I take 10000 D3 daily / K2 / magnesium. I get my D3 levels tested and they are at 75 ng/ml. I am shooting for 90 ng/ml. And no stinkin spike protein vaxxx for me! D3 is my vax, in a good way.

10000 units is the least expensive way to buy D3. Take this 3-4 times a week if one daily is too much for you. This one can be found at Amazon, though last time I bought two at Walmart on line.
Same here. Along with Quercitin.
