Hi Dave, thanks!
After taking the test, I realized that my ordinary Vitamin D supplementation, combined with the amount of time I spent in the sun, wasn’t sufficient, so I switched to 4000 IU Vitamin D/day. I’ve also switched from of the foods I eat to lower-fat version (e.g. cottage cheese that comes in three fat percentages at Trader Joe’s). I plan to have a follow-up test after some time passes - need to research when, for instance, the Vitamin D levels should be restored given the new supplementation regimen.
