I'm pre-band as well (6/30) and part of my research was to purchase a couple of the sample packs from Bariatric Advantage.
Bariatric Advantage - Adjustable Gastric Band Sample Kit
My sample included chewable Multivitamins in 2 flavors, calcium lozenges in 4 flavors, a calcium chew (chocolate) and some samples of the powdered calcium.....about $6 for the sample pack. I bought 2 to make it worth the shipping.
I highly recommend "splurging" on the sample pack if you are considering buying these. You can always feed the ones you don't like to your kids or dogs:unsure:.
I am sold totally on the chewable Vitamins and 2 of the 4 calcium lozenge flavors. The calcium powders were VILE (tasted like poorly flavored alka seltzer without the fizz) and the calcium chew didn't taste great enough to justify the cost or the fact that it has much less calcium than the lozenges (250 mg vs 400 mg for the lozenge).
I am ordering from BariatricChoice.com however as they have free shipping >$79, a 10% discount for orders >$99 and do have a return guarantee (still have to pay shipping/handling), but you can even return one opened package of any item you are unhappy with. (Disclaimer - I haven't actually taken advantage of this offer)
