                                According to nutrition labels for some brands, a serving of chewable multivitamins or antacids can contain anywhere from 5 to 20 calories, confirming that the question, "Do chewable tablets have calories?" is answered with a definitive 'yes'. This might be a surprise to those who assume all supplements are zero-calorie. However, the caloric content is typically derived from inactive ingredients, not the active vitamins and minerals themselves.
