Levels went from 40 to 67.8 to 110 to 134 in three months (same timeframe as HBOT).
The evidence is convergent. Multiple independent sources reach the same conclusion, the underlying mechanism is well-characterized, and even the field's most cautious voices treat it as worth doing.

Every Sunday: the week’s new conflicts and verdict changes — and nothing else.
Native comments, Twitter mentions, and Reddit threads about this claim — surfaced together so the conversation isn't fragmented across platforms.
Bookmarking — the dossier-vs-overview split is the right call. Most of the time I want overview; sometimes I want receipts.
Would love a "what would change this verdict" RSS feed. Sign me up if it exists.
The liver converts vitamin D into 25-OH-D (the pre-active form we measure). This is an oxygen-reliant process. More oxygen = faster, more efficient conversion. Increased oxygenation also inhibits CYP24A1, the enzyme that degrades vitamin D.
HBOT may radically improve the bioavailability and systemic efficiency of vitamin D, a master regulator of longevity and cellular function.
In the kidneys, better perfusion supports the conversion of 25-OH-D into the active form 1,25(OH)₂D. This accelerates the activation-utilization cycle.
My Vit D levels spiked 235% post HBOT.
