As a nurse, my advice, before "doctoring" yourself, is to get a complete physical!!!
Ask for a complete blood workup to include a complete thyroid profile, liver profile, AND vitamin D levels.
There may be more to your feeling of being sluggish and run down than just a lack of vitamins.
Back when I was a teen, you took GERITOL for your complaint!!! However, TODAY, your best advice is as stated above!
Good luck! And keep us informed!
