In today’s post, I’m talking about a new study on Vitamin D and ADHD—and why this simple, low-cost intervention may meaningfully support attention, emotional regulation, and overall functioning in kids.
Here’s the referenced article if you’d like to read it yourself:

A Parent Visit That Got Me Curious
This whole topic landed on my radar because of a family I saw last week. It was a new visit to talk about their child’s ADHD. Before we even met, the mom had gone to a direct-to-consumer lab (you can order labs without a doctor now), checked a vitamin D level, and then started her son on vitamin D.
And before I had even sat down with them, he was doing much better—emotionally, behaviorally, and in terms of attention. He even said things felt better.
As someone who tends to be skeptical about any “quick fix,” I thought: Does it really make that big of a difference?
So I dug into the research. And sure enough, a brand-new article had just come out.
As an aside, our clinic, Frontier Pediatric Care, actually sees kiddos from around the country for their ADHD…we have expanded our license to include Nebraska, Iowa, Illinois, Florida, Texas, and Kansas and we take your insurance for these types of visits.
What the New Study Found
The 2025 paper, titled “The association between Vitamin D concentration and attention deficit hyperactivity disorder,” pooled data from 24,000 children—a massive dataset.
A few notable findings:
Kids with ADHD had lower vitamin D levels on average.
They didn’t dig into the “why,” but several theories exist.
