With all this talk about Vitamin D and K deficiencies, which inevitable meanders onto Magnesium and fish oil supplements and whatnot; maybe it's time for a "vitamin subscription service"? Enter a bunch of information (location, lifestyle, diet, health issues) and get tailor made supplements sent to your home every month? The levels of some vitamins could vary depending on time of year (more D in winter) or circumstances (more Mg when more active in summer).

Ideally all packaged into one tablet or something. I take an unholy cocktail of supplements to help curb my migraines, that's 5 tablets/caps a day. Not much fun.
