Витамин D

For this reason, lower levels of Vitamin D could feasibly lead to differences in the developing brain's wiring, which might explain the higher rates of mental illnesses like schizophrenia or depression among people born in the winter. The idea is still very much a hypothesis, although some fortuitous evidence comes from Denmark. Soon after they are born, every Danish baby is pricked on their heel, and a small spot of dried blood is kept as a record of their health at the moment they enter the world. Analysing this data for people born in the early 80s and early 90s, researchers found that those with the lowest levels of Vitamin D at birth were more likely to develop schizophrenia later in life.
