When heartburn, acid indigestion, and gas team up after a big meal, Foster & Thrive Maximum Strength Antacid & Antigas Liquid gives you a straightforward way to feel more comfortable fast. This 12 oz bottle combines three trusted ingredients in a smooth liquid form that's easy to measure and simple to swallow, making it a practical pick for your medicine cabinet or travel bag.
