Vitamin D
Many of the studies in the review found low levels of vitamin D in people with alopecia areata. Alopecia areata is an autoimmune condition.
There is also little evidence to suggest that vitamin D can lead to hair regrowth. However, further studies are necessary to confirm this potential link. Vitamin D supplements are available for purchase online, but a person should always check with their doctor before taking any vitamins.
An excessively high dose would be over 50,000 IU or when blood levels of vitamin D are greater than 150 ng/ml . Cases of vitamin D toxicity are typically related to inappropriate dosing. To prevent problems, a person should ask their doctor to test their vitamin D levels and suggest a suitable dosage.
