An education on vitamins...a vita-cation.

At my last appointment with my dietician we discussed vitamins. After weight loss surgery, patients must commit to taking vitamin and mineral supplements for the rest of their lives or unwanted complications could occur. Patients who have these surgeries eat less food and consume fewer calories, therefore the body gets few nutrients. This is especially true for patients who have had the gastric bypass (Roux-en-Y) which is the procedure that I am looking into. 
My current vitamin regime includes: 2 chewable multivitamins 1000 mg Calcium 4000 IU Vitamin D 5000 mcg Biotin 50,000 IU Vitamin A
These vitamins were recommended by my surgeon after I had all of my labs drawn and deficiencies were noted in Vitamin D & A, which isn't able normal for those of us who live in Michigan. Almost all Michiganders are Vitamin D deficient. Anyways, my typical dosing included taking all the vitamins with breakfast. At my appointment, I learned that this is not the correct method of taking vitamins. 

First, all multivitamins (MVI) have iron. Calcium can not be taken with multivitamins because the iron won't all the calcium to absorb. MVI's and Calcium supplements should be taken at least 2 hours apart. Also, the calcium and vitamin D supplements should be divided because the body can only absorb so much at a time. Therefore, my new vitamin regime is:
Breakfast Calcium 500 mg (1/2 dose) Vitamin D 2000 IU (1/2 dose) Biotin 5000 mcg
Lunch Multivitamin
Dinner Calcium 500 mg (2nd 1/2 dose) Vitamin D 2000 IU (2nd 1/2 dose) Vitamin A 50,000 IU
My next challenge is to find all of these vitamins in a chewable form - not gummy, but chewable. Liquid form is okay to. Any suggestions? My first stop will likely be the Vitamin Shoppe.  At my appointment, I learned that I have lost around 7 lbs since this process started. My highest weight (HW) was 310 lbs. I am currently 303.2 lb. However, this was before we ate a ton of food at the Grand Hotel. I am still off Diet Coke however, which is a huge accomplishment. Over a month and going strong.
