QUOTE BOARD “The initial considerations for why vitamin D deficiency might be critical to the origins of asthma begin with the background knowledge that vitamin D deficiency is the most prevalent vitamin deficiency in the world. Between 60% and 100% of all individuals who do not take vitamin D supplements are considered vitamin D deficient, with the extent of deficiency varying according to the specific criteria used for defining it. This prevalence is particularly noteworthy during pregnancy and is especially pronounced among African American pregnant women.” “These results demonstrate a statistically significant reduction in asthma among offspring aged 3 and 6 years when comparing vitamin D supplementation (4400 IU/d) to the standard prenatal multivitamin with vitamin D (400 IU/d).” “Furthermore, these post hoc analyses found that vitamin D supplementation led to a decrease in total serum IgE levels and improved lung function in children compared to those whose mothers received a placebo alongside the standard prenatal multivitamin with vitamin D.” WHAT YOU NEED TO KNOW “It is now known that vitamin D has a myriad of nonbone effects that are important for overall health. Vitamin D has been found to exert profound effects on immune function, capable of modulating both the innate and adaptive immune responses. Moreover, vitamin D plays a critical role in the maintenance and completion of a healthy human pregnancy. During pregnancy, vitamin D helps in modulating the maternal immune system to reduce inflammation and prevent rejection of the fetus and enhance placental functioning and fetal organogenesis.” WHAT YOU NEED TO DO “We would recommend that all pregnant women consider a daily intake of at least 4400 IU vitamin D3 throughout their pregnancy, starting at the time of conception. It is worth noting that our detailed monitoring of potential adverse events found no attributable adverse events to vitamin D at this dose, during both 3-year and 6-year follow-up intervals, for both mother and child.” For more information and to order the Innate Choice® Vitamin D and the other Essential Nutrient System Supplements please visit www.eatwellmovewellthinkwell.ca.
