Totally Inert Packaging (TIP) is our multi-step approach to ensuring guaranteed potency through expiration for all of our probiotic supplements. We take these steps because it's important to minimize exposure. Because probiotic bacteria are living organisms, they have the same requirements for life as you or I -- without oxygen and water, probiotics cannot grow. Most probiotic bacteria have been freeze dried during production to keep them in metabolic stasis. As we introduce moisture and oxygen, the once dehydrated probiotic bacteria wake up and begin reproducing or colonizing. You want the probiotic bacteria to grow and colonize in your gut, not on the shelf. Therefore, preventing the ingress of moisture and oxygen during storage is essential to ensure that your supplements remain potent through their expiration date. Packaging Probiotics: After encapsulation, we pour our probiotic capsules into a glass bottle. We specifically use brown glass bottles for two reasons: They block UV light They allow less external moisture contamination Probiotic bacteria are as sensitive to UV radiation as you or I and amber glass bottles block more UV light than clear, green, or blue glass bottles. Additionally, glass bottles have a lower moisture-vapor transmission rate. What this means is that water can more readily pass through a plastic packaing barrier and increase the relative humidity inside a plastic bottle. Next, we add moisture and oxygen dessicant packets followed up by a pure nitrogen flush of the inside of each bottle. These packets absorb whatever leftover excess oxygen and moisture remaining inside the product after we flush the bottles with pure N2. By minimizing the oxygen and moisture content, we can guarantee that the probiotics within will remain inert until you're ready to start taking them! Lastly, we apply a double seal complete with another set of moisture and oxygen barriers to finish our TIP process. By limiting their exposure, we can guarantee that our supplements will remain stable and potent through expiration.

Yes, you can absolutely take probiotics with antibiotics! When should I give probiotics with antibiotics? While you can take antibiotics and probiotics at the same time, we recommend separating your probiotic supplement from your antibiotic by two hours. This separation will reduce the number of beneficial bacteria in your probiotic being killed by the antibiotic in your digestive tract. How long should I take probiotics after antibiotics? We recommend continuing to take a probiotic for approximately two weeks after your antibiotic regimen has completed. We recommend Theralac because our blend of Lactobacillus and Bifidobacteria probiotic bacteria will colonize your entire digestive tract. You can continue to support the growth of beneficial bacteria after antibiotics by eating a diet rich in high-fiber foods like fruits and vegetables. Why should I take a probiotic after antibiotics? You take a probiotic after antibiotics because an antibiotic will kill both the good and bad bacteria throughout your digestive tract. Beneficial microbes like probiotic bacteria support the healthy structure and function of your digestive tract and help your body digest food and absorb nutrients. Introducing a probiotic either during or after an antibiotic regimen will support microbial balance.
