                                A 2020 study discovered that redheads have a more efficient capacity to produce their own vitamin D when exposed to low light conditions, an evolutionary advantage linked to the MC1R gene. This unique biological trait addresses the common query, do gingers produce their own vitamins, with a nuanced scientific explanation.
