These Symptoms Indicate That You Need More Vitamin B12

Hair Loss And Greying

In 2019, research in Dermatology Therapy determined that vitamin B12 is one of the four nutrients that could lead to premature hair loss (the others being iron, folate, and vitamin D). Vitamin B12 can even make peoples’ hair turn grey.

Hair follicles rely on vitamin B12 to remain healthy. When they do not receive enough nutrients, the follicles become discolored and fall out. In 2016, a report in the International Journal of Trichology found that even women younger than 25 can develop grey hairs because of a vitamin B12 deficiency.
