Impact of Vitamin D on Psoriasis, Sunlight Treatment, and Sources of Vitamin D
## Managing Psoriasis with Vitamin D: A Promising Approach
New research suggests that vitamin D, often referred to as the 'sunshine vitamin', could be a promising treatment for psoriasis. This essential nutrient, vital for maintaining bone, immune, and skin health, may also play a significant role in managing symptoms of psoriasis.
Recent studies indicate that vitamin D deficiency could be linked to increased severity of psoriasis, due to its influence on skin cell growth and the immune system [1][2]. Oral supplementation of vitamin D3 has shown promise in improving psoriasis symptoms, with significant reductions in Psoriasis Area Severity Index (PASI) scores observed in clinical studies [1][3].
Topical vitamin D analogues, such as calcipotriol, are also used to treat psoriasis by reducing skin cell overgrowth and inflammation [3]. Some research even suggests that applying vitamin D to the skin, especially in combination with corticosteroids, could be an effective treatment for psoriasis [5].
Individuals with psoriasis can increase their vitamin D levels through various means. Sun exposure, diet, and supplements are all viable options. Ultraviolet radiation from sunlight naturally boosts vitamin D synthesis in the skin [4]. Consuming foods rich in vitamin D, such as fatty fish, egg yolks, and fortified dairy products, can also help increase levels. Vitamin D3 supplements are recommended for managing psoriasis symptoms, especially if deficiency is confirmed [3].
The recommended doses for vitamin D supplementation vary. General recommendations suggest 600-800 IU per day, but for those with confirmed deficiencies, doses may range from 1,000 to 4,000 IU per day, under the supervision of a healthcare provider [3]. It is crucial to consult a doctor to determine the appropriate dose based on individual vitamin D levels and health status.
While the current evidence supports the use of vitamin D in psoriasis management, more research is needed to fully understand its potential benefits and optimal dosage. The National Health Service (NHS) in the UK advises that taking more than 100 micrograms (4,000 IU) of Vitamin D a day could be harmful, but a 2022 case series suggests that taking 750-1500 micrograms (30,000-60,000 IU) of vitamin D3 over a period of 2-6 months, followed by a lower daily maintenance dose could manage symptoms of psoriasis in some people [6].
In addition to vitamin D, UVB light therapy is another treatment option for psoriasis. This therapy uses UV light to slow the excessive skin cell production that psoriasis causes and may help treat the condition by slowing rapidly growing skin cells, reducing inflammation, and reducing itching [7].
Doctors may also prescribe creams containing synthetic forms of vitamin D, known as analogs, to treat psoriasis symptoms. Calcipotriene and calcitriol are common active ingredients [8]. However, it's important to note that not enough long-term clinical trials exist to show whether omega-3 fatty acid supplements are effective for treating psoriasis [9].
People with psoriasis often have low levels of vitamin D, but the reason is unclear. Factors that may contribute include poor diet, conditions that limit fat absorption, lack of sunlight, certain medical conditions, older age, higher BMI, darker skin tone, and limited sun exposure [10]. A doctor can use a blood test to check for low vitamin D levels and may advise oral supplements to increase levels if necessary.
In conclusion, vitamin D supplementation is a well-tolerated and effective adjunctive treatment for managing psoriasis symptoms. It is recommended that individuals with psoriasis consult their healthcare provider to check their vitamin D levels and determine the best course for supplementation. Combining vitamin D with other treatments, like topical creams, may enhance its benefits [5]. Always consult a healthcare professional before starting any new treatment regimen.

- It has been proposed that science might hold a promising avenue for managing skin conditions like psoriasis, as recent research indicates that vitamin D, an essential nutrient for bone, immune, and skin health, could potentially play a significant role.
- Particularly, studies suggest that vitamin D deficiency could be linked to increased severity of psoriasis due to its influence on skin cell growth and the immune system, opening up possibilities for vitamin D as a potential treatment.
- In the realm of medical-conditions, psoriasis represents one of the conditions where increasing vitamin D levels could be beneficial, with options for sun exposure, diet, supplements, and topical vitamin D analogues being viable means to achieve this.
- As part of a broader health-and-wellness approach, proper nutrition, skin care, and adherence to a doctor's advice regarding vitamin D supplementation can help maintain overall health and potentially help manage symptoms of psoriasis and other skin conditions.
