I backed down to 2000 iu's of D3 a night for a long time and a few months ago I upped it to 5000 iu's a night, and lost an additional 16 lbs. My daughter did too. My wife upped to 10,000 iu's a night and lost over 30 lbs in two months.
Please try to spray some magnesium oil on everynight and or take magnesium malate too. As D3 gobbles up magnesium like candy. And at least 1 Milligram of K2-mk4 3 times a day would be nice as it has synergy with D3.
Btw: I've had nosebleeds for years from a blotched surgery on my nose and the nose-bleeds have disappeared with the addition of K2.
