Despite how companies are trying to advertise that everyone needs probiotic supplements to optimize their health, solid medical and scientific data suggests otherwise.
You see, our gut has trillions of microorganisms that help the gastrointestinal tract in several functions, including the breakdown of indigestible foods, protecting the body from pathological organisms, and producing some nutrients (e.g., vitamin K).
Generally speaking, there is a balance between the gut flora and the immune system, which is referred to as symbiosis. However, when this equilibrium gets disrupted, problems begin.
The main way to maintain a healthy gut flora and prevent infections is by consuming a balanced diet that’s rich in fiber and good probiotics.
Fiber is typically found in green leafy vegetables, fruits, and whole grains, which is the reason that vegans rarely need to take probiotic supplements.
As you probably deduced, the answer to our main question is no. Not everyone needs to take supplements, especially if they’re on a healthy, balanced diet.
