Impression from hundreds of vitamin D clinical trials and studies
* Imagine the consequences of taking a years worth of any food, supplement, or drug in a single day: Examples: salt, water, iodine, aspirin, sugar, wheat, vitamin A, etc, etc. Vitamin D is perhaps the only item for which taking the annual amount in a single day will not cause a call to 911 or immediate death Vitamin D is not toxic when annual amount is taken in a single day, but problems of annual dosing outweigh the benefits.
