Dietary deficiencies may cause hair loss. So, vitamin D deficiency has been linked to increased risk of hair loss. That’s way, sun exposure and intake of vitamin D supplements may be good for your hair!
Daily needs of vitamin D
Most people need a daily dose of 600 IU of vitamin D. Food isn’t a good source of vitamin D, though. The best way to take adequate amounts of vitamin D is from sun exposure and food supplements.
Vitamin D deficiency has been linked to hair loss. Furthermore, vitamin D deficiency is pretty common among adults. Therefore, maybe it’s time to go for a walk under the sun! The human body synthesizes vitamin D when the skin is exposed to the sunlight.
Common causes of hair loss
Besides genetics, the most common causes of hair loss are physiological and emotional stress, medical conditions, and of course nutritional deficiencies. For instance, vitamins C & A, along with many minerals, such as copper, iron, and zinc are vital for the synthesis of collagen. Collagen is the most abundant protein in the human body and a key protein for hair structure.
Additionally, eating foods high in vitamin D and vitamin B12 is beneficial for your hair.
Is vitamin D good as a treatment for hair loss?
According to many studies, vitamin D deficiency has been linked to increased risk of hair fall. Participants with insufficient amounts of vitamin D in their body had greater chances of losing their hair![1,2,3]
Maybe decreased exposure to sunlight is an important reason for hair fall, after all.
Vitamin D sources
Skin exposure to sunlight is the most important way to boost your vitamin D intake. The human body can synthesize vitamin D when the skin is exposed to sunlight. Just 30 minutes per day are enough. Additionally, eat foods with vitamin E to protect your face from photoaging.
Foods aren’t good sources of vitamin D. Only cod liver oil is particularly high in vitamin D. Also, some fish, such as salmon, trout, mackerel, and tuna contain high amounts of vitamin D. Furthermore, plant-based foods lack of vitamin D. Only some mushrooms contain traces of vitamin D. More about foods high in vitamin D here.
