Thank You, Dr. Laderoute, for reiterating that Vitamin-D is a currency of immune system economy, which we can readily provide, to keep our immune system functioning as designed. Some people, such as those who have had gallbladders removed, and many with a lot of body fat (into which vitamin-D diffuses) may need to take 10,000 units per day to get a mid-normal range blood level. Most people over 100# will be well served by 5000 units per day.

Checking a blood level after 3 months on a steady dose is a good idea.

Vitamin K2 seems to be synergistic with vitamin-D in many ways. I don't readily find study information on that, though. I personally take both.

If you read between the lines of this article [Barale C, Cavalot F, Frascaroli C, Bonomo K, Morotti A, Guerrasio A, Russo I. Association between High On-Aspirin Platelet Reactivity and Reduced Superoxide Dismutase Activity in Patients Affected by Type 2 Diabetes Mellitus or Primary Hypercholesterolemia. Int J Mol Sci. 2020 Jul 15;21(14):4983. doi: 10.3390/ijms21144983.] the induction of sCD40L by aspirin in familial hypercholesterolemia (FH) and in T2D seems to be blocked by statins. There should be a warning on the low dose aspirin where it currently says "Call 911, then chew 2 tablets (of aspirin 81 mg), if you think you are having a heart attack. Aspirin may help save your life." They need to add, use in patients with FH or T2D who are not on statin therapy may increase platelet activation (elevates sCD40L) which could worsen clotting and thus cardiovascular symptoms.
