After getting all her poop euphemisms out of her system, Marissa digs into the latest data about probiotic supplements, which shows they are not only unhelpful, but possibly harmful as well.

Many Americans take probiotic supplements believing they will improve their digestion, relieve various conditions, and create a healthier gut. However, the preponderance of scientific data shows that for the vast majority of people, these supplements will do none of that. The latest data, actually shows that probiotic supplementation may actually be harmful by decreasing the diversity in our gut bacteria, thereby creating imbalances that can lead to a slew of health problems.

If you're concerned about your gut flora, your best bet is to consume foods that are rich in probiotics, like fermented foods such as sauerkraut, and yogurt. You also need to feed those bacteria by eating plenty of foods rich in fiber.
