Prebiotics and Probiotics: What’s the Difference?

As the old saying goes, two is better than one — and it definitely applies in the case of your daily probiotic. If you aren’t familiar with what prebiotics are or why they’re so helpful and essential for your good bacteria, we’re here to help clear up the confusion.


Prebiotics are specialized fibers that help nourish the bacteria living within the digestive tract; they’re not able to be digested by your body, so they hang out in the digestive tract and are the preferred food source for good probiotic bacteria.* Prebiotics help promote growth throughout the digestive tract and keep probiotic bacteria happy and healthy, encouraging them to stick around.*

You can find prebiotic fibers in foods like onions, garlic, Jerusalem artichokes, bananas, asparagus, jicama, and chicory root.

Many of the benefits of prebiotics are similar to those of probiotics. They help support diversity of your microbiome and can assist with digestive health.*

We believe so strongly in the benefits of prebiotics that we recently launched new Daily Prebiotic Fiber, a powder drink mix loaded with prebiotics to help keep the good bacteria in your gut nourished and working hard.* It tastes delicious (raspberry lemonade flavored!) and is easily mixed into your favorite beverages.


Probiotics, as we’ve discussed before, are the “good bacteria” that can provide numerous health benefits, including supporting your digestive and immune health.* You can incorporate probiotics into your day via supplements like Fortify or foods like yogurt, kimchi, and sauerkraut.

Fortify™ Daily Probiotics feature 30 billion live probiotic cultures per capsule and are formulated for daily care, women’s health, men’s health, and adults 50+.* If you need more support, try our Extra Strength line, which contains 50 billion live cultures per capsule.* All of these formulas also feature prebiotics, a food source for the good bacteria, so incorporate a daily dose into your wellness routine.*
