What is Vitamin B5 (Pantothenic Acid)?

Vitamin B5, commonly known as pantothenic acid, is a water-soluble B vitamin that plays a vital role in numerous bodily functions. The name "pantothenic" comes from the Greek word "pantothen," meaning "from everywhere," reflecting its widespread presence in many foods.

Pantothenic acid is a key component of coenzyme A (CoA), which is essential for numerous chemical reactions in the body, particularly those involved in the metabolism of carbohydrates, proteins, and fats. It's also important for the production of hormones and cholesterol, as well as the maintenance of healthy skin.

Health Benefits of Vitamin B5

Energy Production

As a component of coenzyme A, pantothenic acid is crucial for converting food into energy. It helps break down fats, carbohydrates, and proteins so they can be used for energy production in the body's cells. Without adequate pantothenic acid, the body's energy production systems would be significantly impaired.

Stress Response

Vitamin B5 is sometimes referred to as the "anti-stress vitamin" because it supports the adrenal glands and helps in the production of stress hormones. The adrenal glands rely on pantothenic acid to produce cortisol and other hormones that help the body respond appropriately to stress.

Skin Health

Pantothenic acid plays a key role in maintaining skin health. It helps in the formation of skin cells and contributes to the barrier function of the skin. Some research suggests that pantothenic acid may help reduce acne and promote wound healing. It's also used in various skin care products for its moisturizing properties.

Cholesterol and Triglyceride Regulation

Through its role in coenzyme A, pantothenic acid is involved in the synthesis and metabolism of cholesterol and triglycerides. It helps maintain healthy lipid levels in the body, which is important for cardiovascular health.

Signs of Vitamin B5 Deficiency

True pantothenic acid deficiency is rare because this vitamin is found in so many foods. However, signs of deficiency can include:

Fatigue and widespread weakness
Irritability and restlessness
Digestive problems, including nausea and abdominal cramps
Numbness and tingling in hands and feet (paresthesia)
Headaches
Muscle cramps
Increased susceptibility to infections

In experimental settings, pantothenic acid deficiency has been associated with "burning feet syndrome," characterized by painful burning sensations in the feet.

Food Sources of Vitamin B5

Pantothenic acid is widely distributed in foods, hence its name. Good dietary sources include:

Food	Pantothenic Acid Content (mg)	% of Daily Value
Beef liver (3 oz, cooked)	5.6	112%
Shiitake mushrooms (1/2 cup, cooked)	2.6	52%
Sunflower seeds (1/4 cup)	2.4	48%
Chicken breast (3 oz, roasted)	1.3	26%
Avocado (1 whole)	2.1	42%
Eggs (1 large)	0.7	14%

Recommended Intake

The Adequate Intake (AI) for pantothenic acid is:

Age Group	Males (mg/day)	Females (mg/day)
1-3 years	2	2
4-8 years	3	3
9-13 years	4	4
14-18 years	5	5
19+ years	5	5
Pregnant women	-	6
Breastfeeding women	-	7

Supplementation Considerations

While pantothenic acid deficiency is rare, supplementation may be beneficial in certain situations:

Individuals with digestive disorders that affect nutrient absorption
People using pantothenic acid for its potential benefits in reducing acne
Athletes and physically active individuals who may have increased pantothenic acid requirements
People experiencing high levels of stress

When considering supplementation, it's important to consult with a healthcare provider, who can provide personalized recommendations based on your specific health needs.

Important Note:

Pantothenic acid is generally considered safe, even at high doses. However, very high doses (several grams per day) may cause digestive upset or diarrhea. As with any supplement, it's best to follow recommended dosages and consult a healthcare provider before starting supplementation.
