Vitamin D is a fat-soluble vitamin which is naturally produced in the body when sunrays convert the skin’s chemicals into Vitamin D. The vitamin is very important for the health of bones, muscles, teeth and hair, and it also plays its role in the prevention of different diseases, some of which are Diabetes, Hypertension, and Stroke. Little to no sun exposure can lead to Vitamin D deficiency.
Effect of Vitamin D on Hair Loss
There are many diseases such as; thyroid dysfunction, diabetes, and lupus, which can increase hair loss. Sufficient amounts of Vitamin D play an important role in preventing these diseases, which in turn reduces hair loss. If you lack the vitamin, it may lead to hair shedding. Hair shedding is normal if a person sheds about 100 hairs per day. However, if a person sheds 200 to 300 hairs per day, this could indicate a potential medical disorder.
Daily Dietary Intake and Vitamin D Supplementation
The daily dietary intake should be up to 15mcg or 600 IU per day. Foods with great amounts of the vitamin include; blue fish, catfish, cod liver oil, egg yolk, and milk.
Other good sources are mushrooms, oysters, salmon, shrimp, tuna, and sardines. Fish is an excellent source because it contains omega-3 which is part of the Vitamin D production process. If the dietary intake and sun exposure is not enough to cover the vitamin deficiency, then supplements may be able to help. However, it is important not to consume more than the recommended dose as it can lead to several side effects including loss of appetite, nausea, vomiting, constipation, increased heart beat, muscular weakness, and constipation.
