Popular Supplements That Can Make Your Poop Even Smellier – Health Digest

Vitamins A, D, E, and K are among the kinds of supplements that can make our poop even smellier, reports Healthline. This is because, for some people, these vitamins can cause digestive discomfort as a side effect. Alternatively, fish oil supplements can also kick the stench of our poop up a notch (via Self). The nutrients in fish oil can latch on to fat in our stool that hasn’t been fully broken down, giving poop an even less-than-desirable smell.

Just like some of the food items we previously mentioned, some supplements can also be high in sulfur compounds. “Certain supplements like glucosamine, chondroitin, and garlic are high in sulfate, which the bacteria in the colon converts into sulfide gases,” Cleveland Clinic gastroenterologist Dr. Christine Lee told Health. Garlic supplements, in particular, have been linked with diarrhea as a smelly side effect, although this is more often seen in connection with raw garlic, according to Drugs.com.
