Vitamin D and Acne: Studies, Advantages, and Dosage Recommendations
Vitamin D, a nutrient known for its role in bone health, may also have a connection to acne treatment. However, the scientific consensus regarding its effectiveness is still evolving.
In the United States, vitamin D deficiency is prevalent among adults, particularly among African-American and Mexican-American individuals [1]. A 2014 study found that people with acne had significantly lower vitamin D levels than those without acne [2]. This association has led researchers to explore the potential benefits of vitamin D supplementation for acne treatment.
One theory suggests that vitamin D's role in immune regulation and skin repair could be beneficial in managing acne [5]. Deficiencies in vitamin D have been linked to inflammatory skin conditions, providing a plausible explanation for the potential benefits of supplementation. However, it's important to note that the current scientific literature does not include direct clinical trials or meta-analyses conclusively demonstrating that vitamin D supplements reduce acne severity or frequency [5].
Some studies have focused on topical applications of vitamin D. For instance, a study of 48 female medical students compared the effects of a topical vitamin D cream with an aloe vera-based placebo [6]. While the study found that topical vitamin D increased vitamin D levels, the effectiveness of topical vitamin D for acne treatment was not discussed [6].
Other studies have investigated the potential anti-inflammatory benefits of vitamin D supplements. A 2020 study found that a vitamin D supplement called alfacalcidol reduced inflammation and increased vitamin D levels, potentially playing a role in acne management and treatment [7].
Despite these findings, it remains unclear whether people without a vitamin D deficiency would benefit from taking supplements. It's also worth noting that some evidence suggests that sunlight may treat acne, but the data is inconclusive [5].
In summary, while the potential benefits of vitamin D in acne treatment are biologically plausible, the current scientific literature lacks definitive clinical proof of its effectiveness. Individuals considering vitamin D supplementation for acne should consult healthcare professionals, and further robust clinical research is warranted to establish clear therapeutic guidelines.
It's also important to remember that acne occurs when follicles in the skin become blocked and can become inflamed and infected [3]. Androgens and bacteria contribute to the inflammation and swelling in the skin. Lesions caused by acne can cause skin infections, scarring, and long-term skin damage, with severe cases causing keloid scarring or hyperpigmentation, particularly among people with darker skin [4].
In addition to supplements, other sources of vitamin D include foods naturally high in vitamin D, such as tuna, beef liver, and egg yolks, as well as foods supplemented with vitamin D, such as milk, yogurt, and cereals [8]. Always check with a doctor before taking vitamin D supplements. A doctor can measure vitamin D levels to detect possible deficiencies.

- Although the scientific consensus on the effectiveness of vitamin D supplementation for acne treatment is still evolving, its potential benefits are biologically plausible considering its role in immune regulation and skin repair, and the link between deficiencies in vitamin D and inflammatory skin conditions.
- In addition to exploring supplementation, some studies have focused on topical applications of vitamin D, but the effectiveness of these for acne treatment remains unclear.
- Beyond supplements and topical applications, foods that are naturally high in vitamin D, such as tuna, beef liver, and egg yolks, or foods supplemented with vitamin D, such as milk, yogurt, and cereals, serve as alternative sources to ensure adequate nutrition and potentially contribute to overall health-and-wellness, skin-care, and nutrition.
