What is Vitamin B5 (Pantothenic acid)?

Vitamin B5, also known as pantothenic acid, is a water-soluble vitamin that is essential for the production of coenzyme A and the metabolism of fats, proteins, and carbohydrates.

What are the mechanisms by which it works for medicinal purposes?

Vitamin B5 is required for the synthesis of coenzyme A, which plays a critical role in energy metabolism. It also plays a role in the synthesis of fatty acids, cholesterol, and steroid hormones.

What are the active ingredients that are important for its medicinal properties?

The active ingredient in vitamin B5 is pantothenic acid.

What forms does it come in?

Vitamin B5 is available in supplement form as well as in a variety of foods.

When was it first used for medicinal purposes?

Vitamin B5 was first discovered and isolated in 1933, and it was first used for medicinal purposes in the 1940s.

What if there’s an imbalance or deficiency?

A deficiency in vitamin B5 can cause a number of symptoms, including fatigue, insomnia, depression, irritability, stomach pain, and vomiting.

Summary:

Vitamin B5 is an essential nutrient that plays a critical role in a variety of bodily functions. It has been shown to be effective in treating a number of conditions, including acne and wound healing, and it may help prevent a number of age-related conditions. Vitamin B5 is generally well-tolerated and has no known side effects at recommended doses.

What does Vitamin B5 (Pantothenic acid) help with?

Vitamin B5 is also called pantothenic acid. It turns up in many foods, such as eggs, meat, whole grains and avocado. Your body uses it to build coenzyme A, a helper molecule used in many cell jobs.

A true shortage of B5 is rare on a mixed diet. Most claims for B5 pills rest on body chemistry, lab work, or small human studies. The best human evidence is for high-dose B5 in acne, and for skin creams that contain panthenol.

• Acne and oily skin
  Good evidence — several clinical trials of daily high-dose B5, sizes and doses not on file here. Several clinical trials reported fewer acne spots with daily high-dose B5. Researchers think high doses may cut skin oil by helping the skin handle fatty acids; that is a proposed mechanism, not a proven one. The exact doses and trial sizes are not on file in this library.
  Evidence grade B · Traditional tier T0
• High cholesterol and high triglycerides
  Early evidence — human studies of pantethine, a B5 derivative; sizes and doses not on file. Pantethine is a form made from B5, and it has been studied for blood fats. Those studies reported lower LDL cholesterol and lower triglycerides, with a small rise in HDL. Lab work points to the liver making less fat and cholesterol. Plain B5 is not the same thing as pantethine.
  Evidence grade C · Traditional tier T0
• Wounds, grazes and skin repair after a procedure
  Early evidence — clinical use and studies of topical panthenol; trial sizes not on file. Panthenol is the form of B5 that goes on the skin. It is widely used in wound care and after skin treatments. Studies report faster repair, less redness and better moisture, but trial sizes are not on file here.
  Evidence grade C · Traditional tier T0
• Morning stiffness and sore joints in rheumatoid arthritis
  Early evidence — early human research; sizes and doses not on file. Some research found lower blood B5 levels in people with rheumatoid arthritis. In that work, supplements were linked with less morning stiffness and joint pain. The research is early, and B5 was studied as an add-on to regular care.
  Evidence grade C · Traditional tier T0
• Tingling, burning feet and mild nerve pain
  Evidence doesn't support this — a few small human reports, no trial details on file. Some people with burning feet or mild nerve trouble reported feeling better while taking B5. These reports are few, and the numbers are not on file. B5 is known to be used in making myelin, the coating on nerve fibres, but that is basic biology rather than trial proof.
  Evidence grade D · Traditional tier T0
• Low energy and feeling tired
  Not yet tested in people — no human trial on file; general nutrition science only. B5 is well established as part of how cells turn food into fuel. That is standard nutrition science, not a test of B5 pills. No human trial on file has checked whether extra B5 lifts energy in people who already get enough.
  Evidence grade insufficient · Traditional tier T0
• Stress and so-called adrenal fatigue
  Not yet tested in people — body chemistry only; no human study on file. The adrenal glands are known to use B5 when they make cortisol. That is textbook biochemistry, not a study of supplements. No human study on file has tested B5 for long-term stress or for adrenal fatigue.
  Evidence grade insufficient · Traditional tier T0
• Recovery after hard exercise
  Not yet tested in people — reasoning from B5's role in energy chemistry; no human trial on file. B5 is known to sit at the centre of energy and fat use in cells. That is general biology, not a training study. No human trial on file has looked at B5 for muscle soreness, stamina or recovery between sessions.
  Evidence grade insufficient · Traditional tier T0
• Hormone balance
  Not yet tested in people — biochemistry only; no human study on file. Sex hormones such as testosterone, oestrogen and progesterone are built with coenzyme A, which the body makes from B5. That link is basic biochemistry. No human study on file has tested B5 pills for hormone balance or hormone symptoms.
  Evidence grade insufficient · Traditional tier T0

What Vitamin B5 (Pantothenic acid) has not been shown to do

• No human trial on file shows that B5 pills raise energy in people who already get enough from food.
• B5 has not been shown in any human study on file to correct adrenal fatigue or reduce stress.
• No study on file shows that B5 speeds muscle recovery or eases soreness after training.
• B5 has not been shown to balance testosterone, oestrogen or progesterone in people.
• B5 has not been shown to replace standard treatment for rheumatoid arthritis; it was studied only alongside regular care.
• Plain B5 tablets have not been shown to lower blood fats the way pantethine did in its own studies.
• The wound results come from panthenol put on the skin; swallowing B5 has not been shown to do the same.

How to read this:

A is the strongest grade: several matching human trials. B means at least one good human trial. C means small or early human studies. D means the human evidence is weak or mixed. Insufficient means no human study on file, only lab work, body chemistry or custom. This page reports what studies found. It is not advice, not a promise of results, and not a reason to stop any treatment. Talk to your own clinician before starting high-dose supplements.

What can Vitamin B5 (Pantothenic acid) help prevent?

• Pantothenic acid deficiency (essential for normal cellular function — prevents the fatigue, numbness, and irritability that come with inadequate intake)
• Worsening of stress-related adrenal burnout (supports sustained cortisol production during prolonged stress periods)
• Progression of hyperlipidemia (pantethine form has documented cholesterol-lowering effects that may reduce cardiovascular risk over time)

Which foods are rich in it?

Foods that are rich in Vitamin B5 include:

• organ meats
• mushrooms
• avocado
• sweet potatoes
