Reviewed on 9 Mar 2026

Vitamin B5, also known as Pantothenic Acid, is essential for synthesizing coenzyme A, crucial in fatty acid metabolism. Human evidence for supplementation benefits is limited.

Clinical Dose

Dose range varies by context and product formulation.

Best Form

Look for: Look for a standardized Vitamin B5 form with transparent potency labeling.

How it works

Vitamin B5 is a precursor to coenzyme A, which is vital for the synthesis and oxidation of fatty acids and the Krebs cycle, a key energy production pathway. It also plays a role in synthesizing cholesterol, steroid hormones, and neurotransmitters. The exact mechanism of its benefits in supplementation is not well-established.

Who should take it

Individuals with a diagnosed deficiency or those with specific metabolic disorders as advised by a healthcare provider.

Who should avoid it

Generally safe, but those with known hypersensitivity to vitamin B5 should avoid. Pregnant and breastfeeding women should consult a doctor before use.

Side effects

Mild side effects like diarrhea are rare and typically occur only at very high doses.

Common forms

Pantothenic Acid

Calcium D-Pantothenate

Vitamin B5 (Pantothenic Acid)

D-Pantothenate

What the research says

Human clinical trials on vitamin B5 supplementation are scarce. Some studies suggest potential benefits for acne treatment, but results are inconsistent. Typical doses in studies range from 2 to 10 grams per day for acne, but such high doses are not recommended without medical supervision. There is a lack of robust evidence supporting other health claims.

In depth: Vitamin B5

Vitamin B5, or Pantothenic Acid, is a water-soluble B vitamin crucial for human metabolism and energy production. It is a precursor to coenzyme A (CoA), a key molecule involved in the synthesis and oxidation of fatty acids, the Krebs cycle, and the metabolism of carbohydrates and proteins. Indians often use Vitamin B5 supplements to support energy levels, skin health, and stress management. While it is widely available in dietary sources like eggs, meat, whole grains, and legumes, supplementation is sometimes considered due to its role in enhancing metabolic efficiency. However, scientific evidence supporting its benefits beyond preventing deficiency is limited. Most studies focus on its role in treating acne, with mixed results, and there is a lack of robust clinical trials for other purported benefits. Dietary sources are generally sufficient for maintaining adequate levels, but certain lifestyles or dietary restrictions may necessitate supplementation.

Key benefits

✓Energy metabolism: Supports the synthesis of coenzyme A, crucial for energy production (Strong evidence for preventing deficiency).
✓Skin health: May help in reducing acne, although evidence is inconsistent (Moderate evidence).
✓Stress management: Plays a role in the synthesis of stress-related hormones, but evidence is limited (Weak evidence).
✓Cholesterol management: May help in lowering LDL cholesterol, but more research is needed (Insufficient evidence).
✓Wound healing: Supports the healing process due to its role in cellular repair (Insufficient evidence).

How to take it

The optimal dose of Vitamin B5 varies depending on individual needs and health goals. For general health maintenance, doses between 5-10 mg are typically sufficient, as these levels are easily obtained through a balanced diet. For specific conditions like acne, studies have used doses ranging from 2 to 10 grams per day, but such high doses should only be taken under medical supervision due to potential side effects. It is generally recommended to take Vitamin B5 with food to enhance absorption and minimize gastrointestinal discomfort. There is no specific cycling requirement, but long-term high-dose supplementation is not advised without medical guidance. Vitamin B5 can be stacked with other B vitamins for synergistic effects, particularly in B-complex formulations. In India, typical supplement sizes range from 100 mg to 500 mg per capsule, with costs varying from ₹200 to ₹1500 for a month's supply, depending on the brand and dosage.

Forms compared

Calcium Pantothenate

The most common form in supplements, it is highly stable and well-absorbed. It is often used in B-complex formulations and is widely available in India.

Pantethine

A derivative of Vitamin B5, it is sometimes used for cholesterol management. It is less common in Indian markets and generally more expensive.

D-Pantothenic Acid

The pure form of Vitamin B5, it is less commonly used in supplements due to its instability. It is rarely found in Indian supplement products.

Safety & interactions

Vitamin B5 is generally considered safe for most people when taken in recommended doses. It has a low toxicity profile, and there are no known serious side effects at standard doses. However, high doses (2-10 grams per day) may cause diarrhea, nausea, and heartburn. Individuals with hemophilia or who are taking blood-thinning medications should consult a healthcare provider before supplementation, as Vitamin B5 may increase bleeding risk. There are no known interactions with common Indian prescriptions like metformin, statins, or thyroid medications, but caution is advised. The upper tolerable limit is set at 1,000 mg per day for adults, but this is based on limited data. Long-term use of high doses has not been thoroughly studied, so it is prudent to avoid excessive supplementation without medical supervision.

India context

Vitamin B5 deficiency is rare in India due to its widespread availability in common foods. However, individuals with restrictive diets, such as vegetarians or those with limited access to diverse food sources, may be at higher risk. The regulatory status of Vitamin B5 in India is governed by the Food Safety and Standards Authority of India (FSSAI), which ensures basic safety and labeling standards. Common adulterants or red flags in the Indian market include products with misleading claims or insufficient active ingredients. Quality supplements typically cost between ₹200 to ₹1500 for a month's supply, depending on the brand and dosage. Active individuals, athletes, and those with high-stress lifestyles may benefit most from supplementation.

Buying guide

When purchasing Vitamin B5 supplements, look for products that clearly state the amount of Pantothenic Acid per serving. Prefer supplements that have been certified by the FSSAI, as this ensures basic safety and quality standards. For added assurance, consider products with additional certifications like NSF or Informed Sport, which indicate rigorous testing for contaminants. Be cautious of products with proprietary blends or proprietary ingredients, as these may obscure the actual amount of Vitamin B5. Read the ingredient list to ensure there are no unnecessary fillers or artificial colors. Opt for reputable brands with transparent labeling and positive customer reviews. Avoid products that make exaggerated health claims without scientific backing.

Bottom line

Vitamin B5 is a safe and essential nutrient for maintaining overall health, particularly for energy metabolism and skin health. While dietary sources are usually sufficient, supplementation may benefit specific groups like vegetarians or those with acne. For general use, a daily dose of 5-10 mg is recommended, while higher doses should be taken under medical supervision. Calcium Pantothenate is the most common and effective form available in India. Choose products with clear labels and reputable certifications to ensure quality and safety.
