You've probably heard bacteria and viruses talked about like the enemy — but inside your gut, that's only part of the story. Researchers have found that many of the trillions of bacteria living in your digestive system aren't just harmless — they're actively working for you, supporting digestion, metabolism, and immune health.
Here's the part that surprises most people: viruses are in on it too. Scientists have discovered that most of the viruses in your gut don't target you directly — they target bacteria. These bacteria-infecting viruses, called phages, make up the vast majority of what's known as your gut "virome." Rather than being purely harmful, research shows some of these viruses actually help good bacteria stay resilient — supporting them against things like stress and environmental changes, in a genuinely cooperative relationship most people never hear about.
So what helps keep this whole system running well? According to current research, a big part of the answer is diet — specifically, foods rich in prebiotics, fermented foods, and plant-based nutrients, which support a healthy, diverse gut microbiome.
In the office, we often recommend Standard Process's Lactic Acid Yeast, ProSynbiotic, and GI Stability as part of a whole-food nutritional approach to supporting gut health, especially for patients who want additional support beyond diet alone. As with any supplement, we tailor recommendations to each patient's individual needs during a visit.
It's a good reminder that most of what's living in and on you isn't working against you — it's part of a genuinely complex, cooperative system. And simple, whole-food choices are one of the best ways to support it.
