5 deficit.

What Are the Side effects of Pantothenic acid?

Although pantothenic acid is taken as a supplement for several illnesses, its effectiveness in treating most of these conditions is not well-established. The use of a supplement is probably safe for those who take their vitamin B5 within the recommended daily dose, or slightly beyond it. However, anyone thinking about taking a supplement should speak with a doctor first.

Some of the pantothenic acid side effects are listed below:

• For instance, a dose as high as 10–20 grams (gm) per day could result in diarrhea. Supplemental vitamin B5 may lead to an imbalance with other B vitamins. It is therefore better to take a B complex vitamin. Take this with water, preferably after eating.

• Certain medications and vitamin B5 may interact. It might impede Azithromycin's ability to be absorbed and work as an antibiotic.

• It may not be safe for women to take more than six milligrams per day when pregnant or seven milligrams per day while nursing.

• Topical application of Dexpanthenol and Panthenol cream has been linked to incidences of allergic contact dermatitis.

• Before taking any supplements, it is always advisable to consult a doctor, especially if individuals have a medical issue beforehand or are currently on other medications.

Conclusion:

Although pantothenic acid deficiency, often known as vitamin B5, is an uncommon disorder, those who suffer from it may experience specific clinical symptoms in their gastrointestinal and neurological systems. The patient can obtain enough vitamins necessary for healthy growth and bodily functions by following a balanced diet, changing their lifestyle, or seeing a doctor or nutritionist.
