resB® targets the gut-lung axis with a combination for clinically studied probiotic strains and bioactive botanicals.

The probiotic strains in resB® have been clinically studied for their gut, lung, and immune benefits. Curcuma longa (turmeric), Ocimum sanctum (holy basil), and Adhatoda vasica (vasaka) leaf extracts were added for their antioxidant and respiratory supportive properties, as well as their role in supporting a healthy inflammatory response.

The complete formula has been shown to support lung structure and function in preclinical studies.*

We stand behind our products and proudly offer a 30-day money-back guarantee. Please read more about our return policy HERE.

resB® Lung Support contains a unique combination of probiotic strains and botanicals, formulated by physician scientists based on over a decade of research on the gut-lung axis.

The scientists behind ResBiotic developed and tested probiotic strains independently, as a blend, and in combination with bioactive botanicals to arrive at the optimal formulation for resB® Lung Support.

That formula is precision blended in a cGMP environment by FDA-certified suppliers, specifically processed for extended stability and longevity, rigorously tested for the most stringent quality, purity, and safety measures, and delivered through a temperature-controlled supply chain to ensure a research-backed CFU (Colony Forming Unity) count in every capsule, every time.

All of resB® Lung Support’s ingredients are listed on the bottle. You can also read ingredient details on the product page, or direct any specific ingredient questions to our support team at

resB® Lung Support is for anyone 18+ who wants to prioritize their lung health.

While there are no known contraindications with resB® Lung Support and any over-the-counter or prescription medications, we encourage you to check in with your physician before adding new products to your regimen.

Additionally, if you are taking an antibiotic, take resB® at least 1 to 2 hours before or after your antibiotic dose.

Some GI discomfort can occur when taking probiotics, but these typically resolve within 2 weeks. Please consult a healthcare professional if symptoms worsen or persist.

If you are pregnant or breastfeeding, we recommend consulting your physician before taking resB® Lung Support.

You can take resB® Lung Support with or without food. If you miss a dose, just take two capsules the next time. The key is consistent daily use. You can read more about that here.

resB® Lung Support is manufactured in GMP-certified and FDA-registered facilities, right here in the USA.

While people often report gut health benefits as early as their first week, systemic benefits of probiotics can take longer. 

Some of our customers report breathing benefits within 6 days, others after 60. This variability can be attributed to a number of factors, including the importance of continuous daily use and the reality that some of us constantly think about our lungs while others breathe without much thought.

Probiotics are living microorganisms and proper storage is important to get all the health benefits.

Third party stability testing confirms that resB® can be stored at room temperature for weeks without loss of potency. That said, we recommend refrigerating resB® Lung Support if possible, and always storing in a cool, dry place.

We love staying organized too! Feel free to keep your resB® Lung Support in your pill organizer, as long as you pop the box in the fridge or store in a cool, dry place.

resB® Lung Support contains live probiotic bacteria strains that have been tested for survivability. Key tests include acid tolerance, bile salt tolerance, pepsin resistance, pancreatin resistance, and adhesion to human intestinal mucosa.

Translation: We made sure they'll stay alive, and get where they need to go.

There is no specific recommendation to take a prebiotic with resB® Lung Support, however many people find prebiotics beneficial for both their naturally existing flora as well as the supplemental probiotic. You can learn more about this topic, including common foods that contain high quantities of prebiotic fiber, in this post.
