Vitamin B5 (Pantothenic Acid): 7 Benefits for Energy, Skin and Stress Management

Vitamin B5, also known as pantothenic acid, is a water-soluble B vitamin that the body cannot store in large amounts, so it must be obtained daily from food or supplements. This vitamin is involved in energy production, helps maintain healthy skin and hair, contributes to the production of stress hormones and normal nervous system function. In this article you will learn what benefits vitamin B5 can bring to your health, which foods are richest in it, how to take it safely and what to look for when choosing supplements.

What Is Vitamin B5 (Pantothenic Acid) and Why Is It Important?

Vitamin B5 is a water-soluble vitamin belonging to the B vitamin family, and it is known by two names – vitamin B5 and pantothenic acid. The name pantothenic acid comes from the Greek word “pantos”, meaning “everywhere”, because this vitamin is naturally found in almost all foods.

In the body, vitamin B5 is converted into coenzyme A (CoA) – one of the most important molecules in cellular metabolism. Coenzyme A participates in more than a hundred biochemical reactions related to energy production, fatty acid oxidation, the synthesis of cholesterol and hormones, and the production of neurotransmitters.

Because vitamin B5 is water-soluble, the body cannot store it in large amounts – the excess is removed through urine. This means that pantothenic acid reserves must be replenished regularly, and a deficiency, although rare, can manifest as fatigue, skin problems, hair loss and irritability.

This vitamin is especially important for tissues that divide rapidly and use a lot of energy – the skin, hair, nerves and adrenal glands. For this reason, vitamin B5 is an integral part of a balanced diet, and an adequate amount is particularly important for active people and those who experience a lot of stress.

Vitamin B5 Helps Convert Food into Energy

One of the main functions of vitamin B5 is to help the body convert food into energy. Pantothenic acid is a component of coenzyme A (CoA), and coenzyme A participates in the so-called citric acid cycle – the process by which cells produce adenosine triphosphate (ATP), the main source of cellular energy.

Without an adequate amount of vitamin B5, this energy production process slows down, which can lead to fatigue, reduced physical performance and poorer concentration. This is especially relevant for people who consume a lot of carbohydrates and fats – athletes, physically active individuals and those whose diet is dominated by fast food.

The European Food Safety Authority (EFSA) has confirmed that pantothenic acid contributes to normal energy metabolism and reduces tiredness and fatigue. This means that an adequate amount of vitamin B5 helps maintain normal energy levels throughout the day.

It is worth noting that vitamin B5 works together with other B vitamins – they all participate in the energy production chain and complement each other. For this reason, complex B vitamin supplements are often a more convenient choice than pantothenic acid alone.

Vitamin B5 Supports the Production of Stress Hormones

Vitamin B5 is often called the “anti-stress vitamin” because it is essential for adrenal gland function and the production of stress hormones – cortisol and adrenaline. The adrenal glands are small glands located above the kidneys that produce hormones helping the body respond to stress.

When experiencing stress, the adrenal glands use more pantothenic acid to produce the required amount of cortisol. During prolonged stress, the need for vitamin B5 may increase, and its deficiency can contribute to adrenal exhaustion, fatigue, irritability and a poor stress response.

The European Food Safety Authority has confirmed that pantothenic acid contributes to normal steroid hormone synthesis. Steroid hormones – cortisol, aldosterone and sex hormones – are responsible for the body’s stress response, fluid balance and overall well-being.

If you feel that stress has exhausted you and your energy is decreasing, it is worth considering a higher amount of B vitamins in your diet or supplements. Vitamin B5 is often recommended in combination with magnesium, which is also important for nervous system calm and stress management.

Vitamin B5 Supports Skin Health and Wound Healing

Vitamin B5 plays an important role in maintaining healthy skin. Pantothenic acid helps cells divide and renew, which is especially important for the skin, which constantly renews itself and must heal from daily micro-damage.

A form of pantothenic acid called panthenol (provitamin B5) is widely used in cosmetics and skin care products – creams, lotions and ointments. Panthenol helps moisturize the skin, reduce irritation and promote wound healing, which is why it is often added to products for sunburn, scratches and dry skin.

Vitamin B5 deficiency can manifest as dry, flaky skin, skin rashes and slower wound healing. An adequate amount of pantothenic acid helps maintain the skin barrier, which protects the body from external irritants and moisture loss.

If your skin tends to be dry and irritated, it is worth considering a higher amount of B vitamins in your diet. Vitamin B5 pairs well with biotin, which is also important for the health of skin, hair and nails.

Vitamin B5 Supports Hair Health

Vitamin B5 is one of the vitamins most commonly associated with hair health. Pantothenic acid helps hair follicles receive enough energy, which is essential for normal hair growth and strength.

Panthenol, a form of provitamin B5, is often added to shampoos and conditioners because it helps moisturize the hair, reduce breakage and give it shine. Panthenol penetrates the hair shaft, retains moisture and makes the hair more elastic and less prone to breakage.

Although scientific evidence that vitamin B5 directly stops hair loss is limited, its deficiency can contribute to hair weakness and poorer hair condition. An adequate amount of pantothenic acid helps maintain a healthy hair growth cycle.

If you want to take care of your hair from within, it is best to choose a complex B vitamin supplement in which vitamin B5 is combined with biotin and vitamin B12 – these vitamins together support hair and scalp health.

