we do have the capacity to make the L but it's it's pretty pretty minimal
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.
And then you get I think of the L beta hydroxybutyrate as an important signaling molecule because you get higher concentrations of L in the brain.
Detabize very fast and L metabolize slower. Sorry.
So the D beta hydroxybutyrate gets metabolize like l like very very fast. So it gets in your system your tissues suck it up you metabolize it you do make your body makes very small amounts of L beta hydroxybutyrate with a rasmise enzyme. That rasmise enzyme is not in the liver but it's in the tissues. So that that's very interesting because I think some tissues are converting D to L to maybe use the L beta hydroxybutyrate as a signaling but I'm just speculating but nonetheless you have D gets metabolized very quickly and then the L is like a timed release version of beta hydroxybutyrate.
The L will get metabolized like three or four times slower and you get about 20 or% conversion of the L back to D but it's a very slow process.
