So measuring your vitamin D levels before and after supplementation is the only way you're going to figure that out, right? Very important. If you don't measure it, you don't know. You can't know what you don't measure.

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.
I think that's excellent advice and, you know, most people don't get their vitamin D levels measured and I think that's exactly what people should do. You know, they should get their D levels measured before and after supplementation. Both.
There's quite a few, and, you know, there's several that affect your ability to convert... There's several steps in vitamin D3 metabolism but particularly vitamin D3...
I would say the SNPs is probably the big elephant in the room.
So measuring vitamin D levels before and after are very important.
get a vitamin D blood test do it you know after you're supplementing make make sure your your levels are adequate because again a lot of these single nucleotide polymorphisms and genes that affect our enzymes that are metabolizing vitamin D also affect how we respond to um supplemental vitamin D and some people can require a much higher dose than other people so really the key here is blood test and measuring um you don't know what you don't measure right
there are single nucleotide polymorphisms or variations in genes that affect people's ability to metabolize vitamin D3 and you know have it convert into this steroid hormone. Um, and so some people actually require a much higher dose and you'll never know that if you're supplementing with vitamin D and you don't get a blood test.
