Built to Actually Take, Not Just Swallow.

This is a swallowable tablet, not a chewable.
From Just One Buyers
“They are great! They taste like vanilla and don't make me burp like other brands.”
Kristy D.
“There is a subtle vanilla flavor to the vitamin with none of the typical vitamin taste!”
Amanda M.
“Everything I need in one pill. Very easy to swallow with a good flavor coating. I recommend this vitamin.”
Thaedra J.
“Taste amazing compared to other multivitamins that are hard to swallow without gagging. The vanilla scent really helps!! I wish these weren't so massive though but I can deal with it to take 1 per day vs 3x per day like some other brands.”

REASON 5
A Simple Routine For A Busy Life
Most complete bariatric regimens don't stop at a multivitamin. Iron gets dosed separately because it competes with calcium for absorption. B12 is often a second pill. Calcium needs its own timing.
Add it up, and a typical day of “complete” bariatric supplementation can mean several pills, at several different times.

One Tablet. Not a Handful.
Most complete bariatric regimens don't stop at a multivitamin. Iron gets dosed separately because it competes with calcium for absorption. B12 is often a second pill. Calcium needs its own timing, at least two hours from iron. Add it up, and a typical day of “complete” bariatric supplementation can mean several pills, at several different times, just to cover what one Just One tablet covers in a single dose.
