FWIW, your gut already synthesizes K2 from K1. K1 is easy to get from green leafy vegetables from spinach to broccoli, though I suppose easy to avoid if you don't eat well.
K2 from dietary doses of meat (MK-4) doesn't change circulating levels of MK-4 — it's basically not bioavailable. Though K2 from fermented products like cheeses and natto (MK-7) is bioavailable.
Doesn't seem like something worth worrying about if you have a varied diet that includes green veggies.
Unfortunately Dr Berg seems not to consider the concept of biological half-time. I am sure he know the concept, just forgot to put it into his calculation formula.
He basically assumes that if his patient consumes 2000 IU vitamin D today, then tomorrow his patient has depleted all 2000 IU and has zero vitamin D in patient's blood.
Yes. Had tons of random problems. Ended up being autoimmune Sjogrens and a clotting disorder.
Diet changes and supplements are how I got thing under control for most issues.
Blood thinners for Clotting since That’s way to dangerous, and no combination of anything else helped.
LDN covers symptoms when I’m not strict about diet.
Interesting. I had similar symptoms like migraine/brain fog, stiff neck and muscle tension as soon as October (winter in Central Europe) came. Tested for Vitamin D deficiency and had super low levels. Since taking supplements I feel good in winter for the first time in probably 5 years. I'm also a very outdoorsy person, so getting enough sun is not always a sure way wo have high levels of Vitamin D.
"Sun" is definitely not sufficient. Vitamin D synthesis requires UVB exposure [1] and that plummets to effectively zero in the higher latitudes in the winter: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5037520/#sec3-n... By "higher latitudes" I mean considered on a global scale; continental Europe is effectively all at these "higher latitudes".
Source. I used to have crippling migraines almost every day. I don’t anymore.
