Frequently Asked Questions

What is the difference between probiotics and prebiotics?

Probiotics are living microorganisms that provide a health benefit, and prebiotics are the foods that feed them. Prebiotics stimulate the growth of good microorganisms in the gut. Prebiotics are naturally found in beans, onions, bananas, and whole grains.They’re even present in breast milk. Prebiotics aren't digested by humans, so they can pass through your system to reach the bacteria in your gut that consume them.

Nature’s Way has both prebiotics and probiotics in supplement form including Fortify® 30 Billion Daily Probiotic. Alternatively, you can get standalone probiotics without prebiotic from both our Fortify and Pearls ranges.

Are Fortify products potent?

Nature’s Way Fortify probiotics are guaranteed to be potent through their expiration date. After expiration date, they lose potency. Each bottle is marked with the expiration date, so you’ll always know when you have living cultures at the labeled amount. While many probiotics require refrigeration to maintain potency, most Fortify probiotics do not. Check the packaging for storage directions.

Can I take Fortify products twice a day?

Nature’s Way Fortify probiotics are formulated to support digestive and immune health with a single daily dose.* Every probiotic capsule is delayed release to allow delivery of living cultures to the intestine where they are needed. Always refer to the label for product usage recommendations and consult a healthcare practitioner to determine if a product is right for you.

Can men and women take Fortify products?

We offer Nature’s Way Fortify probiotics in several formulations with varying numbers of live cultures per capsule. Some, like the Fortify® 30 Billion Daily Probiotic or the Fortify® Optima® Adult 50+ 50 Billion Probiotic, are formulated for both adult men and women.
