- Velocity & Diffusion: Coverage exploded across 4 distinct news outlets with 4 published articles, achieving a live velocity of 2.
- Primary Driver: New research finds that taking vitamin D2 supplements can actually lower the body’s active vitamin D3 levels, raising safety questions.
- Source Integrity: Verified strictly against primary headline reporting under zero-hallucination protocols.
A recent study reports that consumption of vitamin D2 supplements can cause a reduction in circulating vitamin D3 levels. A meta‑analysis cited by UA.NEWS aggregates multiple trials and reinforces the inverse relationship, while United News of Bangladesh and ScienceDaily echo the warning.
The Times of India notes the question but provides no mechanism or clinical outcome, and coverage does not specify how large the D3 drop may be. Further investigation is needed to determine health consequences of lowered D3 from D2 supplementation.
