Common causes of hair loss
Besides genetics, the most common causes of hair loss are physiological and emotional stress, medical conditions, and nutritional deficiencies. For instance, vitamin A, vitamin C, or certain 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.
Vitamin D and vitamin B12 are beneficial for your hair as well.
Vitamin D deficiency may cause hair loss
According to many studies, vitamin D deficiency has been linked to increased risk of hair loss. Participants with insufficient amounts of vitamin D in their body had greater chances of losing their hair![1,2,3]
So, boosting the daily vitamin D intake may be beneficial for hair growth.
However, you should follow a well-balanced diet to help your hair regrow. Many nutritional deficiencies may cause fragile hair and eventually hair loss.
How to get vitamin D to prevent hair loss?
Most people need a daily dose of 600 IU of vitamin D.
Food isn’t a good source of vitamin D, though. Only cod liver oil is particularly high in vitamin D. Also, some fish, such as salmon, trout, mackerel, tuna, as well as eggs contain high amounts of vitamin D. On the other hand, plant-based foods lack of vitamin D. Only some mushrooms contain traces of vitamin D.
Nor can we rely on sun exposure to get adequate amounts of vitamin D. Sun exposure can be dangerous for the skin. For instance, it can cause skin aging.
The best way to take adequate amounts of vitamin D is from dietary supplements. You’ll find a wide variety of vitamin D supplements on iHerb.
Although high dosages of vitamin D from supplements are considered pretty safe, you shouldn’t exceed the maximum safe dose.
Always consult your healthcare provider before taking a dietary supplement.
