Not by me. I'm D-deficient, had gastric sleeve surgery, surprisingly it's the only deficiency I have regularly. I often forget my D... but been taking it religiously and asked my doctor if it's okay to add an extra 5000 iu per week, and he said it was fine and a good idea because of how low I normally run.
I've got a new formulation coming soon though that has vitamin k mixed in w/ 5000 ius, and a separate calcium/magnesium pill to make sure my bones stay strong. Will get re-tested next month and see if I beat the deficiency. I'm sure there's plenty of things but seemed like taking D probably is biggest (other than distancing) due to my already extremely low normal levels.
