The Claim

Three specific genetic variants (SNPs) in the PPARG gene — rs1151996, rs1175540, and rs1175544 — are significantly associated with baseline vitamin D levels (25-(OH)D) in healthy adults aged 50–74, with p-values of 0.01, 0.02, and 0.03 respectively, suggesting a genetic influence on vitamin D status in this population.

What the research says

Supports is higher

Support is ahead, but a single strong opposing study can change this.

Supports

Challenges
0score

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

Correlation
1 study reviewed
In plain English

Scientists found that three tiny differences in a person’s DNA, all in the same gene, are linked to how much vitamin D they naturally have in their body when they’re healthy and between 50 and 74 years old.

1 study
  1. Study: Vitamin D, leptin and impact on immune response to seasonal influenza A/H1N1 vaccine in older persons

    The study found that three specific gene variations are linked to how much vitamin D people have in their blood, which is exactly what the claim says.
