Redheads Need Less Vitamin D
Everybody needs Vitamin D to live a healthy life, but unlike many vitamins that are ingested, we get Vitamin D from exposure to natural sunlight. It’s not too surprising, then, that people with red hair require less Vitamin D, and are even able to produce it themselves within their body, as this is a genetic advantage in parts of the world where redheads are most common: places across Northern Europe where sunlight is scarce.
