Association Between Vitamin D Levels & Alopecia Areata

AE 14A recent study out of Turkey found that in those with alopecia areata, low vitamin D levels are common and may relate to a more severe disease state.

Vitamin D has a well-established effect on the immune system and is linked to a variety of autoimmune diseases. Researchers have found that vitamin D may be able to help in some aspects of autoimmune diseases, such as multiple sclerosis, lupus, and type 1 diabetes. That being said, there hasn’t been any research looking at the relationship between vitamin D and AA.

Recently, researchers at the Şişli Etfal Eğitim ve Araştırma Hastanesi (Training and Research Hospital) in Turkey conducted a study to determine if vitamin D levels relate to AA and how vitamin D may affect disease severity.

They wanted to know how vitamin D levels differed between the three groups and how vitamin D levels related to disease severity in those with AA and vitiligo.

The researchers found that 90.7% of patients with AA had vitamin D levels at or less than 20 ng/ml compared to 70.5% of patients with vitiligo and 32.8% of the healthy participants. Furthermore, they found that lower vitamin D levels were significantly related to an increased percentage of hair loss on the scalp, but they found no significant relationship between vitamin D levels and BSA in vitiligo.

“We found that [vitamin D] levels were significantly lower in patients with AA than in patients with vitiligo and in healthy controls,” the researchers stated.

“In addition, our results show that there is a significant inverse correlation between low [vitamin D] levels and severity of AA according to SALT scores.”

    I had alopecia and lost all my hair, vitamin D was below 20 for years. I now have vitamin D in the 20s and hair is coming back, not enough to go in public but getting closer! I don’t know if it was vitamin D, but I believe it has something to do with it. I now take 5000IU OF D3 daily
