Should I take a probiotic with antibiotics?

Yes, antibiotics kill off pathogenic bacteria in the body but unfortunately their sterility doesn't discriminate and they can also kill off favorable flora which can set up high risk for overgrowth of yeast or bad bacteria flare which can drive microbiome imbalance and undesired symptoms. Also research supports taking a probiotic when on an antibiotic can reduce GI stress, diarrhea, and mood imbalance.

Rodgers B, Kirley K, Mounsey A. PURLs: prescribing an antibiotic? Pair it with probiotics. J Fam Pract. 2013;62(3):148–150.

I recommend taking a probiotic at least 4 hours separate from your antibiotic dosage and following your antibiotic, it is best to double down on your probiotic for that length of time, meaning if you took a course for 10 days, you'd use your probiotic 1 at bed during those 10 days and then would take 2 at bed following the antibiotic for 10 days. 

If you are on antibiotics and you don't want long-term impact on your microbiome, you may consider adding in Restore Baseline Probiotic which is a two-strain 50:50 blend of cultures with flexible dosing that aids in mood stability, bloating, and GI stress. This is used in our Microbiome Rebook Bundle

How quickly should it take to experience results?

Some will experience immediate shifts in bloating and bowel regularity or intolerance if in a state of dysbiosis. The shifts you experience are likely based on your foundational microbiome status. The best way to assess efficacy is through doing my Probiotic Challenge to track benefits and changes. 

What if I don’t tolerate the probiotic?

If you don't tolerate the probiotic, you are likely in the state of dysbiosis and/or you may have histamine intolerance. Consider both the 10-day Detox and Beat the Bloat cleanse as ways to reset your body to aid in tolerance in the future. 

How do I know what formula of your probiotic line is best for me?

Great question! The probiotic challenge will help you determine if you'd benefit from Restore Baseline or Targeted Strength more, but you can check out this flow chart to determine which probiotic is best for you! Think of the Rebuild Spectrum as a diverse tool for immune and gut reset following antibiotic or gut cleanse. The GI Clean up is a unique probiotic used in active cleanse and for those with stubborn recurring dysbiosis or yeast flare. 

I ordered this supplement and it arrived at room temperature or slightly warm, is it still okay to use? 

Yes, all the probiotics in our line have guaranteed test confirmed viability of stated billions of colony forming units when stored air tight with temperatures up to 122 degrees. Once you receive it at home you may choose to keep your probiotics refrigerated or in a cool place like your vanity cabinet. I keep them in my bathroom as I have discovered the added obstacle of my kitchen fridge is one way I may miss my probiotic and when removing for travel etc. best to just keep room temp as the changes of cold to room temp over and over can actually breakdown the cellulose capsules more than desired with variance in condensation. 


This review demonstrates S. boulardii as a good biotherapeutic agent allowing to prevent and/or treat several gastrointestinal diseases. S. boulardii mediates effects which resemble the protective effects of the normal healthy gut flora.
