Birth Month May Affect Immune System Development

vitamin dI read about this new study this week and it kind of blew my mind. WebMD reported on a study published in the journal JAMA Neurology that showed that birth month can affect a baby’s vitamin D levels and immune system development.

Researchers studied vitamin D levels and white blood cell levels in cord blood samples from babies born in November and May. According to Web MD, “The study found that May babies had vitamin D levels roughly 20 percent lower than babies with November birthdays. The May babies also had roughly double the level of potentially harmful autoreactive T-cells than the November babies.” Those autoreactive T-cells could attack the body’s own cells, as they do with multiple sclerosis, a debilitating neurological condition.

This study, like many of its kind, did not reveal any causation but simply found a correlation between vitamin D and risk of MS. Since vitamin D is formed when the skin is exposed to the sun, it makes complete sense that May babies are low in this nutrient. As the mother of two spring babies, I now regret not paying more attention to my vitamin D supplementation while pregnant!

Did you take Vitamin D supplements while pregnant?
