How Much Vitamin B5 for Acne?

For managing acne, studies suggest that taking high doses of Vitamin B5 (pantothenic acid), ranging from 1.5 to 10 grams per day, can be effective. This dosage should be adjusted based on individual tolerance and response, with many finding an optimal dose at about 2.5 to 5 grams daily, divided into multiple doses throughout the day. However, it’s essential to consult with a healthcare provider before starting any new supplement regimen, especially at high doses.

Vitamin B5, also known as pantothenic acid, plays a crucial role in the body, including the metabolism of proteins, fats, and carbohydrates, as well as the production of red blood cells and steroid hormones. Its role in skin health, particularly in managing acne, has gained attention due to its ability to reduce skin oiliness and inflammation, which are key factors in acne development.

Understanding the Role of Vitamin B5 in Acne Management

Vitamin B5 helps in the breakdown of oils in the form of triglycerides and cholesterol, potentially reducing the oil production in the skin that can lead to acne breakouts. It also assists in wound healing and reduces skin inflammation, making it a beneficial supplement for those struggling with acne.

Recommended Dosage and Administration

  • Starting Dosage: Beginning with a lower dose of around 500 mg to 1 gram per day and gradually increasing allows the body to adjust without significant adverse effects.
  • Optimal Dosage: Many find that a daily intake of 2.5 to 5 grams of Vitamin B5, divided into 2-4 doses, strikes a balance between efficacy and minimizing side effects. This dosage has been reported to significantly reduce acne in some individuals.
  • High Dosage: While doses up to 10 grams per day have been used in some studies and anecdotal reports, such high amounts can increase the risk of side effects and should only be considered under medical supervision.

Side Effects and Considerations

While Vitamin B5 is generally safe and well-tolerated, high doses may lead to gastrointestinal issues, such as diarrhea, or potentially interfere with the absorption of other B vitamins. It is crucial to monitor your body’s response and adjust the dosage as necessary.

Additional Tips for Acne Management

Incorporating Vitamin B5 should be part of a comprehensive approach to acne, which includes:

  • Topical Treatments: Using products containing salicylic acid, benzoyl peroxide, or retinoids can complement the effects of Vitamin B5.
  • Diet and Hydration: A well-balanced diet rich in fruits, vegetables, and adequate water intake can support skin health.
  • Stress Management: Stress can exacerbate acne, so incorporating stress-reduction techniques like exercise, meditation, or yoga can be beneficial.


Vitamin B5 has shown promise in managing acne, with an effective range typically between 1.5 to 10 grams per day, tailored to individual tolerance and response. It’s important to approach its use cautiously, starting with lower doses and considering the potential for side effects. Always consult a healthcare provider before beginning any new supplement, particularly at high dosages, to ensure it is appropriate for your health condition and does not interfere with other medications or supplements you may be taking. With the right approach, Vitamin B5 can be a valuable part of acne treatment and skin health maintenance.
