Does multivitamin break a fast?
Quick answer
A multivitamin may not contain many calories, but some vitamins are better tolerated with food.
Step by step
01 Decide if your fast is strict, practical, medical, or religious.
02 Check whether multivitamin contains calories, sugar, protein, fat, or sweeteners.
03 If unsure, keep the fasting window simple and move multivitamin to your eating window.
The longer answer
A multivitamin may not contain many calories, but some vitamins are better tolerated with food. If it upsets your stomach, take it in your eating window. The useful rule is: strict fast = plain, zero-calorie drinks only; practical fast = small gray-area items may be okay if they do not trigger hunger or lead to extra calories.
Tip
Use Fast Goblin notes to mark gray-area choices like multivitamin, then compare hunger and consistency over a few fasts.
Common mistake
Assuming multivitamin is automatically fasting-safe without checking the label or your fasting goal.
Track in the app
Track whether you had multivitamin, the time, hunger level, and whether it made the fast easier or harder.
