So women who took supplementation and reached the threshold for normal levels after being deficient lost more weight.
As a dieting man with a Vitamin D deficiency, I'd like to see a study on men. Either way, maybe I should take more than 2800 iu daily.

So, tanning _will_ make you literally look slimmer!

Do you get tested for your Vitamin D levels every 3 months? You can take 10,000 IU a day. Some docs prescribe one dose of 50,000 IU once a week. Talk to your doc if your levels aren’t going up much with your current dose.

I take 4400 IU daily, 4000 IU as D3 and another 400 IU in a multivitamin which may be D2 or D3. IIRC, D2 needs a pass through the kidneys. When they do the serum assay it can be expressed as ng/ml, nanograms per milliliter or nmol/l, nanomoles per liter. Those units are not the same. Find out what units are being used and what's the normal range for serum 25(OH)D.
