                                According to manufacturers and retailers, the primary ingredients in vape juice—propylene glycol (PG) and vegetable glycerin (VG)—are not derived from gluten-containing grains. This provides a strong basis for believing Elf Bars are gluten-free, but a closer look at flavorings is necessary for those with severe sensitivities, such as celiac disease.
