FAQs: Top Probulin Questions

At Probulin, we believe in education before supplementation. It’s important to know what we’re putting in our bodies, especially when the end goal is comprehensive digestive health.


If you’re new to Probulin probiotics or if you’re thinking of making the switch to Probulin, questions around the benefits of daily probiotics, efficacy, and shipping are all to be expected. In an effort to help you on your health journey, here’s a list of some commonly asked questions.

Probulin probioticsand beneficial bacteria in generalcan play an integral role in how to cleanse your digestive system. Probiotics support optimal digestion and regularity, immune function, and even offer relief from the discomfort of occasional gas & bloating.


In order to get the most out of your probiotic, it’s important to also know which foods have prebiotics, the fibers that serve as fuel to your friendly flora. Eating a diet rich in these fibers can enhance the health benefits of probiotics.

At Probulin, questions like this come in a fair amount. While our Total Care is a great formula for overall support, there are more targeted formulas for immune support, women’s health, colon care, and even children’s health. There’s truly a Probulin probiotic that’s perfect for everyone. We encourage you to browse our line of Probulin Probiotics to determine which formula is best for you.

When Probulin® probiotics leave our NSF® Certified cGMP facility, they often have a long journey to the customer. You may be wondering, do probiotics need to be refrigerated?


While Probulin probiotics are shelf-stable, it’s still best to avoid heat and moisture. Probiotic bacteria do not like extreme temperature changes; in fact, it kills them. That’s why our probiotics are packed inside a properly insulated box with ice, to provide stability for the probiotic bacteria throughout the journey.