Vitamin B5 Supports Nervous System Function

Vitamin B5 contributes to normal nervous system function. Nerve cells use a lot of energy, and pantothenic acid participates in the energy production processes on which nerve impulse transmission and brain activity depend.

Coenzyme A, which contains vitamin B5, is essential for the synthesis of acetylcholine – an important neurotransmitter responsible for memory, learning and muscle control. An adequate amount of pantothenic acid helps maintain normal brain function and mental clarity.

The European Food Safety Authority has confirmed that pantothenic acid contributes to normal mental performance. This means that an adequate amount of vitamin B5 helps maintain concentration, memory and good mood.

Vitamin B5 is closely related to other B vitamins, such as vitamin B6 and vitamin B12, which are also important for the nervous system. Together these vitamins participate in the production of neurotransmitters and the protection of nerve cells.

Vitamin B5 Helps Metabolize Fats and Synthesize Cholesterol

Vitamin B5 plays an important role in fat metabolism. Coenzyme A, which contains pantothenic acid, is essential for fatty acid oxidation – the process by which fats are converted into energy.

Without coenzyme A, the body could not efficiently use stored fat for energy, which is important for both weight management and physical performance. Pantothenic acid is also essential for the synthesis of cholesterol – the substance from which all steroid hormones and cell membranes are made.

Cholesterol is often wrongly considered a purely negative substance, but in fact it is essential for cell structure and hormone production. Vitamin B5 helps maintain normal cholesterol synthesis, which is a vital bodily function.

According to the U.S. National Institutes of Health (NIH), pantothenic acid is essential for the synthesis and breakdown of fatty acids, which confirms its importance for normal metabolism.

Vitamin B5 Helps Synthesize Hormones and Vitamin D

Vitamin B5 participates in the synthesis of steroid hormones – cortisol, aldosterone, testosterone and estrogens. All of these hormones are produced from cholesterol, and coenzyme A is essential at every step of this synthesis.

Pantothenic acid is also important for vitamin D synthesis in skin cells. Vitamin D is a steroid-structured compound whose synthesis requires coenzyme A, so an adequate amount of vitamin B5 indirectly contributes to normal vitamin D production.

The European Food Safety Authority has confirmed that pantothenic acid contributes to the normal synthesis and metabolism of steroid hormones, vitamin D and some neurotransmitters. This is one of the broadest functions of vitamin B5, covering both hormonal balance and mood.

Hormonal balance is important for overall well-being, energy, sleep and even weight management. An adequate amount of vitamin B5, together with a balanced diet, helps maintain normal hormone production and overall body balance.

How to Take Vitamin B5: Dosage, Timing and Duration

The recommended daily amount of vitamin B5 for adults is 5 milligrams per day. Pregnant women are recommended 6 milligrams, and breastfeeding women – 7 milligrams per day. This amount is usually easily obtained from a balanced diet.

Vitamin B5 is best taken in the morning or during the day, with food, because food helps absorb this vitamin better and avoid possible stomach discomfort. Since pantothenic acid is involved in energy production, taking it in the morning helps maintain energy levels throughout the day.

Vitamin B5 can be taken long-term and regularly because it does not accumulate in the body and the excess is removed through urine. It is advisable to take supplements at the same time every day to establish a consistent habit.

An upper safe limit for vitamin B5 has not been established, because even very large doses are usually well tolerated. Doses several dozen times higher have been used in studies, but they should only be taken after consulting a doctor. For everyday needs, a B vitamin complex in which pantothenic acid is combined with other B vitamins is sufficient.

Vitamin B5 Side Effects and Safety

Vitamin B5 is one of the safest vitamins, and side effects are very rare. Because pantothenic acid is water-soluble, the body removes the excess through urine, so overdosing through daily use is practically impossible.

Very large doses of vitamin B5 – over 10 grams per day – can cause diarrhea, nausea or heartburn, but such doses are used only in special cases and only under medical supervision. Normal supplement doses do not cause side effects.

Despite its safety, before starting to take any supplements it is worth consulting a doctor, especially if you take medication or have chronic conditions. This is important for pregnant and breastfeeding women, even though they need higher amounts of vitamin B5.

It is worth knowing that pantothenic acid can interact with some medications – for example, the antibiotic tetracycline, whose absorption vitamin B5 can reduce, so it is advisable to separate their intake by a few hours.

Vitamin B5 in the Diet: Best Food Sources

Vitamin B5 is found in almost all foods, so deficiency in healthy people eating a balanced diet is very rare. The richest sources are animal products, but it is also abundant in plant foods.

Here are the foods richest in vitamin B5:

• Liver and organ meats – one of the most concentrated sources of pantothenic acid.
• Eggs – especially egg yolks, which are rich in vitamin B5.
• Avocados – one of the best plant sources of pantothenic acid.
• Mushrooms – especially shiitake and white button mushrooms.
• Sunflower seeds – a good plant source and a convenient snack.
• Whole-grain products – oats, brown bread and whole-grain pasta.

It is worth remembering that vitamin B5 is sensitive to heat – cooking food at high temperatures destroys part of the pantothenic acid. Therefore, it is worth combining cooked and fresh food, and vegetables are best prepared briefly, steamed or eaten raw.
