That stupid Cloudflare check page often adds latency in orders of magnitude compared to what a few thousand miles of cables would. Also most applications and websites are not that sensitive to latency anyway, at least when done properly.
AI boosters pose a bit of a Poe's Law problem; the poster here is probably joking, but also there almost certainly exist AI boosters gullible enough to actually believe something similar to that.
By what metric? Jeez. People, you need to get your blood checked. There is no one-fits-all dosage. In winter, 4000 IU/d was enough to raise my blood levels well into the excessive range.
My 4000 units were after blood testing and also after genetic testing which showed some VDR mutations that might benefit from supplementation. As mentioned in another comment, that dose brings me slightly over 30 ng/ml, so basically borderline ok.
I fully agree that supplementation should always be combined with both blood testing and also a general medical evaluation.
Current recommendations are 800 IU per day if you’re not significantly deficient. Always keep testing at least once a year or so. I took 5000 IU per day for a while, which ended up pushing me over 60 ng/ml. That’s considered too high a level and may have negative health effects.
I tested after taking 4000 IU daily for quite a while and ended up at 30.9 ng/ml, so I guess I have some buffer left. But I fully agree, regular testing is prudent when supplementing anything above common established levels.
