We used to only associate Vitamin D with bone health. However, we now know that Vitamin D plays a much larger role in our overall health.
Vitamin D levels are commonly low in the general population due to the increased use of sunscreen since the 1980s. However, Vitamin D is essential to our mental and physical health. We have receptors in every tissue of the body for this vitamin and we need to maintain optimal levels to function at our best. It can help protect us against many illnesses, flu, cancer, heart disease, Alzheimer’s, and more.
Now there is evidence to suggest Vitamin D supplements may also reduce ADHD symptoms. A systematic review that was published in the Journal of Child and Adolescent Psychopharmacology looked at four randomized controlled trials (RCT’s) which included 256 ADHD children. The children that were taking Vitamin D supplements in conjunction with methylphenidate-based medication, appeared to have a greater reduction of ADHD symptoms compared to children who took a Vitamin D placebo. However, the study authors concluded that this is still low-strength evidence and additional RCT’s are needed to truly determine the efficacy and safety of Vitamin D supplements in conjunction with other ADHD treatments.
