The D3 pills we take are labeled 1000 IU (25mcg) per pill. 10,000 IU per day is 10 such pills, and 10,000 mcg would be 400 such pills. I doubt whether anyone actually takes 10,000 mg of D3 per day.
Personally, I take 2 or 3 if I remember (most days not), and I haven’t had the flu for decades. No flu shots ever.
