Vitamin D3 During Pregnancy and Cognitive Performance at 10 Years

What commenters are saying

Commenters shifted focus from the inaccessible study to broader vitamin D and sun exposure themes. Top discussion centers on whether modern indoor lifestyles (cars, AC, office work, screens) have caused population-level vitamin D deficiency with downstream effects on cognition, health, and productivity. One commenter noted a study finding sun avoidance mortality risk comparable to smoking. Specific pushback: the study was conducted in Denmark with limited sun already, and dosage recommendations derived from white populations may not apply to darker-skinned individuals who require higher vitamin D thresholds. Another corrected this, noting darker skin requires more sun exposure to achieve the same vitamin D, not inherently more vitamin D. Minor critique: US-based studies face fewer generalizability questions than non-US ones, though one replied that the US has greater climate and population diversity.
