  • How it Works

    The Gut-Lung Axis
    The probiotic bacteria in resB® have been known to produce specific short chain fatty acids that support digestive health directly and travel through systemic circulation to support respiratory health.*

    The Gut-Immune Connection
    Did you know 70% of your immune cells live in your gut? The probiotic bacteria and botanicals in resB® have also been clinically studied for their immune supportive benefits.*

What's Inside

  • Probiotic Blend

    Our respiratory-specific, multi-strain probiotic blend contains Lactiplantibacillus plantarum RSB11™, Lactobacillus acidophilus RSB21™, and Lacticaseibacillus rhamnosus RSB13™, which work together to target the gut-lung axis.*

  • Vasaka Leaf

    Vasaka, also known as Adhatoda vasica or malabar nut, is a respiratory remedy in the Ayurvedic and Unani traditions. Scientists have isolated two key alkaloids, vasicine and vasicinone, in vasaka leaf to better understand how vasaka supports healthy breathing.*

  • Turmeric Root

    Turmeric (Curcuma longa) root is known to have a wide range of health benefits. Its respiratory uses are well-documented in the Ayurvedic tradition. More recently, scientists have explored turmeric's immune-supportive and antioxidant properties.*

  • Holy Basil

    Ocimum tenuiflorum, commonly known as holy basil or tulsi, is also a rockstar of the Ayurvedic tradition, historically used to support a healthy immune system. Scientific inquiry suggests this ancient herb also has adaptogenic and antioxidant properties.*

Asked & Answered

Anyone 18+ who wants to prioritize their gut, lung, and immune health!

resB® is a top physician recommended, physician formulated supplement for continuous respiratory care. Several customers use resB® for chronic regulation of respiratory structure and function, in addition to cough relief, lung detox and mucus relief.

resB® was designed based on over 10 years of rigorous research, to support healthy respiratory structure and function, healthy digestion and to boost immune system, while keeping everyone in mind.

Our ingredients and products have been studied extensively in many settings, including actual physician supervised pre-clinical and clinical trials, in specific conditions!

With that said, no supplement can make claims regarding any specific disease diagnosis. We recommend that you check with your doctor or pharmacist before starting any new dietary supplement.

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 prescribing 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. This is to ensure your antibiotic doesn't kill the probiotic bacteria in resB® before they have a chance to work!

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.

resB® Lung Support is precision blended in a cGMP environment and FDA-registered facilities, right here in the USA.

The formula is 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 Unit) count in every capsule, every time.

resB® was also created with smokers, and their lung health in mind. Our clinical trials included smokers who developed lung problems such as asthma, COPD. We strongly encourage smokers to try quitting smoking to take control of their lung health.

We stand behind our products and proudly offer a 30-day money-back guarantee on your first purchase. You can read more about our return policy here.
