What Is B5 Aka Pantothenic Acid?

Vitamin B5, also known as pantothenic acid, is one of the B-complex vitamins that are essential for various bodily functions. It is a water-soluble vitamin, which means it is not stored in the body and needs to be consumed regularly through the diet. It is naturally present in various foods, can be added to food products, and is available in supplement form. This essential nutrient plays a crucial role in the production of coenzyme A (CoA), which supports enzymes in both the creation and breakdown of fatty acids, as well as other vital metabolic processes. Additionally, vitamin B5 contributes to the formation of the acyl carrier protein, which is also involved in the synthesis of fats.

For those seeking comprehensive information about vitamin B5, the following details provide a closer look at its essential functions and dietary sources.

What Are The Functions ?

Vitamin B5 plays several vital roles in the body, including:

  1. Energy Metabolism: Vitamin B5 is a crucial component of coenzyme A (CoA), which is involved in the breakdown of carbohydrates, fats, and proteins for energy production.
  2. Fatty Acid Synthesis: Coenzyme A, derived from pantothenic acid, also plays a role in the synthesis of fatty acids, which are essential for the formation of cell membranes and various cellular processes.
  3. Stress Hormone Production: Pantothenic acid is required for the synthesis of stress hormones, including cortisol and adrenaline, which are released in response to stressful situations.
  4. Skin Health: Some skin care products include derivatives of pantothenic acid, such as panthenol (provitamin B5), which can help maintain healthy skin and hair.
  5. Nervous System Support: Pantothenic acid is involved in the production of neurotransmitters, which are vital for proper nervous system function.

How Much Vitamin Do I Need? What Are The Recommended Amounts?

RDA: For men and women who are 19 years of age or older, the Recommended Dietary Allowance (RDA) is 5 mg per day. The dosage rises to 6 mg and 7 mg daily for pregnancy and nursing, respectively.

UL: The Tolerable Upper Intake Level (UL) represents the maximum daily dose unlikely to result in adverse effects for the general population. As there is no observed toxic level associated with high pantothenic acid intake, a specific UL has not been established for this nutrient.

What Happens If There Is Excess Of Pantothenic?

There is not enough data to determine the potential effects of taking supplements containing high doses of pantothenic acid daily.

What Are The Food Sources Of Pantothenic Acid?

food sources of vitamin b5

A wide range of foods contains pantothenic acid, making it readily accessible in the diet. While some pantothenic acid can be produced by gut bacteria, the quantities generated are generally insufficient to fulfill the body’s nutritional requirements.

Almost all vegetables, wholegrain foods, and meats contain varying amounts of pantothenic acid, but the following are some excellent sources:

  • Chicken/Beef
  • kidneys and the liver
  • Eggs
  • Mushrooms
  • Avocado

Those breakfast cereals that have been fortified with pantothenic acid are likewise a healthy source.

Deficiency : The Possible Disorders And Their Symptoms

Pantothenic acid is abundant in a wide range of foods, which means that a deficiency in pantothenic acid is typically uncommon, and it is most likely to occur in individuals who are severely malnourished or those with additional nutrient deficiencies. In rare instances, individuals with specific genetic mutations may face circumstances where they have difficulty digesting pantothenic acid.


Deficiency signs may include:

  • Headache
  • Fatigue
  • Irritability, restlessness
  • Disturbed sleep
  • Nausea, vomiting, stomach cramps
  • Numbness or burning sensation in hands or feet
  • Muscle cramps

Toxicity In Case Of Excess Of Vitamin B5 Aka Pantothenic Acid

in very rare instances of extremely high doses (typically well above the recommended daily intake), there have been reports of mild side effects, such as diarrhea and stomach discomfort. These effects are usually temporary and subside once the excess intake of pantothenic acid is discontinued.

It’s important to note that for the vast majority of people, consuming pantothenic acid from a balanced diet or standard vitamin B-complex supplements is not associated with any adverse effects. As with any nutrient, it’s best to follow recommended daily intake guidelines and consult with a healthcare professional before taking high-dose supplements, as excessive intake of any nutrient can potentially have unintended consequences.
