IMO even for COVID protection you really don't need more than 5000 IU. Also using for COVID protection is temporary, too. As long as you're checking the right things you'll be fine.Thanks Gents
I've read that 8000iu or less is safe for the large majority of individuals and doses over 4000iu per day may help protect against COVID. I travel often. Stan Efferding, Dr. Joel Gould, and Dr. Mark Gordon, among others, suggest "high" levels of supplementation. I only get 10-20mins of sun a day. Either way I'll be getting my d3 levels checked on bloodwork, my serum calcium is usually middle of the range. Will also check for zinc, selenium and copper. I'm assuming that my iron is fine since i'm running pretty high hematocrit(live at high elevation unfortunately). I can PM you some links when I dig them up, if you'd like.
For K2 I've been trying to eat Natto, but its pretty rough. I'm thinking of sourcing some emu oil, otherwise I know i'm over 100mcg from my dietary sources but barely and was thinking 300-400mcg would be better. I prefer to get what I need from foods. I may get ongoing dexa scans for lbm and bone density.
IMHO the suggested guidelines for most micros are low.
Vitamin K2 get Healthy Origins brand K2 (MK-7) 100 mcg capsules. Super easy, third party tested for quality by ConsumerLab.
