vitamin D3

Based upon my Doctor's report of low D during a routine check-up 15 years ago, I began taking 10,000 IU's of D3 daily. Since then, I have had 1 cold and no flu infections in that time. I have had 3 very small heart blockages (with a family history of cardiac problems and family history of hypercholestrimia) and began taking K2 MK-7, Qunol coq-10, chelated magnesium, methyl B-12, Acetyl L carnitine, efa and dha supplements. I am 73 and have lowered by BP and blood cholesterol levels significantly. I had a very mild covid infection in November of 2020 with no long term side effects. I am convinced that D3 is the primary reason that I have been so healthy into my 70's.
