    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.*

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!

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.
